Workflow smells are structural problems that do not crash your system — they just make it fragile, slow, or wrong in ways you discover too late.\n\nPaste any workflow description — automation, agent pipeline, n8n flow, Claude tool chain — and this automation returns exactly 3 red flags. Not a 20-item checklist. Not a redesign recommendation. Three specific smells, ranked by the damage they cause.\n\nBuilt for: Claude Code builders, automation architects, AI engineers before they push to production.
