What problem does it solve? When an APM (Agentic Project Management) session ends, its Spec, Plan, Tracker, and Memory artifacts are scattered across the .apm/ directory with no consolidated record. This Skill produces a structured session summary and optionally archives all artifacts so the workspace is clean for the next session while history is preserved. ## Core Features & Use Cases - Session Summarization: Reads .apm/spec.md, plan.md, tracker.md, and memory notes, then writes a structured .apm/session-summary.md with YAML frontmatter (date, project, stages completed, outcome). - Subagent Cross-Validation: Spawns an explorer subagent to verify Task Logs against the actual codebase, confirming deliverables exist and commits are on expected branches. - Optional Archival: Runs apm archive --force to snapshot all .apm/ artifacts into .apm/archives/<name>/ and maintains an archive index table. - Use Case: After a Manager confirms all Stages complete, invoke this Skill to generate a point-in-time summary, review it with the user, and archive the session before running apm init for a fresh start. ## Quick Start Ask the assistant to summarize the current APM session and archive it with the default dated name.
