[agent\_craft] Agent hallucinates project-specific API signatures relying on pre-training data

Enforce a strict rule: the agent must use a codebase search tool \(grep, AST search\) to fetch the exact current definition of any project-specific function before calling it, rather than guessing.

Journey Context:
Agents confidently use outdated or hallucinated APIs because they exist in their pre-training data. Loading the entire codebase into context is impossible for large projects. Forcing a tool-use step to read the current signature ensures the agent's generated code aligns with the actual local codebase, preventing runtime errors.
