Mode-aware writing critic. Distilled from Rachel Konrad's Stanford GSB "Winning Writing" course (spring 2026), the 10 rules of cold outreach, Heidi Roizen's mailing rules, and live class critiques. Loads a rule catalog (rules/catalog.json) and a mode definition (rules/modes.json) at invocation. Use whenever drafting or critiquing a cold email, outreach message, LinkedIn intro, exec memo, personal essay, bio, README, or LinkedIn post. Pass a mode argument to filter which rules apply.
