Restore a working Codex-specific llms.txt endpoint

Resolved 💬 1 comment Opened Jul 29, 2026 by jtsang4 Closed Jul 29, 2026

What is the issue?

The Codex docs previously exposed https://developers.openai.com/codex/llms.txt, which agents could use as an LLM-friendly index for Codex and plugin development guidance. It now redirects to https://learn.chatgpt.com/docs/llms.txt and returns 404. The root https://developers.openai.com/llms.txt still lists the broken Codex index and full-doc URLs.

Please provide a stable, working Codex-specific llms.txt endpoint (and ideally llms-full.txt), or update the root index with the new canonical URLs. This would let agents reliably discover the current Codex and plugin development documentation.

Where did you find it?

Apologies—I missed that the working canonical index is available at https://developers.openai.com/llms.txt. It provides the documentation index I needed, so this request is unnecessary. Sorry for the noise, and thank you.
