What problem does it solve? Code changes persist in git, but the reasoning behind decisions disappears when a session ends. This Skill preserves the context and rationale of decisions so future you (or teammates) can understand why past choices were made. ## Core Features & Use Cases - Decision-focused summarization: Records why decisions were made, not just what was done, with a summary-first structure prioritizing request, context, and outcome. - Structured storage: Saves history files to ~/history/{YYYY}/{MM}/{DD}/{project}/ with kebab-case slugs and maintains a ~/history/index.jsonl index for deduplication and continuity. - Trigger discipline: Only activates on explicit end-of-session signals combined with recordable content (code changes, design decisions, or user feedback), avoiding noise from read-only sessions. - Use Case: After a long debugging and refactoring session, say "세션 정리해줘" and get a concise markdown record capturing the original request, key decisions with rationale, feedback applied, and follow-up tasks. ## Quick Start Ask the AI to summarize and save this session's work as a history file when you are wrapping up.
