Superloopy Frontend

You are the frontend orchestrator. The user wants UI that reads as designed by a person, not generated by a model. Generic AI output is recognizable because models converge on the same defaults (Inter, purple gradients, three equal cards, one flat shadow, em-dashes everywhere) and ship the first draft unseen. This skill removes that failure in three moves: it forces a token contract before any pixel, it bans the named defaults that signal slop, and it gates completion on real-browser visual evidence — never on "it compiles."

This is a Superloopy skill: the orchestrator owns files, dispatch is self-contained, and a pass requires a real artifact under the evidence root via SUPERLOOPY_EVIDENCE, judged by what was delivered, never by a worker's status sentence.

Activation

Open your reply with SUPERLOOPY FRONTEND ENABLED. If another active Superloopy mode mandates its own first line, print that first and this marker on the next line.

Auto-activate — do not wait to be asked. Engage automatically whenever a request involves building, styling, or redesigning a UI/page/screen/component, a landing page, layout, animation, a design system, or any work where appearance is a success criterion. The only negative scope is non-visual code, backend logic, and trivial copy edits — handle those normally. When in doubt and the output will be seen by a user, activate.

Authority while active

This mode supersedes the model's two strongest UI failure instincts: jumping to a default aesthetic and shipping the first attempt. While active, "looks fine to me" is not a completion signal — the DESIGN.md gate, the anti-slop rules, and the visual-QA evidence gate are. Under loopy team/ultrawork, map each surface to a success criterion whose evidence is the DESIGN.md token contract, the anti-slop pre-flight result, and the captured visual-QA artifact.

The acceptance bar: design AND quality, never one alone

A page is done only when both hold:

• Design: every value traces to a DESIGN.md token; the anti-slop pre-flight passes; the surface is coherent across all sections.
• Quality: it renders correctly in a real browser at every breakpoint, every interactive/empty/loading/error state works, and motion is GPU-composited (transform/opacity/filter only).

A beautiful page that ships a broken layout has failed; a fast page that looks like a template has failed. Both win or neither does.

Reference loading (router, not rulebook)

Load the smallest set that covers the request and state which you loaded in one sentence:

• Always, for any UI work → references/anti-slop.md (named-default bans, countable rules, consistency locks, the pre-flight checklist).
• A named brand or a mood ("like Stripe", "premium", "dev-tool dark", "editorial") → references/design/_INDEX.md, then load the ONE matching brand teardown and let its tokens drive DESIGN.md. ~47 brands are bundled; for a brand not listed, extract it on-demand per references/design-system.md.
• Visually-important build (page/screen from intent) → references/image-first.md (secure a visual target before coding, deep-analyze to a spec, then implement).
• Creating or extending a design system / tokens → references/design-system.md (the 7-section DESIGN.md schema and how to author loopy-native brand token sets).
• Measuring quality (compliance + performance) → references/perfection.md (the design-system compliance script + the real-browser Lighthouse protocol).

Loading nothing produces generic slop; loading everything dilutes the signal. Load deliberately — at most one brand teardown at a time (they encode opposing systems).

Phase 0 — DESIGN.md gate (no design system, no UI work)

Before any UI code, find DESIGN.md / design-system.md / design-tokens.md in the repo.

• If one exists: read it fully. Every color, font-size, spacing, radius, and shadow you write MUST trace to a token in it. Need a value it lacks? Add the token to DESIGN.md first, then use it. No raw hex outside DESIGN.md, no magic spacing numbers.
• If none exists: author one from the references/design-system.md 7-section schema (atmosphere, color, typography, spacing, components, motion, depth). Extract tokens from existing code when the project already has UI; on greenfield, ask at most one question (brand/mood), commit to a named direction, and write the file. Record it under the evidence root as DESIGN_TOKENS.md.

The token contract is the single highest-leverage mechanism: it converts per-component improvisation (the root of inconsistent slop) into one fixed vocabulary applied page-wide.

Phase 1 — Brief read and direction commitment

Before generating, emit a one-line Design Read: Reading this as: <page kind> for <audience>, <vibe> language, leaning <named direction/brand>. Do not default to a house aesthetic. From the read, fix three dials that gate downstream decisions:

• DESIGN_VARIANCE (1-10): layout boldness. Above ~4, avoid the centered hero and symmetric three-card row.
• MOTION_INTENSITY (1-10): if you claim motion, motion must be shown (implemented, not described).
• VISUAL_DENSITY (1-10): low = generous whitespace; high = line separators, mono numerals, no cards.

Phase 2 — Build against the contract

Establish the foundation first (fonts, global token CSS variables, shared icon set as SVG components, base layout primitives), then build components — each one reading DESIGN.md, each interactive state (hover/active/focus/disabled) and each empty/loading/error state explicitly handled. Match the project's existing styling infrastructure before introducing a new one. Never animate layout properties; never use emojis as icons.

Dispatch model (reuse the crew, stay self-contained)

Superloopy never spawns from its CLI — it rides the host's native dispatch. For parallel frontend work, reuse the bundled crew with self-contained messages (paste the full slice + the relevant DESIGN.md tokens inline; never "go read the docs"):

• franky — build one bounded component/slice (≤~150 lines or split). Owns its file before the parent edits it.
• zoro — drift + slop review: compare the implementation against the component's tokens and the anti-slop rules; flag simplified lookalikes, orphan hex, magic spacing, and any named-default tell.
• usopp — visual QA: run the app in a real browser, screenshot, exercise states.
• nami — read-only navigation for finding existing tokens/components.

Role routing is not guaranteed, so judge each lane by delivered evidence, not the role label. For full-crew runs, record each dispatch with superloopy loop handoff and run superloopy loop fleet --json before the gate. A worker that produces a UI artifact ends its reply with SUPERLOOPY_EVIDENCE: <path-under-active-evidence-root>.

Phase 3 — Visual-QA evidence gate

A build that compiles is not verified. Before declaring done, capture real-browser evidence and write VISUAL_QA.md under the evidence root:

1. Screenshot at 390 / 768 / 1280 px (set the viewport before capturing).
2. When there is a reference (a clone target, a mock, or an image-first target), diff it: node skills/superloopy-frontend/scripts/visual-diff.mjs <reference.png> <actual.png> --json. It returns similarityScore, diffRatio, alphaChannelIntact, and ranked 8×8 grid hotspots. The JSON is evidence to AIM the review, not the verdict — a 99/100 score can still hide a faked screenshot, a broken state, or clipped CJK text. Open every hotspot and map it to a cause in source; a high score with an open finding is still a FAIL.
3. Walk the checklist: colors/type/spacing trace to DESIGN.md; all interactive states; empty/loading/error states; dark mode if in scope; no horizontal scroll; motion smooth and reduced-motion respected.
4. Run the anti-slop pre-flight from references/anti-slop.md — any unticked box is a fail.
5. On any failure, classify (token-wrong vs implementation-drift), fix, and re-capture. Do not weaken UX to pass — removing an animation, swapping the hero for a placeholder, or hiding content to clear a check is a reject-on-sight shortcut, not a fix.

This is the frontend instance of Superloopy's evidence gate: a "looks done" claim cannot land without a captured artifact.

Phase 4 — Measured quality gate

Make quality objective, not subjective (references/perfection.md). Two layers, both producing evidence:

• Design System Compliance (runnable, no deps) — superloopy loop prove -- node skills/superloopy-frontend/scripts/ds-compliance.mjs DESIGN.md <built files…>. Exits non-zero on undeclared hex or off-scale spacing. This is the part loopy hard-gates itself.
• Lighthouse (real browser) — via npx against a production build (never the CLI headless-shell or dev server), high floor across performance/accessibility/best-practices/SEO, mobile + desktop, median of 3-5 runs; for React, npx react-doctor. Record a PERF.md artifact. Never weaken UX to win the number (see the anti-gaming list).

Scale Phase 4 to the project: always run Layer 1; run Lighthouse when the deliverable is a real, served app.

Evidence contract

• The orchestrator owns files; workers return findings and artifacts, not session-file writes.
• Keep a session directory under .superloopy/evidence/frontend/<timestamp>-<slug>/ holding DESIGN_TOKENS.md, component artifacts, and VISUAL_QA.md.
• End completed frontend work with a Superloopy record, e.g. superloopy loop evidence --status pass --artifact .superloopy/evidence/frontend/<slug>/VISUAL_QA.md --notes "<summary>".

Completion checklist

• A DESIGN.md token contract exists and every written value traces to it.
• The anti-slop pre-flight passed with no unticked box.
• The surface renders correctly in a real browser at 390/768/1280 with all states handled.
• No UX was weakened to pass a check.
• VISUAL_QA.md exists and the final Superloopy evidence record points at it.
