Report #95115

[agent\_craft] Agent pulls entire files into context to answer localized questions, causing overflow and distraction

Implement AST-based chunking or line-range retrieval. Fetch the target function/class and its immediate dependencies, plus the signature of the caller, rather than the whole file.

Journey Context:
Agents often default to reading whole files because it is the easiest tool to implement. A 1000-line file fills context and dilutes signal. AST-based retrieval \(using tree-sitter or LSP\) provides exactly the relevant code block, saving context space for reasoning. The tradeoff is building the parser, but it pays off in reduced token usage and higher accuracy by avoiding distraction from irrelevant code.
