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

claude-codex-team CLAUDE.md 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 2mo 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

Claude-Codex Team

Codex Bridge

This project develops the codex-bridge MCP server.

When planning features, designing architecture, or reviewing code, consult Codex via the codex-bridge MCP tools:

  • codex_plan before writing code — get a second opinion on approach
  • codex_review after writing code — get critical feedback on implementation
  • codex_ask for general brainstorming, questions, or trade-off discussions

Disagreement protocol: If Codex disagrees with your approach, surface it to the user with both perspectives. Don't silently pick a side.

Use codex_stats at the end of collaborative sessions to show the user how the collaboration went.

Benchmark

  • Hand-crafted samples: benchmark/samples/samples.json
  • HuggingFace samples: npm run bench:import-hf then npm run bench:hf
  • Run benchmarks: npm run bench (single) or npm run bench:avg (3-run average)
  • All benchmark commands run from the project root
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.
