Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned s-hiraoku/synapse-a2a at 844eb75d92.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill assists with frontend design, focusing on creating interfaces that have intentional aesthetics and a professional execution – avoiding generic or template-like looks. It guides the AI agent through a structured design process, emphasizing thoughtful typography, color system architecture using CSS custom properties, and appropriate use of motion and animation. The goal is to produce high-quality user experiences with a distinct visual personality.

When to use it

  • When designing new frontend UIs where a unique aesthetic is desired.
  • To refine existing designs that feel generic or lack visual impact.
  • For projects requiring careful attention to typography, color palettes, and accessibility (WCAG).
  • When needing help establishing a consistent design system based on CSS custom properties.
  • To ensure motion and animation are implemented responsibly, respecting user preferences for reduced motion.

Key capabilities

  • Design Process Guidance: Provides questions to consider before coding, covering purpose, tone, constraints, and signature elements.
  • Typography Expertise: Offers advice on font selection (avoiding defaults) and typographic details like tabular numbers, balanced headings, and proper ellipsis characters.
  • Color System Architecture: Guides the creation of CSS custom property-based themes with semantic naming conventions and dark mode support.
  • Motion & Animation Rules: Provides guidelines for responsible animation implementation, respecting user preferences and optimizing performance.
  • Text Overflow Handling: Includes code snippets for single-line truncation, multi-line clamping, and flex child management.

Example prompts

  • "Design a landing page with a retro-futuristic aesthetic."
  • "Help me choose fonts that reflect a luxury brand identity."
  • "Generate CSS custom properties for a dark mode theme based on these colors: [list of colors]."
  • “Show me how to truncate text in a single line using CSS.”

Tips & gotchas

  • The skill emphasizes committing to a design direction, even if it has flaws – timid designs are discouraged.
  • It's crucial to consider accessibility requirements (WCAG) when designing and implementing color palettes and typography.
  • The skill focuses on frontend UI design; it is not intended for broader development tasks.
