Update the installed CC Commander plugin: detect the install mode and installed vs latest version, hand over the exact update commands, then verify the installed runtime and hooks after restart. Use when the user asks to update Commander or suspects an outdated install.

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-update — Get onto the latest

**CC Commander** · $ccc-update · Detect → update → restart → verify

## When to use / when not to

- Use to move an installed Commander plugin to the latest published version.
- Use after a restart to confirm an update landed.
- Not for vendor submodules under this repository (maintainer-only): that is `$ccc-upgrade`.
- Not for a full health report: `$ccc-doctor` also flags staleness, as one row of a larger diagnostic.

In Codex, ask plain-text questions where this skill says AskUserQuestion, and use the Codex path in [references/install-modes.md](references/install-modes.md#codex).

## What happens

### Step 1 — Detect install mode and versions

Run:

```bash
CLONE="$HOME/.claude/plugins/marketplaces/commander-hub"
if [ ! -d "$CLONE" ]; then
  CLONE=$(node -e "
    try {
      const d=JSON.parse(require('fs').readFileSync(process.env.HOME+'/.claude/plugins/known_marketplaces.json','utf8'));
      const m=d['commander-hub'];
      if(m&&m.installLocation) process.stdout.write(m.installLocation);
    } catch(e) {}
  " 2>/dev/null || echo "")
fi
[ -z "$CLONE" ] && CLONE="n/a"
[ "$CLONE" != "n/a" ] && [ ! -d "$CLONE" ] && CLONE="n/a"

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-update@sha256:5bb1db42870d32fa

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.
