List all available skills with their names, descriptions and skill directories. Use this to discover which skill to invoke.
AI agents call superskills_list_skills to retrieve information from Superskills without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only discovery operation. It returns information about available skills (names, descriptions, directories) but does not execute code, modify data, or trigger any side effects. The blast radius of misuse is minimal—an AI agent could only learn what skills exist, which is informational and reversible.
From the tool's definition Tool name 'superskills_list_skills' and description 'List all available skills' indicate a query operation that retrieves metadata about available skills without modifying, executing, or deleting any data.
