What problem does it solve?
This Skill eliminates the risk of losing track of project milestones, task deadlines, and multi-agent task lineage when working on distributed AI agent workflows, removing the need to manually reconstruct task history after context switches, worktree changes, or agent session ends.
Core Features & Use Cases
- Unified Schedule Management: Tracks project milestones, tasks, start/due dates, overdue items, and auto-generates Mermaid Gantt charts for full timeline visibility.
- Multi-Agent Lineage Tracking: Automatically records spawn/return/merge relationships for fan-out agent tasks, preserving recovery points even after session distillation or worktree cleanup.
- Use Case: When running a multi-agent research project with 3 parallel sub-tasks, use this Skill to track each sub-task's parent, completion status, and return point to avoid orphaned work after agent sessions end.
