Why does Tester Detective forbid using grep or find?

Tester Detective relies on Abstract Syntax Tree (AST) analysis through claudemem. This provides a structurally accurate map of code relationships (callers) that text-based search tools like grep cannot reliably identify.

Can I use Tester Detective to find test utilities?

Yes, it includes specialized mapping commands to find test configurations, mocks, stubs, fixtures, and helper utilities across the entire project.

How does this skill identify untested code?

It analyzes the 'callers' of a function. If no callers originate from files with test naming patterns (like *.test.ts or *.spec.ts), the function is flagged as having a coverage gap.

Which programming languages does this skill support?

It supports any language compatible with claudemem's indexing, including TypeScript, JavaScript, Python, Go, Rust, and more.

What is required to use the automated test-gaps feature?

Automated gap detection requires claudemem v0.4.0 or higher. This version enables the skill to automatically rank and list untested symbols based on their importance to the codebase.

セキュリティとテスト

Investigates test coverage and quality using AST-based callers analysis to identify untested code and critical gaps.

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.
