Use when the user is about to paste or serialize a large JSON array into a prompt, has a payload with ≥5 uniform objects, or is optimizing an LLM pipeline for cost/context. Knows the format shapes (tabular `[N]{a,b}:` rows, inline `[N]: ...`, expanded), when TOON helps vs hurts, and how to invoke installed TOON commands or wrappers when available. Example queries — "convert this API response to TOON", "will this JSON benefit from TOON", "how does TOON handle nested objects".

Use when the user asks to compare task flows, count interaction cost, reduce clicks or keystrokes, evaluate command/menu/navigation choices, model expert performance, or redesign a workflow using GOMS, KLM, CMN-GOMS, or cognitive walkthrough style reasoning.
