AGENTS.md gives that guidance its own dedicated file, written in plain Markdown with no required schema, so agents find it reliably while READMEs stay short and human-friendly. Because it is just Markdown, there is nothing to install and no proprietary tooling to adopt. You add an AGENTS.md at the repository root, list the sections that matter for your project, and agents that support the convention read it automatically. In large monorepos you can place additional AGENTS.md files inside subpackages; agents read the nearest file in the directory tree, so the closest one wins and each package can ship tailored instructions. The format emerged from collaboration across the AI developer ecosystem — including OpenAI Codex, Amp, Google's Jules, Cursor and Factory — and is now stewarded by the Agentic AI Foundation under the Linux Foundation. It is used by over 60,000 open-source projects and supported by a long list of agents including Codex, Jules, Aider, goose, opencode, Zed, Warp, VS Code, Devin, Amp, Cursor, RooCode, Gemini CLI, Kilo Code and GitHub Copilot. **Pricing & Plans:** AGENTS.md is completely free and open. There is no paid tier, no account and no commercial product attached to the format. - **Plain Markdown, no schema:** There are no required fields or special syntax. Use any headings you like and the agent parses the text you provide. - **Cross-agent compatibility:** One AGENTS.md works across dozens of coding agents such as Codex, Cursor, Jules, Aider, Gemini CLI, Zed and Copilot. - **Nested files for monorepos:** Drop extra AGENTS.md files into subpackages; agents read the nearest file in the directory tree, so local instructions take precedence. - **Separation from README:** Keeps human-facing READMEs concise while giving agents the build, test and convention details they actually need. - **Community-governed open format:** Stewarded by the Agentic AI Foundation under the Linux Foundation, with no vendor lock-in. **Strengths:** Zero setup: it is just a Markdown file, no SDK or account needed; Works consistently across a large and growing set of coding agents; Nested support makes it practical for large monorepos; Governed by a neutral foundation, so no single vendor controls it **Limitations:** Agents vary in how fully they honor the instructions they read; Without discipline it can drift out of date like any documentation; No formal schema means structure differs substantially between projects [Profile (Markdown)](https://openaitools.app/tool/agents-md.md) ## CopilotHub CopilotHub is a discovery and reference site for developers who already use GitHub Copilot and want to get more out of it. Instead of hunting through blog posts for prompt ideas, you get a structured catalog: curated prompts organized by language or framework (React, TypeScript, JavaScript, Tailwind, SQL, Next.js and more), reusable instruction sets that apply best practices automatically, specialized agents, and a directory of MCP servers and extensions that extend what Copilot can reach. The site's flagship feature is its Migration Hubs. These are production-oriented playbooks that bundle guides, prompt sequences, and workflows for upgrading real codebases — for example moving a Spring Boot 2 application to Spring Boot 3 with Jakarta EE and Hibernate 6, or migrating Next.js Pages Router projects to the App Router. Each hub is split into discrete prompts you can copy and run, so a large refactor becomes a checklist of small, reviewable AI-assisted steps. Every entry is tagged and copy-ready, and the catalog is browsable by technology, category, or use case. Sign-in is handled through GitHub, and much of the underlying content is contributed by the community and open for contributions. The platform is free to browse and use; there is no paid tier advertised. **Pricing & Plans:** Free to use. The directory is browsable without payment and prompts can be copied freely; no paid plans are advertised. GitHub sign-in unlocks contribution and personalization features. - **Curated prompt library:** Hundreds of tagged, copy-ready prompts for code review, refactoring, documentation, debugging, testing and framework-specific tasks across React, TypeScript, JavaScript, Tailwind, SQL and Next.js. - **Migration Hubs:** Production-grade playbooks for upgrading real codebases, including prompt-by-prompt guides for Spring Boot 2→3, Jakarta EE, Hibernate 6, and other framework or language migrations. - **AI agents & instructions:** Reusable agent configurations and coding instruction files that shape Copilot's behavior so it follows consistent, high-quality conventions on your projects. - **MCP server & tool directory:** A browsable index of MCP servers, extensions and developer tools that expand what GitHub Copilot can access and automate. - **Community contributions via GitHub:** Sign in with GitHub to submit prompts and resources, so the catalog grows with contributions from working developers. **Strengths:** Free and open to browse, with copy-ready prompts and no paywall; Strong focus on real-world migration and modernization workflows rather than generic prompt tricks; Well organized with tags and categories by language and framework; Community-driven with GitHub-based contribution flow **Limitations:** Content coverage varies by technology, with some frameworks having far more prompts than others; Some Migration Hubs are marked "coming soon", so coverage is still expanding; No in-editor integration or prompt execution — it is a reference library you copy from [Profile (Markdown)](https://openaitools.app/tool/copilothub.md) ## Frequently Asked Questions ### How do AGENTS.md and CopilotHub compare in monthly traffic?
