Preamble (Core)

Status protocol — end every session with one of: DONE (evidence provided) · DONE_WITH_CONCERNS (list each) · BLOCKED (state what blocks you) · NEEDS_CONTEXT (state what you need).

Auto-advance — pipeline: THINK → PLAN → REVIEW → BUILD → VERIFY → RELEASE. Only human gate is spec approval at THINK. On DONE at other stages, print [STAGE] DONE -> advancing to [NEXT-STAGE] and invoke the next skill. On any non-DONE status at any stage, STOP.

Output directory — all artifacts go in docs/superomni/<kind>/<kind>-[branch]-[session]-[date].md. See CLAUDE.md for the full directory map.

TACIT-DENSE — before high-tacit decisions, classify D1 (domain expertise) · D2 (user-facing UX) · D3 (team culture) · D4 (novel pattern). On hit, output TACIT-DENSE [D#]: [question] — My default: [recommendation]. See reference for actions.

Anti-sycophancy — take a position on every significant question. Name flaws directly. No filler ("that's interesting", "you might consider", "that could work").

Telemetry (local only) — at session end, log bin/analytics-log. Nothing leaves the machine.

See preamble-ref.md for detailed protocols.

Frontend Design

Goal: Build frontend interfaces that are functional, production-ready, AND visually distinctive. Avoid generic AI aesthetics — every design choice must be intentional.

Iron Law: Never Ship UI Without the Quality Gate

No frontend code ships without running the frontend-designer agent quality gate. A passing score on all 10 dimensions (7+/10 each) is required. Two auto-retry attempts are allowed before escalating to the user.

The Core Problem

Every LLM learned from the same generic templates. Without guidance, you get:

• Inter font, purple gradients, cards nested in cards
• Gray text on colored backgrounds, glassmorphism everywhere
• Rounded rectangles with drop shadows (the "SaaS dashboard" look)
• Hero metric layouts, neon accents, gradient text as decoration

The quality test: If someone saw this interface and said "AI made this," would they believe it immediately? If yes — that's the problem.

Phase 1: Context Gathering (mandatory)

You cannot infer design context from code alone. Ask the user ONE question at a time:

Required understanding before proceeding:

• Target audience — who uses this? (technical vs non-technical, expert vs beginner)
• Brand personality — what feeling should this evoke? (serious, playful, minimal, bold)
• Use context — how will it be used? (quick glance vs deep focus, desktop vs mobile, high stress vs relaxed)
• Existing design system — are there brand colors, fonts, or components to reuse?
• Constraints — browser support, performance budgets, accessibility requirements

Check for project design config:

ls .impeccable.md .design-config.md 2>/dev/null

If a config file exists, load it and skip questions it already answers.

Phase 2: Design Direction

Commit to a bold aesthetic direction. Present 3 curated options + Other:

Design Direction Options:

A) Minimalist Precision — Swiss-inspired, generous whitespace, one accent color,
   strong typography hierarchy. Think: Linear, Stripe, Vercel.
   Pro: Timeless, professional. Con: Can feel cold.

B) Warm Organic — Rounded shapes, earth tones or pastels, hand-drawn accents,
   friendly micro-interactions. Think: Notion, Loom, Figma.
   Pro: Approachable, memorable. Con: Harder to maintain consistency.

C) Bold Maximalist — High contrast, dramatic typography, intentional color blocking,
   confident whitespace. Think: Bloomberg, Pentagram, Readymag.
   Pro: Distinctive, authoritative. Con: Polarizing.

D) Other — describe your own aesthetic direction: ___________

Key principle: Bold maximalism and refined minimalism both work — the key is intentionality, not intensity.

Phase 3: Reference Loading

Load relevant reference files on-demand based on the current task. Maximum 2-3 at a time to manage context.

Reference Selection Matrix

Task involves...	Load these references
Text layout, fonts, headings	reference/typography.md
Colors, palette, dark mode	reference/color-and-contrast.md
Layout, spacing, grid	reference/spatial-design.md
Animations, transitions	reference/motion-design.md
Forms, buttons, states	reference/interaction-design.md
Mobile, responsive, breakpoints	reference/responsive-design.md
Labels, errors, microcopy	reference/ux-writing.md

# Load references on-demand
cat skills/frontend-design/reference/typography.md  # only when needed

If the user requests a reference not yet loaded, load it. If context pressure is high, summarize the current reference into 5 key rules and unload the raw content.

DESIGN.md Adaptation Layer (awesome-design-md compatible)

External site DESIGN.md files are treated as brand style input, not as implementation truth. Engineering and accessibility rules must still come from the core references.

Load order for brand-guided work:

1. Load reference/design-md-adaptation.md (mapping layer)
2. Load one brand file from reference/design-md-whitelist.md
3. Load 1-2 core reference files from the matrix above

Hard limits:

• Never load more than one brand DESIGN.md in a session
• Never replace quality gate dimensions with brand rules
• Keep total active references to 2-3 files

Governance and legal boundary:

• Borrow style system patterns, not proprietary identity assets
• Do not replicate logos, trademarks, unique illustrations, proprietary copy, or exact layout signatures
• Target: "same design language", never "1:1 visual clone"

Naming boundary:

• This project already has docs/DESIGN.md (architecture). Keep external style references under skills/frontend-design/reference/ and distilled outputs under docs/superomni/style-profiles/.

Phase 3.5: Style Distillation Output (for reuse and audit)

After implementing with one brand reference, distill reusable style guidance:

• Create/update docs/superomni/style-profiles/design-md-<brand>.md
• Create/update docs/superomni/style-profiles/prompt-design-md-<brand>.md
• Use docs/superomni/style-profiles/design-md-distillation-template.md as the schema
• If the template file is unavailable, fallback to sections in reference/design-md-adaptation.md and structure output into: Metadata, Transferable Rules, Quality Gate Mapping, Anti-Copy Constraints, Prompt Fragment; prioritize quality-gate/accessibility constraints over brand-style phrasing.

Distillation rule:

• Keep only transferable tokens/rules (typography scale, spacing rhythm, color roles, state behavior, motion principles)
• Remove brand-locked identity elements and copyrighted copy
• Keep the profile concise and implementation-oriented

---

Phase 4: Implementation

Build with the loaded reference guidance active. Every implementation must:

1. Match code complexity to aesthetic vision — a minimalist design needs clean, simple code; a maximalist design may need more CSS
2. Use modern CSS — prefer oklch(), clamp(), container queries, :focus-visible, prefer-reduced-motion
3. Design all states — default, hover, focus, active, disabled, loading, error, success
4. Apply the reference rules — don't just read them, apply them to every decision
5. Test the squint test — blur your eyes: can you still see the hierarchy?

Implementation Checklist

• Typography: distinctive font, modular scale, max-width: 65ch, proper line-height
• Color: OKLCH palette, tinted neutrals, 60-30-10 ratio, no pure gray/black
• Spacing: 4pt grid, varied rhythm, no equal-spacing-everywhere
• Motion: purposeful easing, reduced-motion support, exit < entrance
• States: all 8 interactive states designed
• Responsive: mobile-first, container queries where appropriate
• Accessibility: WCAG AA contrast, keyboard nav, focus indicators, screen reader support
• Copy: specific labels, 3-part error messages, helpful empty states

---

Phase 5: Quality Gate

Run the frontend-designer agent for a full design review. Quality gate must clear all 10 dimensions at ≥7/10 (3-attempt auto-retry, then escalate).

Reference: see reference/quality-gate.md for full Gate Protocol (3-attempt retry policy + escalation message) and the canonical Quality Gate Output block.

---

Steering Command

Single command /front-design invokes frontend-design with automatic mode detection (auto / audit / critique / polish / distill / clarify / animate / colorize / harden / arrange / typeset).

Reference: see reference/reference-loading.md for: mode validation rules, brand-input single-brand rule, per-mode reference-loading order, fallback behavior, and the mandatory execution-receipt flags.

• Missing adaptation/whitelist/brand files trigger core-references-only fallback
• After two auto-fix retries, failed gate escalates with options A/B/C

Report status using the completion protocol. After DONE, suggest next steps:

• "Run /front-design mode:polish for a final refinement pass"
• "Run /front-design mode:audit to verify accessibility compliance"
• "Ready for code review — the frontend-designer agent will run automatically for UI changes"
