# Chat Compactor Generate structured summaries optimized for AI agent continuity across sessions. ## Why This Exists Human-written summaries and ad-hoc AI summaries lose critical context: - **Decision rationale** gets lost (why X, not Y) - **Dead ends** get forgotten (agent re-tries failed approaches) - **Implicit knowledge** isn't captured (file locations, naming conventions, gotchas) - **State** is unclear (what's done, what's pending, what's blocked) This skill produces **agent-optimized handoff documents** that prime the next session. ## Output Format Generate a markdown file with this structure: ```markdown # Session: [Brief Title] Date: [YYYY-MM-DD] Duration: ~[X] messages ## Context Snapshot [1-2 sentences: What project/task, what state it's in right now] ## What Was Accomplished - [Concrete outcome 1] - [Concrete outcome 2] ## Key Decisions & Rationale | Decision | Why | Alternatives Rejected | |----------|-----|----------------------| | [Choice] | [Reason] | [What didn't work and why] | ## Current State - **Working**: [files/features that are functional] - **Broken/Blocked**: [what's not working and why] - **Modified files**: [list with brief note on changes] ## Dead Ends (Don't Retry) - ❌ [Approach that failed] — [why it failed] ## Next Steps (Prioritized) 1.
