WhatIsIt
A reference implementation of the System Skill Pattern for building Claude Skills that remember, learn, and improve over time. It demonstrates the pattern through a fully functional Pomodoro timer, combining a CLI tool, SKILL.md guidelines, and a database for persistent state. A practical example of how to build stateful, self-improving Claude Skills.
HowToUse
The skill implements a Pomodoro timer with Claude integration:
- Start a session - Begin a 25-minute focused work period with a clear task description
- Track progress - The system monitors your sessions and breaks
- Review history - Query past sessions, completion rates, and productivity patterns
- Learn and adapt - The system learns from your patterns and suggests optimizations
More importantly, it serves as a template for building your own stateful skills using the System Skill Pattern (CLI + SKILL.md + Database).
