## What firmament does, in the publisher's words

One repo, four ecosystems: this marketplace serves Claude Code (and Cowork) via.claude-plugin/, OpenAI Codex via.codex-plugin/ +.agents/plugins/, GitHub Copilot CLI (reads the Claude format directly), and Cursor via.cursor-plugin/ + firmament-cursor/.

Since v0.2.8 plugins/firmament/ is also a conformant Agent Plugins 1.0.0 package: a root plugin.json, mcp.json and skills/ sitting alongside the per-vendor manifests. The two layouts share one directory without colliding (.mcp.json and mcp.json are different files), so every client above keeps reading exactly what it read before. One caveat: the portable mcp.json schema is closed and has no timeout field, so an Agent Plugins client gets its own default rather than the 5.5-minute wait.mcp.json sets for Claude Code.

- Codex: codex plugin marketplace add spkenny455/firmament-plugin then codex plugin add firmament@firmament
