Self-evolving skills for your coding agent — auto-create and auto-improve skills as you work, no trigger needed.
Skill Claude CodeCodex
Create a new reusable agent skill — either explicitly ("turn this workflow into a skill") or by reflecting on a just-completed task that you might do again. Synthesizes SKILL.md, scripts, and a real eval scaffold, then stages it for review before committing. Use when the user asks to make/save/capture a skill, or…

Find the right agent skill for a task from public sources (curated index, GitHub repos, and locally installed skills), then install the chosen one. Use when the user asks to find, search for, or discover a skill, or when a task would benefit from a skill you don't have yet.

Improve an existing skill through an evaluation-gated loop — run it on its eval tasks, analyze failures, propose bounded edits, validate a candidate, and (with your approval) promote a strictly-better version. Use when a skill underperforms or the user asks to optimize/tune/improve a skill that has an eval set.
Skill Claude CodeCodex
Share skills with your team and collaboratively improve them through a git-based workspace registry — publish a skill, sync the team's skills, pool eval results, and walk a reviewer through promoting a skill to a stable channel. Use when the user wants to share, publish, sync, or promote team skills.
