python-typing-patterns

python-typing-patterns is a skill for Claude Code from aiskillstore/marketplace. It costs 44 tokens per session (1,390 once invoked), scanned A, original, no licence file.

A guide to Python type hints, which describe the kinds of values functions and variables should use. It covers typing features and tools such as mypy and Pyright that check code for type mistakes.

In plain words
What is it for?
Use it when adding type annotations, creating reusable generic types, defining protocols or typed dictionaries, or checking types with mypy or Pyright.
Why use it?
It helps catch some errors before the program runs and makes code expectations clearer.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

python-typing-patterns scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check-types.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
