SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This skill helps developers identify breaking changes and incompatibilities between different versions of Python libraries, ensuring smoother upgrades and preventing runtime errors.

Core Features & Use Cases

  • API Comparison: Compares function signatures, class definitions, parameters, and return types between two library versions.
  • Breaking Change Detection: Identifies removed functions, classes, methods, and incompatible parameter modifications.
  • Use Case: Before upgrading a critical Python dependency in your project, run this skill to automatically detect any API changes that could break your existing codebase.

Quick Start

Use the python-api-consistency-validator skill to compare the old and new versions of a Python library located in the 'old_lib/' and 'new_lib/' directories.

Frequently Asked Questions about python-api-consistency-validator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I detect breaking API changes when upgrading a Python library?▼

Detect breaking API changes by running static analysis to compare function signatures, class definitions, and exceptions across library versions. This skill identifies incompatible parameter modifications and removed methods to guide safe upgrades.

What is the best way to compare Python library signatures for backward compatibility?▼

Comparing Python library signatures for backward compatibility involves analyzing parameter types and return types between two directories. This skill generates a detailed JSON report highlighting incompatible modifications and removed functions.

How do I check Python API compatibility before migrating dependencies?▼

Check Python API compatibility before migrating by placing old and new library versions in separate directories. The skill validates behavior and exceptions, identifying incompatible modifications to prevent runtime errors during migration.

Can I use static code analysis to find removed methods in Python library updates?▼

Yes, static code analysis can find removed methods in Python library updates. This skill compares class definitions and function signatures between versions to locate removed functions and incompatible parameter modifications.

What limitations exist when validating API consistency across Python versions?▼

Validating API consistency across Python versions is limited to static analysis of code in local directories. It detects signature and class definition changes but requires placing old and new library versions in specific folders.
