AGENTS.md plus scoped .instructions.md files, custom agents, skills, and hooks designed for GitHub's autonomous Coding Agent.
One AGENT.md file as the single source of truth, with symlinks to CLAUDE.md, .cursorrules, .windsurfrules, and copilot-instructions.md.
A deliberately tiny CLAUDE.md (under 50 lines) paired with aggressive /clear usage, plan mode, and letting the codebase speak for itself.
Separates what to build (SPEC.md) from how the AI should work (CLAUDE.md). Specs define features and constraints, CLAUDE.md defines workflow and conventions.
Frontend-optimized AI config covering design system tokens, component conventions, and testing patterns across Cursor, Copilot, and Claude Code simultaneously.
Repository-wide copilot-instructions.md plus path-specific .instructions.md files with applyTo frontmatter for scoped guidance.
Scoped .cursor/rules/*.mdc files with glob patterns, auto-attach triggers, and file references. The modern Cursor project setup.
A .windsurfrules file at project root that configures Cascade's agentic workflow with stack details, conventions, and anti-patterns.
A lean CLAUDE.md that uses @path/to/file imports to pull in docs, architecture decisions, and git workflows on demand rather than inline.
Root-level CLAUDE.md with per-package CLAUDE.md files that Claude auto-loads when working in subdirectories. Works with Turborepo, Nx, and pnpm workspaces.
Full .claude/ directory with auto-discovered skills, slash commands, subagents, lifecycle hooks, and plugin support for advanced workflows.
A single CLAUDE.md file under 200 lines with project context, commands, and conventions. The Anthropic-recommended starting point.
