What is here

Claude Code reads .claude-plugin/marketplace.json, whose entries point at the plugin directory in each product repository. Codex reads .agents/plugins/marketplace.json; its local plugin source is packaged under plugins/ because Codex marketplace entries resolve inside the marketplace snapshot.

Plugin	Claude source	Codex source	What it gives your agent
kmp	underpass-ai/kmp	plugins/kmp	Local-first agent memory over thirteen MCP tools: ten memory moves plus three shared ChronoLoom view tools, with routing and setup diagnostics.
made	underpass-ai/made	Not cataloged yet	The MADE deliberation engine in process: design a ceremony from intent, publish it, and run it step by step.

Both plugins run their engine in process. Neither needs a service, a database or an API key to start.

Binaries

A plugin launcher runs the binary bundled in a release package when there is one, and otherwise falls back to the one on your PATH:

cargo install kmp-mcp     # for the kmp plugin
cargo install made-mcp    # for the made plugin

Release packages with a pinned binary are attached to each product repository's GitHub Releases.

Adding a plugin here

For Claude Code, add a git-subdir entry that points at the owning product repository. For Codex, place the validated plugin under plugins/<name> and append a local entry to .agents/plugins/marketplace.json with installation, authentication and category policy.
