Groundrules

About

Every AI coding agent operates from an instruction file, such as AGENTS.md, CLAUDE.md, or a system prompt. These are often duplicated and frequently outdated. Groundrules provides a visual editor to construct them: you can drag and drop proven components like conventions, workflows, and strict rules with validation checks onto a workspace. Compile the design into any format your tools require, and then Test Drive it across more than twelve active models, including Claude, GPT, Gemini, and Grok, to confirm the agent follows instructions before you finalize the file. The core builder is available at no cost.
