Audit the always-on context cost of an agent setup: installed skills, memory files (CLAUDE.md, AGENTS.md), and MCP tool schemas. Use when asked to audit, trim, shrink, or cut skills or context, after installing a skill pack or connecting an MCP server, when an agent picks the wrong skill or feels dumber after the setup grew, when MCP servers eat the context window, or when the token bill grows without more work getting done. Produces a keep/trim/cut table with measured numbers. Does not delete anything.
