Copy and paste this into your codex:
“Look through my recent Codex sessions and identify repeated workflows or repeated asks.
For anything I keep doing manually, suggest:
1. a skill if it is a reusable workflow
2. a custom subagent if it is a bounded role or investigation task
Focus on practical things like CI failures, PR reviews, changelogs, docs updates, release prep, debugging, and test triage.
Create the useful ones only. Keep them simple.”
