About A2AS Certificates

A2AS certificates are declarative manifests for agent behavior. They describe what an agent is designed to do:

• AI level: agents, models, tools, resources
• APP level: imports, functions, variables
• OS level: files, networks, processes

Certificates are human-readable and machine-readable, and can be used as a transparency and security artifact.

The A2AS standard is a project from the A2AS.org initiative led by experts from big tech and security companies.

Benefits For This Project

This A2AS certificate can help to:

• Make it easier for contributors to see what the agent does
• Increase trust in your agent by making its behavior explicit
• Grow adoption with security-conscious and enterprise users

What This PR Does

This PR doesn't change any code:

• Only adds a2as.yaml to the repository root
• Aligns the certificate with the current agent logic
• Does not modify agent code, prompts, or configuration

Optional Next Steps

When the agent changes, the A2AS certificate is expected to be updated.

A2AS project maintainers can help with updating the certificate as your agent evolves.
