The HEARTBEAT_OK_TOKEN comparison was broken because the token
itself ("HEARTBEAT_OK" with underscore) was being compared against
a response string that had underscores removed. This made the
condition always fail, preventing the heartbeat service from
recognizing "no tasks" responses.
Now both sides of the comparison remove underscores consistently,
allowing proper matching of the HEARTBEAT_OK token.
Add URL validation and redirect limits to web_fetch tool to prevent potential security issues:
- Add _validate_url() function to validate URLs before fetching
- Only allow http:// and https:// schemes (prevent file://, ftp://, etc.)
- Verify URL has valid scheme and domain
- Return descriptive error messages for invalid URLs
- Limit HTTP redirects to 5 (down from default 20) to prevent DoS attacks
- Add MAX_REDIRECTS constant for easy configuration
- Explicitly configure httpx.AsyncClient with max_redirects parameter
- Improve error handling with JSON error responses for validation failures
This addresses security concerns identified in code review where web_fetch
had no URL validation or redirect limits, potentially allowing:
- Unsafe URL schemes (file://, etc.)
- Redirect-based DoS attacks
- Invalid URL formats causing unclear errors
Skip API key validation for bedrock/ model prefix since AWS Bedrock
uses IAM credentials instead of API keys.
