GitHub - wshobson/agents: Multi-harness agentic plugin marketplace for Claude Code, Codex, Cursor, OpenCode, GitHub Copilot, Google Antigravity, and Pi
Short summary
This is a repository that provides a single collection of 202 agents, 184 skills, and 105 commands designed to work across seven different coding environments—Claude Code, OpenAI Codex CLI, Cursor, OpenCode, Antigravity CLI, GitHub Copilot, and Pi. Each tool uses a "harness" that loads and runs these components according to its own capabilities, with adapters translating the source Markdown format into whatever format each tool needs.
- The system includes 94 plugins (92 local, 2 external) covering Python, JavaScript, code review, testing, infrastructure, and security work, with installation methods varying by target tool.
- Components are maintained once in Markdown source format, then automatically adapted to each harness's requirements—model aliases, tool permissions, and command formats differ by platform.
- Installation ranges from simple marketplace commands (Claude Code, Cursor) to cloning the repo and running make commands (OpenCode, Antigravity, GitHub Copilot, Pi), with individual skills installable via gh skill or npx.
Full summary
This repository offers a unified collection of 94 plugins containing 202 agents, 184 skills, and 105 commands that work across seven different coding environments: Claude Code, OpenAI Codex CLI, Cursor, OpenCode, Antigravity CLI, GitHub Copilot, and Pi. The core idea is maintaining a single Markdown source that gets adapted to each tool's specific format and capabilities rather than building separate plugin sets for each platform. You pick your preferred coding environment, follow its installation path, and gain access to components covering Python and JavaScript development, code review, testing, infrastructure, and security work.
The installation process varies by tool. Claude Code and Cursor use plugin marketplaces with straightforward registration. OpenAI Codex CLI offers native installation but splits large skill bodies into reference files due to an 8 KB budget constraint. For OpenCode, Antigravity CLI, GitHub Copilot, and Pi, you clone the repository locally and run a make command that generates the necessary artifacts and installs everything into your tool's configuration directory. Individual skills can also be installed standalone using GitHub CLI or npm without the full plugin ecosystem.
The repository validates its own quality through automated checks: `make generate-all` produces all format variants, `make validate` runs strict structural checks, and `plugin-eval` scores individual skills. The system maps abstract model choices like "opus" or "sonnet" to whatever each harness actually supports, and contributors follow shared authoring conventions so components work consistently across platforms. It's MIT licensed, though external plugins maintain their own licenses. Pensyve, a previously hosted service, shut down its cloud version in October 2026 but remains available as open-source software for self-hosting.
