AI Coding Conventions Ecosystem
CONVENTIONS.md sits alongside several closely related AI coding conventions. CLAUDE.md is used by Claude Code for repository memory. .cursor/rules and .cursorrules are used by Cursor. .github/copilot- instructions.md is used by GitHub Copilot. Each follows a similar pattern: a Markdown or text file describing repository-specific rules that gets injected into the AI assistant prompt context. CONVENTIONS.md is the most tool-agnostic option and is widely adopted across multiple AI coding agents.
