What are the prerequisites for running a deep dive?

You need a project root with an analysis_progress.json and a DEEP_DIVE_PLAN.md file to track the multi-phase analysis workflow.

How does this differ from standard documentation generators like JSDoc or Sphinx?

Unlike standard tools that only extract syntax, this skill uses Claude's semantic understanding to explain the 'Why' behind design decisions and identifies complex architectural patterns that scripts alone miss.

Is the documentation generated by this skill reliable?

Yes. The skill operates under an 'Absolute Source of Truth' principle, which forbids making claims that cannot be irrefutably verified by reading the actual source code during the analysis phase.

Can I use this for security audits?

It is highly effective for identifying security 'red flags' like hardcoded secrets or missing validations, though it is designed to skip reading sensitive files like .env or .pem files for safety.

Learning & Documentation

Performs systematic codebase analysis to generate high-fidelity documentation covering architectural patterns, data flows, and design intent.

Deep Dive Analysis is a comprehensive Claude Code skill designed to bridge the gap between raw source code and deep architectural understanding. By combining mechanical AST extraction with AI-driven semantic reasoning, it produces documentation that explains not just what the code does, but why it exists, how it integrates, and the consequences of future changes. Following a rigorous 'Absolute Source of Truth' principle, it ensures all generated documentation is verified against actual source code, making it an essential tool for onboarding to new projects, preparing for major refactorings, or repairing stale documentation ecosystems.
