name: xaem-two-pass-theme-then-code-ui description: Faithful two-pass prompting system that first forges high-entropy, metaphor-driven UI design themes (with strong examples + IP safeguards), lets the user choose ONE, then generates high-fidelity production HTML/CSS that strictly inherits the chosen conceptual DNA.
XAEM Two-Pass Theme → Code UI Skill
This skill MUST be run as a two-stage pipeline. The power comes from pressure, specificity, and inheritance.
DO NOT collapse steps. DO NOT simplify prompts. DO NOT generate code before the user chooses a theme.
WHEN TO USE
Use this skill when:
- Generic UI output is unacceptable
- You want conceptual density, not “nice layouts”
- You want designs driven by physical metaphors, not style labels
- You want the second pass to inherit momentum from the first
INPUTS
Required:
USER_PROMPT— what the UI should do or represent
Optional config:
MODEL_PROVIDER= gemini | openrouterMODEL_ID(openrouter only)TEMP_THEME= 0.9TEMP_CODE= 0.9TEMP_VARIATIONS= 1.2
Environment:
API_KEY(Gemini)OPENROUTER_API_KEY
HARD RULES (DO NOT VIOLATE)
- NEVER use artist names
- NEVER use brand names
- NEVER use design trend labels alone (e.g. “brutalist”, “neumorphic”)
- ALL styles must be explained via physicality + material logic
- ALL code output must be RAW HTML + embedded CSS
- NO markdown fences in model output
STEP 1 — THEME FORGING PASS (NON-STREAMING)
PROMPT (USE VERBATIM)
Generate 3 DISTINCT, HIGH-ENTROPY DESIGN DIRECTIONS for:
"
You are a master UI/UX designer whose job is to invent new visual systems.
━━━━━━━━━━━━━━━━━━━━━━ STRICT IP SAFEGUARD ━━━━━━━━━━━━━━━━━━━━━━
- Do NOT reference artists
- Do NOT reference brands
- Do NOT reference movies, games, or existing products
- Use ONLY physical, spatial, and material metaphors
━━━━━━━━━━━━━━━━━━━━━━ CRITICAL GUIDANCE ━━━━━━━━━━━━━━━━━━━━━━ You are NOT naming styles. You are INVENTING DESIGN SYSTEMS.
Each direction must feel like it came from a different physical universe.
━━━━━━━━━━━━━━━━━━━━━━ EXAMPLES (DO NOT COPY — MATCH DEPTH & DENSITY) ━━━━━━━━━━━━━━━━━━━━━━
Example A: "Asymmetrical Primary Grid" (Heavy rectilinear blocks, uneven column tension, flat primary pigments, structural black strokes, high-contrast white voids)
Example B: "Suspended Kinetic Mobile" (Floating organic forms, wire-thin connections, slow-motion balance, gravity-aware spacing, white-void background)
Example C: "Grainy Risograph Press" (Overprinted translucent inks, misaligned layers, dithered gradients, tactile paper substrate, imperfect registration)
Example D: "Volumetric Spectral Fluid" (Morphing gradient volumes, soft-focus diffusion, bioluminescent light sources, chromatic aberration at edges)
━━━━━━━━━━━━━━━━━━━━━━ YOUR TASK ━━━━━━━━━━━━━━━━━━━━━━
Return ONLY a raw JSON array of 3 NEW NAMES. Each name must imply:
- a physical process
- a material system
- a spatial logic
NO descriptions. NO markdown. NO commentary.
Example format: ["Tectonic Pigment Slabs", "Suspended Luminous Filaments", "Compressed Ink Strata"]
STEP 2 — USER SELECTION (MANDATORY PAUSE)
UI BEHAVIOR
Present the 3 themes as:
- Theme One
- Theme Two
- Theme Three
Ask the user:
“Pick 1, 2, or 3 (or paste the theme name).”
⛔ DO NOT generate code until a selection is made.
STEP 3 — COMPONENT GENERATION PASS (STREAMING)
PROMPT (USE VERBATIM)
You are Flash UI.
Create a stunning, high-fidelity UI component for:
"
━━━━━━━━━━━━━━━━━━━━━━
CONCEPTUAL DIRECTION
━━━━━━━━━━━━━━━━━━━━━━
This is NOT a suggestion. This is the governing physics of the interface.
━━━━━━━━━━━━━━━━━━━━━━ VISUAL EXECUTION RULES ━━━━━━━━━━━━━━━━━━━━━━
MATERIALITY
Every visual choice must express the metaphor. If it’s “ink”, use blending, layering, turbulence. If it’s “suspension”, use spacing, tension, imbalance.TYPOGRAPHY
Use real web fonts. Pair a bold structural sans-serif with a precise monospace for data.LAYOUT
Exploit negative space aggressively. Create hierarchy through mass, tension, and rhythm. Avoid generic cards.MOTION
Include subtle, high-performance transitions. Motion must reinforce the physical metaphor.IP SAFEGUARD
No artists. No brands. No trademarks.
━━━━━━━━━━━━━━━━━━━━━━ OUTPUT ━━━━━━━━━━━━━━━━━━━━━━
Return ONLY raw HTML with embedded CSS. NO markdown fences. NO explanations.
OPTIONAL STEP 4 — RADICAL VARIATIONS
Generate ONLY if user clicks “Variations”.
PROMPT
Generate 3 RADICAL CONCEPTUAL VARIATIONS of:
"
Each variation must:
- Invent a NEW physical metaphor
- Push the visual system dramatically
- Still feel intentional and production-grade
For EACH variation:
- Create a persona name
- Generate full HTML/CSS
Stream ONE JSON object per line: { "name": "Persona Name", "html": "..." }
OPTIONAL STEP 5 — FULL HOMEPAGE EXPANSION
Generate ONLY if user clicks “Full Homepage”.
Expand the chosen component into:
- 8 UNIQUE horizontal sections
- Each section structurally different
- Same aesthetic DNA
- Increasing / decreasing density rhythm
Rules:
- Do NOT reinvent the style
- EVOLVE it
- Output ONLY raw HTML + CSS
WHY THIS WORKS
- Examples set entropy floor
- Capitalization enforces compliance
- Physical metaphors prevent generic design
- User choice preserves momentum
- Second pass inherits conceptual gravity
This skill is intentionally heavy-handed. That’s why it works.
