## What cm-gpt does, in the publisher's words

Brings CM GPT, the Critical Manufacturing MES documentation assistant, into both Claude Code / Cowork and ChatGPT / Codex, from the same plugin folder. Bundles the connector to the CM GPT MCP server together with the search-and-answer instructions that were previously carried as a LibreChat agent system prompt.

This works on both platforms because Claude Code and OpenAI's Codex/ChatGPT plugin system now share the open Agent Plugins manifest format. Concretely:

- skills/ask/ is read as-is by both platforms: one skill file, no duplication.
- plugin.json (root) + mcp.json (root) are the portable Agent Plugins manifests, used by Codex/ChatGPT.
- claude-plugin/plugin.json +.mcp.json are Claude Code's own manifest format. OpenAI's docs say it also accepts these as a legacy/compatibility fallback, but this repo keeps both pairs explicit rather than relying on that fallback.
