SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Undocumented legacy codebases are difficult to understand, hindering migration, maintenance, and feature delivery.

Core Features & Use Cases

  • Architecture discovery and component cataloging for legacy repos with little or no documentation.
  • Dependency analysis and data-flow tracing to map critical interactions and plan safe migrations.
  • Use Case: teams inheriting a monolith with sparse docs can generate an actionable migration roadmap and artifact inventory.

Quick Start

Run the reverse-engineering workflow on a new repo to produce an architecture and migration plan.

FAQPage Schema
How do I analyze an undocumented legacy codebase to understand its architecture?▼

Analyzing undocumented legacy codebases involves identifying architecture, mapping dependencies, and extracting business logic to generate a comprehensive artifact catalog. This process decodes monolithic structures into clear documentation for maintenance.

What is the best way to trace data flow and extract business logic from a monolith?▼

The best approach to trace data flow and extract business logic from a monolith is through a six-phase process including structure analysis, component cataloging, dependency graphing, and data-flow tracing to map critical interactions.

How do I generate a migration roadmap for a multi-language repo with sparse documentation?▼

Generating a migration roadmap for a multi-language repo requires completing architecture discovery, component cataloging, and dependency graphing first. The resulting artifact inventory maps critical interactions to plan safe migrations.

Can I use dependency graphing to plan safe migrations for inherited monolithic code?▼

Yes, dependency graphing maps critical interactions within inherited monolithic code to plan safe migrations. Visualizing component relationships ensures migration roadmaps account for structural constraints and data-flow dependencies.

What are the limitations of reverse engineering legacy code with minimal documentation?▼

Reverse engineering legacy code with minimal documentation is limited by the accuracy of inferred data-flow tracing and business-logic extraction. Migration roadmaps depend heavily on the structural clarity of the existing monolithic architecture.
