cc-millz

Things that make Claude Code even better — my personal marketplace of independent plugins, by Millon15.

Structure inspired by umputun/cc-thingz.

This is an unapologetically opinionated set: every plugin here is something I actually use. Even if you don't need my particular toolbox, it may give you ideas for building your own.

📦 Install

Add the marketplace, then install the plugins you want:

/plugin marketplace add Millon15/cc-millz

/plugin install essentials@cc-millz
/plugin install codex-delegation@cc-millz

• Test locally: run claude --plugin-dir plugins/codex-delegation, and use /reload-plugins in-session to pick up file changes.
• Or pin the plugins in a repo's versioned .claude/settings.json — Claude Code installs everything listed there automatically on the first session in that repository:

{
  "extraKnownMarketplaces": {
    "cc-millz": { "source": { "source": "github", "repo": "Millon15/cc-millz" } }
  },
  "enabledPlugins": { "codex-delegation@cc-millz": true }
}

🔄 Updating

• /plugin → Marketplaces → Update marketplace — the reliable path; pulls the latest catalog from the repository immediately.
• /plugin → Installed → Update now — uses a local cache that can be stale; treat it as a fallback after updating the marketplace.
• Enable auto-update: /plugin → Marketplaces → Enable auto-update refreshes the marketplace catalog on each session start.

🤖 codex-delegation

Uses the Codex CLI as a second-tier workforce: Claude remains the orchestrator and taste owner, while Codex handles bulk work, second opinions, and independent verification.

⚠️ Depends on the codex CLI and the official codex-plugin-cc plugin (/plugin install codex@openai-codex, then /codex:setup).

Official Codex plugin implementations always take precedence: reviews, implementation handoffs, and diagnosis route through the official /codex:review, /codex:adversarial-review, and codex:codex-rescue. This plugin only adds the lanes the official one does not cover.

Core ideas:

• gpt-5.6 (gpt-5.6-sol, the Codex config default) is the top tier — use it for reviews, hard diagnosis, and substantial implementation work.
• gpt-5.5 is the bulk/mechanical tier — clear-spec implementation, data analysis, and migrations.
• Codex output is evidence, not authority — Claude verifies Codex findings against the actual code before relaying them or declaring work done.
• Independent runtime verification — Codex can act as a separate local agent that launches the app, drives the UI in a browser or simulator, captures screenshots, and reports pass/fail with actionable feedback (see codex-computer-use below).

Component	Trigger	Description
skill	codex-delegation:codex-delegate	🧭 Routing brain — maps intent to the right plugin command or agent, carries the model rubric (gpt-5.6 = top tier, gpt-5.5 = bulk), preflight checks, and the verification stance
skill	codex-delegation:codex-workflow-fanout	🔀 Pattern for gpt workers inside Workflow/Agent fan-outs — thin wrapper agents, gpt-5.6: labels, worktree isolation, timeout/background rules
skill	codex-delegation:codex-computer-use	🖥️ Independent UI/runtime verification via codex exec — browser automation, simulators, app launching, screenshots, structured pass/fail/blocked reports
agent	codex-workflow-worker	📦 Spawnable thin wrapper — one self-contained Codex task per spawn; returns the report and never solves the task itself
