Fix bugs with Codex and GitLab

What this post added

This post details the integration of Codex, an AI coding agent, with the GitLab Duo Agent Platform to automate bug fixing and enhance the software development lifecycle. It outlines three use cases: fixing a Rust WebSocket bug locally, enriching context with GitLab MCP for issue-aligned fixes, and using Codex as an external agent to address review feedback. The post highlights how GitLab's CI/CD, Duo Code Review, and MCP server provide the necessary context and automation to move from AI-generated code to shipped software.
