# A2A Agent Card

Category: Agent readiness
Version: 1.0.0

## Goal
Publish an A2A Agent Card so other agents can discover your agent-to-agent capabilities and supported interfaces.

## Issue
The audited site did not satisfy the A2A Agent Card readiness check.

## Fix
Publish /.well-known/agent-card.json describing your agent: `name`, `description`, `endpoints`, `version`, and a complete `supportedInterfaces` array with the protocols and message types you accept. Include a `capabilities` block so calling agents can negotiate, and keep the URL stable across deploys — agents cache discovery responses.

## Validation
- Confirm content types, payload shape, and discoverability from the public web surface.
- Verify against fresh public evidence, not only local source changes.
- Re-run the relevant isitready.dev scan before claiming the issue is closed.
