What problem does it solve? Test analysis skills need framework-specific lookup tables (assertion APIs, skip annotations, sleep patterns, tag syntax) that vary across languages, and this Skill centralizes those per-language reference files so analysis stays language-neutral. ## Core Features & Use Cases - Extension Discovery: Lists available per-language extension files covering .NET, Python, TypeScript, Java, Go, Ruby, Rust, Swift, Kotlin, PowerShell, and C++. - Capability Tagging: Each extension declares per-capability support such as tag support levels (auto-edit, report-only, convention-based) so skills can gate behavior safely. - Use Case: When the test-quality-auditor agent analyzes a pytest codebase, it calls this Skill to locate extensions/python.md, then reads it to learn pytest fixtures, markers, and skip conventions before auditing assertion quality. ## Quick Start Ask the agent to find the test analysis extension file for your project's language and test framework before running a test quality audit.
