What it does

Layout Grid is an agent skill from Owl-Listener/designer-skills. Define a responsive grid — columns, gutters, margins, and breakpoint behaviour. Use when establishing page structure. For the spacing scale inside components use spacing-system; for cross-device behaviour use responsive-design.

Its SKILL.md is about 400 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 Frontend & Design, covering Responsive design. The repository describes itself as: Designer Skills Collection: agentic skills, commands, and plugins for design — from research to systems, UI, interaction, and delivery. The licence is MIT.

When your agent uses it

  • Establishing page structure
  • Tasks that involve Responsive design

Example prompts

  • “/layout-grid”

What it can do on your machine

Read from SKILL.md and the folder at commit 9a6930c. 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

Layout Grid loads about 404 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 173 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~404

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.

Layout Grid

You are an expert in layout grid systems for digital product design.

What You Do

You define responsive grid systems that create consistent, flexible page layouts across breakpoints.

Grid Anatomy

  • Columns: Typically 4 (mobile), 8 (tablet), 12 (desktop)
  • Gutters: Space between columns (16px, 24px, or 32px typical)
  • Margins: Outer page margins (16px mobile, 24-48px desktop)
  • Breakpoints: Points where layout adapts (e.g., 375, 768, 1024, 1440px)

Grid Types

  • Column grid: Equal columns for general layout
  • Modular grid: Columns + rows creating modules
  • Baseline grid: Vertical rhythm alignment (4px or 8px)
  • Compound grid: Overlapping grids for complex layouts

Responsive Behavior

  • Fluid: columns stretch proportionally
  • Fixed: max-width container with centered content
  • Adaptive: distinct layouts per breakpoint
  • Column dropping: reduce columns at smaller sizes

Common Patterns

  • Full-bleed: content spans entire viewport
  • Contained: max-width with margins
  • Asymmetric: sidebar + main content
  • Card grids: auto-fill responsive cards

Best Practices

  • Use consistent gutters and margins
  • Align content to the grid, not arbitrarily
  • Test at every breakpoint, not just the extremes
  • Document grid specs for developers
  • Allow intentional grid-breaking for emphasis
