# Concepts

> This page gives you an overview of the core concepts of Agent Builder

## Task Types

### AI Task

* Handles intelligent processing using AI capabilities.
  ```mermaid theme={null}
  graph LR
      Input --> AI[AI Processing] --> Output
  ```

### Human Task

* Manages human interventions and approvals.
  ```mermaid theme={null}
  graph LR
      Request --> Human[Human Decision] --> Response
  ```

### App Task

* Integrates with external tools and applications.
  ```mermaid theme={null}
  graph LR
      Data --> App[Tool Integration] --> Result
  ```

### Coder Task

* Executes custom code artifacts.
  ```mermaid theme={null}
  graph LR
      Input --> Code[Code Execution] --> Output
  ```

## Parameter Types

### Input Parameters

Data that flows into tasks:

* Basic types (string, number, boolean)
* Complex types (array, object)
* Special types (artifacts)

### Output Parameters

Results produced by tasks:

* Basic data types
* File outputs
* Media outputs
* Structured data

## Assignment Rules

### Rule Types

1. **Exception**
   * Error handling
   * Special cases

2. **Human Feedback**
   * Approvals
   * Reviews

### Assignment Types

1. **User Assignment**
   * Direct user allocation
   * Individual responsibility

2. **Team Assignment**
   * Group allocation
   * Round-robin distribution

## Workflow Concepts

### Dependencies

```mermaid theme={null}
graph TD
    A[Task A] --> B[Task B]
    B --> C[Task C]
```

* Sequential execution
* Parallel processing
* Conditional flows

### Error Policies

1. **RAISE**
   * Stop execution
   * Report error

2. **IGNORE**
   * Continue execution
   * Log warning

3. **RETRY**
   * Attempt recovery
   * Configurable attempts

## Best Practices Overview

1. **Task Design**
   * Clear naming
   * Proper description
   * Error handling

2. **Parameter Configuration**
   * Type selection
   * Validation rules
   * Default values

3. **Assignment Setup**
   * Clear responsibilities
   * Backup assignees
   * Team distribution
