Each plugin ships parallel manifests. Plugins marked as Codex-compatible include Codex-loadable components such as skills:
plugin-name/
├── .claude-plugin/
│ └── plugin.json # Claude Code manifest
├── .codex-plugin/
│ └── plugin.json # Codex CLI manifest (mirrors the Claude manifest)
├── commands/ # Slash commands (Claude Code primary)
├── skills/ # Agent skills (shared — same SKILL.md format)
├── agents/ # Subagents (shared)
├── hooks/ # Event handlers (Claude Code format)
├── .mcp.json # MCP servers (Claude Code)
└── README.md
The marketplace catalog is mirrored at two locations:
.claude-plugin/marketplace.json— Claude Code.agents/plugins/marketplace.json— Codex CLI
Run scripts/sync-marketplace.sh after editing the Claude file to update the Codex mirror, and scripts/validate-plugins.sh to verify manifests and Codex marketplace schema. See AGENTS.md for the full compatibility matrix.
