Get started with Codex and fix a Rust WebSocket bug

Codex can write the fix fast. But does the change actually hold up once it hits a merge request? In this walkthrough, we reproduce a real Rust WebSocket metric filter bug, fix it with Codex in the terminal, and then follow the change into GitLab for pipelines, security scanning, and code review. You will see: - how to reproduce the bug with cargo, websocat, and curl - how Codex works from local repository context and AGENTS.md - how GitLab picks up the change after the push Hosted by Michael Friedrich, Principal Developer Advocate at GitLab Video series: - https://www.youtube.com/watch?v=IQxrwvzLai4 - https://www.youtube.com/watch?v=okx4cw2p-3I - https://www.youtube.com/watch?v=BapLAKxeomI Blog tutorial: https://about.gitlab.com/blog/fix-bugs-with-codex-and-gitlab Questions?
