One section in, one section out — on Markdown/GEML files, bad writes refused.
GEML — a plain-text document format built to be edited in place, one section at a time is an MCP server entry in ChatHome Skills, sourced from Official MCP Registry and scored 76/100. As a Model Context Protocol server, it exposes tools that MCP-compatible LLM clients such as Claude, Cursor, and Copilot can call directly, extending an agent's reach beyond its built-in capabilities. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page. The install command above is ready to copy. Review the last-pushed date and repository status before adding GEML — a plain-text document format built to be edited in place, one section at a time to a production agent workflow; the snapshot facts below are point-in-time values from the most recent ingest.
