# opus-tuner

Every request re-reads the whole context, so these rules are about how much gets
re-read and how many requests read it.

## The five rules

1. **Batch independent tool calls.** Four greps in one message read the context
   once; four separate messages read it four times.
2. **Grep before read, and bound every read.** `Read` with no `limit`, or above 400
   lines, only when you are certain. Otherwise `offset`/`limit`, or search first.
   Never recursive-scan a repo to find one symbol.
3. **Never trade verification for tokens.** A "saving" that causes rework is a loss.
4. **Delegate breadth, not judgement.** Exploration, mechanical multi-file edits and
