+## Skill Workshop
+
+The optional, experimental Skill Workshop plugin can create or update workspace
+skills from reusable procedures observed during agent work. It is disabled by
+default and must be explicitly enabled through
+`plugins.entries.skill-workshop`.
+
+Skill Workshop writes only to `<workspace>/skills`, scans generated content,
+supports pending approval or automatic safe writes, quarantines unsafe
+proposals, and refreshes the skill snapshot after successful writes so new
+skills can become available without a Gateway restart.
+
+Use it when you want corrections such as “next time, verify GIF attribution” or
+hard-won workflows such as media QA checklists to become durable procedural
+instructions. Start with pending approval; use automatic writes only in trusted
+workspaces after reviewing its proposals. Full guide:
+[Skill Workshop Plugin](/plugins/skill-workshop).
