Selective ECC loader: pick one Everything Claude Code skill, agent or hook from the vendored checkout and symlink or copy only that component into ~/.claude, with a backup, never the full harness. Use when the user wants a single ECC component without installing ECC.

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-ecc — one ECC component, nothing else

**CC Commander** · /ccc-ecc · installs a single Everything Claude Code (ECC) skill, agent or hook into `~/.claude/` from the pinned vendor checkout.

## When to use / when not to

- Use when the user wants one ECC skill, agent or hook (for example a reviewer agent or a single hook script) without ECC's installer, settings, commands or rules.
- Do not use to install or update the whole ECC harness, to change `settings.json`, or to edit ECC itself. For refreshing vendor checkouts use `/ccc-upgrade`.

ECC is vendored as a git submodule at `vendor/everything-claude-code/` (upstream `affaan-m/everything-claude-code`). Its components live in `skills/<name>/SKILL.md`, `agents/<name>.md` and `scripts/hooks/<name>.js` (hook wiring is declared in its `hooks/hooks.json`).

## What happens

1. **Locate ECC.** From a CC Commander checkout:

   ```bash
   ROOT="$(git rev-parse --show-toplevel 2>/dev/null)"
   for c in "$ROOT/vendor/everything-claude-code" "${CLAUDE_PLUGIN_ROOT}/../../vendor/everything-claude-code"; do
     [ -d "$c/skills" ] && { ECC="$(cd "$c" && pwd)"; break; }
   done
   echo "${ECC:-missing}"
   ```

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-ecc@sha256:65561ad46fff5a26

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.
