MCP-to-Skill Converter

Convert MCP servers into on-demand skills. MCP tool schemas sit in the system prompt on every turn (~500-2000 tokens per tool, regardless of whether they're used). Skills cost zero tokens until loaded via view. For a typical setup with 4-5 MCP servers exposing 20-40 tools, this reclaims 10,000-30,000 tokens of context per turn.

This matters because that's 10-30% of the context window burned before the conversation even starts — and it compounds: every turn re-injects the full schema.

Decision Framework: Convert vs. Keep

Not every MCP should become a skill. Apply this heuristic:

Convert when the MCP wraps a REST API (use curl/web_fetch), wraps a CLI tool (gh, aws, gcloud — invoke directly), implements a reasoning/planning pattern (capture as methodology), or when you use fewer than half its tools regularly.
