Core Agent System and ReAct Loop

Overview and Purpose

The smolagents core agent system is implemented in src/smolagents/agents.py and centers on the MultiStepAgent abstract class. This class drives an iterative ReAct-style loop in which a language model proposes an action, the action is executed against a tool or sandbox, the result is appended to memory, and the loop continues until the model produces a final answer or a step limit is exceeded.

Two concrete subclasses ship in the library:

The loop is wired together with an AgentMemory instance that holds TaskStep, SystemPromptStep, PlanningStep, ActionStep, and FinalAnswerStep records. Each step is rendered into the next prompt via Jinja templates stored under src/smolagents/prompts/ (see code_agent.yaml and toolcalling_agent.yaml). Source: src/smolagents/agents.py:1-100

The library advertises this pattern in README.md as a lightweight, model- and tool-agnostic agent runtime backed by Hugging Face Inference Providers, LiteLLM, and MCP-compatible tool collections.

ReAct Loop Mechanics

The driver of the loop is MultiStepAgent.run, which performs the following sequence per iteration until termination:

1. Build a chat messages list from AgentMemory, applying the step_callbacks for any per-step hooks (used for Human-in-the-Loop flows; see examples/plan_customization/README.md).
2. Optionally invoke a PlanningStep to refresh a high-level plan before continuing.
3. Call the underlying Model to generate either a code blob (CodeAgent) or a structured tool-call (ToolCallingAgent).
4. Parse the response. For CodeAgent, extract_code_from_text / parse_code_blobs strip fences; for ToolCallingAgent, the model's native JSON tool-call surface is consumed.
5. Execute the action via the appropriate executor, producing an ActionOutput or ToolOutput dataclass defined in src/smolagents/agents.py:60-75.
6. Append an ActionStep (with timing, token usage, and observation) to memory.
7. If the action is a final answer, stop; otherwise loop.

This sequence is reflected directly in the prompt exemplars: Thought -> Code/Observation cycles for CodeAgent and Action/Observation cycles for ToolCallingAgent. Source: src/smolagents/prompts/code_agent.yaml:1-50 and src/smolagents/prompts/toolcalling_agent.yaml:1-80

Memory and Step Lifecycle

AgentMemory is the single source of truth for prompt construction. Step types are defined in src/smolagents/memory.py (imported from agents.py) and are inserted into memory by MultiStepAgent at well-defined moments:

Because memory is rendered at every iteration, community feedback has consistently flagged memory growth and persistence as an open concern. Issue #901 requests automatic consolidation after N interactions; issue #694 asks for built-in summarization to avoid context-window overflow; and issue #1216 requests first-class save/load of memory across sessions. Issue #945 proposes a pluggable memory backend (e.g., mem0). These concerns all map to the AgentMemory lifecycle described above. Source: src/smolagents/agents.py:80-130

For applications that need to inject prior chat history, issue #1579 tracks the recommended pattern: run the agent with reset=False so that pre-existing steps in AgentMemory are preserved across agent.run calls rather than re-initialized from scratch.

Configuration, Tools, and Customization

The loop is parameterized by several MultiStepAgent keyword arguments consumed throughout the loop body:

• tools and managed_agents: dictionaries passed to the prompt renderer so that each tool exposes a name, description, inputs, and output_type. Tool examples such as VisitWebpageTool, WikipediaSearchTool, and SpeechToTextTool are defined in src/smolagents/default_tools.py. Source: src/smolagents/default_tools.py:1-120
• planning_interval: integer step cadence at which a fresh PlanningStep is requested. Templates come from PlanningPromptTemplate (initial_plan, update_plan_pre_messages, update_plan_post_messages) defined in src/smolagents/agents.py:95-115.
• max_steps / step_callbacks: termination bound and per-step observers. step_callbacks is the supported extension point for Human-in-the-Loop patterns, as demonstrated by the interrupt_after_plan callback in examples/plan_customization/README.md, which inspects isinstance(memory_step, PlanningStep) to gate the loop and optionally mutate the plan in memory before resuming.
• executor_type: selects between LocalPythonExecutor and remote executors imported from src/smolagents/remote_executors.py (e.g., E2BExecutor, DockerExecutor, ModalExecutor, BlaxelExecutor). Community issue #2368 adds microsandbox to this list. Source: src/smolagents/agents.py:30-55
• prompt_templates: overrides for any of the YAML prompt sections, enabling structured-output variants such as structured_code_agent.yaml.

The structured variant in src/smolagents/prompts/structured_code_agent.yaml shows the JSON-encoded ReAct schema ({"thought": ..., "code": ...}) that CodeAgent uses when grammar/structured-output backends are configured.

Termination and Error Handling

The loop terminates in three ways, all surfaced as exceptions or return values:

These exception classes are imported from src/smolagents/utils.py at the top of agents.py and are used by the loop body to wrap failures into the ActionStep.error field rather than crashing the run. Source: src/smolagents/agents.py:25-45

Memory and State Management

Overview

In smolagents, memory and state management refers to how agents persist, replay, and project their interaction history back into model prompts. Every MultiStepAgent (including CodeAgent, ToolCallingAgent, and the structured variant) maintains an internal list of MemoryStep objects that grow each time the agent reasons, acts, or observes a tool result. The full step history is serialized into chat messages before each model call, giving the LLM the illusion of an ongoing conversation. Source: src/smolagents/agents.py.

Memory in the current version (v1.26.0) is in-memory only. There is no built-in serialization to disk or to external stores such as Redis, SQL, or mem0. The community has repeatedly requested persistence (issue #945), save/load helpers (#1216), summarization to control growth (#694, #901), and custom chat-history insertion for multi-turn chat (#1579). These are tracked as open feature requests rather than shipped behavior.

Memory Architecture

The agent's memory is a flat sequence of typed steps appended as the run progresses. The plan-customization example explicitly enumerates these step types:

Current memory contains N steps:
  1. TaskStep
  2. PlanningStep
  3. ActionStep
  4. ActionStep
  ...

Source: examples/plan_customization/README.md.

Each step carries metadata that is later flattened back into chat messages via write_memory_to_messages(). During the inner _generate_planning_step / _generate_action_step loops, the agent calls populate_template on the YAML prompt templates (planning.update_plan_pre_messages, planning.update_plan_post_messages) and concatenates the rendered messages with the live memory. Source: src/smolagents/agents.py.

    D --> G[memory.steps]
    F --> G
    G --> H[write_memory_to_messages]
    H --> I[Next LLM call]

The model output message, token usage, and parsed code action are written back onto the originating ActionStep (memory_step.model_output_message, memory_step.token_usage, memory_step.model_output). Source: src/smolagents/agents.py.

Memory-to-Message Projection

Before every model call, the agent converts its memory into chat messages. Two projection modes exist:

When a planning step is regenerated (e.g., after step_callback interrupts in the plan-customization example), the agent switches to summary mode by passing summary_mode=True to write_memory_to_messages. The code path is:

memory_messages = self.write_memory_to_messages(summary_mode=True)
plan_update_pre = ChatMessage(role=MessageRole.SYSTEM, content=[...])
plan_update_post = ChatMessage(role=MessageRole.USER, content=[...])
input_messages = [plan_update_pre] + memory_messages + [plan_update_post]

Source: src/smolagents/agents.py.

For structured-output code agents, the model output is appended with the closing code_block_tags[1] token to nudge future generations toward the same stop sequence, and this augmented string is stored on memory_step.model_output_message.content. Source: src/smolagents/agents.py.

Prompt Templates and State Carriers

The YAML prompt templates act as the canonical state descriptors that are spliced into memory messages:

• system_prompt establishes the Thought → Code → Observation loop and the final_answer convention. Source: src/smolagents/prompts/code_agent.yaml.
• planning.initial_plan and planning.update_plan_*_messages carry the facts survey + plan structure that is re-emitted whenever a planning step is regenerated. Source: src/smolagents/prompts/toolcalling_agent.yaml.
• managed_agent.task defines the contract for sub-agents that are delegated to from a parent agent, including required final_answer sections. Source: src/smolagents/prompts/code_agent.yaml.

The structured-code variant emits JSON envelopes with thought and code keys and uses the same planning surfaces. Source: src/smolagents/prompts/structured_code_agent.yaml.

Step Callbacks and Memory Inspection

The step_callbacks hook (used in examples/plan_customization/plan_customization.py) fires after each step is appended, letting external code inspect and modify memory before the next call. The example demonstrates:

print(f"Current memory contains {len(agent.memory.steps)} steps:")
for i, step in enumerate(agent.memory.steps):
    step_type = type(step).__name__
    print(f"  {i+1}. {step_type}")

Source: examples/plan_customization/README.md.

This is the only sanctioned way to mutate memory mid-run. There is no public save()/load() helper for memory — users wanting persistence must serialize agent.memory.steps themselves (issue #1216).

Known Limitations

The following limitations are reflected in the source and corroborated by community issues:

• No built-in summarization or truncation. The full step history is sent on every LLM call; only basic message removal is available. Long runs eventually exceed the context window. Source: src/smolagents/agents.py. Community: #694, #901.
• No pluggable persistence layer. Memory lives only on the agent instance. Community: #945, #1216.
• No first-class injection of prior chat history. Users who want to prepend past turns must manipulate memory.steps directly. Community: #1579.
• No memory-consolidation hook. Requests for a before_consolidation callback (for fingerprinting / observability) remain open. Community: #2129.
• No memory-poisoning guard. Requests to integrate OWASP-style protections for persistent memory are open. Community: #2332.

Tools, Models, and Execution Backends

smolagents is built around three orthogonal extension axes that an agent developer customizes at construction time: the tools an agent may invoke, the model that produces reasoning and actions, and the execution backend that runs any code the model emits. Because each axis is decoupled, a developer can mix, for example, a Tool-Calling model with a remote sandbox executor, or a Code Agent with locally defined tools, without touching the agent loop itself.

1. The Plugin Axes at a Glance

The agent constructor in src/smolagents/agents.py wires the three axes together. It imports the tool catalog from default_tools, the model registry from models, and a unified executor abstraction that supports both a local in-process interpreter and a set of remote sandboxed backends:

from .default_tools import TOOL_MAPPING, FinalAnswerTool
from .local_python_executor import BASE_BUILTIN_MODULES, LocalPythonExecutor, PythonExecutor
from .models import CODEAGENT_RESPONSE_FORMAT, MODEL_REGISTRY
from .remote_executors import BlaxelExecutor, DockerExecutor, E2BExecutor, ModalExecutor
from .tools import BaseTool, Tool, validate_tool_arguments

Source: src/smolagents/agents.py:1-50 Source: src/smolagents/agents.py:51-80

The following diagram summarizes how a single agent call flows through these layers:

flowchart LR
    U[User Task] --> A[MultiStepAgent.run]
    A --> M[Model.generate]
    M -- Action --> A
    A -- Code blob --> E{PythonExecutor}
    A -- Tool call --> T[Tool.forward]
    E -- Observation --> A
    T -- Observation --> A
    A --> F[final_answer]

Source: src/smolagents/agents.py:51-80 Source: src/smolagents/default_tools.py:1-40

Community discussion #145 ("Making this library async", issue #145) notes that most of this loop is network-bound, which is one reason execution backends are pluggable rather than hard-coded.

2. Tools: Authoring and Built-ins

A tool in smolagents is a Tool (or BaseTool) subclass that declares a name, a description, an inputs schema, an output_type, and a forward(...) method (src/smolagents/tools.py). For ordinary Python functions, the framework auto-derives a JSON schema from type hints and a Google-style docstring in src/smolagents/_function_type_hints_utils.py; the _parse_google_format_docstring and _convert_type_hints_to_json_schema helpers are the building blocks of that conversion.

class VisitWebpageTool(Tool):
    name = "webpage_visit"
    description = "Fetches and returns the content of a webpage as Markdown."
    inputs = {"url": {"type": "string", "description": "The url of the webpage to visit."}}
    output_type = "string"

    def forward(self, url: str) -> str:
        response = requests.get(url, timeout=20)
        markdown_content = markdownify(response.text).strip()
        return self._truncate_content(markdown_content, self.max_output_length)

Source: src/smolagents/default_tools.py:41-90

The bundled TOOL_MAPPING (src/smolagents/default_tools.py) ships with reference implementations that exercise several integration patterns:

Source: src/smolagents/default_tools.py:91-160 Source: src/smolagents/default_tools.py:161-230

SpeechToTextTool extends PipelineTool, which is the framework's adapter for transformers pipelines and overrides __new__ to inject the pre_processor_class and model_class (src/smolagents/default_tools.py). Custom tool authors normally only need a Tool subclass; they pick PipelineTool when they want Hugging Face model loading behavior for free.

3. Models: The Unified Client Surface

Models are registered through MODEL_REGISTRY in src/smolagents/models.py. The agent imports CODEAGENT_RESPONSE_FORMAT, ChatMessage, Model, agglomerate_stream_deltas, and parse_json_if_needed from that module, indicating a single chat-completion abstraction regardless of vendor. Community request #449 ("Add LlamaCppModel Support", issue #449) is explicitly about extending this registry with another backend.

The three shipped prompt variants in src/smolagents/prompts/ drive different model behaviors:

• code_agent.yaml instructs the model to emit Python code blobs fenced with {{code_block_opening_tag}} ... {{code_block_closing_tag}}.
• structured_code_agent.yaml forces a JSON {"thought": "...", "code": "..."} envelope so untrusted code extraction is unnecessary.
• toolcalling_agent.yaml requests structured tool-call JSON via the final_answer action and the standard Action/Observation cycle.

Source: src/smolagents/prompts/code_agent.yaml:1-40 Source: src/smolagents/prompts/structured_code_agent.yaml:1-40 Source: src/smolagents/prompts/toolcalling_agent.yaml:1-40

ChatMessageStreamDelta and agglomerate_stream_deltas (src/smolagents/models.py) allow streaming model output to be reassembled before downstream parsing, which is what makes both code-block and JSON-typed parsers possible.

4. Execution Backends: Local and Remote

The third axis is where the agent's emitted code actually runs. The base class PythonExecutor lives in src/smolagents/local_python_executor.py, with LocalPythonExecutor and BASE_BUILTIN_MODULES exported alongside it. LocalPythonExecutor is an in-process interpreter that sandboxes imports against BASE_BUILTIN_MODULES and validates every assignment, call, and attribute access against a static set of allowed operations.

# from src/smolagents/agents.py
from .local_python_executor import (
    BASE_BUILTIN_MODULES,
    LocalPythonExecutor,
    PythonExecutor,
    fix_final_answer_code,
)

Source: src/smolagents/agents.py:31-50

For deployments that require stronger isolation, src/smolagents/remote_executors.py provides four pluggable implementations imported directly in agents.py:

• E2BExecutor — runs inside an E2B microVM sandbox.
• DockerExecutor — runs inside a local Docker container.
• ModalExecutor — runs on Modal serverless infrastructure.
• BlaxelExecutor — runs on the Blaxel platform.

Source: src/smolagents/agents.py:51-70

The executor choice is made at agent construction time (executor=...) so the agent loop in agents.py can be backend-agnostic. Community issue #2368 ("Executor support for microsandbox", issue #2368) demonstrates the extension pattern: a new executor subclass implements the PythonExecutor interface and is registered for selection. Issue #2372 (#2372) points out that evaluate_python_code's parameters (authorized_imports, max_print_outputs_length, etc.) must stay documented in lockstep with the executor interface, since the same function powers both the local and remote paths.

5. Putting the Three Axes Together

A typical minimal configuration binds one value from each axis:

from smolagents import CodeAgent, InferenceClientModel
from smolagents.default_tools import VisitWebpageTool

agent = CodeAgent(
    tools=[VisitWebpageTool()],
    model=InferenceClientModel(),
    executor=LocalPythonExecutor(),  # or E2BExecutor(), DockerExecutor(), ...
)
agent.run("Summarize the latest release notes on https://huggingface.co")

Source: src/smolagents/agents.py:51-80 Source: src/smolagents/local_python_executor.py:1-40 Source: src/smolagents/default_tools.py:41-90

The same agent class can be retargeted to a Tool-Calling model by switching the prompt YAML and the model= argument, and can be hardened for production by switching executor= to E2BExecutor or DockerExecutor. None of those choices require modifying the agent loop, which is the design intent behind the three-axis separation.

Deployment, CLI, UI, Security, and Extensibility

smolagents exposes four concerns that sit on top of the core agent loop and let a notebook agent become a shipped product: serializing a MultiStepAgent to disk or the Hub, presenting it through a CLI or a Gradio UI, isolating the Python code it writes, and extending it with new tools, prompts, and models. Each of these layers is intentionally small so that the framework stays composable.

Deployment and Serialization

The on-disk layout produced by agent.save() is deterministic and self-contained, which is what makes the framework loadable from another process and publishable as a Space. The implementation walks the agent's tools, managed_agents, and prompt_templates, emitting one Python file per tool, a prompts.yaml, an agent.json description, and a recursive managed_agents/ subtree, plus a requirements.txt listing the modules the tools import (Source: src/smolagents/agents.py). When the agent is pushed with agent.push_to_hub(), the same directory is wrapped with an app.py that serves a Gradio interface, so a Space can be generated directly from a Python process without manual authoring (Source: src/smolagents/agents.py).

Prompt rendering goes through populate_template, which uses Jinja2 with StrictUndefined so that a missing template variable raises immediately instead of silently producing an empty string (Source: src/smolagents/agents.py). The on-disk prompts.yaml is written with yaml.safe_dump and default_style="|" to preserve block-literal multi-line strings (Source: src/smolagents/agents.py).

flowchart LR
    A[CodeAgent / ToolCallingAgent] -->|save| B[output_dir]

    B --> E[agent.json]
    B --> F[managed_agents/]
    B -->|push_to_hub| G[HuggingFace Space]
    G --> H[app.py + Gradio UI]

Client Interfaces: CLI and Gradio UI

Two thin front-ends let non-Python users interact with a saved agent. The smolagents command-line entry point lives in src/smolagents/cli.py and is the canonical way to load an agent directory and run a task from the terminal. Because this path is synchronous and most agent work is network-bound, community discussion about an asynchronous API is tracked in #145.

The interactive surface is a Gradio app. The app.py emitted by push_to_hub() is generated by create_agent_gradio_app_template in src/smolagents/utils.py, while src/smolagents/gradio_ui.py provides the reusable chat-style component used by that template. This UI layer is also where human-in-the-loop workflows land: community pattern #52 describes pausing a step so a human can supply missing information or approve a sensitive tool call before it executes.

Security and Sandboxed Execution

Because the default CodeAgent writes and executes Python, isolation is not optional. smolagents splits this responsibility across two layers that are referenced from the agent constructor: import allow-listing in the local executor and OS-level isolation through pluggable remote executors. Tool argument validation runs before execution through validate_tool_arguments in src/smolagents/tools.py, which is imported alongside the executors in src/smolagents/agents.py.

Demand for additional sandboxes is active: #2368 (closed) proposed libkrun/microsandbox for lightweight local isolation, which signals that the executor abstraction is the intended extension point. Memory poisoning is a separate risk called out in #2332, where the suggestion is to wrap AgentMemory with an OWASP-style guard rather than rely on prompt engineering alone.

Extensibility

The framework is extended at three layers.

Tools. A new tool subclasses Tool and declares a name, description, and JSON-schema inputs. Tool schemas can be derived from typed Python functions by _function_type_hints_utils.get_json_schema, which parses Google-style docstrings, raises DocstringParsingException when an argument is undocumented, and supports (choices: [...]) to mark enum fields (Source: src/smolagents/_function_type_hints_utils.py). The default-tool catalog in src/smolagents/default_tools.py — VisitWebpageTool, WikipediaSearchTool, SpeechToTextTool — shows the canonical pattern of declaring name, description, inputs, and output_type and raising ImportError when optional dependencies are missing.

Prompts. All prompt templates live in src/smolagents/prompts/ as YAML: code_agent.yaml, structured_code_agent.yaml, and toolcalling_agent.yaml. They are loaded into agent.prompt_templates and expose slots for the system prompt, planning step, managed-agent dispatch, and final answer (Source: src/smolagents/prompts/code_agent.yaml, Source: src/smolagents/prompts/toolcalling_agent.yaml). The PlanningPromptTemplate, ManagedAgentPromptTemplate, and FinalAnswerPromptTemplate TypedDicts in src/smolagents/agents.py document the keys each slot accepts.

Models and observability. The model layer registers backends through MODEL_REGISTRY, so adding a provider means subclassing Model and registering it; #449 requests a LlamaCppModel and #1848 requests Anthropic Claude "agent skills". Observability is handled by src/smolagents/monitoring.py, which exposes TokenUsage, AgentLogger, Monitor, and LogLevel; the v1.25.0 release notes document an MLflow integration built on top of this surface.
