rseng-legacy-code

Covers working safely with inherited research code: characterization tests before any change, incremental modernization of untested scripts, recovering intent from code without documentation, and deciding between refactor, rewrite and retire. Use PROACTIVELY when asked to change code that has no tests, and when the user inherits a codebase from a departed researcher, mentions legacy or untested code they are afraid to touch, or wants to change code that has no tests. (Migrating off commercial platforms like MATLAB, IDL or SAS to open alternatives is rseng-open-source-migration; this skill supplies the characterization-test safety net it builds on.)
