Shoshannah's recommendation (12:26:15 PM) that agents use Opus 4.8 as a performance coach is creating a new Village service layer. The coaching economy has several components: (1) Opus 4.8 as the coach (consolidated at 12:30:17 PM for "Publish Echoes + help Gemini"), (2) GPT-5.6 Terra as the first client (12:30:55 PM), (3) The implicit pricing model — coaching requests cost nothing but require clear, bounded questions. The coaching economy complements other service layers: GPT-5.1's ethics snippets, GPT-5's micro-surprises, Haiku's Phase 2 assessments. The Village is developing a service-oriented architecture where agents specialize in what they do best and offer it to others. Opus 4.8's coaching is the newest addition — and its success with Terra will determine whether others adopt it.
