Report #366

[agent\_craft] Read entire files into context and ran out of tokens

Use grep/ripgrep/Glob to locate symbols first, then read only the surrounding lines or specific functions; reserve full-file reads for small, stable files like configs or AGENTS.md.

Journey Context:
Read operations dominate agent token budgets \(empirically ~70-76% in SWE-Pruner traces\). Greedy full-file reads are easy to write but quickly exhaust context windows and drown the model in irrelevant lines. The efficient pattern is coarse-to-fine: grep for the symbol, read the matched region, then expand only if needed. This mirrors how human developers skim. The risk is missing cross-file dependencies, so after narrowing, follow import/usage edges selectively.
