* feat: add size caps for PR diff, fetch_url, Slack threads, pagination, message queue Per-source byte/token caps with explicit truncation markers to prevent unbounded payloads from blowing up LLM context/memory. - reviewer_diff.py: cap PR diff at 200K chars with head+tail truncation - fetch_url.py: cap markdownify output at 100K chars - slack.py: cap thread message fetch at 500 messages - github_comments.py: cap _fetch_paginated at 50 pages - thread_ops.py: cap queued messages at 100 (drop oldest) Closes OPE-51 Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com> * fix: compute diff line set from full diff, keep most recent Slack messages Address PR review comments: 1. Truncated diffs rejected valid findings: fetch_pr_diff now returns the full diff; truncate_diff is called separately in reviewer.py so the line set used for add_finding/publish_review validation is computed from the complete diff, not the truncated prompt text. 2. Slack cap dropped recent thread context: fetch_slack_thread_messages now keeps the most recent SLACK_THREAD_MAX_MESSAGES messages (was keeping the oldest). The tool surfaces a truncation marker in the formatted output so the LLM knows the thread was truncated.

"""Fetch content from a URL and convert HTML to markdown format.
|
|
|
|
This tool fetches web page content and converts it to clean markdown text,
|
|
making it easy to read and process HTML content. After receiving the markdown,
|
|
you MUST synthesize the information into a natural, helpful response for the user.
|
|
|
|
Args:
|
|
url: The URL to fetch (must be a valid HTTP/HTTPS URL)
|
|
timeout: Request timeout in seconds (default: 30)
|
|
|
|
Returns:
|
|
Dictionary containing:
|
|
- success: Whether the request succeeded
|
|
- url: The final URL after redirects
|
|
- markdown_content: The page content converted to markdown
|
|
- status_code: HTTP status code
|
|
- content_length: Length of the markdown content in characters
|
|
|
|
IMPORTANT: After using this tool:
|
|
1. Read through the markdown content
|
|
2. Extract relevant information that answers the user's question
|
|
3. Synthesize this into a clear, natural language response
|
|
4. NEVER show the raw markdown to the user unless specifically requested
