Type annotations for boto3 FIS 1.43.0 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes, if you use boto3 FIS in a Python project and want IDE autocomplete and static type checking. Install friction is minimal, maintenance is active, the license is permissive, and there are no known vulnerabilities. Consider boto3-stubs-lite as an alternative if you experience PyCharm performance issues with the full stub set.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; best used alongside a type checker like mypy or pyright, or an IDE with type-aware language server support.
- Low install friction with a single lightweight runtime dependency (typing-extensions).
- Actively maintained as of 2026-06-22 with stable production status.

What it is and what it does
This package is a type stub library for boto3's FIS (Fault Injection Simulator) service, generated automatically from boto3 1.43.0 using mypy-boto3-builder 8.12.0. It provides complete type annotations for FIS client operations, paginators, and type definitions, enabling static type checking and IDE autocomplete in VSCode, PyCharm, Emacs, Sublime Text, and other editors that support mypy or pyright.
When installed, it allows developers to write boto3 FIS code with full type safety—the IDE and type checker can catch errors at development time rather than runtime. It works transparently with boto3 without requiring explicit type annotations in most cases, though it can be used with TYPE_CHECKING guards to keep it out of production dependencies if needed.
Use it for
- Enable IDE autocomplete and type checking for boto3 FIS API calls in VSCode with Pylance or PyCharm.
- Catch type errors in FIS client usage before runtime using mypy or pyright in CI/CD pipelines.
- Generate type-safe paginators for FIS list operations (list_actions, list_experiments, etc.).
- Document FIS API contracts in code through explicit type annotations for client, paginator, and response types.
- Use in a TYPE_CHECKING block to get development-time type hints without adding a runtime dependency.
