Audit and safely optimize the local Commander setup: version freshness, junk, count drift, superseded agents, hooks, settings keys, MCP staleness and cost settings. Read-only scan first; backs up, archives (never deletes) and asks before any fix. Use when the setup feels cluttered, stale or slow.

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

# $ccc-tuneup — Safe local setup optimizer

**CC Commander** · $ccc-tuneup · read-only scan → scorecard → confirm → backup, archive, fix → verify

## When to use / when not to

- Use to clean and tune a local install: archive junk, add missing structural settings keys, retire superseded local agents, fix count drift in a maintainer checkout, and surface cost settings.
- `$ccc-doctor` diagnoses and stays read-only; this skill remediates, with backups and a confirm step. Use `$ccc-update` to change the plugin version and `$ccc-settings` to change preferences.
- Arguments:
  - `--check` — audit and scorecard only. No picker, no mutation. Default when the user seems unsure.
  - `--fix` — audit, then offer safe fixes; opt-in cleanups start unselected.
  - `--aggressive` — like `--fix`, with session archival and superseded-agent retirement pre-selected.
  - no argument — audit, scorecard, then the fix picker.
- In Codex, ask each picker as a plain-text question with the same options; skip the Desktop-only `spawn_task` suggestion.

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-tuneup@sha256:836b6f5a28f3f791

The line at the top of this page pins the label git:20261013.fbe187d, 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.
