Use when initializing Universal Token Killer schema artifacts for a project, discovering registered Copilot tools, seeding .utk output schemas, or narrowing schema generation to specific tool ids with descriptions or sample outputs
Use when compressing prompts, agent skills, AGENTS.md files, GitHub Copilot custom agents, subagent definitions, or bulky artifacts before sending text to LLM context; includes detoks-prompt CLI/MCP use, skill consolidation, AGENTS.md memory/skill extraction, and GHCP subagent/frontmatter orchestration
Use when configuring, testing, or documenting UTK model-proxy behavior for GitHub Copilot context optimization.
Use when optimizing Agent Skills for lower token usage, creating compact companion skills, splitting skill instructions into references, extracting deterministic workflow scripts, or adding eval-backed skill compression

Use this skill when installing, operating, or recovering Universal Token Killer (UTK) for GitHub Copilot tool-hook mediation.
UTK is hook-first. Do not expose mediation as a public CLI or VS Code extension. It observes shell and non-shell tool calls when the Copilot hook event includes enough input/output to mediate safely, persists raw artifacts under .utk/, infers schemas, routes by schema history, and returns compact references. The local detok MCP helper is only for LLMLingua-2 text rewriting.
