Unified AI Agent Instructions: Drive All Tools with AGENTS.md

Unified AI Agent Instructions: Drive All Tools with AGENTS.md

The Unified AI Agent Instructions skill provides a method to manage AI-agent instruction files within a repository, ensuring that a single canonical source, AGENTS.md, drives every compatible tool consistently, including GitHub Copilot. This set-up helps eliminate instruction drift across AI coding tools, providing a streamlined and centralized approach to managing agent instructions.

What this skill does

• Organises AI-agent instructions within repositories by establishing a single canonical file, AGENTS.md, as the primary source of truth.
• Supports integration across multiple AI coding tools such as Claude, Copilot, Cursor, Codex, and Gemini.
• Introduces thin per-tool shims like CLAUDE.md and GEMINI.md that reference the canonical AGENTS.md file.
• Optionally allows for path-scoped rules with a .github/instructions/ directory to further refine tool-specific guidance.
• Tackles the problem of instruction file drift, ensuring updates are uniformly reflected across tools.

Who it is for

• Developers and development teams using AI coding agents that require consistent instruction management.
• Teams maintaining repositories with multiple AI tools, seeking to eliminate redundant updates and inconsistencies.

Use cases

• Setting up instruction files for a new repository to support diverse AI coding tools simultaneously.
• Updating an existing repository’s AI-agent instructions to prevent divergence and maintain consistency across tools.
• Deciding what information to centralize in AGENTS.md versus tool-specific configuration files.

Technical details

• Compatible with various AI coding tools, including Claude Code, GitHub Copilot, Cursor, Codex, and Gemini CLI.
• Utilizes the AGENTS.md file placed at the root of the repository for universal instruction access.
• Supports inclusion of additional path-scoped rules for complex or specific use cases via .github/instructions/.
