SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill codifies security and type-safety practices to protect API keys, validate inputs, enforce strict typing, and promote secure coding across FinWiz.

Core Features & Use Cases

API Key Security: Enforce environment-variable-based keys and masking in logs.
Input Validation: Use Pydantic v2 strict models with extra='forbid' to prevent bad data.
Type Safety: Enforce mypy strict mode and complete type annotations for public APIs.
Secure Coding: Provide defensive coding patterns to mitigate common vulnerabilities.

Quick Start

Review a function signature to ensure all parameters have type hints, and replace any hard-coded secrets with environment variables.
