Scaffold a new web app, API or CLI from a three-question spec, built by a background agent and verified. Use to start a new project or app.

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-build — scaffold, verify, hand over

**CC Commander** · /ccc-build · a template pick, three spec questions, a background scaffold and a lead-verified result.

The lead session is the control plane: it interviews, dispatches and verifies. A background agent does the multi-file writing (`rules/workflow-first.md`). The user's selected model is preserved for the lead; only the scaffold agent is routed to `sonnet`.

Codex: ask each picker as a plain-text question, run the scaffold inline or with `codex exec --json`, and skip session markers.

## When to use / when not to

- Use for a new web app, API, CLI, or an idea that needs a spec before code.
- Use `/ccc-mobile` for mobile apps and `/ccc-plan` for a feature inside an existing codebase; this skill routes there.
- Use `/ccc-design` for a landing page or UI polish on an existing project.

## Arguments

| Invocation | Behavior |
|---|---|
| `/ccc-build` | Context strip, template picker, full flow |
| `/ccc-build web-app` / `api` / `cli` | Skip the picker, start at Q1 |
| `/ccc-build mobile` | Invoke the `ccc-mobile` skill; do not scaffold here |
| `/ccc-build spec` | Invoke the `ccc-plan` skill |

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-build@sha256:7f5f939d89f4d97f

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.
