What problem does it solve? Claude Code sessions are ephemeral, so context, decisions, and in-progress work are lost between sessions. This Skill preserves project state across sessions by discovering prior work, loading handoff documents, and generating structured handoffs at session close. ## Core Features & Use Cases - Session Resume: Detects prior session state from .workflow/ files, git history, and plan files, then presents a session brief with completed, in-progress, and blocked items. - Structured Handoffs: Generates markdown handoff documents and JSON session state files capturing decisions, files modified, and prioritized next actions. - Parallel Session Sync: Synchronizes multiple concurrent agent sessions, flagging file conflicts without auto-resolving them. - Use Case: You run a swing-shift workflow where an evening session must pick up exactly where the morning session stopped. Session-manager reads the prior handoff, verifies git state, and resumes from the exact next action. ## Quick Start Ask Claude to resume your previous session and summarize what was completed, what is in progress, and the recommended next actions.
