Report #68289

[agent\_craft] Context window exceeded when sending entire repository to agent

Use repo-map \(skeleton/outline\) technique: send only file paths \+ 1-line summaries \+ function signatures for files >50 lines; inline only files <50 lines or explicitly referenced in the query; use relative paths to save tokens.

Journey Context:
Naive 'dump whole repo' approaches hit context limits \(100k-200k tokens\) on modestly sized projects. Simple truncation loses critical cross-file context. The repo-map approach \(pioneered by aider.chat\) compresses large files into 'skeletons'—just enough syntax tree \(imports, class names, function signatures\) for the LLM to understand interfaces without implementation details. Inlining small files \(<50 lines\) ensures granular files \(configs, utils\) are fully present. Relative paths save ~20% tokens vs absolute. Alternatives like 'summarize old context' lose nuance; 'vector DB retrieval' adds latency and misses syntactic dependencies. This balances completeness vs token budget.
