# A2A Protocol Skill
Implementation of the Agent2Agent (A2A) Protocol for inter-agent communication.
## What it does
- **Agent Discovery** via Agent Cards
- **Send Messages** to remote agents
- **Task Management** (submit, check status, get results)
- **Streaming** via Server-Sent Events (SSE)
- **Authentication** support (API keys, Bearer tokens)
## Installation
```powershell
# Install Python dependencies
pip install requests sseclient-py
```
## Usage
### Register Your Agent
```powershell
.\a2a.ps1 -Action register -Name "MyAgent" -Description "Research agent" -Capabilities "research,analysis" -Endpoint "https://my-agent.com/a2a"
```
### Get Agent Card
```powershell
.\a2a.ps1 -Action card -AgentId "uuid-of-agent"
```
### Send Message
```powershell
.\a2a.ps1 -Action send -ToAgent "target-agent-uuid" -Content "Hello agent!"
```
### Submit Task
```powershell
.\a2a.ps1 -Action task -ToAgent "target-agent-uuid" -Task "Research quantum computing"
```
### Check Task Status
```powershell
.\a2a.ps1 -Action status -TaskId "task-uuid"
```
### List Remote Agents
```powershell
.\a2a.ps1 -Action list -RegistryUrl "https://registry.agentlink.io"
```
## A2A Concepts
- **Agent Card**: JSON describing agent capabilities (name, endpoint, methods)
- **Client Agent**: Agent that sends tasks
- **Remote Agent**: Agent that receives and processes tasks
- **Task**: Work request with ID, status, and result
- **Message**: Direct communication between agents
## API Reference
```
POST /a2a/agents/register - Register agent
GET /a2a/agents/{id} - Get agent info
GET /a2a/agents/{id}/card - Get Agent Card
POST /a2a/messages - Send message
POST /a2a/tasks - Submit task
GET /a2a/tasks/{id} - Get task status
GET /a2a/tasks/{id}/result - Get task result
```
## Examples
### Python Usage
```python
from a2a import A2AClient
client = A2AClient("https://remote-agent.com/a2a", api_key="your-key")
# Send message
client.send_message("target-agent-id", "Hello!")
# Submit task
task_id = client.submit_task("target-agent-id", "Do X")
result = client.get_result(task_id)
```
## Requirements
- Python 3.8+
- requests library
- sseclient-py (for streaming)
