Use when the user runs /claudex:setup or asks to install/bootstrap claudex's dependencies (the Codex plugin and superpowers). Installs both plugins, then verifies the Codex CLI via codex:setup.

claudex:setup — bootstrap claudex's dependencies

claudex's /claudex:think needs two other plugins: the Codex plugin (openai/codex-plugin-cc, for the Codex runtime) and superpowers (anthropics/claude-plugins-official, for the brainstorming flow). This skill installs both, then runs the Codex CLI check.

This skill depends only on the claude CLI and Bash, so it works even before either dependency exists. Every step is idempotent — re-running /claudex:setup is safe and resumes cleanly.

Order (important)

Install both plugins first, so the user reloads once — only then is codex:setup invokable, and you run it last.

1. install codex plugin   (CLI, no reload needed yet)
2. install superpowers     (CLI, no reload needed yet)
3. ONE reload gate         (user runs /reload-plugins → both go live)
4. invoke codex:setup      (now available; verifies the Codex CLI)

Steps

1. Install the Codex plugin

Check first, then add the marketplace and install only if missing:

claude plugin marketplace list 2>/dev/null | grep -q openai-codex \
  || claude plugin marketplace add openai/codex-plugin-cc
claude plugin list 2>/dev/null | grep -q 'codex@' \
  || claude plugin install codex@openai-codex

2. Install superpowers

claude plugin marketplace list 2>/dev/null | grep -q claude-plugins-official \
  || claude plugin marketplace add anthropics/claude-plugins-official
claude plugin list 2>/dev/null | grep -q 'superpowers@' \
  || claude plugin install superpowers@claude-plugins-official

If a marketplace add fails (e.g. no network), report it and stop — the install in that step can't succeed. The two plugins are independent, so a failure on one doesn't invalidate the other.

3. Reload gate (one time)

Plugins installed via the CLI are not live in the running session — their skills (like codex:setup) aren't invokable until a reload. Check whether codex:setup is available to you now:

Not available → tell the user: "Codex and superpowers are installed. Run /reload-plugins (or restart Claude Code) once, then re-run /claudex:setup to finish — it'll skip the already-installed plugins and run the Codex CLI check." Then stop. The idempotent checks in steps 1–2 make the re-run cheap.
Available → continue to step 4.

4. Verify the Codex CLI

Invoke codex:setup (via the Skill tool). It checks the local Codex CLI, offers to npm install -g @openai/codex if missing, and prints !codex login guidance if the CLI is installed but not authenticated. Present its output to the user.

5. Confirm

Run claude plugin list and confirm claudex, codex, and superpowers are all enabled. Report the final state. /claudex:think is now ready to use.

Notes

Scope: installs default to user scope. Pass --scope project to the install commands if the user wants the deps tied to this project instead.
Already set up: if all three plugins are enabled on the first run, skip straight to step 4 (the Codex CLI check) and report that nothing needed installing.
Don't write to ~/.claude directly to fake plugin state — let the CLI manage it.
