README.md files are for humans: quick starts, project descriptions, and contribution guidelines.

AGENTS.md complements this by containing the extra, sometimes detailed context coding agents need: build steps, tests, and conventions that might clutter a README or aren’t relevant to human contributors.

This:

• Give agents a clear, predictable place for instructions.
• Keep READMEs concise and focused on human contributors.
• Provide precise, agent-focused guidance that complements existing README and docs.

Rather than introducing another proprietary file, we chose a name and format that could work for anyone. If you’re building or using coding agents and find this helpful, feel free to adopt it.
