Report #71377

[synthesis] Agent calls deprecated or incorrect API endpoints due to outdated tool descriptions

Dynamically generate tool schemas from live API specifications \(e.g., OpenAPI/Swagger\) at runtime rather than hardcoding tool descriptions in the codebase.

Journey Context:
Developers define tool schemas \(descriptions, parameters\) in the agent's code. Over time, the actual API evolves \(endpoints change, parameters are deprecated\), but the agent's schema remains static. The agent confidently calls the old API, gets 404s or silent failures, and attempts bizarre workarounds. The root cause isn't the agent's reasoning, but the stale interface contract. The fix shifts the burden from prompt engineering to infrastructure, ensuring the agent always reads the latest API spec, treating the spec as the source of truth.
