codebase-replication
Learn advanced coding rules, syntax idioms, design patterns, file management, and tooling conventions from a source repository and apply them to the user's repository as a reusable rules file plus reusable knowledge pack. Use this whenever the user says learn from this repo, copy style from, apply patterns from GitHub, modernize my code like X, replicate codebase, or gives a source repo path/URL plus a target repo. Always use for repo-to-repo style transfer even if they don't say skill.
