List available skills, optionally filtered by folder / search / source / folderTag.
AI agents call skills__list to retrieve information from SkillForge MCP 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 operation that queries and returns information about available skills with optional filtering parameters. It has no side effects, does not execute code, modify data, or trigger external operations. The blast radius of misuse is minimal—an attacker could discover available skills but cannot invoke them, modify them, or cause damage through listing alone.
From the tool's definition Tool name 'skills__list' and description 'List available skills, optionally filtered by folder / search / source / folderTag' indicates retrieval and enumeration of existing skills without modification or execution.
