[agent\_craft] Context window overflow when sending large codebases to the agent

Send a 'skeleton' of the repo \(file paths \+ signatures\) for all files, then append full content only for the top-K most relevant functions/classes retrieved via embedding similarity or call-graph analysis.

Journey Context:
Naive RAG retrieves whole files, but a single large file can exhaust the 128k window. The 'skeleton \+ snippets' approach preserves global structural awareness \(agents need to know 'where' things are\) without paying the token cost for irrelevant boilerplate. We compared this against full-file RAG and saw 40% higher task completion on repo-wide refactoring tasks because the agent maintained visibility of cross-file dependencies while keeping working code in-context. The tradeoff is increased latency for the retrieval step, which is acceptable for coding tasks but not for chat.
