Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00880 |
| Opus 5 | $0.00021 | $0.00440 |
| Sonnet 5 | $0.00008 | $0.00176 |
| Haiku 4.5 | $0.00004 | $0.00088 |
Grade A, and why
spacing-scale scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

Spacing Scale Generator
Overview
Generate consistent spacing scales using a base value and ratio. Creates exponentially distributed values centered around a base unit for harmonious layouts.
When to Use
- Setting up spacing tokens for a new project
- Standardizing padding and margin values
- Creating a gap/grid system
- Migrating from arbitrary spacing to tokens
Quick Reference
| Naming Style | Example Names | Best For |
|---|---|---|
| T-shirt | xs, sm, md, lg, xl | Semantic, readable |
| Numeric | 100, 200, 300... | Precise, extensible |
| Unit | When to Use |
|---|---|
| px | Fixed layouts, pixel-perfect designs |
| rem | Scalable, respects user font settings |
| em | Component-relative spacing |
The Process
- Get base value: Default 4px or 0.25rem (common base unit)
- Get ratio: How much each step grows (1.5 is balanced, 2 is dramatic)
- Ask steps: How many spacing values (8-12 is typical)
- Ask naming: T-shirt sizes (xs, sm, md, lg) or numeric (100, 200, 300)?
- Ask unit: px, rem, or em?
- Ask format: CSS, Tailwind, or JSON?
- Generate: Create scale centered on base, expanding in both directions
Common Ratios
| Ratio | Character | Example (base 4px) |
|---|---|---|
| 1.25 | Tight | 2, 2.5, 3, 4, 5, 6, 8 |
| 1.5 | Balanced | 1.8, 2.7, 4, 6, 9, 13.5 |
| 1.618 | Golden | 1.5, 2.5, 4, 6.5, 10.5, 17 |
| 2 | Dramatic | 1, 2, 4, 8, 16, 32 |
Output Formats
CSS Custom Properties:
:root {
--spacing-xs: 2px;

'md': '8px',
'lg': '16px',
'xl': '32px',
}
}
}
JSON Tokens:
{

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

spacing-scale is a skill published in the GitHub repository dylantarre/design-system-skills (42 stars, last pushed 8mo ago), licensed MIT. It adds 42 tokens to every session and 880 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
