Report #16609

[agent\_craft] Injecting entire API documentation or large markdown files into the system prompt

Use a RAG pipeline to retrieve only the specific API signatures and examples relevant to the current sub-task, keeping the system prompt strictly to behavioral guidelines.

Journey Context:
It's tempting to put the whole React or FastAPI docs in the system prompt. But this eats 50k\+ tokens, dilutes attention, and costs a fortune. RAG fetches exactly what's needed. Tradeoff: RAG might miss implicit constraints, so you must include a fallback tool that allows the agent to explicitly search the docs if RAG results are insufficient for the specific implementation.
