SkillTree

Generates, aggregates, and extends modular skill-trees with hierarchical routing. Supports three modes — (1) convert a monolithic skill into a tree with ROOT.md/ROUTER.md/SKILL.md, (2) aggregate multiple skills into a unified cross-domain tree with shared leaves and disambiguation, (3) incrementally update an existing tree by adding new skills. Use when users need to restructure, merge, or extend skills into context-aware, load-on-demand hierarchies.
