skill-creator
Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.
project-task-migrations
Manage project state using append-only, time-based Markdown files under /project/. Use when managing multi-epic projects, tracking decisions over time, maintaining audit trails, coordinating distributed teams, or requiring rollback visibility. Forces context loading, explicit confirmation gates, and immutable history preservation.
react-state-driven-ui
Create React UI as a projection of explicit state transitions using reducer + events. Use when building multi-step forms, async operations, cross-component state, navigation integration, real-time updates, or complex validation. Eliminates timing-dependent bugs through explicit state transitions and isolated side effects.
