Overview

Tool for loading skills from memory and dynamically swapping agent tools

LoadSkill reads a skill from memory, validates it, and swaps the agent's mutable tools to match the skill's requirements. Immutable tools (Memory*, Think, LoadSkill) are always preserved.

Skills must:

  • Be stored in the skill/ hierarchy
  • Have type: 'skill' in metadata
  • Include tools array in metadata (optional)
  • Include permissions hash in metadata (optional)
