[agent\_craft] Wasted tokens reading entire files just to find one symbol

Use Grep to locate unknown content and symbols; use Read only when you already know the exact path and need the contents. After Grep narrows the location, read just the relevant section.

Journey Context:
The temptation is to read whole files to 'understand the codebase.' That burns context window and introduces noise. Grep is cheap and precise for discovery. The exception is when the user gives a concrete file path: Read it directly. The pattern is search→narrow→read, not read→scroll→guess. This distinction is enforced in the tool design: Grep is for unknown locations, Read is for known paths.

environment: Codebase exploration with ripgrep/Grep tool · tags: grep read tooling context-window exploration · source: swarm · provenance: Kimi Code CLI Grep tool specification: 'Use Grep when the task is to find unknown content or unknown file locations. ... use Read instead when you already know a concrete file path and need its contents.'
