| 1 | +# Agents |
| 2 | + |
| 3 | +## Schema Hierarchy |
| 4 | + |
| 5 | +The Atomic Agents framework uses Pydantic for schema validation and serialization. All input and output schemas follow this inheritance pattern: |
| 6 | + |
| 7 | +``` |
| 8 | +pydantic.BaseModel |
| 9 | + └── BaseIOSchema |
| 10 | + ├── BaseAgentInputSchema |
| 11 | + └── BaseAgentOutputSchema |
| 12 | +``` |
| 13 | + |
| 14 | +### BaseIOSchema |
| 15 | + |
| 16 | +The base schema class that all agent input/output schemas inherit from. |
| 17 | + |
| 18 | +```{eval-rst} |
| 19 | +.. py:class:: BaseIOSchema |
| 20 | +
|
| 21 | + Base schema class for all agent input/output schemas. Inherits from :class:`pydantic.BaseModel`. |
| 22 | +
|
| 23 | + All agent schemas must inherit from this class to ensure proper serialization and validation. |
| 24 | +
|
| 25 | + **Inheritance:** |
| 26 | + - :class:`pydantic.BaseModel` |
| 27 | +``` |
| 28 | + |
| 29 | +### BaseAgentInputSchema |
| 30 | + |
| 31 | +The default input schema for agents. |
| 32 | + |
| 33 | +```{eval-rst} |
| 34 | +.. py:class:: BaseAgentInputSchema |
| 35 | +
|
| 36 | + Default input schema for agent interactions. |
| 37 | +
|
| 38 | + **Inheritance:** |
| 39 | + - :class:`BaseIOSchema` → :class:`pydantic.BaseModel` |
| 40 | +
|
| 41 | + .. py:attribute:: chat_message |
| 42 | + :type: str |
| 43 | +
|
| 44 | + The message to send to the agent. |
| 45 | +
|
| 46 | + Example: |
| 47 | + >>> input_schema = BaseAgentInputSchema(chat_message="Hello, agent!") |
| 48 | + >>> agent.run(input_schema) |
| 49 | +``` |
| 50 | + |
| 51 | +### BaseAgentOutputSchema |
| 52 | + |
| 53 | +The default output schema for agents. |
| 54 | + |
| 55 | +```{eval-rst} |
| 56 | +.. py:class:: BaseAgentOutputSchema |
| 57 | +
|
| 58 | + Default output schema for agent responses. |
| 59 | +
|
| 60 | + **Inheritance:** |
| 61 | + - :class:`BaseIOSchema` → :class:`pydantic.BaseModel` |
| 62 | +
|
| 63 | + .. py:attribute:: chat_message |
| 64 | + :type: str |
| 65 | +
|
| 66 | + The response message from the agent. |
| 67 | +
|
| 68 | + Example: |
| 69 | + >>> response = agent.run(input_schema) |
| 70 | + >>> print(response.chat_message) |
| 71 | +``` |
| 72 | + |
| 73 | +### Creating Custom Schemas |
| 74 | + |
| 75 | +You can create custom input/output schemas by inheriting from `BaseIOSchema`: |
| 76 | + |
| 77 | +```python |
| 78 | +from pydantic import Field |
| 79 | +from typing import List |
| 80 | +from atomic_agents.lib.base.base_io_schema import BaseIOSchema |
| 81 | + |
| 82 | +class CustomInputSchema(BaseIOSchema): |
| 83 | + chat_message: str = Field(..., description="User's message") |
| 84 | + context: str = Field(None, description="Optional context for the agent") |
| 85 | + |
| 86 | +class CustomOutputSchema(BaseIOSchema): |
| 87 | + chat_message: str = Field(..., description="Agent's response") |
| 88 | + follow_up_questions: List[str] = Field( |
| 89 | + default_factory=list, |
| 90 | + description="Suggested follow-up questions" |
| 91 | + ) |
| 92 | + confidence: float = Field( |
| 93 | + ..., |
| 94 | + description="Confidence score for the response", |
| 95 | + ge=0.0, |
| 96 | + le=1.0 |
| 97 | + ) |
| 98 | +``` |
| 99 | + |
| 100 | +## Base Agent Configuration |
| 101 | + |
| 102 | +### BaseAgentConfig |
| 103 | + |
| 104 | +The configuration class for BaseAgent that defines all settings and components. |

| 264 | +### Examples |
| 265 | + |
| 266 | +#### Basic Synchronous Interaction |
| 267 | + |
| 268 | +```python |
| 269 | +# Create input and get response |
| 270 | +user_input = agent.input_schema(chat_message="Tell me about quantum computing") |
| 271 | +response = agent.run(user_input) |
| 272 | + |
| 273 | +print(f"Assistant: {response.chat_message}") |
| 274 | +``` |
| 275 | + |
| 276 | +#### Streaming Response |
| 277 | + |
| 278 | +```python |
| 279 | +import asyncio |
| 280 | + |
| 281 | +async def stream_chat(): |
| 282 | + # Initialize with AsyncOpenAI for streaming |

| 294 | + print() |
| 295 | + |
| 296 | +asyncio.run(stream_chat()) |
| 297 | +``` |
| 298 | + |
| 299 | +#### Using Tools |
| 300 | + |
| 301 | +```python |
| 302 | +# Create agent with tools |
| 303 | +agent = BaseAgent( |
| 304 | + config=BaseAgentConfig( |
| 305 | + client=client, |
| 306 | + model="gpt-4", |
| 307 | + tools=["calculator", "searxng_search"], |

| 317 | +response = agent.run( |
| 318 | + agent.input_schema( |

| 323 | + |
| 324 | +#### Custom Memory and System Prompt |
| 325 | + |
| 326 | +```python |
| 327 | +from atomic_agents.lib.components.system_prompt_generator import SystemPromptGenerator |
| 328 | + |

| 330 | +generator = SystemPromptGenerator( |
| 331 | + background=["You are a helpful AI assistant specializing in technical support."], |
| 332 | + steps=[ |
| 333 | + "1. Understand the technical issue", |
| 334 | + "2. Ask clarifying questions if needed", |
| 335 | + "3. Provide step-by-step solutions" |
| 336 | + ] |
| 337 | +) |
| 338 | + |
| 339 | +# Create agent with custom memory and prompt |
| 340 | +agent = BaseAgent( |
| 341 | + config=BaseAgentConfig( |
| 342 | + client=client, |
| 343 | + model="gpt-4", |
| 344 | + memory=AgentMemory(), |
