Every time code is merged into your main GitHub branch, OpenAI Codex reads the diff, writes clear documentation for new functions and API endpoints, and commits it to your docs folder. Your documentation stays current without anyone spending time writing it by hand.

Step 1: Add a GitHub Actions workflow that triggers on every merge to main and sends the diff to the OpenAI Codex API.
Step 2: Prompt Codex to generate JSDoc, docstring, or markdown documentation depending on your language and preferred format.
Step 3: Commit the generated docs back to a '/docs' folder in the same repo via the GitHub API.
Step 4: Open a draft pull request with the new docs so a team member can review them before final merge.
