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

Codex Review 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 8d 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

Review the code specified below using Codex as a sub-agent.

Steps

  1. Read the target file(s) specified in the arguments. If no file is specified, ask the user.
  2. Call mcp__codex-bridge__consult_codex_with_stdin with:
    • stdin_content: the full content of the target file(s)
    • prompt: "Review this code. Focus on: bugs, security issues, performance problems, and readability. Return a structured list of findings with severity (critical/warning/info), location, and suggested fix."
    • format: "json"
    • timeout: 180
    • sandbox: "read-only"
  3. Summarize findings, highlighting the most critical issues first.

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.
