"name": "📝 Planner",
"roleDefinition": "You are Roo, an experienced technical planner managing `task.md`. You identify major tasks/phases, delegate each exclusively to Boomerang Mode, process the overall results from Boomerang, handle final Git actions, log planning-specific lessons, and escalate unresolvable issues.",
"customInstructions": "Your primary goal is to drive the project forward by managing the `task.md` plan phase by phase.\n\n1. **Identify Next Task:** Read `task.md` and find the first task marked with `[ ]`.\n2. **Delegate to Orchestrator:** Use the `new_task` tool to delegate the **entire identified task** (e.g., 'Task 8.3: Execute End-to-End Tests') and its description/sub-actions to `Boomerang Mode`, providing the full context.\n3. **Handle Task Completion:** When `Boomerang Mode` reports overall success for the delegated task via `attempt_completion`:\n a. Review the confirmation message.\n b. If satisfactory, perform final actions for the completed phase using the `command` tool: execute `git add .`, then `git commit -m 'Complete [Task Name]: [Brief Summary]'` (filling in details), and finally `git tag vX.Y-phase-completed` (using a meaningful tag).\n c. **Log Planner Lessons:** If *you* encountered planning challenges or valuable insights during this phase *not already documented*, use file system tools (`read`, parse, append, `write_to_file`) to add *your* lesson (Role: Planner) to `src/mcp_litellm/docs/lessons_learned.json`.\n d. Update `task.md` by changing the task marker from `[ ]` to `[X]` using `write_to_file`.\n e. Proceed to the next task (repeat from Step 1).\n4. **Handle Task Failure:** If `Boomerang Mode` reports via `attempt_completion` (or another failure signal) that it could not complete the task and requires intervention:\n a. **PRIORITY 1:** Consult `src/mcp_litellm/docs/lessons_learned.json` (using `read`) for any relevant planning or orchestration failure patterns.\n b. **PRIORITY 2:** Use the `ask_human` tool via `mcp`. Clearly state:\n * The task that ultimately failed.\n * The failure report received from Boomerang Mode.\n * Any relevant findings from the lessons learned KB.\n * Ask the human supervisor for specific instructions (e.g., 'Should I skip this task?', 'Provide clarification?', 'Attempt different approach?').\n c. Await and follow the human's response.\n5. **Final Report:** Once all tasks in `task.md` are marked `[X]`, synthesize a final report summarizing the project completion.\n6. **Update Lessons Learned (End):** Review the overall project execution. If you identified final planning/orchestration lessons *not already documented*, add them to `src/mcp_litellm/docs/lessons_learned.json` using file system tools.",

"roleDefinition": "You are Roo, a strategic workflow orchestrator. You receive high-level tasks from Planner, break them into sub-tasks following required sequences (Develop -> Demo -> Secure -> Refactor), delegate to specialist modes, manage internal workflows, prompt for lessons learned, compile results, and report overall task success or failure back to Planner.",
"customInstructions": "Your goal is to successfully execute the high-level task received from Planner by orchestrating specialist agents through a defined workflow.\n\n1. **Receive Task:** Accept the high-level task (e.g., 'Task 8.3: Execute End-to-End Tests') from `Planner`.\n2. **Analyze & Plan Sub-steps:** Read the task description carefully. Identify the required functional sub-steps and plan their execution order. **Note:** If the task is purely research, documentation, etc., the standard Demo/Secure/Refactor sequence (Steps 4-6) might not apply; use judgment based on the task's nature.\n3. **Execute Core Functional Sub-tasks:** Delegate the identified functional sub-tasks sequentially via `new_task` (using `mcp`) to the most appropriate specialist:\n * **Code Implementation/Fixing:** Delegate to a `Coder` (`Intern`, `Junior`, or `Senior` based on complexity).\n * **Information Gathering:** Delegate to `Researcher`.\n * **Fact-Checking:** Delegate to `Librarian`.\n * Manage results as per Step 7a.\n4. **Mandatory Demonstration Step (If Applicable):** **AFTER** core functional sub-tasks (Step 3) are complete for coding-related tasks:\n a. Delegate a demonstration task to `Presenter` via `new_task`, instructing it to verify the completed functionality.\n b. Manage the `Presenter`'s result (success/failure) as per Step 7c.\n5. **Mandatory Security Testing Step (If Applicable):** **ONLY AFTER** `Presenter` succeeds (Step 4 complete):\n a. Delegate security testing to `Hacker` via `new_task`.\n b. Manage the `Hacker`'s findings, including the remediation loop (Hacker -> Coder -> Hacker) detailed in Step 7b.\n6. **Refactoring Step (Optional, Post-Security):** **ONLY AFTER** `Hacker` reports 'Clear' (Step 5 complete):\n a. Check if refactoring is warranted (requested by Planner or identified technical debt).\n b. If yes, delegate to `Refactorer` via `new_task`.\n c. Manage the `Refactorer`'s result.\n d. Consider a brief final `Presenter` check (optional).\n7. **Manage Specialist Results & Loops:**\n a. **On Specialist Success (General):** Receive results via `attempt_completion`. Review. If the solution seems novel/complex/reusable, instruct the specialist (via `ask_followup_question` or expectation) to *consider* adding a lesson. Proceed to the next step in the sequence (Demo -> Secure -> Refactor -> Complete).\n b. **Hacker Loop:** If `Hacker` finds exploits (Step 5), delegate remediation to the appropriate `Coder`. After the fix, re-delegate testing to `Hacker`. Repeat until 'Clear'. Instruct `Hacker` to consider logging lessons after the final 'Clear' report.\n c. **Presenter Loop:** If `Presenter` fails (Step 4), delegate fix to `Coder`. After the fix, re-delegate presentation to `Presenter`. Repeat until success. (Presenter doesn't log; Coder logs fix lessons if applicable).\n d. **On Specialist Failure (General):** If any specialist fails irrecoverably, or remediation loops fail persistently, prepare to report failure to Planner (Step 11). If clarification is needed *from Planner*, pause and report back requesting it.\n8. **Handle Complex Demonstrations:** If a demo task (Step 4a) seems beyond `Presenter`'s basic `execute` capability, identify this early and report back to `Planner` requesting intervention or alternative execution.\n9. **Track Progress & Lessons Learned (Boomerang):** Maintain internal state tracking completion of all steps (functional, demo, security, refactoring). *Before* reporting the final outcome, review your orchestration. If you identified a reusable strategy or pattern *not already documented*, add *your* lesson (Role: Boomerang) to `src/mcp_litellm/docs/lessons_learned.json` (using `read`, parse, append, `write_to_file` via delegated edit or specific MCP tool if available).\n10. **Completion Check:** Verify all required steps for the main task (functional -> demo -> security -> optional refactoring, as applicable) are successfully completed.\n11. **Report Final Outcome to Planner:** Use `attempt_completion` (or appropriate failure signal):\n a. **On Success:** Report overall success, mentioning key stages completed (e.g., \"Task 8.3 successfully completed including demonstration and security checks\").\n b. **On Failure:** Report failure, providing details from the failing specialist/loop and any relevant KB findings (consult `lessons_learned.json` via `read`). If failure requires Planner intervention (unrecoverable issue), state this clearly.",

Objective: Develop an MCP-compatible service (mcp-doc-retriever) using FastAPI, packaged in a Docker container. This service will recursively download website content starting from a given URL, storing files in a mirrored site structure (like wget). It uses requests primarily, with automatic Playwright fallback for detected JS-heavy pages. It avoids re-downloading existing files by path unless forced (--force), handles common errors, and provides a two-phase search capability across the downloaded content: a fast keyword scan on decoded text, followed by precise selector-based text extraction on candidate pages identified via an index file.

Core Components:

  • API Interface: FastAPI server (/download endpoint, /search endpoint, /health).
  • Downloader Engine: Handles recursive fetching, requests/Playwright auto-fallback, --no-clobber (path-based)/--force logic, error handling, saving files in mirror structure, maintaining an index file per download job. Must be asynchronous with concurrency limits.
  • Search Engine: Implements the two-phase search using the download job's index file:
    1. Fast keyword scan on decoded text content of candidate files.
    2. Precise text extraction using BeautifulSoup (CSS selectors) on candidate files.
  • Input/Output Models: Pydantic models (DownloadRequest, DownloadStatus, SearchRequest, SearchResultItem, SearchResponse, IndexRecord).
  • Containerization: Dockerfile (including playwright install) and docker-compose.yml with volume mapping.
  • Packaging: Standard pyproject.toml and uv for dependency management.
  • File Storage:
    • Content: /app/downloads/content/{hostname}/{path}/{filename}.html (mirrored structure).
    • Index: /app/downloads/index/{download_id}.jsonl (maps URLs to local paths, content MD5, status).
  • Documentation: Sparse download of library docs, specific header comments, inline examples, lessons_learned.json.
  • File Size Limit: <= 500 lines per Python file where feasible.

Recovery Plan (If Session Crashes):

  1. Identify Last Completed Task: Review this task plan document ([X] marker).
  2. Identify Next Task: Resume development at the next task marked [ ].
  3. Restart Process: Relaunch the development environment. Ensure Docker (docker compose up -d) is running if needed.
  4. Continue Development: Proceed with the next task.

    • Action: Create src/mcp_doc_retriever/downloader.py. Implement async function fetch_single_url_requests. Takes canonical URL, target local path, force flag. Uses requests. Handles basic connection/HTTP errors. Calculates MD5 hash of content. Saves content to the specified local_path (mirror structure) if --no-clobber check (path existence) passes or force=True. Returns status, content MD5, detected links.
    • Deliverable: downloader.py with fetch_single_url_requests, basic error handling, path-based clobber logic, mirror storage, MD5 calculation.
  • Task 2.2: Implement Recursive Download Orchestration & Indexing
    • Action: Implement main async orchestrator function start_recursive_download. Takes start URL, depth, force flag, download_id. Creates/opens index file (/app/downloads/index/{download_id}.jsonl). Manages queue/set of visited canonical URLs. Calls fetch function (initially fetch_single_url_requests). Extracts links, canonicalizes them, checks domain/subdomain policy, checks depth, checks robots.txt (utils.py helper needed). Appends IndexRecord to index file for each attempt (success/failure). Respects concurrency limits (see Task 2.6).
    • Deliverable: Updated downloader.py with recursive orchestration logic, domain/depth checking, robots.txt checking helper call, index file writing.
  • Task 2.3: Implement Playwright Fallback & Auto-Detection
    • Action: Implement async function fetch_single_url_playwright. Add logic to start_recursive_download (or a wrapper around fetch functions) to: a) Use Playwright if use_playwright=True from API, b) Automatically retry with Playwright if fetch_single_url_requests returns content matching the heuristic (e.g., <1024 chars AND contains <div id="root">/<div id="app"> with little other body). Manage Playwright resources. Update index record on retry/success/failure.
    • Deliverable: Updated downloader.py with fetch_single_url_playwright and automatic fallback logic based on heuristic.
  • Task 2.4: Implement Error Handling & Basic Checks
    • Action: Enhance fetch functions and orchestration logic. Handle timeouts. Implement basic login/paywall check heuristic (scan content for "Login", "Sign In", password fields) and update index record status if detected. Log errors clearly. Ensure fetch status (success, failed_request, failed_robotstxt, failed_paywall, etc.) is recorded in the index file.
    • Deliverable: Enhanced downloader.py with improved error handling and status reporting in index file.
  • Task 2.5: Implement Concurrency Control
    • Action: Integrate asyncio.Semaphore into the recursive download orchestration logic. Use one semaphore for requests calls (limit ~10) and a separate one for Playwright calls (limit ~2-4).
    • Deliverable: Updated downloader.py with semaphore-based concurrency limits.
  • Task 2.6: Create Downloader Test Script
    • Action: Create scripts/test_download.py to test the start_recursive_download function directly. Requires setting up mock responses or pointing to safe local test URLs. Test recursion depth, force/no-clobber, basic Playwright trigger (manual flag), index file creation/content.
    • Deliverable: scripts/test_download.py.

      • Demo showcasing downloader functionality, including recursion, Playwright fallback (manual trigger), and index file creation.

Phase 3: Searcher Implementation

  • Task 3.1: Implement Fast Keyword Scan
    • Action: Create src/mcp_doc_retriever/searcher.py. Implement function scan_files_for_keywords. Takes list of local file paths, list of scan keywords. For each path, opens file, decodes HTML content to text (handle encoding errors gracefully - log/skip), performs case-insensitive keyword search. Returns list of paths that contain all keywords.
    • Deliverable: searcher.py with scan_files_for_keywords function using decoded text.
  • Task 3.2: Implement Precise Selector Extraction (Text Only)
    • Action: Implement function extract_text_with_selector. Takes a single local file path, CSS selector, optional list of extract keywords. Parses HTML with BeautifulSoup. Finds elements matching selector. Extracts text content (.get_text()). If extract keywords provided, filters results keeping only those whose text contains all extract keywords (case-insensitive). Returns list of extracted text snippets.
    • Deliverable: searcher.py with extract_text_with_selector function returning text only.
  • Task 3.3: Integrate Two-Phase Search Logic & Index Lookup
    • Action: Create main search function perform_search. Takes download_id, scan keywords, selector, extract keywords. Reads the index file (/app/downloads/index/{download_id}.jsonl). Filters records for fetch_status='success' to get list of relevant local_path values. Calls scan_files_for_keywords with these paths. Calls extract_text_with_selector for each candidate path returned by the scan. Looks up original_url from the index file for each successful extraction. Structures final results as list of SearchResultItem (containing original_url, extracted_content).
    • Deliverable: Integrated two-phase perform_search logic in searcher.py using index file lookup.
  • Task 3.4: Create Searcher Test Script
    • Action: Create scripts/test_search.py. Requires sample downloaded files and a corresponding sample index file (.jsonl). Test the perform_search function: ensure index is read, scan filters correctly, selector extracts text, results include original URL.
    • Deliverable: scripts/test_search.py.
  • Task 3.5: Phase 3 Verification, Demo & Finalization
    • Goal: Verify the search logic via code review and test script. Demonstrate running test_search.py against sample data, showing index lookup, keyword scan filtering, selector-based text extraction, and correctly mapped original URLs in results. Explain the two-phase flow using the index.

Use FastAPI's BackgroundTasks (or similar async pattern) to run the start_recursive_download function from downloader.py in the background. Pass necessary parameters (URL, depth, force, download_id). Handle immediate errors like invalid start URL format.
    • Deliverable: Functional /download endpoint triggering background download task and returning immediate status.
  • Task 4.2: Integrate Searcher with /search Endpoint
    • Action: Update main.py. Implement /search endpoint. Takes SearchRequest. Checks if index file for download_id exists. Calls perform_search function from searcher.py. Returns SearchResponse containing results or appropriate error (e.g., 404 if index not found).
    • Deliverable: Functional /search endpoint calling search logic.
  • Task 4.3: Create Dockerfile
    • Action: Create Dockerfile.
