Taskmaster.
Task decomposition. Sprint planning. Burndown. Multi-session persistence. GitHub Issues + Projects integration.
Sprint Planning, Progress Tracking, GitHub Issues.
Big features die when they are not decomposed. This skill: break a feature into tasks with explicit dependencies, track progress with burndown, persist state across multiple work sessions, and integrate with GitHub Issues so the work surface and tracking surface are the same.
Four recipes.
Decomposition rules
Each task at most 1 day of work. Each has acceptance criteria. Dependencies explicit (X must finish before Y starts). No more than 3 levels of nesting (epic, story, task).
Sprint planning
Capacity = velocity times team size times focus factor (~0.7). Do not commit beyond capacity. Stretch goals separate. Reserve 20% for unplanned work.
Burndown + velocity
Daily ideal vs actual remaining. Find velocity from past 4 sprints (4-sprint moving average). Use it to predict end date.
GitHub Issues integration
Issues = tasks. Labels = epic + priority + complexity. Projects = sprint board. Milestones = release. PR auto-closes issue. Live source of truth.
It composes.
Skills compose into workflows. Taskmaster is rarely the only skill you will use — it pairs naturally with these others in the library.
