What problem does it solve? After a development cycle ends, valuable lessons—what worked, what broke, and why decisions were made—are usually lost. This Skill captures those insights from completed keel development cycles and turns them into reusable pattern documents so future iterations avoid repeated mistakes. ## Core Features & Use Cases - Pattern Extraction: Reviews verify reports, dev task documents, and git history to identify positive patterns, pitfalls, key decisions, and workflow improvements. - Deduplication & Confirmation: Scans existing patterns in docs/devdocs/patterns/ to avoid duplicates and confirms each candidate with the user before writing. - Verify Blindspot Loop: Records issues that verification missed into verify-blindspots.md, feeding back into future verification runs. - System Learning Check: Every run answers whether lessons should become rules, templates, or automated checkers. - Use Case: After finishing a feature with /sync and /verify, run /compound to distill two reusable patterns and one template gap into docs/devdocs/patterns/ for the next iteration. ## Quick Start Ask the AI to run the compound skill to extract reusable patterns and lessons from the just-completed development cycle.
