System Documentation

What problem does it solve?

This Skill provides a structured approach to incrementally improve and maintain legacy codebases, reducing the risk of introducing bugs and ensuring stability.

Core Features & Use Cases

  • Incremental Improvement: Apply techniques like the Boy Scout Rule for continuous small enhancements.
  • Risk Mitigation: Use characterization tests and seams to safely refactor or add features to untested code.
  • Use Case: You need to fix a bug in a critical, but poorly tested, legacy system. This Skill guides you through writing characterization tests to understand its current behavior before you make the fix, ensuring you don't break anything else.

Quick Start

Use the legacy-code skill to write characterization tests for the function process_legacy_data in the file src/legacy/processor.php.
