SeeRepo with Codex

Codex, OpenAI's coding agent, works on your repo and opens pull requests. SeeRepo shows you what it changed and how it connects.

The signature it leaves

In the cloud, you connect GitHub when you create an environment, and you commit or open a pull request when you review a task (Codex cloud). OpenAI doesn't document the author name or the branch names of those commits.

How SeeRepo recognizes it

A commit counts as Codex's when its author or its Co-Authored-By line says "codex", "chatgpt" or has an openai.com address. A merge of a branch that starts with codex/ also counts.

On your computer, Codex signs its commits with "Co-authored-by: Codex [email protected]" only when commit attribution is on in your Codex account, and it comes off (Codex's code). Without that line, SeeRepo counts those commits as yours. To have it sign anyway, ask for it in your repo's AGENTS.md.

Where it shows in SeeRepo

• Made by, on a part's sheet: its logo next to the people. Click it and the map shows only what Codex touched.
• Journey: its posts tell, day by day, what it did, with its mark; Who wrote it, on the wall, what share it signed since the start. Tap it there to open its sheet: what it fixed, what it left and which modules it worked on this month, with the link to its posts. See Journey.
• Moments: the day it starts writing most of the project, the moment "Codex took over from …" stays.
• The filter: under Agent, pick Codex to see only its work.

The full list of agents SeeRepo recognizes is in the Agent directory.

Hand it a prompt from SeeRepo

SeeRepo writes prompts for what's worth fixing, ready for Codex:

1. Open Health and tap a task: failing tests, errors in production, packages with security flaws, files nothing uses… Its sheet opens. See Health.
2. Click "Copy prompt". The prompt names your repo, lists the files, and says what to do.
3. Paste it into Codex: it will know which files to read.

If your project has no automatic tests, Health says so in Tests ("They don't run on their own") and offers "Copy prompt to make them run on their own": Codex can set them up in a few minutes.
