Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00049 | $0.00953 |
| Opus 5 | $0.00024 | $0.00477 |
| Sonnet 5 | $0.00010 | $0.00191 |
| Haiku 4.5 | $0.00005 | $0.00095 |
Grade A, and why
setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

setup is a skill published in the GitHub repository WillInvest/ClaudeX (4 stars, last pushed 3mo ago), licensed MIT. It adds 49 tokens to every session and 953 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
