Alias for $ccc-learn: opens the domain picker to browse and load a skill domain such as design, marketing, SaaS, testing, DevOps or security. Use when the user types $ccc-domains, says 'domain skills' or 'show categories', or asks which skills exist for a field.
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-domains — alias for $ccc-learn
**CC Commander** · $ccc-domains · the same domain picker as `$ccc-learn`, kept so older references keep working.
`$ccc-learn` is the canonical domain picker. This alias holds no menu of its own, so the two never drift.
## When to use / when not to
- Use when someone types `$ccc-domains` or follows an older link or doc that names it.
- Prefer `$ccc-learn` in anything new you write or suggest.
- Do not use for the full skill and agent catalog: that is `$ccc-browse`.
## What happens
1. Invoke the `ccc-learn` skill with the Skill tool, passing `$ARGUMENTS` unchanged (for example `$ccc-domains seo` becomes `ccc-learn seo`).
2. Say one line first: "`$ccc-domains` is an alias — opening `$ccc-learn`."
3. Skill tool unavailable (Codex or an older client): Read `${CLAUDE_PLUGIN_ROOT}/skills/ccc-learn/SKILL.md` and follow it from its first step with the same argument.
## Done when
- `ccc-learn` was invoked, or its SKILL.md was read and followed, in this turn with the user's argument intact.
## Guardrails
- Never render a separate domain menu here; `$ccc-learn` owns the picker and its choices in `${CLAUDE_PLUGIN_ROOT}/menus/ccc-learn.json`.

How to install
mdr add kevinzai/commander/ccc-domains@sha256:44d2dafec31bec67The 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.
