Contributor first-hour plan for the current repository: reads CLAUDE.md, BIBLE.md and package.json, checks required tools, asks the contributor's role, and returns a five-step checklist plus five real starter resources. Use when someone new joins a repo or types /ccc-onboard.

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-onboard — contributor first hour

**CC Commander** · /ccc-onboard · role → first task → a verified first hour

Build the guide from the repository's own instructions and scripts, never from a generic open-source checklist. The skill is read-only: it inspects files and tool versions and returns a plan; it installs, edits and commits nothing.

On Codex, AskUserQuestion becomes a plain-text question with the same options, and WebFetch becomes a `curl -sI` reachability check.

## When to use / when not to

- Use when a contributor is new to a repository (any repository, including Commander's own) and needs a practical first hour.
- Use `/ccc-start` for first-run Commander onboarding, `/ccc-adopt` to add Commander conventions to a project's CLAUDE.md, and `/ccc-xray` for a project health scorecard.

## What happens

### 1. Brand header

```markdown
**CC Commander** · /ccc-onboard · Contributor first hour
```

### 2. Repo context

Read only the files that exist, in this order:

- `CLAUDE.md` — local conventions, required tools, test commands, workflow rules
- `BIBLE.md` — product architecture, domain language, non-negotiable project rules
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-onboard@sha256:34e46115b44a0594

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.
