What is the main purpose of the reverse-engineer skill?

It analyzes source code to generate structured specifications, BDD scenarios, and test coverage reports, helping developers understand and document existing logic.

How does it prevent AI hallucinations?

It uses strict labeling for every finding (Confirmed, Inferred, or Unknown) and requires direct source-line citations for every generated requirement.

What does the /reverse tdd command do?

It takes a Gherkin .feature file, searches your repository for matching tests, and outputs a coverage matrix showing which scenarios are covered or missing.

Can it generate test files from my code?

It focuses on generating BDD Gherkin scenarios and mapping them to existing tests to report on coverage gaps rather than writing unit tests from scratch.

Is this skill only available in Chinese?

This version (locales-zh-CN) provides Chinese instructions and output, but the logic is applicable to any codebase regardless of the programming language.

安全与测试

Transforms existing source code into structured technical specifications, BDD scenarios, and TDD coverage reports with full traceability.

The Reverse Engineering Assistant is a specialized tool designed to bridge the gap between legacy code and formal documentation. It automates the extraction of software specifications (SDD) from raw source code, converts acceptance criteria into Gherkin-formatted BDD scenarios, and audits test coverage by mapping features to existing test files. By employing a strict anti-hallucination framework—classifying findings as Confirmed, Inferred, or Unknown and providing direct source-line references—it ensures that generated documentation is grounded in reality, making it indispensable for system modernization and maintaining high-quality testing standards.
