Report #83888

[agent\_craft] Agent exhausts context window with full file contents or loses track of symbols across large codebases

Generate a repository map using tree-sitter to extract class/function signatures and file dependencies, then pack only relevant signatures in context while fetching full content only for files being actively edited via lazy loading.

Journey Context:
Full-file context hits token limits at ~50k lines; naive truncation loses critical cross-file references. The repo-map approach \(as implemented in Aider\) encodes the graph structure of the codebase using only signatures \(names, types, line ranges\), yielding 10x compression. This mirrors human developer behavior: keeping headers/symbols in working memory while fetching implementation details on demand. The tradeoff is that the agent must make an extra tool call to fetch full file content when editing, but this saves 70% of context tokens in large repositories.
