What it does

Synthwave is an agent skill from sickn33/agentic-awesome-skills. Web and App implementation guide for Synthwave. Trigger when user wants 80s-inspired neon, dark backgrounds, outrun grids, and Miami Vice aesthetics.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Cross-platform mobile apps. It works with React Native. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

  • User wants 80s-inspired neon
  • Dark backgrounds
  • Miami Vice aesthetics

Example prompts

  • “/synthwave”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Dark Mode by Default: Absolute pitch-black or deep purple backgrounds.
  2. Neon Glowing Vectors: Bright magenta, cyan, and yellow wireframes, text, and grids. Heavy use of box-shadow and text-shadow for glow…
  3. The Perspective Grid: The defining visual is a glowing grid that fades into a vanishing point on the horizon.

What it can do on your machine

Read from SKILL.md and the folder at commit 1e53ce2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are css, swift, dart, javascript and kotlin).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Synthwave loads about 2.1k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 380 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~40
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Synthwave (Outrun)

"Driving a Ferrari through a neon-lit digital grid at midnight."

When to Use

Use this sub-style when the user's request matches the aesthetic described above. This is a child reference of the design-it skill and is not meant to be triggered directly.

Core Principles

  1. Dark Mode by Default: Absolute pitch-black or deep purple backgrounds.
  2. Neon Glowing Vectors: Bright magenta, cyan, and yellow wireframes, text, and grids. Heavy use of box-shadow and text-shadow for glow effects.
  3. The Perspective Grid: The defining visual is a glowing grid that fades into a vanishing point on the horizon.

Visual DNA

  • Colors: Deep space backgrounds (#0B0C10, #110022). Glowing neon accents: Cyan (#00FFFF), Hot Pink (#FF00FF), Electric Yellow (#FFFF00).
  • Typography: 80s chrome text, brush script (like a neon sign), and heavy italicized sans-serifs.
  • Shadows: Drop shadows are not black; they are the same color as the element, heavily blurred, to create light emission.

Web Implementation

  • Rely on text-shadow for neon signs and 3D transforms for the floor grid.
  • CSS Example:
css
body {
  background-color: #090014;
  color: #fff;
  font-family: 'Montserrat', sans-serif;
  overflow-x: hidden;
}

/* Neon Text Glow */
.synth-neon-text {
  font-family: 'Mr Dafoe', cursive; /* A classic 80s script */
  font-size: 4rem;
  color: #fff;
  text-shadow: 
    0 0 5px #fff,
    0 0 10px #fff,
    0 0 20px #FF00FF,
    0 0 40px #FF00FF,
    0 0 80px #FF00FF;
}

/* The Perspective Grid Floor */
.synth-grid {
  position: absolute;
  bottom: 0; left: -50%;
  width: 200%; height: 50vh;
  background-image: 
    linear-gradient(rgba(0, 255, 255, 0.8) 2px, transparent 2px),
    linear-gradient(90deg, rgba(0, 255, 255, 0.8) 2px, transparent 2px);
  background-size: 50px 50px;
  
  /* Create the 3D horizon effect */
  transform: perspective(500px) rotateX(60deg);
  transform-origin: top center;
  
  /* Fade out towards the horizon */
  mask-image: linear-gradient(to bottom, transparent 0%, black 100%);
  -webkit-mask-image: linear-gradient(to bottom, transparent 0%, black 100%);
}

App Implementation

SwiftUI
swift
struct NeonText: View {
    let text: String
    
    var body: some View {
        Text(text)
            .font(.custom("Mr Dafoe", size: 64))
            .foregroundColor(.white)
            // Layering shadows to create a glowing bloom
            .shadow(color: .white, radius: 2)
            .shadow(color: .pink, radius: 5)
            .shadow(color: .pink, radius: 10)
            .shadow(color: .pink, radius: 20)
    }
}

struct SynthwaveScreen: View {
    var body: some View {
        ZStack {
            Color(red: 0.03, green: 0.0, blue: 0.08).ignoresSafeArea() // #090014
            
            VStack {
                NeonText(text: "Outrun")
                Spacer()
            }
            
            // Note: A 3D perspective grid requires SceneKit or a pre-rendered image
            // Native SwiftUI 3D transforms apply to the view, but won't draw an infinite floor grid easily.
            Image("synth_grid")
                .resizable()
                .scaledToFill()
                .frame(height: 300)
                .offset(y: 200)
        }
    }
}
  • Stack multiple .shadow(color:radius:) modifiers directly on the text to create a vibrant neon bloom effect.
  • The 3D wireframe horizon grid is best achieved via a pre-rendered image background.
Flutter
dart
class NeonText extends StatelessWidget {
  final String text;
  const NeonText(this.text);

  @override
  Widget build(BuildContext context) {
    return Text(
      text,
      style: const TextStyle(
        fontFamily: 'Mr Dafoe', // Or any cursive 80s font
        fontSize: 64,
        color: Colors.white,
        shadows: [
          Shadow(color: Colors.white, blurRadius: 2),
          Shadow(color: Colors.pinkAccent, blurRadius: 5),
          Shadow(color: Colors.pinkAccent, blurRadius: 15),
          Shadow(color: Colors.pinkAccent, blurRadius: 30),
        ],
      ),
    );
  }
}

class SynthwaveScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: const Color(0xFF090014),
      body: Stack(
        children: [
          // Background grid asset
          Positioned(
            bottom: 0,
            left: 0,
            right: 0,
            height: 300,
            child: Image.asset('assets/synth_grid.png', fit: BoxFit.cover),
          ),
          // Foreground UI
          const Center(child: NeonText('Outrun')),
        ],
      ),
    );
  }
}
  • TextStyle accepts a list of Shadow objects. Stack them with exponentially increasing blurRadius values (e.g., 2, 5, 15, 30) to simulate light dispersal.
  • Avoid rendering the perspective grid programmatically using CustomPaint unless you want to do the 3D math manually. Use an asset.

React Native
jsx
// React Native only supports ONE textShadow per Text element natively.
// To create a true neon glow, you must stack identical Text components.

const NeonText = ({ text }) => {
  const baseStyle = {
    fontFamily: 'MrDafoe',
    fontSize: 64,
    color: '#FFF',
    position: 'absolute',
  };

  return (
    <View style={{ alignItems: 'center', height: 80 }}>
      {/* Outer Glow */}
      <Text style={[baseStyle, { textShadowColor: '#FF00FF', textShadowRadius: 30 }]}>{text}</Text>
      {/* Mid Glow */}
      <Text style={[baseStyle, { textShadowColor: '#FF00FF', textShadowRadius: 15 }]}>{text}</Text>
      {/* Core Glow */}
      <Text style={[baseStyle, { textShadowColor: '#FFF', textShadowRadius: 5 }]}>{text}</Text>
      {/* Crisp White Core */}
      <Text style={baseStyle}>{text}</Text>
    </View>
  );
};

const SynthwaveScreen = () => (
  <View style={{ flex: 1, backgroundColor: '#090014', justifyContent: 'center' }}>
    <NeonText text="Outrun" />
    
    <Image 
      source={require('./synth_grid.png')}
      style={{ position: 'absolute', bottom: 0, width: '100%', height: 300, resizeMode: 'cover' }}
    />
  </View>
);
  • React Native limitation: You cannot pass an array of shadows to textShadow.
  • Workaround: Render the exact same <Text> component 3-4 times on top of each other using position: 'absolute', each with a different textShadowRadius to build the bloom.
Jetpack Compose
kotlin
@Composable
fun NeonText(text: String) {
    Text(
        text = text,
        fontSize = 64.sp,
        color = Color.White,
        fontFamily = FontFamily.Cursive,
        // Compose only supports a single Shadow natively on TextStyle
        style = TextStyle(
            shadow = Shadow(
                color = Color(0xFFFF00FF),
                offset = Offset.Zero,
                blurRadius = 30f // Single large blur as fallback
            )
        ),
        // To get stacked blurs, we use Modifier.drawBehind to draw the text repeatedly
    )
}

// Advanced stacked glow approach
@Composable
fun AdvancedNeonText(text: String) {
    Box(contentAlignment = Alignment.Center) {
        // Render layers of text to build the glow
        val blurs = listOf(30f, 15f, 5f)
        blurs.forEach { blur ->
            Text(
                text = text,
                color = Color.Transparent,
                style = TextStyle(
                    shadow = Shadow(Color(0xFFFF00FF), Offset.Zero, blur)
                )
            )
        }
        // Top solid layer
        Text(text = text, color = Color.White)
    }
}
  • Compose Limitation: Like React Native, TextStyle only accepts a single Shadow.
  • Workaround: Stack multiple transparent Text composables inside a Box, each casting a shadow of varying size, topped by the solid white core text.

Do's and Don'ts

  • DO: Italicize fonts to give a sense of speed and forward momentum.
  • DON'T: Use standard, subtle box shadows. If it casts a shadow, it must cast a neon glow instead.

Limitations

  • This is a styling reference and does not replace environment-specific validation, accessibility testing, or expert review.
  • Ensure appropriate contrast ratios and responsive behaviors are verified separately.
