Can other agents read your agent card?

An agent introduces itself with a card published at /.well-known/agent-card.json. It is the only document another agent reads before deciding to call you. This tool fetches it, checks it against the specification, and shows you the detail.

How to fix it

capabilitiesAn object declaring the optional A2A features the agent supports. Declaring them all false is a valid and honest answer.
```
"capabilities": {"streaming": false, "pushNotifications": false}
```
defaultInputModesThe media types the agent accepts, across all its skills.
```
"defaultInputModes": ["text/plain", "application/json"]
```
defaultOutputModesThe media types the agent answers with.
```
"defaultOutputModes": ["text/plain", "application/json"]
```
supportedInterfaces[0].protocolVersionThe A2A version this interface speaks. Use the latest minor version of your major one.
```
"protocolVersion": "1.0"
```
supportedInterfaces[1].protocolVersionThe A2A version this interface speaks. Use the latest minor version of your major one.
```
"protocolVersion": "1.0"
```
