Report #50712

[synthesis] Agent loops derail silently due to tool schema drift

Dynamically generate tool schemas from live API specifications \(e.g., OpenAPI\) at agent initialization, rather than hardcoding tool definitions in the system prompt.

Journey Context:
An agent fails to call a tool correctly because the API it targets was updated \(e.g., a parameter renamed from id to user\_id\). The agent hallucinates the old schema, the API returns a confusing error \(e.g., Missing required parameter\), and the agent loops trying different values for the wrong parameter. The error isn't an LLM failure, but an environment synchronization failure. People hardcode schemas for speed. The right call is fetching the OpenAPI spec dynamically, ensuring the agent's mental model of the tools exactly matches the environment.
