setup

A setup command that checks whether the local Codex command-line tool is installed and ready, with an optional stop-time review setting.

In plain words
What is it for?
Checking Codex installation and login readiness, installing Codex through npm, and reviewing the final setup status.
Why use it?
It shows what is missing before you try to use Codex and can guide you through installing it when npm is available.

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.

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 yesterday.

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

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.mjs" setup --json $ARGUMENTS

If the result says Codex is unavailable and npm is available:

  • Use AskUserQuestion exactly once to ask whether Claude should install Codex now.
  • Put the install option first and suffix it with (Recommended).
  • Use these two options:
    • Install Codex (Recommended)
    • Skip for now
  • If the user chooses install, run:
npm install -g @openai/codex
  • Then rerun:
node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.mjs" setup --json $ARGUMENTS

If Codex is already installed or npm is unavailable:

  • Do not ask about installation.

Output rules:

  • Present the final setup output to the user.
  • If installation was skipped, present the original setup output.
  • If Codex is installed but not authenticated, preserve the guidance to run !codex login.

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.
