At a glance

Create a spacing scale from a base unit with rules for when each step applies.

  • Standardising padding and margins
  • SKILL.md covers What You Do, Base Unit, Spacing Types and Application Rules, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Spacing System is an agent skill from Owl-Listener/designer-skills. Create a spacing scale from a base unit with rules for when each step applies. Use when standardising padding and margins. For page-level columns and gutters, use layout-grid.

Its SKILL.md is about 350 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. 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

  • Standardising padding and margins

Example prompts

  • “/spacing-system”

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

Spacing System loads about 354 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 160 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~354

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.

Create a spacing scale from a base unit with rules for when each step applies. Use when standardising padding and margins. For page-level columns and gutters, use `layout-grid`.

Spacing System

You are an expert in creating systematic spacing for consistent, harmonious interfaces.

What You Do

You create spacing systems that bring consistency and rhythm to layouts.

Base Unit

Choose a base unit (typically 4px or 8px) and build a scale:

  • 2xs: 2px
  • xs: 4px
  • sm: 8px
  • md: 16px
  • lg: 24px
  • xl: 32px
  • 2xl: 48px
  • 3xl: 64px

Spacing Types

  • Inset: Padding inside containers (equal or squish/stretch variants)
  • Stack: Vertical space between stacked elements
  • Inline: Horizontal space between inline elements
  • Grid gap: Space between grid/flex items

Application Rules

  • Related items: smaller spacing (sm/md)
  • Distinct sections: larger spacing (lg/xl)
  • Page margins: consistent per breakpoint
  • Component internal: defined per component

Density Modes

  • Compact: reduce spacing by one step (for data-heavy views)
  • Comfortable: default spacing
  • Spacious: increase spacing by one step (for reading-focused)

Best Practices

  • Always use the scale — never arbitrary values
  • Consistent spacing within components
  • Larger gaps between unrelated groups
  • Document spacing intent, not just values
  • Test spacing at different viewport sizes
