Agent Skills: prose-correction

Rewrite technical prose into its artifact's register and strict linear causality, then strip AI diction. Audits inline comments, docstrings, commit messages, PR titles and bodies, documentation, chat responses, or any draft text; with no target named, it audits the current change set. Use before opening a PR, during a completion check, or when the user says "prose correct this", "fix this writing", "remove the AI tells", or "make this linear".
