The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Codex Fast Proxy

Local auth-split proxy that gives OpenAI Codex App priority (Fast) tier on third

Test report

Verdict: Works with setup
Score: 7.6/10
Tested: Jul 19, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · bb20044

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 19, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

This is a Codex App skill, not a Claude Code one: every action calls 'python -m codex_fast_proxy', which fails with 'No module named codex_fast_proxy' until you run the repo's separate editable pip install and have a running Codex App plus a third-party provider API key. Output was unmeasured because none of that could be stood up here; the code itself reads auth keys locally and forwards only to 127.0.0.1 and the user-configured upstream, with no exfil.

What Codex Fast Proxy does

Drives a local proxy that splits auth and injects priority service_tier so OpenAI's Codex App can use Fast against third-party OpenAI-compatible providers, with enable/status/benchmark/uninstall flows and ChatGPT-login compatibility. Built for the Codex ecosystem, not Claude Code: its python -m codex_fast_proxy commands need a separate package install and a running Codex App. Triggers on 'enable Codex Fast proxy', 'make Codex App use Fast', '401 on model requests'.

How to install Codex Fast Proxy

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Commands — how to trigger Codex Fast Proxy

/codex-fast-proxy Local auth-split proxy that gives OpenAI Codex App priority (Fast) tier on third

It also activates on plain-language prompts like these:

Enable the Codex Fast proxy so my Codex App gets priority tier.
My Codex App keeps getting 401s on model requests, fix it.
Benchmark whether Fast tier is actually faster for my provider.
