Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A plugin that lets the Opencode coding tool sign in to Google's Antigravity IDE via OAuth to use its models.
Open source · MIT
A collection of plugins, agents, skills, and commands that run across several AI coding tools.
The short answer
Choose Antigravity if you need…
- Developers who already use Opencode and have a Google account with Antigravity access
- People who want to switch between several Google accounts and check their quota status
- Users comfortable editing a JSON config file and running commands in a terminal
Choose wshobson/agents if you need…
- Developers who already use one of the listed AI coding tools and want ready-made specialist agents
- Python or JavaScript/TypeScript developers looking for testing, packaging, or project setup guidance
- Teams wanting a shared set of review and security-scanning workflows across different tools
- People who want to install only individual skills without the full plugin set

What each one is
Antigravity
This is an unofficial plugin for Opencode, a terminal coding tool. It lets you sign in with your Google account through OAuth so Opencode can call models that Antigravity (Google's IDE) provides, such as Gemini and Claude models, using Antigravity's rate limits. Accounts are stored locally, and the README notes that Google may restrict accounts that use third-party clients.
wshobson/agents
This project is a shared library of prompts-as-plugins for AI coding assistants. It contains 94 plugins with specialist agents, skills (reference guidance an agent loads when relevant), and commands (named workflows) covering areas like Python, JavaScript, code review, testing, infrastructure, and security. One Markdown source is adapted to Claude Code, OpenAI Codex CLI, Cursor, OpenCode, Antigravity CLI, GitHub Copilot, and Pi.
Best for
Antigravity
- Developers who already use Opencode and have a Google account with Antigravity access
- People who want to switch between several Google accounts and check their quota status
- Users comfortable editing a JSON config file and running commands in a terminal
wshobson/agents
- Developers who already use one of the listed AI coding tools and want ready-made specialist agents
- Python or JavaScript/TypeScript developers looking for testing, packaging, or project setup guidance
- Teams wanting a shared set of review and security-scanning workflows across different tools
- People who want to install only individual skills without the full plugin set
Strengths
Antigravity
- Uses the setup flow already built into opencode auth login
- Lets you manage several accounts and see quota status in one place
- Written in TypeScript under the MIT license with a documented test suite
wshobson/agents
- Covers seven coding tools from one shared source of components
- Large catalog: 94 plugins, 202 agents, 185 skills, and 105 commands according to the README
- Offers a skills-only install route that does not require the full plugin set
Not ideal for
Antigravity
- Anyone who needs guaranteed account safety, since the README warns Google may restrict accounts using third-party clients
- People not using Opencode, because the plugin only works inside it
- Users on older Opencode or Node.js versions, since it requires OpenCode 2.1.2+ and Node.js 20+
wshobson/agents
- People who do not use any supported AI coding tool, since the components only run inside those harnesses
- Anyone expecting the scores from the plugin-eval tool to prove a task will succeed, because the README says the LLM judge and Monte Carlo layers are experimental and not validated against human labels
- Users wanting a fully stable, versioned release, since the README lists no latest release
Trade-offs
Antigravity
- Unofficial, and Google may restrict accounts using third-party clients
- Model availability depends on your Google plan and the README does not spell out limits
- Accounts file contains credentials and must be backed up and protected carefully
wshobson/agents
- The README notes that available components depend on the installation route and each harness's limits, so features differ by tool
- Some features (LLM judge, Monte Carlo evaluation) are experimental and may bill your Anthropic API account if ANTHROPIC_API_KEY is set
- Pi agents need a separate subagent extension, and the Codex native and generated routes behave differently
