Agents.md Decision Guide – open-source tool for choosing agentic workflows A new open-source tool called Agents.md Decision Guide helps developers build AGENTS.md files to define stack, rules, and patterns for AI coding agents, replacing manual creation with a guided selection process. groundwork Your AI coding agent is only as good as the context you give it. AGENTS.md is how you do that — it's the file that tells your agent your stack, your rules, your patterns, and how your team works. Stop writing it by hand. Pick a category on the left, choose what fits your project, and hit Add to document . Build it piece by piece, exactly the way you work. Drop the result in the root of your repo and your agent finally knows what it's doing.
