Tester Detective

About

Tester Detective is a high-precision QA auditing skill designed for deep technical investigation of test suites. By leveraging Abstract Syntax Tree (AST) analysis via claudemem v0.3.0+, it moves beyond superficial text searches to map the structural relationships between production code and test files. It identifies exactly which tests call specific functions, detects coverage gaps in high-importance code using PageRank, and audits test quality for edge case handling. This skill is essential for developers and QA engineers who need an accurate, data-driven report on code health and testing deficiencies in complex codebases.

Key Features

• Structural verification of edge case and error path coverage
• Mapping of test infrastructure, configs, and mocks
• AST-based test discovery using callers analysis
• 0 GitHub stars
• Prioritized reporting based on code symbol importance (PageRank)
• Automated detection of high-priority coverage gaps

Use Cases

• Verifying that new feature implementations include adequate edge case tests
• Auditing legacy repositories to identify critical business logic lacking test coverage
• Mapping complex test utilities and infrastructure in large-scale monorepos
