What problem does it solve? Skills accumulate friction over repeated runs: improvised decisions, manual work that should be scripted, and instructions that get ignored. This Skill harvests that friction from a recent run and turns it into concrete, verified edits to the skill files. ## Core Features & Use Cases - Friction Harvesting: Systematically identifies improvisation, manual labor, user corrections, and dead instructions from a skill run. - Fix Classification: Maps each friction item to the right fix type, preferring shipped scripts and construction-time guarantees over checklist additions. - Closed-Loop Verification: Re-runs the edited skill to prove each change works, and records the outcome in a dated changelog. - Use Case: After a skill run where the agent hand-wrote a helper and guessed at a naming rule, invoke this Skill to ship the helper in the skill's library, codify the naming rule, and re-run to confirm both fixes hold. ## Quick Start Ask the agent to run a retrospective on the skill you just used and improve it based on what went wrong in that run.
