📝 WalkthroughWalkthroughChangesThe pull request adds Reserp Search Tool
Merge Risk: 🟡 Moderate · up to The new search tool can block indefinitely when the external service does not respond, and malformed public URLs can still be forwarded to that service. Merge should wait for a finite timeout and explicit handling of the documented URL contract, or for those risks to be explicitly accepted. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Reserp API request: require an HTTPS URL for www.google.com with the /search
path, a non-empty q query parameter, no num parameter, and a maximum length of
10,000 characters. Add invalid-input tests verifying validation fails and
requests.post is not called.

Apply a finite HTTP timeout.
requests.post has no timeout. CrewAI can run _run in an executor, but cancelling the surrounding operation does not stop the blocked worker. Add a finite, configurable timeout to the Reserp request.

Summary
The tool intentionally leaves retries, timeout policy, task queues, concurrency, caching, and pagination to the surrounding CrewAI application. Reserp is exposed as a primitive rather than an orchestration layer.
