Get all skills, optionally filtered by category
AI agents call get_skills to retrieve information from Enhanced MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple data retrieval operation ('Get all skills') with optional filtering, which is a classic Read category operation. There are no side effects, no data modification, and no external command execution. The filtering capability does not change the fundamental read-only nature of the operation. Severity is low because retrieving skills data has minimal blast radius even if misused by an AI agent.
From the tool's definition Tool name 'get_skills' with description 'Get all skills, optionally filtered by category' indicates a retrieval operation with optional filtering parameters. No modification, deletion, or execution of external operations is implied.
