Turn a code-owner correction (or a recurring mistake) into a durable rule - the right conventions-doc edit, and a real failing lint guard whenever the rule is mechanically checkable. This is the self-improving loop the factory leans on - when something goes rogue, capture it so the linter/conventions-doc catches it next time instead of a human re-explaining it. Also runs as a weekly sweep over recent merged work. Use when asked to "/add-rule", "turn this into a rule", "make sure this never happens again", "capture this correction", "add a lint guard for X", or "do the weekly rule review".

Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch.
