What problem does it solve? Long-running, multi-session work loses context between agent runs, leaving stale plans, forgotten decisions, and no clear resume point. This Skill keeps a single project tracker file in the repo as the durable source of truth so work can be created, resumed, replanned, and closed out cleanly. ## Core Features & Use Cases - Durable project tracker: Creates and maintains a tasks.md tracker with milestones, a live Current Batch execution board, backlog, decisions, blockers, and a progress log. - Resume and replan workflow: Detects missing, active, stale, or finished trackers and resumes from Current Batch or rebuilds the plan in place before continuing. - Subagent delegation conventions: Provides rules for splitting read-heavy exploration, external research, and bounded implementation work while keeping the tracker single-writer. - Safe closeout and archival: Bundles scripts/archive_project.py to atomically move the complete project directory into the tracker home's archive folder with validated preconditions and JSON output. - Use Case: Ask an agent to carry a multi-week refactor across sessions; it records every batch, decision, and validation result in the tracker, then archives the whole project directory when the Done When criteria pass. ## Quick Start Use the project skill to create a tracker for my migration project, plan the first batch of work, and keep it updated until the project is done and archived.
