Generate a "DNA profile" of a codebase's coding style (naming conventions, formatting, comment voice, structural habits, error-handling philosophy, and idioms), then use it so new or AI-written code is indistinguishable from the existing author's code. Use this skill whenever the user wants to match a codebase's existing style, make AI contributions "blend in", "mimic" or "fingerprint" a coding style, capture house conventions, build a style guide from existing code, onboard to an unfamiliar repo's conventions, or check whether code "looks AI-generated" / has tells. Triggers on phrases like "match my coding style", "make it look like I wrote it", "codedna", "capture the conventions", "style guide from the code", "why does this read as AI-generated", "genetic map of the code", "mimic the codebase", and on any request to contribute significant code to an existing repo where matching house style matters.
