Does it handle sensitive information like API keys?

No, the skill is explicitly programmed to never output secret values or credentials found in environment variables or config files; it only lists variable names and their purpose.

What formats does the reverse engineer skill output?

It generates Markdown specifications (SPEC-XXX.md), Gherkin feature files (.feature) for BDD, and integrated System Archeology Reports combining all analysis dimensions.

Can it analyze database structures?

Yes, the 'data' subcommand scans schemas, ORM models, and migration files to build entity-relationship models and data flow maps even without a live database connection.

How does the skill prevent AI hallucinations?

The skill follows strict anti-hallucination rules, using mandatory certainty tags ([Confirmed], [Inferred], [Unknown]) and requiring a file/line source reference for every finding it reports.

What is 'system archeology' in the context of this skill?

It is a framework for discovering the underlying structure of a codebase by analyzing its logic (code), data (schemas), and runtime (configs) dimensions to create a complete picture of how a system works.

Analyzes legacy codebases across logic, data, and runtime dimensions to generate comprehensive system specifications and documentation.

This skill provides a structured framework for 'system archeology,' allowing developers to deeply understand existing software projects without manual documentation. By scanning source code, database schemas, and runtime configurations, it reconstructs logic flows, entity-relationship models, and infrastructure baselines. It incorporates strict anti-hallucination rules, ensuring every finding is tagged with certainty levels and mapped back to specific source code lines, making it an essential tool for onboarding to legacy projects, refactoring complex systems, or performing security audits.
