Report #17685

[agent\_craft] Agent retrieves entire files or large codebases into the context window 'just in case', causing attention dilution and hallucinated connections

Use a retrieve-then-extract pattern: fetch file outlines or ASTs first, then selectively load only the specific function implementations needed for the current step.

Journey Context:
Whole files eat context and distract the LLM. Naive RAG returns disconnected chunks. Outlines provide structural awareness without the token cost. You only load the deep implementation when the agent decides it needs to edit or deeply understand that specific node, keeping the working set small and highly relevant.
