skill-improve
Apply evidence-based improvements to an existing skill using signals from the current session.
What it does
Takes an existing skill directory and one or more improvement signals — grill output, audit findings, eval failures, human feedback, or inline session context — and applies targeted edits to the skill files. Groups signals by root cause before editing to avoid per-symptom patching. Hands off to /skill-audit when done.
Before you start
Have at least one improvement signal ready: a grill session output, /skill-audit report, eval results, feedback.json, or inline feedback describing what went wrong. If you have no signals and want a blind review, use /skill-audit instead.
Usage
/skill-improve
Provide the skill directory path and any signal files in the conversation. The skill gathers signals from context — you don't need to paste them in a specific format.
