huggingface / smolagents · Architecture

GitHub metadata records Python as the primary language, and the repository's own description calls it smolagents, 'a barebones library for agents that think in code'.

The analyzer summary counts 185 analyzed files organized around docs, examples, src and tests, including 28 test-like files, and the subsystem records flag docs, src and tests as likely subsystems.

Reported top-level file counts: docs 81, examples 34, src 21, tests 28, .github 10, plus 11 root-level files.

• src/smolagents holds files such as cli.py and vision_web_browser.py, both flagged as likely entrypoints.
• examples/ holds runnable scripts with per-example requirements manifests, such as examples/async_agent/requirements.txt and examples/open_deep_research/requirements.txt.

Ten entrypoints are reported: eight files carry an explicit __main__ execution guard — examples/structured_output_tool.py, src/smolagents/cli.py, src/smolagents/vision_web_browser.py, examples/open_deep_research/app.py, examples/open_deep_research/run.py, examples/open_deep_research/run_gaia.py, examples/plan_customization/plan_customization.py, examples/smolagents_benchmark/run.py — and examples/async_agent/main.py plus examples/server/main.py are candidates by filename heuristic.

The summary names examples/structured_output_tool.py as the apparent main starting place, while a teaching claim points to examples/async_agent/main.py. The reconstruction reports 90 bounded execution paths; ten are recorded individually here.

Of the recorded paths:

• both examples/async_agent/main.py paths stop at Route and Starlette;
• the three examples/open_deep_research/app.py paths stop at create_agent, GradioUI and demo.launch;
• the five examples/open_deep_research/run.py paths stop at load_dotenv, login, os.getenv and threading.Lock.

All ten end the same way: terminal reason 'unresolved_boundary', no truncation, no detected cycle.

All 20 module-role records in the packet are analyzer inferences drawn from static resolved call degree and entrypoint membership; none is confirmed by runtime evidence.

• src/smolagents/local_python_executor.py has the highest call degree listed: 195 incoming and 190 outgoing calls.
• src/smolagents/models.py (60 in / 66 out) and src/smolagents/agents.py (16 in / 80 out) are service/core candidates.
• src/smolagents/utils.py (56 in / 8 out) and src/smolagents/_function_type_hints_utils.py (24 in / 18 out) are also core candidates.
• Further src/smolagents candidates: tools.py (5/24), remote_executors.py (7/22), monitoring.py (17/1), memory.py (16/1), gradio_ui.py (9/9), agent_types.py (10/5), serialization.py (10/4).
• In examples/open_deep_research/scripts: mdconvert.py (30/29), gaia_scorer.py (12/12), run_agents.py (4/4).
• Entry/orchestration candidates: src/smolagents/cli.py, src/smolagents/vision_web_browser.py, examples/open_deep_research/run_gaia.py, examples/plan_customization/plan_customization.py.
• tests/test_agents.py is the highest-degree test module (89 in / 89 out).

Most recorded edges leave the analyzable area: 6888 of 7633 static relations are external or unresolved, and only 745 resolve to local targets.

The recorded paths stop at:

• Route and Starlette, reached from examples/async_agent/main.py; starlette is also a declared runtime dependency of that example;
• create_agent, GradioUI and demo.launch, reached from examples/open_deep_research/app.py — the packet does not establish where these targets are defined;
• load_dotenv, login, os.getenv and threading.Lock, reached from examples/open_deep_research/run.py.

Each of the ten recorded paths terminates because its next target is external or unresolved rather than another analyzed module.

The analyzer also documents that reflection, runtime dependency injection, dynamic imports, monkey-patching, generated code, framework runtime wiring and dynamic dispatch are not resolved.

Recorded relations divide into 6700 calls and 933 imports (7633 total); the reconstruction separately reports 615 resolved static call relations, a figure the packet does not reconcile with the 745 local edges.

Manifest evidence:

• examples/async_agent/requirements.txt declares smolagents, starlette, anyio and uvicorn as runtime dependencies — the example lists the library itself.
• examples/open_deep_research/requirements.txt yields records including anthropic (>=0.37.1), openai (>=1.52.2), transformers (>=4.46.0) and torch (>=2.2.2).
• Records cover requirements-style manifests only: pyproject.toml dependency tables are not parsed, so the src package's own dependencies are absent.

Internal coupling: high incoming counts on local_python_executor.py (195) and models.py (60) suggest, by inference, that much of src/smolagents is called from elsewhere, but the packet does not list the callers.

How the pieces are wired while the program runs is not established here: the analyzer does not resolve framework runtime wiring, dynamic dispatch, reflection, dynamic imports, monkey-patching, generated code or runtime dependency injection.

Also outside this analysis:

• installation and run/build behavior is only partially inferred, and installation commands are not verified;
• README-derived statements are line-based extractions and count as author claims at best;
• the manifest's capability fields describe the analyzer itself, not the repository, and are excluded from evidence;
• tests exist (28 test-like files per the summary), but what they verify at runtime is not established.

Finally, 6888 of 7633 relations are external or unresolved, so a missing link in this data is not evidence that two parts are independent.

README.md, pyproject.toml and LICENSE are classified as project-level important files.

A teaching claim in the packet recommends starting from manifests and important symbols, then tracing the bounded execution paths and inspecting the unresolved boundaries before changing code.
