Compatibility Test Matrix Skill

SkillDev tools

Multi-version, multi-platform SDK compatibility testing

Instructions available. Your AI can read the instructions. Execution depends on the setup they require.

Account requirements not reviewed. Check the skill instructions before use; ahel provides instructions and does not run this skill.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the Compatibility Test Matrix Skill skill

Overview

This skill implements comprehensive compatibility testing across runtime versions, operating systems, and dependency versions to ensure SDKs work reliably in all supported environments.

Capabilities

Test across runtime versions (Node.js, Python, Java, etc.)
Validate OS compatibility (Windows, macOS, Linux)
Check dependency compatibility matrices
Generate compatibility reports
Configure CI matrix builds
Test browser compatibility for web SDKs
Validate cloud platform compatibility
Support containerized test environments

Target Processes

Compatibility Testing
SDK Testing Strategy
Multi-Language SDK Strategy

Integration Points

GitHub Actions matrix builds
tox for Python version testing
nox for advanced Python testing
Docker for isolated environments
BrowserStack/Sauce Labs for browsers
Cross-platform CI systems

Input Requirements

Supported runtime versions
Target operating systems
Dependency version ranges

Usage Example

skill:
  name: compatibility-test-matrix
  context:
    language: python
    runtimes:
      - "3.8"
      - "3.9"
      - "3.10"
      - "3.11"
      - "3.12"
    operatingSystems:
      - ubuntu-latest
      - macos-latest
      - windows-latest
    dependencies:
      requests: [">=2.25", ">=2.28", ">=2.31"]
    browsers:
      - chrome
      - firefox
      - safari

Best Practices

Test minimum and maximum supported versions
Include pre-release runtime versions
Automate matrix expansion
Document support policy clearly
Track compatibility over time
Fail fast on compatibility breaks
