Claude Code skills can now reflect on a session and self-update with confidence levels.

Recent skill tooling lets a skill review the session it just ran, extract the corrections you made, and rewrite itself, attaching confidence levels so low-confidence edits don't silently overwrite a proven workflow (Developers Digest). This closes the "stop copy-pasting the same workflow every session" loop by letting skills accrete improvements automatically. Review the high-impact self-edits before trusting them, but it removes most of the manual skill-maintenance grind. I want this wired into my daily pipeline yesterday.
