Report #61126

[agent\_craft] Providing entire codebase to context window exceeds limits; providing single file loses cross-file dependencies

Use 'Dependency-Aware Context Packing': When the agent needs to edit code, retrieve the target file \(full text\) plus a 'dependency skeleton' of related files \(imports, function signatures, type definitions only, not implementations\). Use static analysis \(tree-sitter\) to extract imports and build a dependency graph. Pack the target file verbatim \(working memory\) \+ dependency skeletons \(associative memory\) \+ recent git diff \(temporal context\).

Journey Context:
Naive RAG retrieves semantically similar chunks, which often misses critical dependencies \(e.g., editing a function without seeing the interface it implements\). Full file context is too long. The solution mimics human development: you have the file you're editing open \(full view\), you have headers/imports of related files open in tabs \(skeleton\), and you remember what you just changed \(git diff\). Static analysis \(tree-sitter, LSP\) extracts precise dependencies without hallucination. This is more token-efficient than embedding-based retrieval for code editing because code structure is discrete, not semantic. The dependency skeleton approach typically reduces context from 10k tokens \(full files\) to 800 tokens \(skeletons \+ target file\).
