Token cost

What it costs to keep this loaded

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.

Security

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 7d 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.

Origin

This is a copy

100% identical to setup — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Check each prerequisite and report it as ✅ or ❌ with the exact fix command:

  1. Codex CLI installedcodex --version (fix: npm i -g @openai/codex)
  2. Codex authenticatedcodex login status or the equivalent for the installed version (fix: codex login)
  3. Inside a git repogit rev-parse --is-inside-work-tree. Distinguish the two failure modes: git not installed (fix: xcode-select --install on macOS, apt install git/winget install Git.Git elsewhere) vs. not a repository (fix: git init — ClauDex reviews diffs, so it needs one)
  4. Optional: the official Codex plugin for /codex:* commands (/plugin marketplace add openai/codex-plugin-cc, then /plugin install codex@openai-codex)

When everything passes, reply: "ClauDex is ready. Claude writes, Codex reviews, you ship. 🧡🖤 First time? Run /claudex:demo — two minutes, zero risk: watch the two models argue over planted bugs before you point them at real code."

If the Codex CLI or its login is missing, end with: "It takes two to ClauDex. 🧡 Claude is here — 🖤 Codex is not. Run the fix commands above, then /claudex:setup again for the duet."

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.
