Each page on appsgit lists the environment variables a agent skill expects. ### Which coding agents work with these skills? Claude Code (all), Codex (9 of 10), Cursor (7 of 10) and OpenCode (5 of 10). The client list comes from each project's published compatibility data; appsgit does not guess it. ### Are any of these agent skills official? Yes: MCP Builder and X402 are published by the vendor themselves. ### How do I install an agent skill? A skill is a folder with a SKILL.md file that you copy into your agent's skills directory, or install from a plugin marketplace when the repository is one. Every skill page on appsgit shows the install command. ## Related questions - [What are the best agent skills for testing and QA?](https://appsgit.com/best/agent-skills-for-testing-qa) - [What are the best agent skills for docs and writing?](https://appsgit.com/best/agent-skills-for-docs-writing) - [What are the best agent skills for data analysis?](https://appsgit.com/best/agent-skills-for-data-analysis) - [What are the best agent skills for DevOps and cloud?](https://appsgit.com/best/agent-skills-for-devops-cloud) - [What are the best agent skills for design and frontend?](https://appsgit.com/best/agent-skills-for-design-frontend) - [What are the best agent skills for security?](https://appsgit.com/best/agent-skills-for-security) - [What are the best MCP servers?](https://appsgit.com/best/mcp-servers) - [What are the best MCP servers for Claude Code?](https://appsgit.com/best/mcp-servers-for-claude-code) ## See also - [Coding agent skills](https://appsgit.com/skills/category/coding) - [All agent skills](https://appsgit.com/skills) - [Trending agent skills](https://appsgit.com/skills/trending) - [Official agent skills](https://appsgit.com/skills/official) --- Canonical page: https://appsgit.com/best/agent-skills-for-coding Source: appsgit (https://appsgit.com), the app store for github.
