Agent request

Review the Skillstore skill "python-typing-patterns" from https://skillstore.io/skills/0xdarkmatter-python-typing-patterns.md and its manifest at https://skillstore.io/api/skills/0xdarkmatter-python-typing-patterns/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "python-typing-patterns". A function accepts either text or bytes and should return the same kind of value.

Expected outcome:

The skill would recommend overload signatures for each input type, followed by one implementation that handles all accepted cases.

Using "python-typing-patterns". A project wants stricter type checking but has untyped tests and third-party packages.

Expected outcome:

The skill would suggest strict defaults, targeted test overrides, missing-import settings, and separate mypy or pyright configuration examples.

Using "python-typing-patterns". A service needs validation for request dictionaries at runtime.

Expected outcome:

The skill would suggest TypedDict for static shape and Pydantic TypeAdapter or BaseModel patterns for runtime validation.

All static findings were adjudicated as false positives after reviewing the referenced files. The skill contains Python typing documentation, sample configuration, and a local type-checking helper script; no prompt injection, credential theft, data exfiltration, or malicious system behavior was found.

What You Can Build

Annotate new Python services

Use the reference patterns to add clear function signatures, collection types, and strict checker settings before code grows complex.

Modernize legacy type hints

Apply unions, TypedDict, Protocol, and TypeGuard patterns to make existing Python code easier to check and maintain.

Teach practical Python typing

Use the examples as structured explanations for teams learning mypy, pyright, generics, overloads, and runtime validation.

Try These Prompts

Add basic annotations

Add Python type hints to this module using modern Python 3.10+ syntax. Keep the changes simple and explain any uncertain types.

Choose safer collection types

Review these function signatures and suggest better collection types, such as Sequence, Mapping, Iterable, TypedDict, or Protocol.

Configure strict type checking

Create a practical mypy and pyright configuration for this Python project. Explain which strict settings should be enabled first.

Design advanced typed APIs

Use TypeVar, ParamSpec, Protocol, overload, and runtime validation where appropriate to make this API type-safe without overcomplicating it.

Best Practices

Start with function boundaries, public models, and configuration before annotating every internal variable.
Use Protocol for behavior-based interfaces and TypedDict for dictionaries with known keys.
Run mypy or pyright regularly so type annotations stay accurate as code changes.

Avoid

Do not use Any to silence errors unless the value truly has an unknown type boundary.
Do not add overloads when a simple union or generic type explains the API clearly.
Do not rely on runtime validation alone when static type checks can catch issues earlier.
