codex-self-improvement-skills

Use when deciding whether a reusable lesson or repeated workflow should become a skill, memory, AGENTS rule, script, project doc, or stay unrecorded.

Use when improving an agent harness, prompt, workflow, tool order, retrieval strategy, subagent routing, or evaluation loop where multiple candidate approaches can be compared against observable results.

Use when a draft answer, code change, document, plan, or workflow decision needs a second-pass critique before final delivery, especially when correctness, completeness, safety, or verification quality matters.
