Pre-release assessment that fans out via /ccc-fleet into up to three isolated workers (QA audit, unit tests, Playwright E2E) running /ccc-testing lanes, then writes a severity-ranked PASS or FAIL verdict. Use when about to tag a release, after a large merge, or asking is this ready.

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-e2e — Full-surface confidence before shipping

**CC Commander** · /ccc-e2e · parallel QA, unit and E2E workers, one honest verdict

Composes `/ccc-fleet` (parallel dispatch, worktree isolation) with `/ccc-testing` (testing lanes). Audit only: workers find and report, they do not fix.

## When to use / when not to

- Use before tagging a major or minor release, after merging a feature that touches five or more files, after a cross-module refactor, or when the user feels coverage is thin but cannot say where.
- Quick bug-fix patch: `/ccc-review`. Single-file change: `/ccc-testing`. Docs-only change: skip. Hotfix under time pressure: `/ccc-ship` pre-flight.
- Codex: ask pickers as plain-text questions and run each worker as `codex exec --json --sandbox workspace-write` in its own `git worktree`; the session tools below are skipped.

## What happens

### 1. Context strip

Run in parallel, silent on failure:

```bash
git rev-parse --abbrev-ref HEAD
BASE=$(git symbolic-ref --short refs/remotes/origin/HEAD 2>/dev/null | sed 's#^origin/##'); BASE=${BASE:-main}
git rev-list --count "$BASE"..HEAD 2>/dev/null
git diff --shortstat "$BASE"..HEAD 2>/dev/null
…

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-e2e@sha256:06af90916ef4849e

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.
