How do I install a Claude Code plugin?

Add the marketplace that lists it, then install it by name: claude plugin marketplace add owner/repo followed by claude plugin install plugin-name@marketplace-name. Inside a session the same thing is /plugin marketplace add owner/repo and /plugin install plugin-name@marketplace-name. Every plugin page here shows the exact two lines.

How do I install a Codex plugin?

Codex uses the same two steps: codex plugin marketplace add owner/repo, then codex plugin add plugin-name@marketplace-name. Codex reads its own .agents/plugins/marketplace.json and also Claude's .claude-plugin/marketplace.json.

Where does this list come from?

From GitHub. Every day we look for repositories with a .claude-plugin/marketplace.json, .claude-plugin/plugin.json, .codex-plugin/plugin.json or .agents/plugins/marketplace.json, read the manifests the same way the CLIs do, and list what each plugin contains. Nothing here is hand-written.

How do I get my plugin listed?

If it's a public GitHub repo with a plugin manifest, it will be found automatically. To list it right now, paste the repo URL on the Add a plugin page — it's checked and live in seconds, and you'll see any manifest problems that would break installs.

Is a plugin safe to install?

Plugins can run code: hooks fire on events and MCP servers start local processes. Each plugin page lists those exact commands, so you can read them before installing.

ifixai

claudecodex

Independent auditing for AI agents, open source. Claude discovers your setup, confirms the cost, and audits your agent against the one question other tools skip: is it doing the job it's supposed to do, given your business rules and org structure? Test any model (Anthropic, OpenAI, Gemini, Azure, Bedrock, …) graded by self, one independent judge, or a cross-vendor panel; each provider is billed to its own account via a key in your settings, never the command line. Results render as an interactive artifact (with a static-report fallback).
