Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 5.1 | $0.00017 | $0.00279 |
| Opus 5.5 | $0.00007 | $0.00112 |
| Sonnet 5.5 | $0.00003 | $0.00056 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to setup — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Run:
node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.mjs" setup --json $ARGUMENTS
If the result says Codex is unavailable and npm is available:
- Use
AskUserQuestionexactly once to ask whether Claude should install Codex now. - Put the install option first and suffix it with
(Recommended). - Use these two options:
Install Codex (Recommended)Skip for now
- If the user chooses install, run:
npm install -g @openai/codex
- Then rerun:
node "${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.

setup is a command published in the GitHub repository zebbern/agent-collab (34 stars, last pushed 16d ago), licensed Apache-2.0. It adds 17 tokens to every session and 279 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
