Best Codex Workflows for PR Review
Codex-ready pull request review workflows should make repository context explicit, explain the review rubric, and keep model credentials local. A useful workflow does more than summarize a diff: it points reviewers toward risky files, missing tests, permission changes, dependency updates, and follow-up commands that can be checked safely.
What to look for
Start with AGENTS.md or an equivalent instruction bundle. It should define project conventions, test commands, review boundaries, approval expectations, and prohibited actions. Strong workflows separate evidence collection from recommendations so reviewers can see why a change is considered risky.
Risk signals
Strong PR review workflows pay attention to authentication changes, database migrations, shell execution, external writes, billing paths, GitHub Actions permissions, and generated code. These areas should trigger human approval instead of automatic merge behavior.
