Captures learnings, errors, and corrections to enable continuous improvement. Use when: (1) A command or operation fails unexpectedly, (2) User corrects Claude ('No, that's wrong...', 'Actually...'), (3) User requests a capability that doesn't exist, (4) An external API or tool fails, (5) Claude realizes its knowledge is outdated or incorrect, (6) A better approach is discovered for a recurring task. Also review learnings before major tasks.
Initial release of the self-improvement skill for structured learnings and error logging. - Enables agents to capture learnings, corrections, errors, and feature requests in dedicated markdown files under `.learnings/`. - Provides clear logging templates and category/tag structure for learnings, errors, and feature requests. - Outlines criteria for promoting broadly relevant learnings to persistent project memory files (`CLAUDE.md`, `AGENTS.md`). - Includes guidelines for recurring pattern detection, priority assignments, and periodic review practices. - Offers quick reference tables, command examples, and review scripts to streamline adoption. - Designed to support continuous improvement and reduce repeat mistakes.
