Functions exposed to the LLM to take actions

Name	Description
list_skillsA	List available agent skills from the registry (skills.sh / GitHub). Returns compact metadata only (id, name, source, installs) - NO descriptions or content, so it is cheap on context. Use this to browse what is available before searching.
search_skillsA	Search for agent skills by keyword (name or description). Returns compact results: id, name, source, installs, and a short description preview (<=300 chars) when include_description is true. Use this to find a skill for a task. Query must be at least 2 characters.
load_skillA	Load the FULL content of one skill by id (e.g. "vercel-labs/skills/find-skills" or "anthropics/skills/document-skills"). Returns the complete SKILL.md plus optional supporting files. Use ONLY when you have decided to use a specific skill and need its full instructions - this is the expensive (context-heavy) call; prefer list_skills/search_skills first.
