Type annotations for boto3 SFN 1.43.7 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes. If you use boto3 Step Functions in a Python project with a type checker or IDE that supports stubs, this package is worth installing. It has low install friction, no security vulnerabilities, an active maintenance signal, and a permissive MIT license. The only caveat is a known PyCharm performance issue with Literal overloads (documented in the package), which can be mitigated by using types-boto3-lite instead.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; boto3 must be installed separately in your project.
- Low friction—a pure stub package with only typing-extensions as a runtime dependency.
- Actively maintained with recent releases; last commit 2026-06-22.

What it is and what it does
This package provides type stub annotations for the boto3 Step Functions service, compatible with boto3 1.43.7. It was generated using mypy-boto3-builder 8.12.0 and works with mypy, pyright, VSCode, PyCharm, Emacs, Sublime Text, and other tools that support Python type hints. The stubs enable static type checking and IDE code completion without requiring explicit type annotations in your boto3 code—you write boto3 calls normally and the type checker understands the API surface automatically.
The package is a stub-only distribution (no runtime code), so it adds minimal overhead. It includes annotations for the SFNClient, paginators, waiters, and type definitions specific to Step Functions operations. Installation is straightforward via pip, and the package is actively maintained with recent releases.
Use it for
- Enable IDE autocomplete and type checking for boto3 Step Functions calls in VSCode with Pylance or PyCharm.
- Catch Step Functions API misuse at static analysis time using mypy or pyright before runtime.
- Generate paginator type hints for Step Functions list operations like ListStateMachines and ListExecutions.
- Provide explicit SFNClient type annotations for better code documentation and IDE support in large projects.
