Escalatory browser verification - open the app in a real browser and test it. Two modes - builder-verify (test the feature you just built) and cold-review (fresh-eyes reviewer pass over a whole surface or site). Use after "READY FOR REVIEW", before shipping a preview/demo to a human, or when asked to "actually test this" / "review this like a stranger".
Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface. Covers websites, landing pages, dashboards, product UI, app shells, components, forms, settings, onboarding, and empty states. Handles UX review, visual hierarchy, information architecture, cognitive load, accessibility, performance, responsive behavior, theming, anti-patterns, typography, fonts, spacing, layout, alignment, color, motion, micro-interactions, UX copy, error states, edge cases, i18n, and reusable design systems or tokens. Also use for bland designs that need to become bolder or more delightful, loud designs that should become quieter, live browser iteration on UI elements, or ambitious visual effects that should feel technically extraordinary. Not for backend-only or non-UI tasks.
Scan an entire SvelteKit project's routes and generate a full design-makeover epic — a dependency-wired task tree that runs the impeccable treatment (critique → audit → findings-driven fixes → polish → re-critique) against every high-value route, gated behind a shared design-system foundation phase. Also supports append mode: when a feature batch adds new routes after the epic is already running, use the Append mode section to add cluster tasks to the existing epic (foundation already done — no F1/F2/F3 needed). Use when the user wants to redesign/overhaul the whole app's UI, give all routes the impeccable treatment, plan a design firm's work across the app, or add new-route tasks to an existing makeover epic. Pairs with the impeccable skill and jat:tasktree.
Complete current JAT task with full verification. Verifies work (tests/lint), commits changes, writes memory entry, closes task, and emits final signal. Session ends after completion.
Onboard a new client project — analyze client docs, create knowledge bases, write Supabase migration, generate PRD and tasktree. Run after jst-new has set up the mechanical scaffolding.
Begin working on a JAT task. Registers agent identity, selects a task, searches memory, detects conflicts, declares files, emits IDE signals, and starts work. Use this at the beginning of every JAT session.
