/ccc-upgrade — Vendor Submodule Updater

⚠️ Run only from the CC Commander repo root. Verify pwd ends in /cc-commander (or your fork's name) and ls .claude-plugin/marketplace.json succeeds. Running this skill in the wrong cwd would touch unrelated submodules.

Interactive workflow that audits the 19+ vendor submodules under vendor/, surfaces what changed upstream, lets the user pick which to update via AskUserQuestion, then runs the update + test + commit cycle one submodule at a time.

Similar in spirit to /ccc-doctor (read-only diagnostic) — this one writes (commits per submodule) but only after explicit user approval.

When to fire

User types /ccc-upgrade, or says any of:

• "update vendors"
• "refresh submodules"
• "pull latest vendor changes"
• "sync the ecosystem"
• "are any vendors out of date"
• "check vendor drift"
