setup

setup is a skill for Claude Code, Codex from IgorGanapolsky/ThumbGate. It costs 34 tokens per session (130 once invoked), scanned A, original, MIT.

A setup check for the Codex bridge inside Claude Code. It checks whether Codex review is available and whether related bridge files and configuration are present.

In plain words
What is it for?
It is for checking the Codex installation, the codex exec review command, the bridge artifact directory, and the bundled ThumbGate server configuration.
Why use it?
It shows whether the bridge is ready before someone relies on Codex review from Claude Code.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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 5d 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

Setup

Use this skill only when the user explicitly wants to verify the bridge.

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-bridge.js" setup

Then explain:

  • whether codex is installed
  • whether codex exec review is available
  • where the persistent bridge artifact directory lives
  • whether ThumbGate's bundled thumbgate MCP server config is present
Changes

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.
