List the GitHub skill repositories configured for this MCP server.
AI agents call github_skills_list_repositories to retrieve information from Agent Skills MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of configured repositories—a read-only operation that does not modify, execute, or delete data. The blast radius of misuse is minimal since it only exposes information about available repositories.
From the tool's definition Tool name 'list_repositories' and description 'List the GitHub skill repositories configured for this MCP server' indicate a retrieval operation with no side effects.
