Claude, Codex, and OpenCode Marketplaces

This repository contains three marketplace trees:

• claude-marketplace/ for Claude-facing plugins
• codex-marketplace/ for Codex-facing plugins
• opencode-marketplace/ for OpenCode-facing plugins

OpenCode support is rolling out in stages rather than matching Claude and Codex yet. Use the Platform Support Matrix and OpenCode Roadmap for current coverage and gating.

The repository root is a harness, not the canonical marketplace. Claude and Codex resolve through root shims:

• .claude-plugin/marketplace.json
• .agents/plugins/marketplace.json

OpenCode does not use a root marketplace manifest. Its install entrypoint lives at .opencode/INSTALL.md and installs either project-local .opencode/ files or global ~/.config/opencode/ files from the OpenCode marketplace subtree.

Shared support files live in shared/, but runtime plugin files stay inside the plugin roots that each platform resolves.

Where To Look

• Claude Marketplace
• Codex Marketplace
• OpenCode Marketplace
• Platform Support Matrix
• Migration Rules
• OpenCode Roadmap

Current Layout

• claude-marketplace/plugins/ contains the Claude plugin copies
• codex-marketplace/plugins/ contains the Codex plugin copies
• opencode-marketplace/plugins/ contains the OpenCode plugin copies
• .opencode/INSTALL.md contains the fetched OpenCode install instructions
• shared/ contains non-runtime support files such as validation scripts and references
• docs/ contains design notes and contributor guidance

Working Rule

Start with explicit platform-specific duplication. Only introduce generation or shared-source rendering if duplicated maintenance becomes a real problem.
