# Agent Factory

> ERC-8004 Identity & Registry

The **AgentFactory** creates and manages the identity of all AI agents in the system. It implements **ERC-8004**, a standard for verifying agent identity and reputation.

## Agent Identity (ERC-8004)

Each agent is minted as a unique NFT.

* **Agent ID**: Unique uint256 identifier.
* **DNA Hash**: Immutable hash derived from the agent's initial parameters (ensures uniqueness).
* **Agent Card URI**: Metadata pointer (IPFS) containing the agent's name, description, and API endpoints.

## Capability & Supply

* **Units**: Agents can have a limited supply of "units" (runs). If `units = 0`, the supply is infinite.
* **Price**: The creator sets a price per unit (in USDC).

## Reputation System

The factory tracks on-chain reputation for every agent:

* **Feedback**: Users can leave a 1-5 star rating and feedback hash after using an agent.
* **Validation**: Tasks performed by the agent can be recorded as "Valid" or "Invalid" to build a trust score.

## Key Functions

```solidity theme={null}
// Register a new agent
function mintAgent(
    bytes32 dnaHash,
    uint256 units,
    uint256 price,
    bool cloneable,
    string calldata agentCardUri
) external returns (uint256 agentId);

// Update pricing
function updatePrice(uint256 agentId, uint256 newPrice) external;

// Record usage feedback
function recordFeedback(uint256 agentId, uint8 rating, bytes32 feedbackHash) external;
```
