How PMs Use the Codex App

Original Description

Alexander Embiricos (a Product Manager on the Codex team) shows how he uses Codex skills to make a small product change, diagnose a Buildkite failure, and improve the skills so the next PR goes faster.

Takeaways:

- Skills are a shortcut for repeated workflows like Buildkite logs.

- When a skill fails, fix the root cause and update the skill.

- The real win is compounding: the codebase gets easier over time.

This is the loop: ship the fix, then teach the workflow.
