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 | $0.02837 | $0.02837 |
| Opus 5.5 | $0.01135 | $0.01135 |
| Sonnet 5.5 | $0.00567 | $0.00567 |
| Haiku 4.5 | $0.00284 | $0.00284 |
Grade A, and why
claude-code-codex-bridge AGENTS.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 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.
How it starts

Repository Overview
This repository is claude-code-codex-bridge.
It provides the cc-codex-bridge CLI, a standalone tool that bridges a local Claude Code setup into Codex-compatible artifacts without creating a second hand-maintained system.

Package Layout
- Runtime code lives under
src/cc_codex_bridge/. - Tests live under
tests/. - The installable CLI command is
cc-codex-bridge. - The Python module entrypoint is
python3 -m cc_codex_bridge.
Runtime Dependencies
The claude CLI must be available on PATH. The bridge shells out to claude plugins list --json to determine which plugins are enabled. Without it, discover() raises a DiscoveryError and the bridge cannot function.
Runtime Contract
The bridge reads local Claude Code state and produces Codex-compatible outputs such as:
CLAUDE.mdas the@AGENTS.mdshim~/.codex/agents/*.toml(global agent files, tracked in global registry).codex/agents/*.toml(project-local agent files)~/.codex/skills/*~/.cc-codex-bridge/projects/<hash>/state.json(per-project bridge state)~/.cc-codex-bridge/registry.json(global ownership registry)
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.
