agents.md guides agents. codingagents.md helps humans pick the right one.
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.

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.
