smolagents

smolagents is a leading agent framework in the 2026 AI agent engineering landscape (28.1k★).

When to use this skill

• ~1k-line core: CodeAgent writes actions as Python code instead of JSON tool calls
• ToolCallingAgent for classic JSON tool calling when preferred
• Sandboxed execution: local, Docker, E2B, WebAssembly executors
• Model-agnostic: InferenceClientModel, LiteLLM, Transformers, OpenAI/Azure, Bedrock
• Tool sharing/loading via HF Hub; MCP tool import
• Multi-agent via managed_agents; CLI entrypoints smolagent/webagent
• Ecosystem overlap: agent-tool-routing covers registry concepts; smolagents' code-as-action is a distinct execution paradigm not covered anywhere

Installation

pip install "smolagents[toolkit]"
