What problem does it solve? Valuable discoveries made during a long coding session — root causes, toolchain quirks, hard-won commands, and repeatable workflows — are easily lost when the session ends. This Skill scans the session transcript and turns those findings into durable CLAUDE.md notes, new reusable skills, and docs updates. ## Core Features & Use Cases - Learning extraction: Identifies non-obvious facts (root causes, environment quirks, exact commands) and drafts edits for the most specific CLAUDE.md or docs file. - Skill codification: Detects multi-step workflows repeated during the session and scaffolds new SKILL.md files with trigger-rich descriptions. - Docs gap and PR sweep: Flags user-facing changes missing from public docs and checks every PR touched for red CI and unread review feedback. - Use Case: At the end of a debugging-heavy session, ask for a retro to get a ranked proposal of what to record, then have the approved items written, committed, and opened as pull requests automatically. ## Quick Start Ask the assistant to run a session retro and scan this session for learnings and workflows worth keeping.
