Report #90885

[agent\_craft] Including full file contents for context exceeds token limits and dilutes attention on relevant functions

Construct a two-tier context: use tree-sitter to generate signature-only stubs \(definitions \+ docstrings\) for all files in the workspace, and inline the full implementation only for the specific function under edit and its direct callees. Wrap each in tags.

Journey Context:
Naive RAG retrieves files based on embedding similarity, often returning large boilerplate files. AST-based stubbing reduces tokens by 90%\+ while preserving structural context \(imports, class hierarchies\). The model only needs full text for the 'hot' code being modified; everything else is context for name resolution. This pattern is essential for repo-level agents.
