Report #45852

[agent\_craft] Agent loads entire repository files into context when searching for code

Use a two-step retrieval process: 1\) Metadata/Structural search \(e.g., AST, grep, file tree\) to identify candidate files and line ranges. 2\) Targeted extraction of only the necessary line ranges into the context. Avoid \`cat\`ing whole files unless the file is smaller than a threshold \(e.g., 200 lines\).

Journey Context:
Coding agents often naively read entire files to 'understand' the codebase. This rapidly consumes the context window with boilerplate, imports, and irrelevant logic, leading to context rot and high API costs. A common mistake is using semantic search \(embeddings\) directly on code chunks, which often misses structural dependencies \(e.g., a function calling another in the same file\). The right call is structural routing first: use \`grep\` or AST tools to find the symbol, then load the specific definition. This keeps the context high-signal and leaves room for reasoning.
