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.

What it costs to keep this loaded
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 | $0.00122 | $0.02178 |
| Opus 5 | $0.00061 | $0.01089 |
| Sonnet 5 | $0.00024 | $0.00436 |
| Haiku 4.5 | $0.00012 | $0.00218 |
Grade A, and why
design-standards 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 8d 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.

Design Standards
Production design standards for any web project. Stack-agnostic. Tool-agnostic. Covers tokens, contrast, hierarchy, spacing, mobile rules, and the pre-ship checklist.
This skill complements brand-identity (which defines the visual system) and brand-style-guide (which documents it). This skill is for the day-to-day work of applying those standards in real components and pages.
When to use
- Building a new page, section, or component
- Reviewing UI for quality, accessibility, or consistency
- Setting up design tokens for a new project
- Fixing layout, contrast, or hierarchy issues
- Establishing a button or form standard
- Pre-ship design review
When NOT to use
- Defining a brand identity from scratch (use
brand-identity) - Documenting a finished brand system (use
brand-style-guide) - Building a formal component library (use
design-system) - Frontend code architecture (use
frontend-component-build) - Accessibility-only audits with WCAG remediation (use
accessibility-audit)
Required inputs
- The page or component being built or reviewed
- The brand's design tokens (colors, type, spacing) - or willingness to define them
- The target devices and viewports
If brand tokens are undefined, define a working set first using the template in references/design-tokens-template.md.
The framework: 6 standards
Six standards apply to every piece of UI. Hold the line on these and most design problems disappear.
1. Design tokens
Every project needs tokens defined before any UI gets built. Tokens are the source of truth.
Color tokens (minimum):
- Primary brand color
- Primary hover (typically 15 to 25 percent darker)
- Background variants (surface, alt-section, hero/dark, footer)
- Text scale (heading, body, muted, on-dark)
- Semantic (success, warning, error, info)
Spacing tokens:
- A consistent scale (e.g., 4, 8, 12, 16, 24, 32, 48, 64, 96)
- Page max-width
- Section vertical padding (large, medium, small)
- Card padding
- Grid gaps
What ships with it
3 files 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.

design-standards is a skill published in the GitHub repository rampstackco/claude-skills (826 stars, last pushed 10d ago), licensed MIT. It adds 122 tokens to every session and 2,178 once invoked, about $0.0006 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.
