Token-budget discipline for long sessions - context size, session limits, compaction, handoff, tier and gear routing.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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
   test runs go to a subagent: the built-in `Explore` agent for finding code, a
   general-purpose one (Sonnet is enough) for mechanical edits and test runs. Its
   context is discarded when it returns; yours is re-read every turn.
5. **Hand off when the user asks.** Do it at a boundary, not mid-task, with `/wrap`.
   When the user wants to continue in a fresh session, prepare and verify a handoff. Ask them to run `/clear` afterward.
   Runtime hooks separately control any configured compaction interruption.

How to install

The exact contents, by fingerprint
mdr add yahyalendani/opus-tuner-claude-skill/opus-tuner@sha256:0037fbcfdfdb8478

The line at the top of this page pins the label git:20261101.4a49f38, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
