What is the difference between Verification and Validation in this skill?

Verification (VER) focuses on whether the product meets technical specifications (built correctly) through tests and reviews, while Validation (VAL) ensures it meets actual user needs (built the right thing) through stakeholder approval.

How does this skill handle ineffective code reviews?

It identifies 'Rubber Stamp' reviews as an anti-pattern and provides a checklist-based approach along with social dynamics playbooks to ensure reviews are thorough and accountable.

What are the test coverage requirements for CMMI Level 3?

Level 3 projects require at least 70% test coverage for critical paths, mandatory automated testing in CI pipelines, and documented test strategies.

When is it acceptable to ship code without tests?

Shipping without tests is only allowed during production outages via the TEST-HOTFIX protocol, which requires documented justification and mandatory retrospective tests within 48 hours.

Does this skill provide code for specific testing frameworks?

No, this skill focuses on the engineering process and strategy. For framework-specific implementation like PyTest or Jest, you should use domain-specific engineering skills.

Quality Assurance & SDLC Engineering

关于

This skill provides a structured framework for Quality Assurance within the software development life cycle, specifically focusing on the critical distinction between Verification ("Did we build the product right?") and Validation ("Did we build the right product?"). It guides developers through CMMI-based quality levels, establishing mandatory test coverage, peer review standards, and user acceptance testing (UAT) protocols. By integrating this skill, Claude helps teams move beyond basic unit testing toward a mature QA strategy that prevents "test-last" anti-patterns and ensures high-quality releases through data-driven defect management and stakeholder validation.
