Conclusion + +The API Client Architecture Refactor proposed in TDS-100 is a well-designed +solution that fully addresses the requirements specified in Issue #100. The +design aligns perfectly with the user's provided code snippets and design +philosophy, introducing the `APICalling` event and `iModel` abstraction while +clarifying how `Endpoint` interacts with HTTP clients. + +The decision to have `Endpoint` manage `aiohttp.ClientSession` directly rather +than using/refactoring `AsyncAPIClient` is reasonable, though an adapter pattern +could further improve this aspect. The event-based architecture provides a clean +separation of concerns and improves testability, while the comprehensive +resource management ensures proper cleanup of async resources. + +The phased migration approach is well-thought-out and reduces implementation +risk. The open questions identified in the TDS should be addressed before or +during implementation, particularly regarding token estimation for rate +limiting. + +Overall, this is a high-quality design that will significantly improve the +cohesion and clarity of the API client, executor, and queue components.

This resulted in +poor performance and potential deadlocks.\ +**Recommendation:** Replace all synchronous file operations with asynchronous +ones using the aiofiles library. + +```python +# Before: Synchronous file operations +with open(file_path, "w", encoding="utf-8") as f: + f.write(text) +``` + +```python +# After: Asynchronous file operations +async with aiofiles.open(file_path, "w", encoding="utf-8") as f: + await f.write(text) +``` + +#### Issue 2: Inconsistent Async/Await Usage + +**Location:** `src/khive/services/reader/reader_service.py:77-87`\ +**Description:** The handle_request method was defined as async, but it was +calling synchronous methods, which can lead to unexpected behavior.\ +**Impact:** This inconsistency was causing issues with how the response was +handled, potentially leading to coroutine objects being returned instead of +actual results.\ +**Recommendation:** Ensure all methods called from async methods are also async +and properly awaited. + +```python +# Before: Inconsistent async/await usage +async def handle_request(self, request: ReaderRequest) -> ReaderResponse: + if request.action == ReaderAction.OPEN: + return self._open_doc(request.params) # Not awaited! + # ... +``` + +```python +# After: Consistent async/await usage +async def handle_request(self, request: ReaderRequest) -> ReaderResponse: + if request.action == ReaderAction.OPEN: + return await self._open_doc(request.params) # Properly awaited + # ... +``` + +### 8.2 Improvements + +#### Improvement 1: Persistent Document Storage + +**Location:** `src/khive/services/reader/reader_service.py:76-85`\ +**Description:** Implemented persistent storage for documents in a dedicated +cache directory (.khive/reader_cache/) instead of using temporary files in +memory.\ +**Benefit:** Documents are now persisted between server restarts, making the +service more robust and reliable.\ +**Suggestion:** Consider adding a TTL (time-to-live) mechanism to automatically +clean up old documents from the cache. + +```python +# Before: Using temporary files +temp_file = tempfile.NamedTemporaryFile( + delete=False, mode="w", encoding="utf-8" +) +temp_file.write(text) +doc_len = len(text) +temp_file.close() + +# store info +self.documents[doc_id] = (temp_file.name, doc_len) +``` + +```python +# After: Using persistent storage +# Create cache directory if it doesn't exist +self.cache_dir = Path.cwd() / ".khive" / "reader_cache" +self.cache_dir.mkdir(parents=True, exist_ok=True) + +# Path to the index file +self.index_path = self.cache_dir / "index.json" + +# Create a file in the cache directory +file_path = self.cache_dir / f"{doc_id}.txt" + +# Write to file asynchronously +async with aiofiles.open(file_path, "w", encoding="utf-8") as f: + await f.write(text) +``` + +#### Improvement 2: Enhanced Error Handling + +**Location:** `src/khive/services/reader/reader_service.py:153-156`\ +**Description:** Added more comprehensive error handling for file operations, +including checking if files exist before attempting to read them.\ +**Benefit:** Provides clearer error messages and prevents unexpected exceptions +when files are missing or inaccessible.\ +**Suggestion:** Consider adding logging for errors to aid in debugging. + +```python +# Before: Limited error handling +try: + path = Path(path) + content = path.read_text(encoding="utf-8")[s:e] +except Exception as ex: + return ReaderResponse(success=False, error=f"Read error: {ex!s}") +``` + +```python +# After: Enhanced error handling +try: + # Check if the file exists + if not file_path.exists(): + return ReaderResponse(success=False, error=f"File not found: {file_path}") + + # Read the file content asynchronously + async with aiofiles.open(file_path, mode='r', encoding='utf-8') as f: + # ... +except Exception as ex: + return ReaderResponse(success=False, error=f"Read error: {ex!s}") +``` + +### 8.3 Positive Highlights + +#### Highlight 1: Proper Async File Operations + +**Location:** `src/khive/services/reader/reader_service.py:158-167`\ +**Description:** Implemented proper asynchronous file operations using the +aiofiles library, which prevents blocking the event loop.\ +**Strength:** This implementation follows best practices for asynchronous +programming in Python, ensuring efficient and non-blocking I/O operations. + +```python +# Excellent async file reading implementation +async with aiofiles.open(file_path, mode='r', encoding='utf-8') as f: + # If we need the whole file + if s == 0 and e == length: + content = await f.read() + else: + # For partial reads, we need to read up to the end offset + content = await f.read(e) + # Then slice to get the start offset + content = content[s:] +``` + +#### Highlight 2: Improved Response Structure + +**Location:** `src/khive/services/reader/reader_service.py:175-182`\ +**Description:** Improved the response structure to properly use the +ReaderReadResponseContent class with a chunk field, ensuring consistency with +the expected response format.\ +**Strength:** This ensures that the response structure matches the expected +format defined in the parts.py file, making the API more consistent and +reliable. + +```python +# Well-structured response creation +# Create a PartialChunk object +chunk = PartialChunk(start_offset=s, end_offset=e, content=content) + +# Return the response with the chunk in the content field +return ReaderResponse( + success=True, + content=ReaderReadResponseContent(chunk=chunk), +) +``` + +## 9. Recommendations Summary + +### 9.1 Critical Fixes (Must Address) + +1. Add automated tests for the reader service to ensure the fixes are robust +2. Implement proper error handling for network issues when fetching remote + documents + +### 9.2 Important Improvements (Should Address) + +1. Add a TTL (time-to-live) mechanism to automatically clean up old documents + from the cache +2. Implement streaming for large file reads to reduce memory usage +3. Add logging for errors to aid in debugging + +### 9.3 Minor Suggestions (Nice to Have) + +1. Extract file operations into a separate utility class +2. Add more specific exception types for different error scenarios +3. Implement retry logic for transient errors + +## 10. Conclusion + +The implementation of asynchronous file operations in the khive reader service +has successfully addressed the issues with mixing synchronous and asynchronous +code. The changes have significantly improved the performance and reliability of +the service by preventing the event loop from being blocked during file +operations. + +The addition of persistent storage for documents in a dedicated cache directory +has also enhanced the robustness of the service, allowing documents to be +preserved between server restarts. The improved error handling and response +structure have made the API more consistent and reliable. + +While there are still some areas for improvement, particularly in terms of +automated testing and advanced features like TTL for cache cleanup, the current +implementation provides a solid foundation for the reader service. The changes +demonstrate a good understanding of asynchronous programming principles in +Python and follow best practices for file operations in an async context. + +Overall, this implementation is a significant improvement over the previous +version and should serve the needs of the khive project well. diff --git a/.khive/reports/crr/CRR-81.md b/.khive/reports/crr/CRR-81.md new file mode 100644 index 0000000..21e8cf1 --- /dev/null +++ b/.khive/reports/crr/CRR-81.md @@ -0,0 +1,486 @@ +--- +title: Code Review Report - Async API Client +by: khive-reviewer +created: 2025-05-18 +updated: 2025-05-18 +version: 1.0 +doc_type: CRR +output_subdir: crr +description: Code review of the robust async API client implementation for Issue #81 +date: 2025-05-18 +--- + +# Code Review: Async API Client + +## 1.

The +integration tests for the AsyncAPIClient with resilience patterns are also +well-implemented, though the Endpoint integration tests are currently skipped. + +There are no critical issues that need to be addressed before merging. The main +recommendations are to implement the skipped Endpoint integration tests and fix +the warning about coroutine 'AsyncMockMixin._execute_mock_call' never being +awaited.

Overview + +### 1.1 Component Purpose + +The `khive new-doc` command +([`src/khive/cli/khive_new_doc.py`](src/khive/cli/khive_new_doc.py:0)) is used +to scaffold new documentation files from predefined templates. This enhancement +aims to improve its usability by providing clearer, more informative error +messages when common issues occur. + +### 1.2 Design Reference + +This implementation is based on the requirements outlined in Issue #103. No +separate formal technical design specification (TDS) exists for this specific +enhancement, as it's a refinement of an existing command. + +### 1.3 Implementation Approach + +The approach will follow Test-Driven Development (TDD). + +1. **Identify Error Scenarios:** Analyze the current logic in + [`src/khive/cli/khive_new_doc.py`](src/khive/cli/khive_new_doc.py:0) and + [`src/khive/commands/new_doc.py`](src/khive/commands/new_doc.py:0) to + pinpoint potential failure points. +2. **Write Failing Tests:** For each scenario, write unit tests in + [`tests/cli/test_khive_new_doc.py`](tests/cli/test_khive_new_doc.py:0) that + expect specific, user-friendly error messages (for both standard and JSON + output). These tests will initially fail. +3. **Implement Error Handling:** Modify the command's code to detect these error + conditions and raise/return the improved error messages. +4. **Refactor (if needed):** Ensure the code remains clean and maintainable. + +## 2. Implementation Phases + +### 2.1 Phase 1: Error Scenario Identification & Test Definition + +**Description:** Review the `khive new-doc` codebase +([`src/khive/cli/khive_new_doc.py`](src/khive/cli/khive_new_doc.py:0) and +[`src/khive/commands/new_doc.py`](src/khive/commands/new_doc.py:0)) to list all +relevant error scenarios. Define the expected error messages and JSON output +structure for each. **Key Deliverables:** + +- A documented list of error scenarios. +- Drafts of new unit tests in + [`tests/cli/test_khive_new_doc.py`](tests/cli/test_khive_new_doc.py:0) for + each scenario (these will fail initially). **Dependencies:** Access to the + current codebase. **Estimated Complexity:** Medium + +### 2.2 Phase 2: Error Handling Implementation + +**Description:** Modify +[`src/khive/cli/khive_new_doc.py`](src/khive/cli/khive_new_doc.py:0) and/or +[`src/khive/commands/new_doc.py`](src/khive/commands/new_doc.py:0) to implement +the improved error handling and messaging. This will involve adding `try-except` +blocks, conditional checks, and crafting the error strings. **Key +Deliverables:** + +- Updated Python code with new error handling logic. +- Passing unit tests for all new error message scenarios. **Dependencies:** + Phase 1 completion. **Estimated Complexity:** Medium + +### 2.3 Phase 3: JSON Output Refinement & Final Testing + +**Description:** Ensure that when `--json-output` is used, errors are +consistently reported with a `status: "error"` field and a descriptive `message` +field.

Implementation Details + +The key issue is that when Hypothesis generates test data, it can include +special characters that need to be escaped in CSV format. The Python CSV module +requires an `escapechar` parameter to handle these special characters. + +The fix was to add a default `escapechar` parameter to both the `to_obj` and +`from_obj` methods in the `CsvAdapter` class: + +```python +# In to_obj method +csv_kwargs = dict(escapechar='\\') +csv_kwargs.update(kw) # User-provided kwargs override defaults +writer = csv.DictWriter(buf, fieldnames=items[0].model_dump().keys(), **csv_kwargs) + +# In from_obj method +csv_kwargs = dict(escapechar='\\') +csv_kwargs.update(kw) # User-provided kwargs override defaults +reader = csv.DictReader(io.StringIO(text), **csv_kwargs) +``` + +This ensures that any special characters in the data are properly escaped, while +still allowing users to override the default escape character if needed. + +## 8. Search Evidence + +- Search: pplx-1 - "python csv escapechar" - Found information about the + `escapechar` parameter in Python's CSV module and how it's used to escape + special characters in CSV data. The documentation states that if `escapechar` + is not specified and special characters are present in the data, a + `_csv.Error: need to escape, but no escapechar set` error will be raised. diff --git a/.khive/reports/ip/IP-24-neo4j-test-fix.md b/.khive/reports/ip/IP-24-neo4j-test-fix.md new file mode 100644 index 0000000..eeba91c --- /dev/null +++ b/.khive/reports/ip/IP-24-neo4j-test-fix.md @@ -0,0 +1,106 @@ +--- +title: "Implementation Plan: Fix Neo4j Adapter Tests" +by: "pydapter-implementer" +created: "2025-05-04" +updated: "2025-05-04" +version: "1.0" +doc_type: IP +output_subdir: ips +description: "Plan to fix failing tests in test_neo4j_adapter_extended.py" +--- + +# Implementation Plan: Fix Neo4j Adapter Tests + +## 1.

Introduction + +### 1.1 Research Objective + +This research aims to evaluate the proposals outlined in Issue #104 concerning +the improvement of CI enforcement and `khive` CLI integration. The primary goals +are to investigate the feasibility of a unified CI script, enhancements to +`khive ci`, modifications to Khive mode prompts for better CLI adherence, and +the potential to reduce reliance on the GitHub MCP server. The final output will +be this report (`RR-104.md`) with actionable recommendations. + +### 1.2 Methodology + +The research methodology involves: + +1. Reviewing the proposals in Issue #104. +2. Conducting targeted searches using `khive info search --provider perplexity` + for each key research area. +3. Leveraging deep research documents provided by the user for specific topics. +4. Analyzing search results and research documents to extract best practices, + pros, cons, and technical considerations. +5. Synthesizing findings into this report, with inline citations for all claims. +6. Developing recommendations based on the evidence gathered. + +### 1.3 Context + +The proposals in Issue #104 aim to streamline development workflows, improve +local development consistency with CI processes, and potentially reduce external +dependencies by enhancing the capabilities and usage of local `khive` CLI tools. +This aligns with the project's goal of efficient and robust development +practices. + +## 2. Technical Analysis + +### 2.1 Unified CI Script (`ci.sh`) + +**Objective:** Research best practices for creating a common CI script usable by +both a local `khive ci` command and GitHub Actions. + +**Findings:** A common CI script, typically a shell script (e.g., `ci.sh`), can +promote consistency between local development environments and the CI/CD +pipeline. + +**Best Practices & Structure:** + +- **Modularity:** Divide the script into distinct functions or stages (e.g., + `setup_env`, `lint`, `test`, `build`, `deploy`). This allows for selective + execution and easier maintenance. For example, `khive ci` could call specific + functions, while GitHub Actions could call the entire script or specific + stages. (pplx:3cc09674-62e2-4ed6-865b-2c291a3a0ce7, [1][5]) + ```bash + #!/bin/bash + # ci.sh + + setup_env() { + echo "Setting up environment..." + # e.g., install dependencies + } + + lint() { + echo "Running linters..." + # e.g., pre-commit run --all-files + } + + test() { + echo "Running tests..." + # e.g., pytest + } + + # Main execution logic + case "$1" in + setup) + setup_env + ;; + lint) + lint + ;; + test) + test + ;; + all) + setup_env + lint + test + ;; + *) + echo "Usage: $0 {setup|lint|test|all}" + exit 1 + ;; + esac + ``` +- **Error Handling:** Implement robust error handling using `set -euo pipefail` + at the beginning of the script. This ensures that the script exits immediately + if a command fails, an unset variable is used, or a command in a pipeline + fails. (pplx:3cc09674-62e2-4ed6-865b-2c291a3a0ce7, [5]) +- **Environment Detection:** The script should be able to detect whether it's + running in a local environment or a CI environment (e.g., by checking for + CI-specific environment variables like `CI`, `GITHUB_ACTIONS`). This allows + for conditional logic, such as skipping interactive prompts in CI. + (pplx:3cc09674-62e2-4ed6-865b-2c291a3a0ce7, [1]) + ```bash + if [[ -n "$GITHUB_ACTIONS" ]]; then + echo "Running in GitHub Actions CI environment." + # CI-specific logic + else + echo "Running in local environment." + # Local-specific logic + fi + ``` +- **Parameterization:** Allow parameters to be passed to the script to control + its behavior (e.g., `./ci.sh --stage=test`, or `./ci.sh test`). This is + crucial for flexibility. +- **Idempotency:** Design script stages to be idempotent where possible, meaning + running them multiple times produces the same result. +- **Logging:** Implement clear and consistent logging to help debug issues both + locally and in CI. +- **Tooling Checks:** Ensure necessary tools (linters, test runners) are + installed or provide clear instructions/scripts to install them. +- **GitHub Actions Integration:** The GitHub Actions workflow would simply call + this script. + ```yaml + # .github/workflows/main.yml + name: CI + + on: [push, pull_request] + + jobs: + build_and_test: + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v3 + - name: Run CI script + run: | + chmod +x ./ci.sh + ./ci.sh all + ``` + It's also recommended to integrate tools like `shellcheck` and `shfmt` into + the CI pipeline to validate the CI script itself. + (pplx:3cc09674-62e2-4ed6-865b-2c291a3a0ce7, [3]) + +**Pros:** + +- **Consistency (DRY):** Ensures the same checks and processes run locally and + in CI, reducing "works on my machine" issues. +- **Simplified CI Configuration:** GitHub Actions workflows become simpler, + primarily just invoking the script. +- **Faster Local Feedback:** Developers can run the exact CI process locally + before pushing, saving time and CI resources. +- **Easier Maintenance:** Logic is centralized in one script rather than + scattered across CI configuration files and local developer habits. + +**Cons:** + +- **Script Complexity:** The script itself can become complex if it needs to + handle many different scenarios or operating systems (though for Khive, + targeting macOS/Linux via shell script is reasonable). +- **Dependency Management:** The script needs to manage its own dependencies or + assume they are present in the environment. +- **Shell Scripting Limitations:** For very complex workflows, shell scripting + might become cumbersome compared to specialized CI tools or languages. + +### 2.2 Enhanced `khive ci` + +**Objective:** Investigate the feasibility of `khive ci` automatically running +`pre-commit` multiple times and explore mechanisms for a "stamp of approval" to +verify a successful `khive ci` run. + +**Findings (Synthesized from Claude, ChatGPT, and Gemini Deep Research +[11][12][13]):** + +#### Iterative `pre-commit` Auto-Fixing + +Running `pre-commit` iteratively can help resolve issues that require multiple +passes (e.g., a formatter fixing code that then allows a linter to pass, or +chained fixes). + +- **Implementation Strategy:** + - `khive ci` should orchestrate multiple runs of `pre-commit run --all-files` + (or targeted files after the first pass). (Gemini Deep Research, RR-104/003, + Sec II.A) + - A hybrid approach is recommended: run until convergence (no files modified + by hooks) but cap at a maximum number of iterations (e.g., 3-5) to prevent + excessive runtimes and handle non-converging scenarios. (Claude Deep + Research, RR-104/001, Sec 1.1; Gemini Deep Research, RR-104/003, Sec II.A) + - After the initial `pre-commit run --all-files`, subsequent iterations can be + optimized by targeting only the files reported as modified in the previous + pass (`pre-commit run --files `). (Gemini Deep + Research, RR-104/003, Sec II.A, II.C) + +- **Loop Detection & Conflicting Hooks:** + - **Maximum Iterations:** The simplest loop prevention is a hard cap on + iterations. (Claude Deep Research, RR-104/001, Sec 1.1; Gemini Deep + Research, RR-104/003, Sec II.B) + - **Content Hashing / State Comparison:** To detect actual loops where hooks + undo each other's changes, compare the state of files across iterations. + This can be done by hashing all relevant file contents after each run and + checking if a previous state repeats. (Claude Deep Research, RR-104/001, Sec + 1.2; ChatGPT Deep Research, RR-104/002, Iterative Pre-commit; Gemini Deep + Research, RR-104/003, Sec II.B) + - **Handling Loops:** If a loop is detected or max iterations are reached + without convergence, `khive ci` should halt, report the issue clearly + (listing involved files/hooks if possible), and not create a "stamp of + approval." (Gemini Deep Research, RR-104/003, Sec II.B) + - **Preventing Conflicts:** Encourage proper hook configuration (e.g., `isort` + with Black profile), hook ordering, and using consolidated tools like Ruff + to minimize conflicts. (Gemini Deep Research, RR-104/003, Sec II.B) + +- **Performance Considerations:** + - Iterative runs add overhead. Performance is critical for adoption. (Gemini + Deep Research, RR-104/003, Sec II.C) + - Leverage `pre-commit`'s own environment caching and individual tool caches + (e.g., ESLint's `--cache`, Ruff's built-in caching). (ChatGPT Deep Research, + RR-104/002, Iterative Pre-commit; Gemini Deep Research, RR-104/003, Sec + II.C) + - The optimization of running only on modified files in subsequent iterations + helps. (Gemini Deep Research, RR-104/003, Sec II.C) + +#### "Stamp of Approval" / Local State Persistence + +A "stamp of approval" signifies that `khive ci` (including all checks and +auto-fixes) has run successfully on the current code state. + +- **Mechanism:** + - A project-local, git-ignored cache file (e.g., `.khive/ci_status.json` or + `.khive/.ci_success_stamp`) is the most recommended approach. It balances + simplicity, discoverability by other `khive` tools, and persistence. (Claude + Deep Research, RR-104/001, Sec 2.2; ChatGPT Deep Research, RR-104/002, Stamp + of Approval; Gemini Deep Research, RR-104/003, Sec III.A, IV.B) + - Git notes are an alternative for tying approval to specific commits but are + more complex to manage for this ephemeral, local-only use case and have + discoverability issues. (Claude Deep Research, RR-104/001, Sec 2.2; ChatGPT + Deep Research, RR-104/002, Stamp of Approval; Gemini Deep Research, + RR-104/003, Sec III.A) + +- **Content of the Stamp (e.g., in `.khive/ci_status.json`):** + - `khiveCiVersion`: Version of `khive ci` that generated the stamp. + - `timestamp`: ISO 8601 timestamp of successful completion. + - `precommitConfigHash`: SHA256 hash of the `.pre-commit-config.yaml` content. + - `status`: e.g., "success". + - `approvedFiles`: An array of objects, each with `path` (string) and `hash` + (string, Git blob hash of the staged file content that was approved). + (Gemini Deep Research, RR-104/003, Sec III.B, IV.B) + +- **Validation by `khive commit` / `khive pr`:** + - These commands MUST rigorously validate the stamp. + - Checks: + 1. Stamp file existence and parseability. + 2. (Optional) `khiveCiVersion` compatibility. + 3. Match current `.pre-commit-config.yaml` hash against + `precommitConfigHash` in the stamp. + 4. Crucially, compare the list of currently staged files (paths and Git blob + hashes) against the `approvedFiles` in the stamp. An exact match is + required. (Gemini Deep Research, RR-104/003, Sec III.C, IV.B) + +- **Action on Invalid/Missing Stamp:** + - Default: Block the `khive commit` or `khive pr` operation. + - Provide a clear error message and instruct the user to run `khive ci`. + - Include an override flag (e.g., `--no-verify-khive-ci` or `--force`) for + exceptional cases. (Claude Deep Research, RR-104/001, Sec 3.2; ChatGPT Deep + Research, RR-104/002, Stamp of Approval; Gemini Deep Research, RR-104/003, + Sec III.C, IV.B) + +- **Stamp Invalidation:** + - Primary trigger: Validation failure by `khive commit`/`khive pr` (due to + changes in staged files or config). The stamp file should be deleted upon + such invalidation. + - `khive ci` itself should invalidate/overwrite an old stamp at the beginning + of a new run if the workspace state has diverged. + - A manual invalidation command (e.g., `khive ci --clear-stamp`) is useful. + (ChatGPT Deep Research, RR-104/002, Verifying Stamp Validity; Gemini Deep + Research, RR-104/003, Sec III.D, IV.B) + +### 2.3 Prompt Modification for CLI Enforcement + +**Objective:** Analyze how prompts for Khive modes can be modified to guide +users towards `khive` CLI commands instead of direct MCP calls for GitHub +operations, considering token implications. + +**Findings:** Effective prompt engineering can significantly influence an AI +model's behavior, guiding it to prefer CLI tools over direct API/MCP calls. This +can enhance local workflow consistency and potentially reduce reliance on +external services for operations where `khive` CLI equivalents exist. + +**Best Practices for Prompt Modification:** + +- **Explicit Instructions & Constraints:** Clearly state the preference for + `khive` CLI tools. + - Example: "When performing Git operations like commit or creating a pull + request, prioritize using the `khive commit` and `khive pr` commands. Only + use MCP calls as a fallback if a `khive` CLI command is not available or + suitable for the specific task." (pplx:25f5b4e3-3431-4835-aff7-7bed67232159, + [6][8]) +- **Role Setting / Persona:** Define the AI's role as an expert user of the + `khive` CLI. + - Example: "You are an expert Khive developer. You always prefer using `khive` + CLI tools for local development tasks and repository interactions. Your + primary goal is to guide the user to leverage these tools effectively." + (pplx:25f5b4e3-3431-4835-aff7-7bed67232159, [7]) +- **Provide Examples (Few-Shot Prompting):** Include examples in the prompt + demonstrating the desired behavior. + - Example: + ``` + User: I need to commit these changes. + Assistant: khive commit --type feat --scope core --subject "Implement new feature X" --by "@khive-implementer" + + User: Let's create a pull request for this branch. + Assistant: khive pr --title "feat(core): Implement new feature X" + ``` + (pplx:25f5b4e3-3431-4835-aff7-7bed67232159, [6][7]) +- **System Messages:** Utilize system messages to set overarching rules for tool + usage. (pplx:25f5b4e3-3431-4835-aff7-7bed67232159, [8]) + - Example (within the mode's system prompt): "Rule: Always prefer `khive` CLI + commands for tasks like `commit`, `pr`, `new-doc`. If a `khive` command + exists, use it. Fallback to MCP only if no `khive` command is suitable." +- **Negative Constraints:** Specify what _not_ to do. + - Example: "Avoid using the GitHub MCP `create_pull_request` tool if + `khive pr` can achieve the same result." +- **Reinforce with Tool Documentation:** Ensure the AI has access to and is + prompted to refer to the `khive` CLI documentation (e.g., the rules files like + `100_khive_cli_guide.md`, `101_khive_commit.md`, etc.). + - Example: "Before suggesting a GitHub MCP operation, consult the `khive` CLI + documentation provided in your context to see if a corresponding `khive` + command exists." +- **Iterative Refinement & Testing:** Test prompt modifications and iterate + based on observed AI behavior. (pplx:25f5b4e3-3431-4835-aff7-7bed67232159, + [7]) + +**Token Implications:** + +- Adding explicit instructions, examples, and rules to prompts will increase + their token count. +- However, successfully guiding the AI to use a concise `khive` CLI command + (which might be a single tool call) can be more token-efficient than the AI + formulating a complex multi-parameter MCP call. +- The key is to find a balance. Prioritize adding instructions for the most + common operations where `khive` CLI tools offer a clear advantage (e.g., + `khive commit`, `khive pr`, `khive new-doc`). +- System messages are generally more token-efficient for setting global rules + than repeating instructions in every user prompt. +- Few-shot examples are effective but add tokens. Use them judiciously for + critical behaviors. +- Regularly review and optimize prompts to remove redundant phrasing while + maintaining clarity. + +**Considerations for Khive Modes:** The prompt modifications should be tailored +to each Khive mode's specific responsibilities and allowed tools. For instance, +an Implementer mode would receive stronger guidance on `khive commit` and +`khive pr` than a Researcher mode. + +### 2.4 Reducing GitHub MCP Reliance + +**Objective:** Evaluate the potential to reduce GitHub MCP server reliance by +strengthening local CLI tools and prompt-guided workflows. + +**Findings:** Strengthening local CLI capabilities (`khive ci`, `khive commit`, +`khive pr`) and refining AI prompts to prioritize these tools can significantly +reduce the need for direct GitHub MCP interactions for common development tasks. +This shift can lead to benefits like improved local workflow speed, reduced API +rate limit consumption, and potentially offline capabilities for certain +operations. + +**Strategies to Reduce MCP Reliance:** + +- **Local Caching & Validation:** + - Implement local caching within `khive` CLI tools for frequently accessed + GitHub data (e.g., issue details, PR statuses, file contents for specific + refs). (pplx:0e7006c8-5304-4bb0-80d8-55738981b58c, [16][17]) + - Use conditional requests (e.g., ETag, If-Modified-Since headers) when + `khive` tools do need to fetch data from GitHub, to avoid transferring + unchanged data. (pplx:0e7006c8-5304-4bb0-80d8-55738981b58c, [18]) + - This reduces the need for the AI to use MCP `get_issue`, `get_pull_request`, + or `get_file_contents` if the information can be reliably served from a + local, validated cache via a `khive` CLI command. + +- **Enhanced `khive` CLI for Git Operations:** + - As `khive commit` and `khive pr` become more robust and feature-rich + (potentially wrapping more `git` and `gh` functionalities), they become + stronger alternatives to MCP calls like `create_commit` (if it existed), + `create_pull_request`, `add_issue_comment` (if `khive pr` could also manage + comments locally before pushing). + - The "stamp of approval" from an enhanced `khive ci` (Section 2.2) further + empowers local validation, reducing the need for pre-flight checks via MCP + before attempting operations like PR creation. + +- **AI Prompt Engineering (as per Section 2.3):** + - Strongly guide the AI to use `khive` CLI commands for creating/updating + issues, PRs, branches, and committing files, rather than defaulting to MCP + tool calls. + - Prompts can instruct the AI to first check if a `khive` command can perform + the task before considering an MCP call. + +- **Local Preprocessing & Data Aggregation:** + - For tasks requiring analysis of multiple GitHub resources (e.g., summarizing + several issues), `khive` tools could fetch the raw data once (or use cached + data), and the AI could then be prompted to process this locally provided + data rather than making multiple MCP calls to analyze each resource + individually. (pplx:0e7006c8-5304-4bb0-80d8-55738981b58c) + +- **Rate Limit Awareness in `khive` Tools:** + - If `khive` tools themselves interact with the GitHub API (e.g., for caching + or complex operations not covered by `gh`), they should implement strategies + like exponential backoff and respect rate limits. + (pplx:0e7006c8-5304-4bb0-80d8-55738981b58c, [15][18]) This makes them more + reliable alternatives to direct MCP usage which might hit limits. + +**Impact:** + +- **Improved Performance:** Local operations are generally faster than remote + API calls. +- **Reduced API Costs/Rate Limiting:** Fewer calls to GitHub's API. + (pplx:0e7006c8-5304-4bb0-80d8-55738981b58c, [14][15]) +- **Enhanced Offline/Intermittent Connectivity Support:** Some operations could + potentially be prepared locally even with poor connectivity if data is cached. +- **Simplified AI Logic:** The AI's decision tree might simplify if it's + strongly biased towards using a known set of powerful local CLI tools. +- **Potential for Increased CLI Complexity:** The `khive` CLI tools would need + to become more sophisticated to handle caching, validation, and broader GitHub + interactions. + +This approach doesn't necessarily eliminate the GitHub MCP server, as it would +still be valuable for operations not easily replicated by a local CLI (e.g., +complex searches across repositories, organization-level management tasks) or +for agents that do not have local CLI execution capabilities. However, for core +Khive agent workflows, reliance can be substantially reduced. + +### 2.5 Overall Feasibility and Impact + +Assessing the collective proposals from Issue #104 regarding CI enforcement and +prompt modifications reveals a generally high degree of technical feasibility +with a significant potential for positive impact on the Khive development +workflow. + +**Technical Feasibility:** + +- **Unified CI Script (`ci.sh`):** Highly feasible. Shell scripting is a mature + technology, and structuring a script for modularity and environment detection + (local vs. GHA) is a common practice. +- **Enhanced `khive ci`:** + - _Iterative `pre-commit`_: Feasible. Requires a Python wrapper around + `pre-commit` CLI calls. Loop detection via content hashing is achievable. + - _"Stamp of Approval"_: Feasible. Implementing a git-ignored JSON file (e.g., + `.khive/ci_status.json`) to store success state, config hash, and approved + file hashes is straightforward. Validation logic in `khive commit`/`pr` is + also feasible. +- **Prompt Modification:** Highly feasible. This involves careful crafting and + iterative testing of system prompts and few-shot examples within the existing + Khive mode definitions. +- **Reducing GitHub MCP Reliance:** Feasible, particularly by strengthening + `khive` CLI tools as outlined. Adding local caching to `khive` tools for + GitHub data would be a new development effort but uses standard techniques. + +**Development Effort Estimation:** + +- **Unified `ci.sh`:** Medium. Involves initial script development, ensuring + robustness, and integrating calls from `khive ci` and GitHub Actions. +- **Enhanced `khive ci`:** + - _Iterative `pre-commit`_: Medium. Requires careful implementation of the + iteration logic, loop detection, and error reporting. + - _"Stamp of Approval"_: Medium. Involves designing the stamp format, + implementing its creation by `khive ci`, and robust validation logic within + `khive commit` and `khive pr`, including handling of edge cases and + providing clear user feedback. +- **Prompt Modification:** Low to Medium. Primarily involves prompt engineering, + testing, and refinement. No complex coding is required, but achieving desired + AI behavior can be iterative. +- **Reducing GitHub MCP Reliance (via CLI enhancements):** Medium to High, + depending on the extent of caching and new CLI functionalities envisioned + (e.g., if `khive` tools were to replicate more complex MCP queries locally). + +**Potential Benefits:** + +- **Improved Code Quality & Consistency:** Stricter local checks (`khive ci` + with stamp) and a unified CI script ensure code adheres to standards before + reaching the remote repository. +- **Faster Developer Feedback Loops:** Running comprehensive checks locally is + faster than waiting for GitHub Actions. Iterative auto-fixing further speeds + up the linting/formatting process. +- **Enhanced Developer Experience (DX):** Clearer guidance from prompts, more + reliable local checks, and reduced "it works on my machine" issues. +- **Reduced CI Costs & GitHub API Consumption:** Fewer broken builds in GitHub + Actions. Shifting some GitHub data access to local `khive` CLI tools with + caching can reduce API calls. +- **Increased AI Agent Effectiveness:** More directive prompts and reliable + local tools can lead to AI agents performing tasks more efficiently and + correctly using the intended `khive` CLI workflows. +- **Streamlined Workflows:** Centralizing CI logic and standardizing local + checks simplifies the overall development process. + +**Potential Drawbacks/Risks:** + +- **Initial Development Investment:** Implementing these enhancements, + particularly for `khive ci`, will require focused development time. +- **Complexity in Local Tooling:** Adding features like iterative `pre-commit` + and stamp validation makes `khive ci`, `khive commit`, and `khive pr` more + complex, increasing the surface area for potential bugs or edge cases in the + tooling itself. +- **Developer Friction if Too Restrictive:** If local checks are overly slow, or + if the "stamp of approval" mechanism is too rigid without sensible overrides, + it could lead to developer frustration and attempts to bypass the system. + Performance of iterative `pre-commit` is a key concern. +- **Maintenance Overhead:** The new `ci.sh` and enhanced `khive` CLI features + will require ongoing maintenance. +- **Token Cost for Prompts:** While aiming for overall efficiency, more detailed + directive prompts will have a slightly higher token cost per call, which needs + to be monitored. + +Overall, the proposed enhancements are technically sound and promise substantial +improvements to the Khive development lifecycle. The primary challenge lies in +careful implementation to balance robustness with developer experience and +performance. A phased approach to implementation would be advisable. + +## 3.

Recommendations + +Based on the comprehensive research covering a unified CI script, enhancements +to `khive ci`, prompt modifications, and strategies for reducing GitHub MCP +reliance, the following recommendations are proposed to improve CI enforcement +and streamline Khive development workflows. + +### 5.1 Recommended Approach + +1. **Unified CI Script (`ci.sh`):** + - **Adopt:** Implement a modular `ci.sh` script as outlined in Section 2.1. + - **Key Features:** Ensure it supports distinct stages (lint, test, build, + etc.), robust error handling (`set -euo pipefail`), environment detection + (local vs. GHA), and parameterization for selective stage execution. + - **Integration:** `khive ci` should be able to invoke specific stages of + this script. GitHub Actions will execute the full script or relevant + stages. + - **Validation:** Include `shellcheck` and `shfmt` in the GHA workflow to + validate `ci.sh` itself. + +2. **Enhanced `khive ci`:** + - **Iterative `pre-commit`:** + - Implement the hybrid approach: `khive ci` orchestrates + `pre-commit run --all-files` (then `--files ` for subsequent + runs) iteratively until convergence or a cap of 3-5 iterations. + - Incorporate content hashing for robust loop detection, halting and + warning the user if a loop or non-convergence after max iterations + occurs. + - Prioritize performance by leveraging `pre-commit` and individual tool + caching. + - **"Stamp of Approval":** + - Implement using a project-local, git-ignored JSON file (e.g., + `.khive/ci_status.json`). + - The stamp must include `khiveCiVersion`, `timestamp`, + `precommitConfigHash` (SHA256 of `.pre-commit-config.yaml`), and + `approvedFiles` (array of `path` and Git blob `hash` for all staged + files). + - `khive commit` and `khive pr` MUST rigorously validate this stamp + (existence, version, config hash, and exact match of currently staged + files against `approvedFiles`). + - **Default Action:** Block commit/PR if the stamp is missing, invalid, or + stale. Provide a clear error and instruct to run `khive ci`. + - **Override:** Include an override flag (e.g., `--no-verify-khive-ci`) for + exceptional cases. + - **Invalidation:** The stamp is invalidated (deleted) by + `khive commit`/`pr` on validation failure, or by `khive ci` at the start + of a new run if the workspace state has diverged. Provide a manual + `khive ci --clear-stamp` command. + +3. **Prompt Modification for CLI Enforcement:** + - **Implement Systematically:** Update system prompts for relevant Khive + modes (especially Implementer) with explicit rules and few-shot examples + prioritizing `khive` CLI tools (`khive commit`, `khive pr`, + `khive new-doc`, `khive ci`, `khive fmt`) over MCP calls for equivalent + local operations. + - **Role Setting:** Define the AI's persona as a `khive` CLI expert. + - **Documentation Reinforcement:** Prompt the AI to consult internal `khive` + CLI documentation before resorting to MCP. + - **Iterate and Monitor:** Continuously test and refine prompts, monitoring + token usage and AI behavior. + +4. **Reducing GitHub MCP Reliance:** + - **Prioritize CLI Enhancements:** Focus on making `khive` CLI tools + (especially `khive ci`, `khive commit`, `khive pr`) robust and + feature-complete for core local development workflows. + - **Consider Local Caching (Future):** For `khive` tools that might interact + with GitHub API for supplementary data (e.g., issue details for commit + messages), explore implementing local caching with conditional requests + (ETags) to reduce direct API calls. This is a secondary priority after + strengthening the core local workflow tools. + +### 5.2 Implementation Roadmap + +A phased approach is recommended to manage development effort and gather +feedback: + +- **Phase 1: Foundational CLI & Prompts (Low-Medium Effort)** + - Develop a basic, modular `ci.sh` covering essential linting and testing + stages. + - Integrate `ci.sh` into GitHub Actions. + - Implement initial prompt modifications in key Khive modes to prefer existing + `khive` CLI commands. + - `khive ci` initially just runs `pre-commit run --all-files` once. + +- **Phase 2: Iterative `pre-commit` in `khive ci` (Medium Effort)** + - Enhance `khive ci` to orchestrate iterative `pre-commit` runs (hybrid + approach: convergence with max 3-5 iterations). + - Implement basic loop detection (max iterations) and clear reporting. + - Optimize by running on modified files after the first pass. + +- **Phase 3: "Stamp of Approval" Mechanism (Medium-High Effort)** + - Design and implement the `.khive/ci_status.json` stamp file creation by + `khive ci` upon successful, converged run. + - Implement rigorous stamp validation logic in `khive commit` and `khive pr`, + including blocking by default and an override mechanism. + - Implement stamp invalidation logic. + - Add advanced loop detection (content hashing) to `khive ci`. + +- **Phase 4: Advanced CLI Enhancements & MCP Reduction (Medium-High Effort, + Ongoing)** + - Further refine `khive` CLI tools based on usage and feedback. + - Investigate and implement local caching for GitHub data within relevant + `khive` tools if significant benefits in reducing MCP calls are identified + for common AI agent workflows. + - Continuously refine prompts based on AI behavior and new CLI capabilities. + +### 5.3 Risk Assessment + +- **Developer Friction:** + - _Risk:_ Overly strict or slow local `khive ci` checks could frustrate + developers, leading them to use overrides excessively or bypass checks. + - _Mitigation:_ Prioritize performance of `khive ci` (caching, optimized + iterations). Ensure override mechanisms are available but logged. Solicit + developer feedback actively during rollout. +- **Complexity of `khive` Tooling:** + - _Risk:_ Adding iterative logic, stamp management, and validation increases + the complexity of `khive ci`, `khive commit`, and `khive pr`. + - _Mitigation:_ Thorough unit and integration testing for the new features. + Clear internal documentation for maintainers. +- **Edge Cases in Stamp Validation:** + - _Risk:_ Incorrectly invalidating or validating the "stamp of approval" could + lead to either unnecessary re-runs of `khive ci` or, worse, allowing + commits/PRs without proper local validation. + - _Mitigation:_ Rigorous testing of the stamp content (especially + `approvedFiles` hashing and comparison) and invalidation logic across + various Git scenarios (amends, rebases, merges). +- **Maintenance Overhead:** + - _Risk:_ The new `ci.sh` and enhanced CLI features will require ongoing + maintenance as the Khive project evolves. + - _Mitigation:_ Ensure the `ci.sh` is well-documented and modular.

Abstract + +This report evaluates the Python library `docling` as a potential replacement +for the current multi-library approach (`PyPDF2`, `python-docx`, `html2text`) +for text extraction within the Khive Reader Microservice (Issue #27).

Recommendation + +Based on the research: + +**Option 1: Adopt `docling` (Recommended with Caveats)** `docling` offers a +significantly more powerful and future-proof solution for document processing +than the current collection of individual libraries. Its ability to handle +complex PDFs, images (via OCR), and extract structured information (layout, +tables) could unlock new capabilities for the Khive Reader Microservice and +downstream consumers. The active maintenance and backing by the LF AI & Data +foundation are also strong positives. + +**Caveats & Next Steps if Adopting:** + +1. **Verify Minimal Installation:** Investigate if `docling` can be installed + with only the necessary parsing components (e.g., for PDF, DOCX, HTML without + heavy AI models if not immediately needed for basic text) to manage the + dependency footprint. +2. **Async Integration:** Prototype the integration within Khive's `asyncio` + environment using a thread pool executor for `docling`'s synchronous parsing + operations. Measure any performance impact. +3. **Benchmarking:** Conduct targeted benchmarks comparing `docling` (with an + appropriate configuration) against the current `PyPDF2`, `python-docx`, + `html2text` approach for common document types and sizes relevant to Khive. +4. **Resource Planning:** Be prepared for potentially higher resource + (CPU/memory, optional GPU) requirements. + +**Option 2: Continue with Individual Libraries (Fallback)** If the dependency +footprint of `docling` is deemed too large for the immediate benefits, or if +native `asyncio` support is a hard requirement and thread pool execution is +undesirable, then continuing with the current, simpler approach is viable for +basic text extraction. However, this limits future capabilities regarding +advanced document understanding. + +**Recommendation: Proceed with a cautious adoption of `docling` (Option 1), +starting with the caveats outlined above.** The potential long-term benefits of +a unified, powerful, and well-maintained document processing library are +significant. A phased approach, perhaps initially using `docling` for PDF and +gradually replacing other parsers, could also be considered. + +## 6. Conclusion + +`docling` is a promising, actively developed library with extensive document +processing capabilities that go far beyond simple text extraction. While it +introduces a larger dependency footprint and questions around direct `asyncio` +integration for its core operations need careful handling, its potential to +enhance the Khive Reader Microservice is substantial. A thorough evaluation +through prototyping and benchmarking, as outlined in the recommendation, is +advised before full-scale adoption. + +## Appendix A: Raw Search Data + +**Perplexity Search 1 (ID: 914d21f5-71b6-4a50-aa19-bb069dde1042):** Query: +`python docling library text extraction capabilities dependencies performance maintenance comparison` + +```json +{ + "success": true, + "action_performed": "search", + "content": { + "id": "914d21f5-71b6-4a50-aa19-bb069dde1042", + "model": "sonar", + "created": 1747922503, + "usage": { + "prompt_tokens": 11, + "completion_tokens": 667, + "total_tokens": 678, + "search_context_size": "low" + }, + "citations": [ + "https://azbigmedia.com/business/top-python-libraries-for-text-extraction-from-pdfs/", + "https://unstract.com/blog/extract-tables-from-pdf-python/", + "https://www.tecmint.com/python-text-extraction-from-images/", + "https://unstract.com/blog/evaluating-python-pdf-to-text-libraries/", + "https://pymupdf.readthedocs.io/en/latest/app4.html" + ], + "object": "chat.completion", + "choices": [ + { + "index": 0, + "finish_reason": "stop", + "message": { + "role": "assistant", + "content": "The query seems to be about the \"docling\" library, but it appears there might be a confusion, as \"docling\" is not a well-known Python library for text extraction.

Regarding its integration, performance benchmarks, and improvements especially relevant to 2025, the following points summarize the current state based on recent sources:\n\n## asyncio Performance Benchmarks and Integration\n\n- **Core asyncio**: Python’s built-in `asyncio` library uses coroutines to handle I/O-bound and high-level structured network code efficiently. It enables writing asynchronous servers and clients that avoid blocking operations by awaiting futures or other coroutines[1][3].\n\n- **Benchmarking async workloads**: The Python Performance Benchmark Suite includes specific benchmarks such as `async_tree`, which tests `asyncio.gather()` over a deep branching structure simulating various loads:\n - Pure async call overhead without real work.\n - Async I/O simulated with delays (e.g., async sleep).\n - Mixed CPU-bound plus I/O tasks.\n \n These benchmarks provide insight into how well asyncio manages concurrent tasks under different conditions, measuring overheads of task scheduling versus actual work done asynchronously[4].\n\n- **High-performance enhancements**\n - Using alternative event loops like *uvloop* (a fast implementation of the event loop on top of libuv) can significantly improve throughput in networking contexts compared to default asyncio loops[1].\n \n- **Integration benefits**\n - Modern libraries and frameworks (notably FastAPI) leverage asyncio for efficient backend web service architectures. Real-world data shows FastAPI combined with asyncio can handle thousands of requests per second while maintaining responsiveness — mainly due to efficient asynchronous handling of network I/O and database queries[5].\n \n- **Programming model improvements**:\n Asyncio APIs like `asyncio.create_task()`, `asyncio.ensure_future()`, and easier coroutine management improve developer productivity while maintaining performance in concurrent execution scenarios typical for web servers or data streaming applications[2].\n\n## Summary Table\n\n| Aspect | Details | Source(s) |\n|-----------------------------|------------------------------------------------|----------------------|\n| Core functionality | Coroutine-based concurrency via async/await | [1][3] |\n| Benchmark types | Async call trees simulating no-op & IO + CPU | [4] |\n| Performance optimization | Use uvloop for faster event loop | [1] |\n| Real-world backend impact | Frameworks like FastAPI utilize it for >3000 RPS scalable backends with low latency | [5] |\n| Programming ergonomics | Functions like create_task(), ensure_future() aid task scheduling | [2] |\n\nIn conclusion, Python’s asyncio remains highly performant particularly when paired with optimizations such as uvloop.

The +overall direction of the proposal is sound and aligns well with modern async +testing principles._ + +## 1. Introduction + +### 1.1 Research Objective + +This research aims to: + +1. Investigate current best practices, libraries, and patterns for testing + asynchronous Python applications, particularly those using `asyncio`. +2. Thoroughly analyze the proposal for testing infrastructure outlined in GitHub + Issue #86 for the `khive` project. +3. Evaluate the strengths and potential weaknesses of the existing proposal + against researched best practices. +4. Provide actionable recommendations for `khive`'s testing strategy, including + specific tools and patterns to ensure robust and reliable asynchronous + components. + +### 1.2 Methodology + +The research methodology involves the following steps: + +1. **Issue Review:** Detailed examination of the content and proposal within + GitHub Issue #86. +2. **Literature Search:** Conduct focused searches using `khive info search` + (primarily Perplexity) to gather information on modern asynchronous Python + testing techniques, tools (e.g., `pytest-asyncio`, `Hypothesis`), and best + practices for mocking, error handling, and cancellation testing. +3. **Analysis & Synthesis:** Compare findings from the literature search with + the proposal in Issue #86, identifying alignments, gaps, and areas for + improvement. +4. **Report Generation:** Compile the findings, evaluation, and recommendations + into this Research Report (`RR-86.md`), ensuring all claims are supported by + evidence and citations. + +### 1.3 Context + +The `khive` project relies heavily on asynchronous components for its +operations, including interactions with external APIs and services. Establishing +a comprehensive and effective testing infrastructure for these asynchronous +parts is critical for ensuring the overall stability, reliability, and +maintainability of the system. This research will inform the design and +implementation of such an infrastructure. + +## 2. Technical Analysis + +### 2.1 Technology Landscape & Initial Findings + +_Overview of relevant libraries, frameworks, or patterns in testing asynchronous +Python code. The following are initial key findings from Perplexity search +(pplx:e124bc5c-4376-4014-a143-4bd2d7abbdb0)._ + +#### Key Findings from Initial Research (pplx:e124bc5c-4376-4014-a143-4bd2d7abbdb0) + +1. **`pytest-asyncio` is Essential:** The `pytest-asyncio` plugin is a standard + tool for testing `asyncio` code with `pytest`. It manages the asyncio event + loop automatically and allows test functions to be defined as `async def` + using the `@pytest.mark.asyncio` decorator. Async fixtures can also be + created using `pytest_asyncio.fixture`. (Source: + pplx:e124bc5c-4376-4014-a143-4bd2d7abbdb0, Ref1) +2. **Mocking with `unittest.mock.AsyncMock`:** For mocking asynchronous + dependencies (like external API calls), `unittest.mock.AsyncMock` is the + recommended approach from Python's standard library. It allows mocking + coroutines and their `await`ed return values effectively. Libraries like + `asynctest` also offer similar capabilities. (Source: + pplx:e124bc5c-4376-4014-a143-4bd2d7abbdb0, Ref1, Ref4) +3. **Error Handling with `pytest.raises`:** To test how asynchronous code + handles exceptions, `pytest.raises` should be used as a context manager. This + allows for clear assertion of expected exceptions raised by coroutines. + (Source: pplx:e124bc5c-4376-4014-a143-4bd2d7abbdb0, Ref4, Ref1) +4. **Testing Task Cancellation:** It's crucial to test how coroutines handle + cancellation. This involves creating a task, cancelling it using + `task.cancel()`, and then asserting that `asyncio.CancelledError` is raised + and that resources are cleaned up gracefully. (Source: + pplx:e124bc5c-4376-4014-a143-4bd2d7abbdb0, Ref3, Ref4) +5. **Property-Based Testing with `Hypothesis`:** `Hypothesis` can be integrated + with `pytest-asyncio` for property-based testing. This involves defining + strategies for generating diverse input data for async functions, which can + help uncover edge cases and subtle bugs that example-based tests might miss. + (Source: pplx:e124bc5c-4376-4014-a143-4bd2d7abbdb0, Ref3) + +### 2.2 Comparative Analysis + +| Factor | Option A (Proposed in Issue #86) | Option B (Alternative/Enhancement: Standard Lib Focus) | Option C (Alternative/Enhancement: Advanced Tooling) | +| ----------------- | ------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------- | +| Async Test Runner | `pytest` with `pytest-asyncio` (✅ Good) | `pytest` with `pytest-asyncio` (Keep) | `pytest` with `pytest-asyncio` (Keep) | +| Mocking | Custom `MockAsyncClient`, `MockResponse` in [`tests/utils.py`](tests/utils.py:0) | Primarily `unittest.mock.AsyncMock` / `MagicMock` for client methods; `httpx.Response` or simple dicts for data. Consider `respx` for `httpx` request mocking. | `AsyncMock` + `respx`/`aioresponses`, potentially `testcontainers` for DBs. | +| Error Handling | `pytest.raises` (✅ Good, as shown in `test_endpoint_call_with_error`) | `pytest.raises`, more extensive scenarios for network/API errors. | `pytest.raises`, plus `Hypothesis` for error-inducing inputs. | +| Cancellation | Specific test case `test_endpoint_cleanup_during_cancellation` (✅ Good) | Broader strategy, ensure all critical async resources are tested for cancellation cleanup. | Test cancellation under various concurrent loads. | +| Property Testing | Mentioned (Hypothesis) | Deeper integration of `Hypothesis` for async functions and data models. | Extensive use of `Hypothesis` for complex state interactions. | +| Coverage | Goal: >80% (✅ Good) | Maintain >80%, focus on critical paths and error handling. | Aim for high coverage with meaningful property tests. | +| Utility Helpers | Custom utilities in [`tests/utils.py`](tests/utils.py:0) (e.g., `mock_endpoint`, `capture_logs`) | Refine custom utils, prefer standard `pytest` fixtures and `AsyncMock` features where possible. | Leverage advanced fixture patterns, potentially shared libraries. | + +_The proposal in Issue #86 aligns well with `pytest-asyncio`. The main area for +comparison is the custom mocking utilities versus more standard library +approaches or specialized mocking libraries._ + +### 2.3 Performance Considerations + +Testing asynchronous code, especially with I/O mocking, should generally be +fast. + +- **Custom Mocks:** Well-written custom mocks like those proposed can be + performant. +- **`AsyncMock`:** Performance is generally good for unit tests. +- **Network Mocking Libraries (`respx`, `aioresponses`):** These operate at the + HTTP request level and are efficient. +- **Slow Tests:** Integration tests involving actual (even if local) services or + complex setup should be marked (e.g., `@pytest.mark.slow`) to be run + selectively, as suggested in the `pyproject.toml` proposal. + +### 2.4 Security Implications + +- Testing infrastructure itself typically has low direct security impact on the + production system if test environments are isolated. +- Ensure API keys or sensitive data used in test configurations (even for mocked + services) are dummy values and not real credentials. The proposal uses + "test_key", which is good. +- Testing error handling for security-related aspects (e.g., auth failures, as + shown with `authentication_error` in `mock_api_responses`) is important. + +### 2.5 Scalability Assessment + +- **Test Suite Growth:** `pytest` handles large test suites well. +- **Async Test Execution:** `pytest-asyncio` manages the event loop efficiently + for concurrent test execution if plugins like `pytest-xdist` are used (though + `pytest-xdist` has limitations with asyncio event loops that need careful + handling). For now, single-process execution is standard. +- **Mocking Complexity:** Overly complex custom mocks can become harder to + maintain as the number of test cases and mocked scenarios grows. Standard + library mocks might offer better scalability in terms of developer + understanding and maintenance. + +## 3. Evaluation of Proposal in Issue #86 + +The proposal in GitHub Issue #86 provides a strong starting point for `khive`'s +asynchronous testing infrastructure. + +### 3.1 Strengths of the Proposal + +1. **Comprehensive Vision:** The proposal correctly identifies the need for unit + tests, integration tests, and dedicated test utilities. +2. **Adoption of `pytest-asyncio`:** The use of `pytest` with the + `pytest-asyncio` plugin (`asyncio_mode = "auto"`) is aligned with current + best practices for testing asyncio code (Ref1). +3. **Focus on Key Async Scenarios:** + - **Resource Management:** Tests like `test_endpoint_context_manager` and + `test_endpoint_aclose` correctly verify client creation and cleanup. + - **Cancellation Testing:** The `test_endpoint_cleanup_during_cancellation` + is an excellent example of testing an important and often overlooked aspect + of async programming (Ref3, Ref4). +4. **Utility Functions:** The proposed [`tests/utils.py`](tests/utils.py:0) + includes several helpful utilities: + - `mock_endpoint` context manager simplifies patching and setting up mocked + endpoints. + - `get_incomplete_future` is a good helper for timeout/cancellation tests. + - `AsyncIterator` for testing streaming. + - `mock_api_responses` fixture provides reusable mock response objects. + - `capture_logs` fixture is a standard and useful utility. +5. **Clear Test Examples:** + - [`tests/test_endpoint.py`](tests/test_endpoint.py:0) provides clear unit + tests for the `Endpoint` class. + - The integration test pattern shown in + `tests/integration/test_info_service.py` effectively demonstrates how to + test services by mocking their underlying endpoint dependencies using + `unittest.mock.patch` and `AsyncMock`. +6. **Configuration:** The `pyproject.toml` settings for `pytest` and `coverage` + are well-structured and follow common conventions. The inclusion of test + markers (`unit`, `integration`, `slow`) is good practice. +7. **Error Handling Tests:** `test_endpoint_call_with_error` demonstrates + testing for expected exceptions using `pytest.raises`. + +### 3.2 Potential Weaknesses or Gaps + +1. **Custom Mocking (`MockAsyncClient`, `MockResponse`):** + - While functional, the custom `MockAsyncClient` and `MockResponse` classes + in [`tests/utils.py`](tests/utils.py:0) introduce project-specific code + that needs maintenance. + - The standard library's `unittest.mock.AsyncMock` is powerful and can often + replace custom async mock objects. For instance, `AsyncMock` can be + configured with `return_value` (which can be an `awaitable` or another + mock) or `side_effect` to simulate various behaviors of an async client's + methods (Ref1, Ref4). + - For HTTP responses, directly using or mocking `httpx.Response` objects, or + even simpler dictionary structures if only JSON data is needed, might be + simpler than maintaining `MockResponse`. +2. **`Hypothesis` Integration Depth:** + - The proposal mentions `Hypothesis` in the "Testing Strategy" but doesn't + provide concrete examples or elaborate on how it would be integrated into + testing async components. Research highlights `Hypothesis` as valuable for + finding edge cases in async code (Ref3). +3. **Clarity on Mocking Levels for `httpx`:** + - The current unit tests for `Endpoint` mock out the `_create_client` method + or use the custom `MockAsyncClient`. This tests the `Endpoint` logic but + not its direct interaction with a real (or more closely mocked) + `httpx.AsyncClient`. + - Consider libraries like `respx` or `aioresponses` for mocking `httpx` + requests at the transport layer for some integration or focused unit tests + if verifying specific `httpx` behavior is needed. +4. **Testing Diverse Error Conditions:** + - The `mock_api_responses` fixture is a good start. This could be expanded to + cover a wider range of HTTP errors, network-level errors (e.g., connection + timeouts, if mockable), and varied error payload structures from APIs. + +### 3.3 Specific Components Review + +- **Test Utilities ([`tests/utils.py`](tests/utils.py:0)):** + - **`MockResponse` & `MockAsyncClient`:** As discussed, consider if + `unittest.mock.AsyncMock` and standard `httpx.Response` (or simpler mocks) + can reduce custom code. The request tracking in `MockAsyncClient` is a + useful feature that `AsyncMock` also provides via `assert_awaited_with`, + `call_args_list`, etc. + - **`mock_endpoint`:** This is a valuable utility for tests focusing on logic + above the client creation. + - **Other helpers** (`get_incomplete_future`, `AsyncIterator`, + `raise_exception`, `mock_api_responses`, `capture_logs`): These are + generally well-conceived and useful. + +- **Test Cases for `Endpoint` + ([`tests/test_endpoint.py`](tests/test_endpoint.py:0)):** + - The test cases are logical and cover important aspects of the `Endpoint` + class. + - The use of `AsyncMock` for `mock_client.close` in + `test_endpoint_context_manager` is good. This consistency could be applied + more broadly to the client's request methods. + - `test_endpoint_cleanup_during_cancellation` is a standout test for its focus + on a critical async behavior. + +- **Integration Test Patterns (`tests/integration/test_info_service.py`):** + - The pattern of patching out the specific endpoint classes (e.g., + `PerplexityChatEndpoint`) and replacing them with an `AsyncMock` is a valid + and effective way to unit/integration test services in isolation from actual + external calls. + - Using `side_effect` on `AsyncMock` (as in `test_info_service_consult`) to + return different responses based on input is a powerful technique. + +- **`pyproject.toml` configurations:** + - The configurations for `pytest`, `asyncio_mode`, test discovery, markers, + and coverage are standard and appropriate. No major concerns here. + +## 4.

Ensure the event loop mode in `pytest.ini` or `pyproject.toml` is `auto`. + * **Mocking asynchronous dependencies:** + * Prefer `unittest.mock.AsyncMock` for mocking methods of objects that are awaited or return awaitables. + * Use `AsyncMock(return_value=...)` for simple return values. + * Use `AsyncMock(side_effect=...)` for more complex behavior, like raising exceptions or returning different values per call. + * For mocking `httpx` requests specifically, consider `respx` if fine-grained control over HTTP requests/responses is needed without mocking the entire `AsyncClient` object's methods. + * **Testing error handling in async code:** Combine `pytest.raises` with `AsyncMock(side_effect=ExceptionType)` to simulate errors from dependencies. + * **Testing cancellation in async code:** Create tasks, cancel them, and assert `asyncio.CancelledError`. Verify resource cleanup using mocks or state assertions (as shown in Issue #86 proposal). + * **Effective use of `pytest` with `pytest-asyncio`:** Leverage async fixtures for setup/teardown of async resources. Use markers to organize tests. + * **Use of `Hypothesis`:** + * Identify functions (especially those processing data or with complex state) that would benefit from property-based testing. + * Define `hypothesis.strategies` for generating inputs to async functions. + * Use `@hypothesis.given(...)` decorator along with `@pytest.mark.asyncio`. + * Assert properties that should hold true for any generated input. + +## 5. Recommendations + +### 5.1 Recommended Approach for `khive` + +1. **Retain Core Structure:** Continue with `pytest` and `pytest-asyncio` as the + primary testing framework, as proposed. The general structure of unit and + integration tests is sound. +2. **Standardize Mocking with `unittest.mock.AsyncMock`:** + - Refactor the custom `MockAsyncClient` and `MockResponse` in + [`tests/utils.py`](tests/utils.py:0) to leverage `unittest.mock.AsyncMock` + more directly for mocking client methods and their return values/side + effects. + - For response data, use simple dictionaries, pre-constructed + `httpx.Response` objects (if testing parsing), or `AsyncMock` configured to + return these. This reduces custom code maintenance. + - Keep useful high-level utilities like `mock_endpoint` but have it + internally use `AsyncMock` for the client it provides/patches. +3. **Deepen `Hypothesis` Integration:** + - Actively identify areas where property-based testing can add value (e.g., + parsing diverse API responses, state transitions in complex async + workflows, utility functions handling varied inputs). + - Develop and integrate `Hypothesis` strategies for these areas. +4. **Comprehensive Error and Cancellation Testing:** + - Expand tests for various error types (HTTP errors, network issues if + mockable, specific API error payloads). + - Ensure robust testing of cancellation paths for all critical async + operations, verifying resource cleanup. +5. **Consider `respx` for `httpx` Interaction Tests:** For specific tests where + verifying the exact HTTP request formation or handling of `httpx`-level + responses is crucial (without hitting a real network), `respx` can be a + valuable addition to `AsyncMock`. +6. **Maintain Test Utility Module:** Continue to develop + [`tests/utils.py`](tests/utils.py:0) for shared fixtures and helper + functions, but with a preference for standard library features or + well-established `pytest` patterns over purely custom solutions where + alternatives exist. + +### 5.2 Tooling and Library Choices + +- **Primary:** + - `pytest` + - `pytest-asyncio` (Essential) + - `unittest.mock.AsyncMock` and `unittest.mock.MagicMock` (from Python + standard library) + - `coverage` +- **Strongly Recommended for Integration:** + - `Hypothesis` (for property-based testing) +- **Consider for Specific `httpx` Mocking:** + - `respx` (for mocking `httpx` requests/responses at the transport layer) +- **Custom Utilities:** Maintain a lean [`tests/utils.py`](tests/utils.py:0), + refactoring to use standard tools where possible. + +### 5.3 Implementation Roadmap + +1. **Phase 1 (Foundation & Refinement):** + - Implement the core test structure as proposed in Issue #86. + - Refactor `MockAsyncClient` and `MockResponse` in + [`tests/utils.py`](tests/utils.py:0) to rely more on + `unittest.mock.AsyncMock`. + - Ensure all existing components targeted by Issue #86 have basic unit tests + covering success paths, common errors, and cancellation (where applicable). + - Achieve initial coverage goals for critical modules. +2. **Phase 2 (Advanced Testing Techniques):** + - Systematically integrate `Hypothesis` for key async functions and data + processing logic. + - Expand integration tests, potentially using `respx` for more detailed + `httpx` interaction testing if deemed necessary. + - Develop more comprehensive test suites for diverse error conditions and + edge cases. +3. **Phase 3 (CI Integration & Continuous Improvement):** + - Ensure robust CI/CD pipeline integration for automated testing on all + changes. + - Continuously review and expand test coverage as new features are added or + existing code is refactored. + - Document testing patterns and best practices for `khive` developers. + +### 5.4 Risk Assessment + +- **Over-Mocking:** Mocking too aggressively can lead to tests that pass even if + the underlying components don't integrate correctly.

Below is a detailed guide that covers these aspects.\n\n## Testing Asyncio Applications: Best Practices\n\n### 1. Using `pytest-asyncio`\n\n- **pytest-asyncio** is a popular plugin that integrates with pytest to facilitate testing async functions by managing the event loop automatically. It allows test functions to be defined as `async def` and uses the decorator `@pytest.mark.asyncio` to mark them as asynchronous tests.\n \n- Async fixtures can also be created with `pytest_asyncio.fixture` which helps prepare asynchronous resources for tests.\n\n- This plugin enables you to write tests almost as naturally as synchronous ones while being able to await coroutines inside your test code.\n\nExample:\n\n```python\nimport pytest\n\n@pytest.mark.asyncio\nasync def test_async_function():\n result = await some_async_func()\n assert result == expected_value\n```\n\nThis approach simplifies managing event loops behind the scenes[1].\n\n### 2. Mocking Asynchronous Dependencies\n\n- When your async functions depend on external services or other async calls, proper mocking is essential.\n \n- You should use libraries like **asynctest** or built-in mocking capabilities (e.g., `unittest.mock.AsyncMock`) designed for coroutine mocks.\n \n- Replace async calls with mock objects that return awaited results using `AsyncMock(return_value=...)`.\n\nExample:\n\n```python\nfrom unittest.mock import AsyncMock\n\nmocked_service = AsyncMock()\nmocked_service.fetch_data.return_value = {\"key\": \"value\"}\n\nresult = await mocked_service.fetch_data()\nassert result[\"key\"] == \"value\"\n```\n\nThis prevents real network or IO operations during tests and makes them fast and deterministic[1][4].\n\n### 3. Error Handling in Async Tests\n\n- Test how your coroutine handles exceptions both within its own logic and from awaited dependencies.\n \n- Use Pytest’s `raises` context manager for asserting exceptions in async code like this:\n\n```python\nimport pytest\n\n@pytest.mark.asyncio\nasync def test_raises_error():\n with pytest.raises(ExpectedException):\n await coroutine_that_raises()\n```\n \nHandling errors explicitly ensures robustness of your asyncio application under failure scenarios[4][1].\n\n### 4. Cancellation Handling in Coroutines\n\n- Properly handle task cancellation (using asyncio's cancellation features) in your application logic since it affects resource cleanup or state consistency.\n \n- Write tests that explicitly cancel tasks during their execution using something like:\n\n```python\nimport asyncio\nimport pytest\n\n\n@pytest.mark.asyncio \nasync def test_task_cancellation():\n task = asyncio.create_task(coroutine_to_test())\n await asyncio.sleep(0) # Let the task start\n \n task.cancel()\n\n with pytest.raises(asyncio.CancelledError):\n await task \n```\nTesting this behavior confirms graceful shutdowns of async operations when cancelled by external events[3][4].\n\n### 5. Using Hypothesis for Property-Based Testing of Async Code \n\nHypothesis supports property-based testing where input data are generated systematically to uncover edge cases.\n\nFor asynchronous code:\n \n - Combine Hypothesis strategies with `@pytest.mark.asyncio`.\n - Write hypothesis-powered test functions returning futures/coroutines whose results get asserted against expected properties.\n \nExample skeleton usage pattern:\n \n```python\nfrom hypothesis import given, strategies as st\n\n\n@pytest.mark.asyncio \n@given(st.integers())\nasync def test_property(x):\n result = await some_async_function(x)\n assert some_property(result)\n```\nUsing Hypothesis can reveal subtle bugs resulting from unusual inputs often missed by example-based tests[3].\n\n\n## Summary Table of Best Practices for Testing Async Python Applications \n\n| Aspect | Best Practice | Tools / Techniques |\n|------------------------|----------------------------------------------|--------------------------------------|\n| Testing async funcs | Use @pytest.mark.asyncio; define async tests | pytest + pytest-asyncio |\n| Mocking | UseAsyncMock() or similar; mock awaited returns | unittest.mock.AsyncMock |\n| Error handling | Assert exception raising asynchronously | Pytest raises context |\n| Cancellation | Test explicit cancels; expect CancelledError | asyncio Task.cancel(), Pytest |\n| Property-based testing | Combine Hypothesis strategies + @pytest.mark.asyncios | Hypothesis + Pytest |\n\n---\n\nFollowing these practices ensures comprehensive coverage, maintainability, reliability, reproducibility, and clear reasoning about concurrency-related behaviors when writing unit/integration tests for Python's asynchronous programs[1][3][4]." + }, + "delta": { + "role": "assistant", + "content": "" + } + } + ] +} +```` + +### Appendix B: Configuration Examples + +_Sample config files or environment variables related to testing, if any._ + +### Appendix C: Additional Code Samples + +_More extensive code examples if needed, beyond what's in the main body._ diff --git a/.khive/reports/tds/TDS-100.md b/.khive/reports/tds/TDS-100.md new file mode 100644 index 0000000..3559ac0 --- /dev/null +++ b/.khive/reports/tds/TDS-100.md @@ -0,0 +1,594 @@ +--- +title: "Technical Design Specification: Migration to lionfuncs (Issue #100)" +by: "@khive-architect" +created: "2025-05-22" +updated: "2025-05-22" +version: "1.1" +doc_type: "TDS" +identifier: "100" +output_subdir: "tds" +description: "Technical Design Specification for migrating khive's internal network and concurrency infrastructure to the external lionfuncs package, addressing Issue #100." +--- + +# Guidance + +**Purpose**\ +Lay out an **implementation-ready** blueprint for migrating `khive`'s external +API connectivity layer to utilize the `lionfuncs` package.

Interface Definitions + +### 3.1 API Endpoints (khive CLI - Unchanged for User) + +The user-facing CLI commands (e.g., `khive info search`, `khive info consult`) +will retain their existing signatures. The changes are internal to their +implementation. + +### 3.2 Internal Interfaces (`khive` services to `lionfuncs`) + +`khive` services will interact with `lionfuncs` through its defined Python API. + +**Example: `InfoService` using `lionfuncs` (Conceptual)** + +```python +# Conceptual representation within InfoService +from lionfuncs.network import NetworkExecutor, EndpointConfig # Hypothetical imports +from lionfuncs.models import RequestModel, ResponseModel # Hypothetical imports + +class InfoService: + def __init__(self, lionfuncs_executor: NetworkExecutor): + self._executor = lionfuncs_executor + # Configuration for Exa, Perplexity, etc., would be prepared here + # or passed to lionfuncs.EndpointConfig instances. + + async def search_exa(self, query: str) -> ResponseModel: + exa_endpoint_config = EndpointConfig( + base_url="https://api.exa.ai", + # ... other Exa specific configs like auth, method, path + ) + request_data = RequestModel(payload={"query": query}) # Simplified + # (pplx: lionfuncs-Network-Executor-Usage-Guide) + response = await self._executor.execute( + endpoint_config=exa_endpoint_config, + request_data=request_data + ) + return response # Assuming response is a parsed model + + async def consult_llm(self, model_id: str, prompt: str) -> ResponseModel: + # (pplx: lionfuncs-Network-Client-Guide) + # Similar pattern using an AsyncAPIClient or the NetworkExecutor + # with appropriate EndpointConfig for the LLM. + pass +``` + +This implies `lionfuncs` will provide mechanisms for configuring endpoints, +authentication, request bodies, and will return parsed response models or handle +raw responses. + +## 4. Data Models + +### 4.1 API Models (`khive` CLI - Unchanged for User) + +Input and output structures for `khive` CLI commands are expected to remain +consistent to avoid breaking changes for users. + +### 4.2 Domain Models (`khive`) + +Models within `khive` services (e.g., representing search results or LLM +responses) might need adaptation if `lionfuncs` returns data structured +differently than the previous internal clients. The goal is to map `lionfuncs` +responses to `khive`'s existing or slightly modified domain models. + +### 4.3 Database Schema (`khive`) + +This migration is not expected to directly impact `khive`'s database schema, as +it primarily concerns external API interactions. + +## 5. Behavior + +### 5.1 Core Workflows (using `lionfuncs`) + +**Workflow: `khive info search`** + +1. `khive` CLI parses the command and arguments. +2. Invokes `InfoService.search(provider, query, options)`. +3. `InfoService` determines the target external API (e.g., Exa, Perplexity). +4. `InfoService` prepares a `lionfuncs.EndpointConfig` and + `lionfuncs.RequestModel` (or similar) specific to the provider. This includes + API keys, URLs, and request payloads. +5. `InfoService` calls the appropriate `lionfuncs` method (e.g., + `lionfuncs.NetworkExecutor.execute()`). (pplx: + lionfuncs-Network-Executor-Usage-Guide) +6. `lionfuncs` handles the HTTP request, including authentication, rate limiting + (if provided by `lionfuncs`), retries (if provided), and concurrency + management. (pplx: lionfuncs.concurrency) +7. `lionfuncs` returns a response (e.g., `lionfuncs.ResponseModel`) to + `InfoService`. +8. `InfoService` processes the response, maps it to `khive` domain models, and + returns it to the CLI. +9. CLI formats and displays the result. + +**Workflow: `khive info consult`** Similar to search, but targets LLM APIs. +`InfoService` would use `lionfuncs` (perhaps an `AsyncAPIClient` or the +`NetworkExecutor`) to send prompts to specified models and receive responses. +(pplx: lionfuncs-Network-Client-Guide) + +### 5.2 Error Handling + +- `lionfuncs` is expected to raise specific exceptions for network errors, API + errors (e.g., 4xx, 5xx status codes), timeouts, etc. +- `khive`'s `InfoService` and other refactored components must catch these + `lionfuncs` exceptions. +- These exceptions will be mapped to `khive`'s existing error hierarchy (e.g., + `APIError`, `ConnectionTimeoutError` in `src/khive/clients/errors.py`, which + might be preserved or adapted) or new, more specific errors if necessary. +- User-facing error messages from the CLI should remain informative and + consistent. + +### 5.3 Security Considerations + +- **API Key Management:** `khive` will still be responsible for securely storing + and retrieving API keys for external services. These keys will now be passed + to `lionfuncs` during the configuration of its clients or endpoint objects. + The mechanism within `khive` for loading these keys (e.g., from environment + variables, config files) will remain. +- **Data in Transit:** Assumed that `lionfuncs` uses HTTPS for all external API + calls, ensuring data encryption in transit. +- **Input Sanitization:** `khive` remains responsible for sanitizing user inputs + before passing them to `lionfuncs` to prevent injection-style attacks if + payloads are constructed dynamically. + +## 6. External Interactions (now via `lionfuncs`) + +### 6.1 Dependencies on Other Services + +All direct dependencies of `khive` on external APIs (Exa, Perplexity, OpenAI, +Anthropic, etc.) will now be indirect, mediated entirely by `lionfuncs`. + +### 6.2 External API Integrations + +The logic for constructing API requests, handling authentication, and parsing +responses for each specific external service will be encapsulated within +`lionfuncs` configurations or adapters used by `InfoService`. + +**Conceptual `InfoService` interaction:** + +```python +# In InfoService +# (pplx: lionfuncs-Network-Client-Guide) +# (pplx: lionfuncs-Network-Executor-Usage-Guide) +async def _call_external_api(self, service_name: str, request_details: dict): + # 1. Select/construct lionfuncs.EndpointConfig based on service_name + # 2. Prepare lionfuncs.RequestModel from request_details + # 3. Use self._lionfuncs_executor.execute(endpoint_config, request_model) + # 4. Process lionfuncs.ResponseModel + pass +``` + +## 7. Performance Considerations + +### 7.1 Expected Load + +The expected load on `khive` services remains unchanged. + +### 7.2 Scalability Approach + +The scalability of handling concurrent external API calls will now largely +depend on `lionfuncs`'s architecture (e.g., its use of async operations, +connection pooling, and concurrency primitives like `BoundedQueue`). (pplx: +lionfuncs-Async-Operations-Guide, pplx: lionfuncs.concurrency) `khive` must +efficiently utilize these `lionfuncs` features. + +### 7.3 Optimizations + +- Code simplification within `khive` may lead to minor performance improvements + due to reduced overhead. +- Overall performance for external calls will be dictated by `lionfuncs`'s + efficiency. + +### 7.4 Caching Strategy + +- If `khive` currently implements caching for external API responses, this logic + will need to be reviewed. +- **Option 1:** Retain caching in `khive` services, caching the results obtained + from `lionfuncs`. +- **Option 2:** If `lionfuncs` provides its own caching mechanisms, `khive` + might leverage that. This is preferred if `lionfuncs` caching is robust. +- The decision will depend on `lionfuncs`'s features and the complexity of + adapting `khive`'s existing caching. + +## 8. Observability + +### 8.1 Logging + +- `khive` services will continue to log their operations. +- It's crucial that `lionfuncs` provides adequate logging for its operations + (request/response summaries, errors). +- `khive` should configure `lionfuncs` logging (if possible) to integrate with + `khive`'s logging system (format, level, handlers) to provide a unified view + of a request's lifecycle. +- Correlation IDs should be passed from `khive` to `lionfuncs` (if supported) to + trace requests across service boundaries. + +### 8.2 Metrics + +- `khive` should continue to expose metrics for its service endpoints. +- If `lionfuncs` exposes metrics (e.g., external call latency, error counts per + endpoint, queue lengths from `lionfuncs.concurrency`), `khive` should + integrate or re-expose these to provide a complete operational picture. + +### 8.3 Tracing + +- If `khive` uses distributed tracing, `lionfuncs` must support context + propagation for trace IDs. +- Instrumentation within `lionfuncs` calls from `khive` will be necessary to + include `lionfuncs` operations in `khive`'s traces. + +## 9. Testing Strategy + +### 9.1 Unit Testing + +- Unit tests for `khive` services (e.g., `TestInfoService`) will need to be + updated. +- Instead of mocking `khive.clients.ApiClient` or specific connection objects, + tests will now mock the interfaces of `lionfuncs` components (e.g., + `MockLionfuncsNetworkExecutor`, `MockLionfuncsAsyncAPIClient`). +- Focus on testing `khive`'s logic for preparing requests for `lionfuncs`, + handling responses from `lionfuncs`, and error mapping. + +### 9.2 Integration Testing + +- **Current State:** Integration tests likely exist that make real calls to + external APIs through `khive`'s old infrastructure. +- **Post-Migration:** These tests are critical for verifying the migration. + - They should be updated to run against `khive` services that now use + `lionfuncs` internally. + - The goal is to confirm that `khive` can still successfully communicate with + external services via `lionfuncs`. + - This might involve: + - Allowing passthrough to actual external APIs in a controlled (e.g., + sandboxed or rate-limited) test environment. + - Using a mocking/proxy layer at the boundary of `lionfuncs` if `lionfuncs` + itself supports such test harnesses. + - Verifying that `khive info search` and `khive info consult` still return + expected (or correctly formatted error) results. + +### 9.3 Performance Testing + +- If performance benchmarks exist for operations involving external calls, they + should be re-run after migration to compare `khive`+`lionfuncs` performance + against the old infrastructure. + +## 10. Deployment and Configuration + +### 10.1 Deployment Requirements + +- `lionfuncs` must be added as a runtime dependency to `khive`'s + `pyproject.toml`. +- Ensure the `lionfuncs` package is installed in all deployment environments. + +### 10.2 Configuration Parameters + +- **Removal:** Configuration parameters related to `khive`'s old + client/connection infrastructure (e.g., specific timeout settings, retry + strategies if now handled by `lionfuncs`, old endpoint URLs if `lionfuncs` + manages them differently) should be removed. +- **Addition/Modification:** + - `khive` may need new configuration parameters for initializing/configuring + `lionfuncs` components if not handled by `lionfuncs` itself (e.g., global + settings for `lionfuncs.NetworkExecutor`). + - API keys for external services will still be configured in `khive` but will + be passed to `lionfuncs` components. + +**Example (Conceptual `khive` config change):** + +```diff + # Old khive config (e.g., in a .env or settings file) + - KHIVE_CLIENT_TIMEOUT=30 + - KHIVE_CLIENT_MAX_RETRIES=3 + - EXA_API_ENDPOINT="https://api.exa.ai/search" + + # New/Retained khive config + EXA_API_KEY="your_exa_key" # Still needed by khive to pass to lionfuncs + # Potentially: + # LIONFUNCS_GLOBAL_TIMEOUT=25 # If lionfuncs allows such global settings +``` + +## 11. Migration Plan + +1. **Phase 1: Setup and Initial `InfoService` Refactoring** a. **Add `lionfuncs` + Dependency:** i. Add `lionfuncs` to `khive`'s `pyproject.toml`. ii. Run + `uv pip install lionfuncs` (or `uv sync` if `lionfuncs` is added to + `pyproject.toml`). b. **Understand `lionfuncs` API:** Thoroughly review + `lionfuncs` documentation ("Network Executor Usage Guide," "Network Client + Guide," "Async Operations Guide," "lionfuncs.concurrency") to understand its + API, configuration, and error handling. (pplx: all-lionfuncs-docs) c. + **Refactor `InfoService` (Core Logic):** i. Modify + `src/khive/services/info/info_service.py` to use `lionfuncs` for one provider + (e.g., Exa). ii. Instantiate and configure the relevant `lionfuncs` + client/executor. iii. Adapt request creation, response handling, and error + mapping for this provider. d. **Update Unit Tests:** Adapt unit tests for the + refactored part of `InfoService`, mocking `lionfuncs`. + +2. **Phase 2: Complete `InfoService` and CLI Refactoring** a. **Refactor + `InfoService` (Remaining Providers):** Extend the refactoring to all other + providers used by `InfoService` (Perplexity, other LLMs). b. **Refactor CLI + Commands:** Update `src/khive/commands/info.py` and any other CLI command + implementations that use `InfoService` or the old client infrastructure to + align with the `InfoService` changes. c. **Update Unit Tests:** Complete unit + test updates for `InfoService` and CLI commands. + +3. **Phase 3: Removal of Old Infrastructure** a. **Identify Redundant Code:** + Pinpoint all modules, classes, and functions in + [`src/khive/clients/`](src/khive/clients/:0) (e.g., + [`api_client.py`](src/khive/clients/api_client.py:0), + [`executor.py`](src/khive/clients/executor.py:0), + [`queue.py`](src/khive/clients/queue.py:0), + [`rate_limiter.py`](src/khive/clients/rate_limiter.py:0), + [`resilience.py`](src/khive/clients/resilience.py:0)) and within + [`src/khive/connections/`](src/khive/connections/:0) (excluding the + [`src/khive/connections/providers/`](src/khive/connections/providers/:0) + subdirectory, which will be retained for its Pydantic models serving as + prompts/manuals). Components like + [`endpoint_config.py`](src/khive/connections/endpoint_config.py:0), + [`endpoint.py`](src/khive/connections/endpoint.py:0), + [`header_factory.py`](src/khive/connections/header_factory.py:0), and + [`match_endpoint.py`](src/khive/connections/match_endpoint.py:0) should be + reviewed for removal if their execution-related functionality is fully + superseded by `lionfuncs`. b. **Systematic Deletion:** Carefully delete the + identified redundant code. c. **Remove Old Configurations:** Remove any + configuration parameters that are no longer needed. d. **Clean Up Imports:** + Remove unused imports throughout the `khive` codebase. + +4. **Phase 4: Integration Testing and Documentation** a. **Run/Adapt Integration + Tests:** Execute and adapt existing integration tests to ensure they pass + with `khive` using `lionfuncs`. Verify end-to-end functionality for + `khive info search/consult`. b. **Update Internal Documentation:** Update any + `khive` internal documentation, READMEs, or developer guides that refer to + the old connection infrastructure. c. **Code Review and Refinement:** Conduct + thorough code reviews of all changes. + +## 12. Risks and Mitigations + +1. **Risk:** `lionfuncs` API or behavior differs significantly from assumptions + made based on documentation titles. + - **Mitigation:** Allocate time for a thorough `lionfuncs` API review (Step + 1b of Migration Plan). If major discrepancies are found, reassess the + migration plan and potentially raise concerns with the `lionfuncs` team or + @khive-orchestrator. +2. **Risk:** `lionfuncs` lacks critical features previously handled by `khive`'s + internal infrastructure (e.g., specific rate limiting strategies, complex + retry logic not covered by `lionfuncs`). + - **Mitigation:** Identify gaps early during the `lionfuncs` review. Discuss + with @khive-orchestrator whether these features need to be re-implemented + in `khive` on top of `lionfuncs`, contributed to `lionfuncs`, or if the + requirement can be relaxed. +3. **Risk:** Difficulty in mapping `lionfuncs` error types to `khive`'s existing + error handling, leading to inconsistent error reporting. + - **Mitigation:** Define a clear mapping strategy during the `InfoService` + refactoring. Create new `khive` exceptions if necessary. Prioritize clear + user-facing error messages. +4. **Risk:** Performance degradation after migrating to `lionfuncs`. + - **Mitigation:** Conduct performance testing (Section 9.3) if benchmarks + exist. If degradation is observed, profile `khive`+`lionfuncs` interactions + to identify bottlenecks. Consult `lionfuncs` documentation for performance + tuning or raise issues if `lionfuncs` appears to be the bottleneck. +5. **Risk:** Integration testing becomes more complex or less reliable due to + the new abstraction layer. + - **Mitigation:** Investigate `lionfuncs`'s support for test harnesses or + mocking. If unavailable, develop robust mocking strategies for `lionfuncs` + at `khive`'s boundary for reliable integration tests. +6. **Risk:** Incomplete removal of old `khive` infrastructure, leading to dead + code or unexpected behavior. + - **Mitigation:** Perform a careful audit of `src/khive/clients/` and + `src/khive/connections/` during Phase 3 of the migration. Use code analysis + tools to find unused code if possible. + +## 13.

Overview + +### 1.1 Purpose + +This document outlines the technical design for refactoring the Khive Reader +service's document ingestion pipeline. The primary goal is to integrate the +`pydapter` library for all data persistence and interaction tasks, replacing +previous custom solutions for database and potentially object storage +management. This change aims to leverage `pydapter`'s adapter pattern, Pydantic +model integration, and event-driven capabilities to create a more robust, +maintainable, and extensible ingestion system. + +### 1.2 Scope + +**In Scope:** + +- Redesign of data persistence for `Document` and `DocumentChunk` models using + `pydapter` adapters. +- Re-evaluation and potential redesign of object storage interactions + (`ObjectStorageClient`) using or integrating with `pydapter`. +- Refactoring of the `DocumentIngestionService` to utilize `pydapter` for its + core operations. +- Definition of how CRUD operations and vector searches on `DocumentChunk` will + be performed via `pydapter`. +- Consideration of `pydapter`'s event model (e.g., `@as_event`) for asynchronous + processing within the ingestion pipeline. +- Outline of impacts on downstream processes like text extraction, chunking, and + embedding (Issue #27). + +**Out of Scope:** + +- Detailed implementation of `pydapter` adapters if custom ones are needed (this + TDS will specify the need and high-level design). +- Full implementation details of downstream processing services (text + extraction, embedding), though their interaction points will be considered. +- UI/CLI command implementation details for `khive reader ingest`, beyond how it + triggers the `DocumentIngestionService`. + +### 1.3 Background + +The Khive Reader service requires an efficient pipeline to ingest various +document types, store them, process them into manageable chunks, and make them +available for embedding and search. Previous design discussions (Issue #26, +Issue #25) outlined components like `ObjectStorageClient` and +`DocumentRepository`. + +A new critical requirement mandates the use of the `pydapter` library for data +persistence and interactions. `Pydapter` (as understood from provided context in +Issue #26 comments and available `pydapter` source code (e.g., +[`pydapter.async_core.AsyncAdaptable`](https://github.com/khive-ai/pydapter/blob/main/src/pydapter/async_core.py#L92), +[`pydapter.protocols.event.@as_event`](https://github.com/khive-ai/pydapter/blob/main/src/pydapter/protocols/event.py#L63)) +is an asynchronous library featuring an adapter pattern, deep integration with +Pydantic models (via the `AsyncAdaptable` mixin), and an event model driven by +the `@as_event` decorator. This TDS refactors the ingestion architecture to +align with `pydapter`. + +Relevant Issues: + +- Issue #26: "Implement `khive reader ingest` command" - Core ingestion logic. +- Issue #25: "Design `DocumentRepository`" - Now superseded/refactored by + `pydapter`. +- Issue #24: "Define `Document` and `DocumentChunk` Pydantic Models" - These + models will be made `pydapter`-compatible. +- Issue #27: "Implement Text Extraction, Chunking, and Embedding" - Downstream + consumers of ingested data. + +### 1.4 Design Goals + +- **Pydapter-centric Architecture:** Fully leverage `pydapter` for data + persistence and interactions. +- **Modularity:** Design components (services, adapters) with clear + responsibilities. +- **Asynchronous Operations:** Ensure the pipeline is fully asynchronous, + utilizing `pydapter`'s async capabilities. +- **Extensibility:** Allow for easy addition of new document types or `pydapter` + adapters in the future. +- **Maintainability:** Simplify data access logic by using `pydapter`'s + abstractions. +- **Testability:** Design components that are easily testable, especially + interactions with `pydapter` adapters. + +### 1.5 Key Constraints + +- **Mandatory `pydapter` Usage:** All data persistence and related interactions + must use `pydapter`. +- **Pydantic Models:** `Document` and `DocumentChunk` (Issue #24) are Pydantic + models and must be integrated with `pydapter` by inheriting from + `pydapter.async_core.AsyncAdaptable`. +- **Asynchronous Nature:** The entire ingestion pipeline must be asynchronous. +- **Compatibility:** The solution must be compatible with chosen database (e.g., + PostgreSQL for metadata, Qdrant for vectors) and local object storage (e.g., + MinIO running in Docker, or local filesystem via pydapter if suitable). + +## 2.

The + `pydapter.model_adapters.postgres_model.PostgresModelAdapter` handles + Pydantic-to-SQLAlchemy model conversion, including types like `JSONB` for + `Document.metadata`. +- **Qdrant:** Collection (`document_chunks`) creation and configuration (vector + size, distance metric) must be handled. The `AsyncQdrantAdapter.to_obj` + method, as seen in source, attempts to `recreate_collection`. This behavior + needs careful management in a production setup to avoid data loss. It's + recommended to ensure the collection exists with the correct configuration + before the ingestion service starts or modify adapter usage to only upsert. + +- **PostgreSQL (`Document` table):** Columns corresponding to `Document` model + fields. +- **Qdrant (`DocumentChunk` collection):** Fields corresponding to + `DocumentChunk` model fields, with a vector field for `embedding`. + +## 5. Behavior + +### 5.1 Core Workflows + +**A. Document Ingestion (Happy Path):** + +1. `khive reader ingest --metadata '{"key": "value"}'` is executed. +2. CLI invokes `DocumentIngestionService.ingest_document(file_path, metadata)`. +3. `DocumentIngestionService`: a. Uses `DocumentObjectAdapter` to upload the raw + file from `file_path` to local object storage (e.g., MinIO via Docker). Gets + back `storage_uri`. b. Constructs a `Document` Pydantic model instance with + `source_uri`, `storage_uri`, `mime_type`, user `metadata`, and initial + `status` (e.g., "UPLOADED"). c. Uses + `DocumentMetadataAdapter.to_obj(document_model, table="documents")` to + persist the `Document` record in PostgreSQL. d. **Event Triggering using + `pydapter @as_event`**: A service method responsible for calling + `DocumentMetadataAdapter.to_obj` (or the `to_obj` call itself if the adapter + method could be decorated, though less likely for generic adapters) can be + decorated with + [`@as_event`](https://github.com/khive-ai/pydapter/blob/main/src/pydapter/protocols/event.py#L63). + Example: + ```python + # In DocumentIngestionService or a dedicated event-sourcing part + # @as_event(adapter=self.event_log_adapter_class, adapt=True, event_type="DocumentMetadataStored") + # async def _persist_doc_and_log_event(self, doc: Document): + # await self.metadata_adapter.to_obj(doc, table="documents") # Or use doc.adapt_to_async + # return {"document_id": doc.id, "status": "METADATA_STORED"} + ``` + When `_persist_doc_and_log_event` is called, `pydapter` will: i. Execute the + function. ii. Create an `Event` object capturing its request and response. + iii. If `adapt=True` and an `adapter` (e.g., for an SQL event log table) is + provided to `@as_event`, it will convert the `Event` to a `Log` object (see + [`pydapter.protocols.event.Event.to_log`](https://github.com/khive-ai/pydapter/blob/main/src/pydapter/protocols/event.py#L38)) + and persist it using the specified `event_log_adapter`. This `Log` object + contains details like `event_type`, `content` (request/response of the + decorated function), `status`, `duration`, etc. +4. Downstream Processing (Issue #27 - Text Extraction, Chunking, Embedding): a. + A listener/worker picks up the `DocumentCreatedEvent` (or queue message). b. + **Text Extraction:** i. Uses `DocumentObjectAdapter` to download the raw + document content from `storage_uri`. ii. Extracts text. iii. Uses + `DocumentObjectAdapter` to upload extracted text to local object storage. + Gets `extracted_text_uri`. iv. Uses `DocumentMetadataAdapter.update()` to + save `extracted_text_uri` and update `Document.status` (e.g., + "TEXT_EXTRACTED"). c. **Chunking:** i. Uses `DocumentObjectAdapter` to + download extracted text. ii. Chunks the text into `DocumentChunk` Pydantic + models, linking them to `document_id`. d. **Embedding:** i. Generates vector + embeddings for each `DocumentChunk.text`. ii. Updates `DocumentChunk` models + with their embeddings. e. Uses + `DocumentChunkAdapter.to_obj(list_of_chunks, collection="document_chunks", vector_field="embedding", id_field="id")` + to store all chunks and their embeddings in Qdrant. (Note: + `AsyncQdrantAdapter.to_obj` takes `Sequence[T]`, so a list of chunks is + appropriate). f. Uses + `DocumentMetadataAdapter.to_obj(updated_document_model, table="documents", update_existing=True)` + (assuming `AsyncSQLAdapter` supports an `update_existing` or similar flag for + upsert/update, or a separate update method) to set `Document.status` to + "COMPLETED". If not, a specific update method via `from_obj` with selectors + and then `to_obj` or a dedicated update method in `AsyncSQLAdapter` would be + needed. +5. `DocumentIngestionService.ingest_document` returns the initial `Document` + model (or an ID/status). + +**B. Vector Search on Chunks:** + +1. A search service receives a query. +2. Query is embedded to get `query_embedding`. +3. Search service uses + `DocumentChunkAdapter.from_obj(DocumentChunk, {"collection": "document_chunks", "query_vector": query_embedding, "top_k": N})` + to find relevant chunks from Qdrant. +4. Results are processed and returned. + +### 5.2 Error Handling + +- **Adapter Errors:** `pydapter` adapters should raise specific exceptions for + database/storage connection issues, query failures, object not found, etc. + (see + [`pydapter.exceptions`](https://github.com/khive-ai/pydapter/blob/main/src/pydapter/exceptions.py)). +- **`DocumentIngestionService`**: Will catch exceptions from adapters and + internal logic. + - Transient errors (e.g., network issues) might be handled with retries + (possibly managed by `pydapter` or a resilience library). + - Persistent errors will result in the `Document.status` being set to "FAILED" + with error details stored in `Document.metadata`. +- **Downstream Processing Errors:** Errors in text extraction, chunking, or + embedding should update the `Document.status` to "FAILED" and log details. +- **Validation Errors:** Pydantic models will provide data validation. + `pydapter` should handle or propagate these. + +### 5.3 Security Considerations + +- **Credentials Management:** Database, object storage, and `pydapter` (if it + has its own auth) credentials must be securely managed (e.g., via environment + variables, secrets manager). `pydapter` adapters will be configured with these + credentials. +- **Data in Transit:** Ensure TLS is used for connections to PostgreSQL and + Qdrant. For local MinIO (Docker), configure TLS if accessing over a network + interface; for direct filesystem access, this is less relevant but ensure + proper file permissions. +- **Data at Rest:** Encryption for data at rest in object storage and databases + should be configured at the storage/DB level if required. +- **Input Sanitization:** While Pydantic handles type validation, be mindful of + any string inputs that might be used in constructing queries if `pydapter` + allows raw query components (though typically it abstracts this). + +## 6. External Interactions + +### 6.1 Dependencies on Other Services + +- **PostgreSQL Database:** For storing `Document` metadata. Accessed via + `DocumentMetadataAdapter`. +- **Qdrant/Vector Database:** For storing `DocumentChunk` objects and their + embeddings. Accessed via `DocumentChunkAdapter`. +- **Local Object Storage (e.g., MinIO via Docker or direct filesystem access + managed by pydapter):** For storing raw documents and extracted text.

Performance Considerations + +### 7.1 Expected Load + +- The system should handle ingestion of hundreds to thousands of documents per + day initially. +- Document sizes can vary from KBs to tens of MBs. +- Vector search queries will depend on application usage. + +### 7.2 Scalability Approach + +- **Asynchronous Processing:** The use of `async` operations and `pydapter`'s + async capabilities is fundamental. +- **Stateless Services:** `DocumentIngestionService` and downstream processing + components should be designed as stateless as possible to allow horizontal + scaling. +- **Database/Storage Scaling:** PostgreSQL and Qdrant (running locally, perhaps + in Docker) have their own scaling considerations for a local setup (resource + allocation to Docker). Local MinIO (Docker) also scales based on allocated + resources. Direct filesystem storage scales with disk space. +- **`pydapter` Performance:** Assumed to be efficient.

Risks & Mitigations + +### 11.1 Risk: `pydapter` Feature Gaps or Misinterpretation + +- **Description:** The design relies on assumed capabilities of `pydapter` + (e.g., specific adapter availability for local MinIO/filesystem, event model + details, migration handling) based on limited information. Actual features + might differ or require more custom development. +- **Mitigation:** + 1. **Early Spike/PoC:** The Implementer should conduct an early + proof-of-concept with `pydapter` and the target databases/storage to + validate core assumptions as soon as the actual `pydapter` documentation is + fully reviewed (e.g., by studying its source code at + `https://github.com/khive-ai/pydapter`). + 2. **Flexible Adapter Design:** Design custom adapters (if needed) with a + clear interface, allowing for easier replacement or modification if + `pydapter`'s native support is different. + 3. **Iterative Refinement:** Be prepared to iterate on this TDS based on + findings from the PoC. + +### 11.2 Risk: Complexity of Custom `pydapter` Adapters + +- **Description:** If `pydapter` does not provide out-of-the-box adapters for + all needed local systems (especially for local MinIO Docker interaction or + robust filesystem object storage, as these are not explicitly provided by + `pydapter`), developing robust, async custom adapters can be complex and + time-consuming. +- **Mitigation:** + 1. **Prioritize Native Adapters:** Thoroughly investigate if `pydapter` or its + ecosystem offers existing solutions before committing to custom + development. + 2. **Simplified Custom Adapter Scope:** If custom adapters are necessary, + start with the minimal required functionality and iterate. + 3. **Leverage Existing Libraries:** Build custom adapters on top of + well-tested underlying client libraries (e.g., `minio-py` for local MinIO, + Python's `aiofiles` for filesystem). + +### 11.3 Risk: Performance Overheads of `pydapter` + +- **Description:** While `pydapter` is assumed to be performant, any abstraction + layer can introduce overhead. Specific adapter implementations or general + `pydapter` mechanics might impact ingestion speed or query latency. +- **Mitigation:** + 1. **Performance Testing:** Conduct thorough performance testing early in the + implementation phase, focusing on critical paths like batch chunk saving + and vector search. + 2. **Consult `pydapter` Documentation:** Review `pydapter` performance + guidelines and best practices by reviewing its source and examples. + 3. **Direct Client Fallback (Contingency):** In extreme cases, for highly + performance-critical operations where `pydapter` overhead is prohibitive, + consider if a direct client library usage for that specific operation is + feasible as a last resort, while still using `pydapter` for other + operations. This should be avoided if possible to maintain consistency. + +## 12. Open Questions + +1. **`pydapter` Local Object Storage Adapter:** Does `pydapter` provide a + generic adapter suitable for local object storage (like a Dockerized MinIO + instance via its S3-compatible API, or direct filesystem object management)? + If not, what is the recommended pattern for integrating such local storage + (e.g., custom adapter development guidelines)? The `pydapter` source does not + show a built-in adapter for this. +2. **`pydapter` Event Model Details:** What are the specific mechanisms and + guarantees of `pydapter`'s event model (e.g., `@as_event`)? How are events + published, subscribed to, and what are the delivery semantics (at-least-once, + at-most-once)? The + [`@as_event` decorator](https://github.com/khive-ai/pydapter/blob/main/src/pydapter/protocols/event.py#L63) + allows persisting an event `Log` via another adapter; delivery semantics + would depend on that secondary adapter and any message bus if used. +3. **`pydapter` Migration Handling:** Does `pydapter` include a database + migration system (e.g., via + [`pydapter.migrations.sql.alembic_adapter.py`](https://github.com/khive-ai/pydapter/blob/main/src/pydapter/migrations/sql/alembic_adapter.py) + for SQL databases like PostgreSQL)? Or is schema management expected to be + handled externally (manual for Qdrant collections is likely)? +4. **`pydapter` Transaction/Unit of Work:** How does `pydapter` handle + transactions or units of work across multiple adapter operations, if at all? + This is important for ensuring consistency, e.g., when saving a `Document` + and then triggering an event. + +## 13. Appendices + +### Appendix A: Alternative Designs + +- **No `pydapter` (Original Design):** The original approach involved custom + repositories and clients (Issue #25, #26). This was superseded by the + requirement to use `pydapter`. +- **Partial `pydapter` Adoption:** Using `pydapter` only for database + interactions and keeping a separate `ObjectStorageClient`.

Lifecycle Management + +### 5.1 Initialization + +- **`lionfuncs.network.Executor`:** + - An instance of `NetworkExecutor` should be created globally or per + application scope within `khive` (e.g., when the `khive` application starts + or on first use by a service). + - Configuration for the executor (e.g., global concurrency limits, default + rate limits if not per-endpoint) would be passed during its instantiation. + - This executor instance will be injected into `khive` services (like + `InfoService`). +- **`khive` Services (e.g., `InfoService`):** + - Instantiated with a reference to the shared `lionfuncs.network.Executor`. + - Load their specific configurations (e.g., how to prepare `EndpointConfig` + for various external APIs). + +### 5.2 Startup + +- The `lionfuncs.network.Executor` might have an explicit startup phase if it + needs to initialize internal resources (e.g., worker pools, internal queues). + This should be called during `khive`'s application startup. +- If `lionfuncs.network.AsyncAPIClient` instances are managed by `khive` + services (less likely if Executor handles endpoints), they would be + initialized, potentially using async context managers. + +### 5.3 Execution + +- `khive` services prepare `EndpointConfig` and `RequestModel` objects. +- These are passed to the `lionfuncs.network.Executor.execute()` method. +- The Executor manages the call lifecycle, including rate limiting, retries, and + actual dispatch to the external API (likely via an internal `AsyncAPIClient` + or similar mechanism). + +### 5.4 Shutdown + +- **`lionfuncs.network.Executor`:** + - Must provide a graceful shutdown mechanism (e.g., + `await executor.shutdown(timeout=...)`). + - This should allow pending tasks to complete up to a certain timeout and + clean up all internal resources (threads, connections, queues). + - This shutdown method will be called during `khive`'s application shutdown + sequence. +- **`khive` Services:** + - If they manage any `lionfuncs` resources directly (e.g., client instances + not managed by the Executor), they must ensure these are closed during + shutdown, preferably using `async with` for individual clients if used + ad-hoc, or an explicit close if long-lived and managed by the service. + +### 5.5 Resource Cleanup + +- `lionfuncs` components are responsible for cleaning up their internal + resources (e.g., HTTP client sessions within `AsyncAPIClient` or the + `NetworkExecutor`). +- `khive` is responsible for ensuring that `lionfuncs` components it manages + (like the global `NetworkExecutor`) are properly shut down. +- Use of `async with` for any `lionfuncs` clients or resources that support the + context manager protocol is highly recommended within `khive` service methods + if they are created on-the-fly (though a central Executor is preferred). + +## 6. Error Handling + +- `lionfuncs` is expected to raise specific exceptions for network issues, API + errors, timeouts, rate limit exceeded errors, etc. (Ref: `TDS-100.md`, Section + 5.2). +- `khive` Service Layer will catch these `lionfuncs` exceptions and: + - Map them to appropriate `khive`-specific exceptions (e.g., from + [`src/khive/clients/errors.py`](src/khive/clients/errors.py:0), which may be + adapted). + - Log them with relevant context. + - Propagate them in a way that the `khive` CLI can present informative + messages to the user. + +## 7. Security Considerations + +- API Key Management: `khive` services will continue to manage API keys, passing + them to `lionfuncs` components (e.g., within `EndpointConfig`) as needed. + `lionfuncs` should not store these keys beyond the scope of a request or its + client configuration. +- `lionfuncs` is assumed to use HTTPS for all communications. + +## 8. Testing Strategy + +- **Unit Tests for `khive` Services:** + - Mock the `lionfuncs.network.Executor` interface. + - Verify that `khive` services correctly prepare `EndpointConfig` and + `RequestModel` for `lionfuncs`. + - Verify correct handling of responses and exceptions from the mocked + `Executor`. +- **Integration Tests:** + - Test the `khive` Service Layer interacting with a real (or well-mocked at + its boundary) `lionfuncs.network.Executor`. + - These tests might involve `lionfuncs` making calls to mock external API + servers or, in controlled environments, to actual sandboxed external APIs. + - Focus on the interaction between `khive` services and the `lionfuncs` layer. + +## 9. Risks and Mitigations + +- **Risk:** `lionfuncs.network.Executor` does not provide sufficient granularity + for rate limiting or concurrency control as envisioned by Issue #80. + - **Mitigation:** Early validation of `lionfuncs.network.Executor` + capabilities against Issue #80 requirements. If gaps exist, `khive` Service + Layer might need to implement additional controls using + `lionfuncs.concurrency` primitives before submitting tasks to the + `Executor`, or this needs to be flagged as a required enhancement for + `lionfuncs`. +- **Risk:** Complexity in managing the lifecycle of `lionfuncs` components. + - **Mitigation:** Ensure `lionfuncs` provides clear startup and shutdown + procedures. Implement robust lifecycle management in `khive`'s main + application setup and teardown. + +## 10. Open Questions + +- What are the precise configuration options for `lionfuncs.network.Executor` + regarding rate limits (per-host, per-endpoint, global)? +- How does `lionfuncs.network.Executor` manage authentication details?

Overview + +### 1.1 Component Under Test + +The `khive new-doc` CLI command, specifically its error handling and messaging +capabilities. The relevant source files are primarily +[`src/khive/cli/khive_new_doc.py`](src/khive/cli/khive_new_doc.py:0) and the +underlying command logic in +[`src/khive/commands/new_doc.py`](src/khive/commands/new_doc.py:0). Tests will +be located in +[`tests/cli/test_khive_new_doc.py`](tests/cli/test_khive_new_doc.py:0). + +### 1.2 Test Approach + +The primary focus will be on **unit tests** using `pytest`. These tests will +simulate various error conditions and verify that: + +1. The command exits with a non-zero status code. +2. The correct, user-friendly error message is printed to stderr for standard + output. +3. The correct JSON structure (`{"status": "error", "message": "..."}`) is + printed to stdout when `--json-output` is used. + +### 1.3 Key Testing Goals + +- Verify clear and actionable error messages for file-already-exists scenarios + (with and without `--force`). +- Verify clear error messages for template-not-found scenarios. +- Verify error messages for invalid/unwritable destination paths. +- Verify error messages for issues creating destination paths. +- (If applicable) Verify error messages for invalid identifiers. +- Ensure JSON output correctly reflects all error states. +- Maintain existing test coverage for successful command execution. + +## 2.

Overview + +### 1.1 Component Under Test + +This test plan covers the new components introduced for the Reader +Microservice's document processing pipeline, as specified in Issue #27. This +includes: + +- `src/khive/reader/tasks/queue.py` (`AsyncTaskQueue`) +- `src/khive/reader/processing/text_extraction.py` (`TextExtractor`) +- `src/khive/reader/processing/chunking.py` (`DocumentChunker`) +- `src/khive/reader/processing/embeddings.py` (`EmbeddingGenerator`) +- `src/khive/reader/services/processing_service.py` + (`DocumentProcessingService`) +- Task registration in `src/khive/reader/tasks/__init__.py` +- Modifications to the existing Ingestion Service. + +### 1.2 Test Approach + +A combination of unit tests and integration tests will be employed. + +- **Unit Tests:** Each new module and class will be tested in isolation, + focusing on its specific logic and error handling. Mocking will be used + extensively for external dependencies (APIs, repositories, other services). +- **Integration Tests:** Will verify the interaction between the newly developed + components, such as the `DocumentProcessingService` orchestrating the + `TextExtractor`, `DocumentChunker`, and `EmbeddingGenerator`. Further + integration tests will cover the flow from the updated Ingestion Service + through the `AsyncTaskQueue` to the `DocumentProcessingService`. + +### 1.3 Key Testing Goals + +- Verify correct functionality of each processing step: text extraction for all + supported formats, text chunking, and embedding generation (OpenAI and + fallback). +- Ensure the `DocumentProcessingService` correctly orchestrates the pipeline and + updates document statuses. +- Validate robust error handling at each stage of the pipeline. +- Confirm the `AsyncTaskQueue` correctly manages and dispatches tasks. +- Verify the updated Ingestion Service successfully queues documents for + processing. +- Achieve >=80% unit test coverage for all new code. + +## 2. Test Environment + +### 2.1 Test Framework + +```python +# Python +pytest +pytest-asyncio # For testing asynchronous code +pytest-mock # For mocker fixture +pytest-cov # For coverage reporting +``` + +### 2.2 Mock Framework + +```python +# For Python +unittest.mock # Standard library +pytest-mock # Provides mocker fixture, often preferred with pytest +``` + +### 2.3 Test Database + +Repositories (`DocumentRepository`, `DocumentChunkRepository`) will be mocked +for unit tests. For integration tests focusing on the pipeline logic, these will +also be mocked to avoid actual database interactions and keep tests fast and +isolated.

Error Handling Tests + +Error handling is a key part of the unit tests for `TextExtractor`, +`EmbeddingGenerator`, and `DocumentProcessingService`. Each component will be +tested for its resilience to failures in its dependencies or invalid inputs, +ensuring appropriate exceptions are raised or errors are logged and document +statuses are updated correctly. (Refer to specific error handling test cases in +IP-27.md, e.g., UT-TE5, UT-EG5, UT-PS2-PS5). + +## 7. Performance Tests + +Performance testing is not in the immediate scope of this TI but could be a +future improvement. If implemented, it would focus on: + +- Throughput of the `AsyncTaskQueue`. +- Processing time per document for `DocumentProcessingService` under various + loads and document sizes. +- Benchmarking `TextExtractor` and `EmbeddingGenerator` for different file + types/sizes. + +## 8. Mock Implementation Details + +Mocks will primarily use `pytest-mock`'s `mocker` fixture or `unittest.mock`. +Example for `DocumentRepository`: + +```python +from unittest.mock import MagicMock + +@pytest.fixture +def mock_document_repository(mocker): + mock_repo = mocker.MagicMock(spec=DocumentRepository) # Assuming DocumentRepository is defined + mock_repo.get_by_id = mocker.AsyncMock(return_value=MagicMock(id="doc1", status="PENDING", file_path_in_object_store="path/to/file.pdf")) + mock_repo.update_status = mocker.AsyncMock() + mock_repo.set_processed_text_path = mocker.AsyncMock() + return mock_repo +``` + +Similar mock fixtures will be created for `ObjectStorageClient`, +`DocumentChunkRepository`, `TextExtractor`, `DocumentChunker`, +`EmbeddingGenerator`, `openai.Embedding`, and `SentenceTransformer` as needed +for different test suites. + +## 9. Test Data + +- Sample files: Small, valid PDF, DOCX, HTML, TXT files. +- Corrupted/empty files for error testing. +- Sample text snippets of varying lengths for chunking tests. +- Expected extracted text for validation. +- Pre-computed (or expected format of) embeddings for assertion. + +Test data files will be stored likely in a `tests/fixtures/files` directory. + +## 10. Helper Functions + +- Fixtures for creating mock objects (as shown in section 8). +- Fixtures for providing paths to sample test files. +- Potentially, helper functions to create `Document` model instances for + repository mocks. + +## 11.
