What problem does it solve? Development teams often lack visibility into which test scenarios are missing, whether coverage thresholds are met, and whether existing tests are flaky, slow, or poorly structured. This Skill performs autonomous black box analysis to identify untested code paths, security gaps, and quality issues before they cause production failures. ## Core Features & Use Cases - Black Box Coverage Analysis: Identifies all possible inputs and expected outputs for every function or endpoint, then maps existing tests to find untested scenarios prioritized by risk (CRITICAL to LOW). - Quality & Security Assessment: Detects flaky tests, slow tests, disabled tests, weak assertions, and missing security tests for authentication, injection, IDOR, and data protection. - Business Mapping & CI/CD Review: Maps tests to user stories and acceptance criteria, validates coverage thresholds (80% global, 100% business rules), and analyzes pipeline test integration. - Use Case: Before a release, ask the Skill to review your repository. It runs coverage tools, finds that duplicate-email registration is untested (CRITICAL), flags three time-dependent flaky tests, and delivers a prioritized report with concrete test code examples. ## Quick Start Ask the assistant to analyze the test coverage and quality of this repository and list the missing tests by priority.
