How to recover documentation from existing code

What to do when code exists but documentation and diagrams do not. Reverse engineering can recover artifacts and keep them current.

A common situation: the project works, but documentation is missing and only the author knows the structure. New people spend days understanding the code.

What reverse flow means

Normal artifacts go forward: idea to requirements to code. Reengineering goes backward: code to artifacts. It recovers modules, objects, APIs, links and draft docs.

  • Module map and dependencies
  • Recovered entities and fields
  • API endpoints and contracts
  • Draft documentation by module

Why it matters

Reengineering turns a black box into a map. The team can onboard people, plan changes and reduce risk.

Closed loop

After reverse engineering, code and artifacts are connected. Code changes update artifacts, and artifact changes show their impact on code.

Key idea

AI SDLC works backward too: it recovers current artifacts and documentation from existing code.
