What it does

Retro Design is an agent skill from sickn33/agentic-awesome-skills. Web and App implementation guide for Retro Design (60s-80s). Trigger when user wants vintage aesthetics, warm muted colors, and nostalgic layouts.

Its SKILL.md is about 2.5k 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. 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 vintage aesthetics
  • Warm muted colors
  • Nostalgic layouts

Example prompts

  • “/retro-design”

Workflow steps

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

  1. Warm, Analog Color Palettes: Colors look faded by the sun or printed on aged paper.
  2. Texture and Noise: A slight grain overlay to simulate film or old print media.
  3. Classic Typography Pairings: Heavy, groovy display fonts paired with typewriter or classic serif body copy.

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. 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

Retro Design loads about 2.5k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 330 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
~2.5k

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.

Retro Design

"A warm, analog feeling. Nostalgia through muted tones, grain, and classic typography."

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. Warm, Analog Color Palettes: Colors look faded by the sun or printed on aged paper.
  2. Texture and Noise: A slight grain overlay to simulate film or old print media.
  3. Classic Typography Pairings: Heavy, groovy display fonts paired with typewriter or classic serif body copy.

Visual DNA

  • Colors: Monochromatic Brown or warm, faded palettes (mustard yellow, burnt orange, sage green, off-white).
  • Typography: Display fonts like Cooper Black, Garamond, or Courier.
  • Styling: Badges, stamps, wavy borders, and halftone patterns.

Web Implementation

  • Use CSS filters and background noise images to create texture.
  • CSS Example:
css
body {
  background-color: #F4E8D1; /* Aged paper */
  color: #3E2723; /* Deep brown ink */
  font-family: 'Georgia', serif;
  
  /* Apply a subtle noise overlay using a pseudo-element or background image */
  background-image: url('noise-texture.png');
  background-blend-mode: multiply;
}

.retro-header {
  font-family: 'Cooper Black', serif;
  font-size: 4rem;
  color: #D35400; /* Burnt orange */
  text-shadow: 2px 2px 0px #F1C40F; /* Mustard yellow drop shadow */
  letter-spacing: -1px;
}

.retro-card {
  background-color: #FFF3E0;
  border: 2px solid #3E2723;
  border-radius: 12px;
  padding: 24px;
  
  /* Vintage offset shadow */
  box-shadow: 8px 8px 0px #795548;
}

.retro-badge {
  display: inline-block;
  background-color: #E74C3C;
  color: #F4E8D1;
  font-family: monospace;
  font-weight: bold;
  padding: 8px 16px;
  border-radius: 50%; /* Make it look like a sticker */
  transform: rotate(-10deg);
}

App Implementation

SwiftUI
swift
struct RetroCard: View {
    let paperColor = Color(red: 0.96, green: 0.91, blue: 0.82) // #F4E8D1
    let inkColor = Color(red: 0.24, green: 0.15, blue: 0.14) // #3E2723
    
    var body: some View {
        ZStack {
            paperColor.ignoresSafeArea()
            
            // Optional: Noise texture
            Image("film_grain")
                .resizable()
                .blendMode(.multiply)
                .opacity(0.3)
                .ignoresSafeArea()
            
            VStack(alignment: .leading, spacing: 24) {
                Text("RETRO DESIGN")
                    .font(.custom("Cooper Black", size: 36))
                    .foregroundColor(Color(red: 0.83, green: 0.33, blue: 0.0)) // #D35400
                    .shadow(color: Color(red: 0.95, green: 0.77, blue: 0.06), radius: 0, x: 2, y: 2)
                
                Text("Analog warmth and classic typography.")
                    .font(.custom("Georgia", size: 18))
                    .foregroundColor(inkColor)
            }
            .padding(32)
            .background(Color(red: 1.0, green: 0.95, blue: 0.88))
            .cornerRadius(12)
            .overlay(
                RoundedRectangle(cornerRadius: 12)
                    .stroke(inkColor, lineWidth: 2)
            )
            // Vintage solid offset shadow
            .shadow(color: Color(red: 0.47, green: 0.33, blue: 0.28), radius: 0, x: 8, y: 8)
        }
    }
}
  • A grain texture image can be overlaid using .blendMode(.multiply). Be aware of memory usage with full-screen textures.
  • Use .shadow(radius: 0) to create the hard offset shadows typical of 70s print media.
  • Custom fonts like Cooper Black are absolutely required.

  }
}
  • Wrap backgrounds in a Stack to place a semi-transparent film grain asset over the solid color.
  • Drop shadows for text and containers must have blurRadius: 0 to emulate offset misregistered ink prints.

  return (
    <ImageBackground 
      source={require('./film_grain.png')}

};
  • Use ImageBackground on the root view for the grain.
  • Android's elevation cannot do unblurred offset shadows natively. Use react-native-drop-shadow for perfect retro shadows on Android.

                Text("Analog warmth and classic typography.",
                    fontFamily = FontFamily.Serif,
                    fontSize = 18.sp,
                    color = inkColor)
            }
        }
    }
}
  • Native Modifier.shadow creates soft blurs. Use Modifier.drawBehind to draw an offset drawRoundRect for the hard retro shadow block.
  • Text shadows support hard offsets perfectly via Shadow(color, offset, blurRadius = 0f).

Do's and Don'ts

  • DO: Use slightly off-white backgrounds (cream, beige) instead of pure #FFFFFF to simulate aged paper.
  • DON'T: Use sleek, modern geometric sans-serifs or tech-focused neon colors.

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.
