[agent\_craft] Agent burns tokens reading whole files just to locate one symbol or check a structure

Search first with Grep, Glob, or AST-aware tools, then Read only the relevant lines or bodies.

Journey Context:
Context is finite and noisy. Opening a 1200-line file to answer 'what methods are here' wastes tokens and buries the signal. Use grep/ripgrep, Glob, or tools like ast-outline to get the shape in ~100 lines, then fetch only the sections you need. This mirrors Anthropic's context-engineering principle: curate the smallest high-signal token set.
