A setup command that checks whether the local Codex command-line tool is ready to use and can enable an optional review check when work stops. It can also point out missing sign-in, provider settings, or workspace configuration.

Use it to check installation and authentication, enable the stop-time review gate, configure workspace role defaults, verify status, or inspect runtime and saved-state problems with the related doctor command.

It helps identify setup problems before you rely on Codex in a workspace. When Codex is unavailable, it can guide the user through deciding whether to install it.

setup — Command for Claude Code by vsladkov/claudex-stereo

Install

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.

Claude Code

/plugin marketplace add vsladkov/claudex-stereo

Claude Code

/plugin install stereo

Made for: Claude Code.

Or install stereo, the plugin that ships this one along with the rest of its 4 skills, 15 commands, 1 agent, 3 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00019	$0.00678
Opus 5.5	$0.00008	$0.00271
Sonnet 5.5	$0.00004	$0.00136
Haiku 4.5	$0.00002	$0.00068

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 21d 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.

What it actually says

Happy path:

Install the Stereo plugin.
When the report's - auth: line is not ready, run !codex login; use !codex login --device-auth or !codex login --with-api-key when the report names those fallbacks.
When the - claude: or - claude auth: line is not ready, follow its next step: install or update Claude Code to the version the report names, or run claude auth login.
Configure optional third-party provider keys only when the report lists unconfigured aliases or missing provider environment variables.
Optionally run /stereo:setup --enable-review-gate when - review gate: is disabled.
Optionally run /stereo:config to set workspace role defaults when - role defaults: says none are configured.
Verify the workspace with /stereo:status after the - codex:, - auth:, - claude:, and - claude auth: checks are ready.

Use /stereo:doctor when install readiness is healthy but workspace runtime or durable state needs inspection.

Raw slash-command arguments: $ARGUMENTS

Parse them before running anything: the only accepted flags are --enable-review-gate and --disable-review-gate, at most one of them. Reject any other token, and both flags together, naming the two accepted flags. <setupFlags> is the accepted flag as its own argument, or nothing; never pass the raw arguments through the shell. Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.ts" setup --json <setupFlags>

If the payload's codex.available is false and npm.available is true:

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.ts" setup --json <setupFlags>

If Codex is already installed or npm is unavailable:

Do not ask about installation.

Output rules:

Print the payload's rendered field verbatim — the complete # Stereo Setup report — and relay its next steps as written, including every exact path, environment-variable name, and !codex login fallback. Never reconstruct, paraphrase, or reorder it.
If installation was skipped, print the original run's rendered report.

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.

It adds 19 tokens to every session and 678 once invoked, about $0.0001 per session on Opus 5.5. 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.
