AGENTS.md Tutorial: Open Standard for Coding-Agent Guidance in Repositories
May 11, 2026 ยท View on GitHub
Learn how to use
agentsmd/agents.mdto define a clear, portable instruction contract for coding agents across projects and tools.
Why This Track Matters
AGENTS.md is a simple standard for expressing coding-agent instructions directly in repositories, reducing ambiguity and improving cross-tool consistency.
This track focuses on:
- creating practical AGENTS.md files quickly
- designing stable instruction sections and conventions
- rolling out repository-wide standards for agent operations
- maintaining guidance quality over time
Current Snapshot (auto-updated)
- repository:
agentsmd/agents.md - stars: about 21.2k

Chapter Guide
| Chapter | Key Question | Outcome |
|---|---|---|
| 01 - Getting Started | How do I add a first AGENTS.md file that actually helps? | Working baseline |
| 02 - Section Design and Instruction Quality | Which sections create the most value for coding agents? | Better instruction structure |
| 03 - Tool-Agnostic Portability Patterns | How do I keep instructions portable across agent tools? | Cross-tool consistency |
| 04 - Repository Structure and Scope Strategy | How do I scope guidance for monorepos and subprojects? | Better hierarchy control |
| 05 - Testing, Linting, and CI Alignment | How do I make AGENTS.md enforce real quality gates? | Stronger execution discipline |
| 06 - Team Rollout and Adoption Playbook | How do teams adopt this without slowing delivery? | Rollout plan |
| 07 - Governance, Versioning, and Drift Control | How do I keep instructions current as code evolves? | Lower guidance drift |
| 08 - Ecosystem Contribution and Standard Evolution | How do I contribute back to the standard effectively? | Contributor readiness |
