# Get Started

## Docs

- [Quickstart Crew CLI](https://docs.smallest.ai/voice-agents/developer-guide/get-started/quickstart.md): Build, test, and deploy agent crews from the terminal.
- [Agents CLI](https://docs.smallest.ai/voice-agents/developer-guide/get-started/agents-cli.md): Create, inspect, and place calls from your Atoms agents without leaving the terminal.
- [What is Atoms Agent Crews SDK?](https://docs.smallest.ai/voice-agents/developer-guide/get-started/overview.md): The Python framework for real-time voice AI agents on Smallest AI. How the pieces fit together, the two versioning axes, and a working end-to-end sample.
- [Use Case Finder](https://docs.smallest.ai/voice-agents/developer-guide/get-started/use-case-finder.md): Find the canonical doc for every common voice-agent use case - single-prompt vs crew, phone vs web, knowledge base, tools, deployment, observability.
- [Error Handling in Agent Crews](https://docs.smallest.ai/voice-agents/developer-guide/get-started/error-handling.md): How exceptions in your crew code surface on the call - auto-emission, severity semantics, graceful fallbacks, and pre-deploy validation.
- [Prebuilt tools](https://docs.smallest.ai/voice-agents/developer-guide/get-started/prebuilt-tools.md): Use smallestai.tools to add prebuilt capabilities (web search, and more) to a crew agent in one line. Third-party libraries install as optional extras.
- [Agent Crew Core Concepts](https://docs.smallest.ai/voice-agents/developer-guide/get-started/agent-crew-core-concepts/overview.md): The fundamental building blocks of the Atoms Agent Crews SDK - nodes, sessions, events, and graphs.
- [Nodes](https://docs.smallest.ai/voice-agents/developer-guide/get-started/agent-crew-core-concepts/nodes.md): The fundamental building blocks of your agent's logic.
- [Events](https://docs.smallest.ai/voice-agents/developer-guide/get-started/agent-crew-core-concepts/events.md): The lifeblood of an Atoms application.
- [Graph](https://docs.smallest.ai/voice-agents/developer-guide/get-started/agent-crew-core-concepts/graphs.md): Connect nodes into event processing pipelines.
- [Sessions](https://docs.smallest.ai/voice-agents/developer-guide/get-started/agent-crew-core-concepts/sessions.md): The runtime universe for your agent.
