What it does

Responsive Design is an agent skill from wshobson/agents. Implement modern responsive layouts using container queries, fluid typography, CSS Grid, and mobile-first breakpoint strategies. Use when building adaptive interfaces, implementing fluid layouts, or creating component-level responsive behavior.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/breakpoint-strategies.md`, `references/container-queries.md` and `references/details.md`).

It sits in Frontend & Design, covering Responsive design. The repository describes itself as: Multi-harness agentic plugin marketplace for Claude Code, Codex, Cursor, OpenCode, GitHub Copilot, Google Antigravity, and Pi. The licence is MIT.

When your agent uses it

  • Building adaptive interfaces
  • Implementing fluid layouts
  • Creating component-level responsive behavior

Example prompts

  • “/responsive-design”

Workflow steps

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

  1. Mobile-First: Start with mobile styles, enhance for larger screens
  2. Content Breakpoints: Set breakpoints based on content, not devices
  3. Fluid Over Fixed: Use fluid values for typography and spacing
  4. Container Queries: Use for component-level responsiveness
  5. Test Real Devices: Simulators don't catch all issues
  6. Performance: Optimize images, lazy load off-screen content
  7. Touch Targets: Maintain 44x44px minimum on mobile
  8. Logical Properties: Use inline/block for internationalization

What it can do on your machine

Read from SKILL.md and the folder at commit 46891e7. 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.

    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

Responsive Design loads about 498 tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 215 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~498
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

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.

Implement modern responsive layouts using container queries, fluid typography, CSS Grid, and mobile-first breakpoint strategies. Use when building adaptive interfaces, implementing fluid layouts, or creating component-level responsive behavior.

Responsive Design

Master modern responsive design techniques to create interfaces that adapt seamlessly across all screen sizes and device contexts.

When to Use This Skill

  • Implementing mobile-first responsive layouts
  • Using container queries for component-based responsiveness
  • Creating fluid typography and spacing scales
  • Building complex layouts with CSS Grid and Flexbox
  • Designing breakpoint strategies for design systems
  • Implementing responsive images and media
  • Creating adaptive navigation patterns
  • Building responsive tables and data displays

Detailed patterns and worked examples

Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.

Best Practices

  1. Mobile-First: Start with mobile styles, enhance for larger screens
  2. Content Breakpoints: Set breakpoints based on content, not devices
  3. Fluid Over Fixed: Use fluid values for typography and spacing
  4. Container Queries: Use for component-level responsiveness
  5. Test Real Devices: Simulators don't catch all issues
  6. Performance: Optimize images, lazy load off-screen content
  7. Touch Targets: Maintain 44x44px minimum on mobile
  8. Logical Properties: Use inline/block for internationalization

Common Issues

  • Horizontal Overflow: Content breaking out of viewport
  • Fixed Widths: Using px instead of relative units
  • Viewport Height: 100vh issues on mobile browsers
  • Font Size: Text too small on mobile
  • Touch Targets: Buttons too small to tap accurately
  • Aspect Ratio: Images squishing or stretching
  • Z-Index Stacking: Overlays breaking on different screens
