Maintainer-only vendor submodule updater: audits every submodule under vendor/ against upstream, shows commits and files behind, then updates the picked ones one at a time with audit checks and one commit each. Use when asked to update vendors, refresh submodules or check vendor drift.

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-upgrade — Vendor submodule updater

**CC Commander** · /ccc-upgrade · audit vendor/ → pick → update, check, commit one at a time

## When to use / when not to

- Use inside the Commander repository to audit and update the submodules under `vendor/`. Trigger phrases: "update vendors", "refresh submodules", "pull latest vendor changes", "sync the ecosystem", "are any vendors out of date", "check vendor drift".
- Not for updating the installed Commander plugin: that is `/ccc-update`, an end-user tool with a similar name.
- Not a read-only diagnostic like `/ccc-doctor`: this skill writes local commits, one per submodule, after the user picks.
- Arguments: `--check` audits only (fetch, table, stop); `--all` skips the picker and updates every submodule with an update available.
- The scheduled workflow `.github/workflows/vendor-update.yml` runs the same audit unattended; this skill is the human-in-the-loop variant.
- In Codex, ask each picker as a plain-text question with the same options.

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-upgrade@sha256:5a6f2c0c978f58a7

The line at the top of this page pins the label git:20261025.7eae921, 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.
