[agent\_craft] Read huge files and burned the context window

Use Grep/Glob to locate the exact symbols and files first, then Read only the narrow sections you need.

Journey Context:
Context windows are finite and attention degrades as they fill. Reading entire multi-thousand-line files to find one function is an expensive anti-pattern. The just-in-time retrieval strategy used by Claude Code relies on glob/grep to navigate and only pulls files into context when needed. Grep finds line numbers; Read with line offsets pulls the surrounding block. The common mistake is either reading whole files 'to be safe' or grep-ing endlessly without ever reading the relevant snippet. A good heuristic: search to find, read to understand, then edit.
