Agent Plugins

Cross-agent plugins and skills for solo-founder speed: small, practical bundles that help AI agents build, ship, debug, and operate real products.

This repository is both:

• a Claude Code plugin marketplace, via .claude-plugin/marketplace.json
• a Codex plugin marketplace, via .agents/plugins/marketplace.json

It also keeps the underlying workflows as normal SKILL.md files so Gemini, Hermes, OpenCode, and other agentskills-compatible runtimes can reuse the same source material.

Marketplace Name

agent-plugins-marketplace

The name is intentionally broad because this repo will host more than build-visionos-apps over time.

Available Plugins

build-visionos-apps

Build, refine, and debug visionOS apps with SwiftUI scenes, RealityKit, Reality Composer Pro, immersive spaces, spatial gestures, and Xcode workflows.

Included skills:

• build-run-debug-visionos
• visionos-scenes-and-spaces
• realitykit-entities
• reality-composer-pro
• spatial-gestures-interaction

Install

Claude Code

Register this marketplace:

/plugin marketplace add likw99/agent-plugins

Install the first plugin:

/plugin install build-visionos-apps@agent-plugins-marketplace

Codex CLI / Codex App

Register this marketplace:

codex plugin marketplace add likw99/agent-plugins

Install the first plugin:

codex plugin add build-visionos-apps@agent-plugins-marketplace

Start a new thread after install so newly exposed skills and tools are loaded.

Gemini CLI

Gemini CLI uses extensions rather than the Claude/Codex marketplace manifest. Install this repo as a lightweight catalog extension:

gemini extensions install https://github.com/likw99/agent-plugins

Then ask Gemini to use the relevant plugin docs under plugins/.

Hermes

Hermes should consume the SKILL.md files directly. See docs/hermes.md for the skill-first install path.

OpenCode

OpenCode users can start from .opencode/INSTALL.md, which points agents at the same durable plugin instructions.

Official Marketplace Notes

See docs/official-marketplaces.md.

Short version:

• Claude has a documented public submission path through in-app forms.
• Codex has a documented plugin library, but no public self-serve official submission form was found in current public docs.
