Why?

The coding agent ecosystem is fragmenting fast. Developers need a single source of truth — for agents, models, SDKs, benchmarks, tools, MCPs, skills, protocols, and research.

| 📊 | The Landscape | |----|--------------| | 10+ agents | AdaL CLI · Claude Code · Cursor · Copilot · Codex · Gemini CLI · Devin · Windsurf · Amp | | 5+ formats | AGENTS.md · CLAUDE.md · .cursorrules · copilot-instructions.md · SKILL.md | | 2 protocols | MCP (Model Context Protocol) · ACP (Agent Client Protocol) | | 8+ SDKs | AdalFlow · LangGraph · OpenAI Agents SDK · CrewAI · Pydantic AI · Smolagents · Strands Agents | | 60K+ repos | Already shipping AGENTS.md files across open source |

📖 Content

| Section | Description | |---------|-------------| | Coding Agents | Deep-dive profiles of every major AI coding agent | | Config Formats | How to write AGENTS.md, CLAUDE.md, .cursorrules, and more | | Protocols | MCP vs ACP — what they do and how they compare | | Benchmarks | LLM coding benchmarks — SWE-bench rankings, updated weekly | | Agent SDKs | AdalFlow, LangGraph, OpenAI Agents SDK, CrewAI, and the frameworks behind the agents | | Guides | Getting started, choosing an agent, multi-agent setups |

🤝 Contributing

We'd love your help! Here's how to get involved:

• Add a new agent — Create a file in src/content/docs/agents/ following existing patterns
• Improve existing pages — Fix errors, add examples, update benchmarks
• Add a config format — Document a new agent config format in src/content/docs/formats/
• Report issues — Open an issue for bugs, suggestions, or missing agents

See CONTRIBUTING.md for detailed guidelines.

Quick Start

git clone https://github.com/SylphAI-Inc/codingagents.md.git
cd codingagents.md
npm install
npm run dev    # → http://localhost:4321

Content lives in src/content/docs/ — add or edit Markdown files and they appear in the sidebar automatically. No build config needed.
