# `ADK.A2A.AgentCard`
[🔗](https://github.com/zeroasterisk/adk-elixir/blob/main/lib/adk/a2a/agent_card.ex#L2)

Generates an A2A Agent Card from an ADK agent.

The Agent Card is served at `/.well-known/agent.json` and describes
the agent's capabilities, skills, and endpoint URL.

This module bridges ADK agents to the `A2A.AgentCard` protocol type
from the [a2a](https://github.com/zeroasterisk/a2a-elixir) package.

# `from_agent`

```elixir
@spec from_agent(
  ADK.Agent.t(),
  keyword()
) :: map()
```

Generate an A2A Agent Card map from an ADK agent.

## Options
  - `:url` — the agent's A2A endpoint URL (required)
  - `:version` — agent version (default "1.0.0")
  - `:provider` — provider info map
  - `:capabilities` — optional capabilities overrides

## Examples

    iex> agent = ADK.Agent.LlmAgent.new(name: "helper", model: "test", instruction: "Help", description: "A helpful agent", tools: [])
    iex> card = ADK.A2A.AgentCard.from_agent(agent, url: "http://localhost:4000/a2a")
    iex> card["name"]
    "helper"

# `to_a2a_card`

```elixir
@spec to_a2a_card(
  ADK.Agent.t(),
  keyword()
) :: A2A.AgentCard.t()
```

Build an `A2A.AgentCard` struct from an ADK agent.
