Use when building, extending, reviewing, or planning any part of the Bandwise monorepo, a multi-tenant SaaS kit around TypeSafe's System One models (Jev first, then future models). Covers the console (Next.js, Drizzle, Postgres RLS, Better Auth, Stripe), the core run engine and confidence router, question set specs and versions, the model registry and model upgrades, headless management (management API, operation registry, @bandwise/cli, MCP server, agent tokens, approvals), app onboarding and deploy (opportunities, typed codegen, deploy targets, app bindings, specs as code), the effectiveness loop (app feedback, labeling, quality targets, threshold tuning, champion/challenger, set health), the savings ledger and admin reports, the Definition Studio, the embed kit (@bandwise/client, @bandwise/react), plugins, and the Chrome extension. Also use whenever code calls Jev or System One (noul, choice, score, confidence bands, state). Defers raw Jev API details to the official typesafe skill and docs.typesafe.ai.

Bandwise is a multi-tenant SaaS that wraps TypeSafe's System One models, Jev first and by default, in a managed product. Orgs set up apps, define goals, build versioned question sets, tune confidence bands, publish them live, and call them from any app by ID or through generated typed code. Every run reports what it cost and what it saved against an LLM.
