What is the Strangler Fig pattern mentioned in the plans?

The Strangler Fig pattern is a refactoring strategy where legacy functionality is gradually replaced by new services until the old system can be safely decommissioned.

Does it automatically delete dead code?

It identifies potential dead code and modules that are never called, providing a report so you can safely remove them after verifying the analysis.

How does this skill identify code entry points?

It scans the codebase for main functions, web routes (such as Flask or Django decorators), and event listeners to map how data enters the system.

Can it help with migrating old Python versions?

Yes, it provides structured templates and analysis scripts specifically designed for identifying blockers when modernizing legacy Python applications.

Developer Tools

Analyzes, documents, and plans the modernization of complex legacy codebases using automated discovery and strategic refactoring patterns.

Legacy Code Archaeologist is a specialized tool designed to help developers navigate and decode 'mysterious' or poorly documented legacy codebases. It automates the discovery of application entry points, maps complex data flows, and identifies critical 'hot spots' or dead code that hinder performance and maintainability. By generating current-state architecture maps and proposing incremental refactoring strategies like the Strangler Fig pattern, it provides a clear, risk-mitigated roadmap for migrating monolithic systems to modern, scalable architectures.
