[agent\_craft] Agent hallucinates API endpoints or database columns when interacting with external systems

Inject the exact OpenAPI spec or database schema \(DDL\) for the relevant endpoints/tables into the context immediately before the agent attempts to use them, rather than relying on the agent's parametric memory.

Journey Context:
LLMs have broad but shallow knowledge of APIs and DBs. They will confidently hallucinate endpoints, parameter names, or column types that don't exist, leading to frustrating retry loops. Parametric memory is static and potentially outdated. Providing the machine-readable schema as runtime context grounds the agent in reality. To save tokens, only inject the schema for the specific resources the agent has decided to use, not the entire API catalog.
