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 | $0.00043 | $0.01559 |
| Opus 5 | $0.00022 | $0.00779 |
| Sonnet 5 | $0.00009 | $0.00312 |
| Haiku 4.5 | $0.00004 | $0.00156 |
Grade A, and why
web-typography 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 10d 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
The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Typography
Readable, hierarchically structured, and performant text design for the web.
Scope
Use this skill when: You are selecting fonts, defining font pairings, building typographic scales, setting line heights and line lengths, implementing fluid typography, or auditing existing typography for quality.
Principles
1. Typography Is User Interface
Text is the primary information layer. Typographic design determines whether content is read, scanned, or ignored.
2. Readability Before Aesthetics
A font must first be readable. If the user focuses on the formatting instead of the content, the typography has failed.
3. Create Hierarchy Through Typography
Different sizes, weights, and styles form a clear information hierarchy. The reading flow is typographically directed.
4. Fewer Fonts -- Greater Impact
Maximum 2-3 font families per project. Each additional font increases load time and reduces coherence.
5. Use Emotional Impact Intentionally
Sans-serif grotesque = modern/neutral. Serif = classic/trustworthy. Display font = expressive/unique.
Rules
Font Selection
- DO: Choose fonts matching the brand identity. Corporate: Inter, Geist, DM Sans. Creative: display fonts.
- DO: Verify character set coverage: umlauts, special characters (mandatory for German-language content).
- DO: Use variable fonts when available (one file instead of 6+).
- DO: Prefer self-hosted WOFF2 (GDPR: no Google Fonts CDN).
- DON'T: Use more than 2 font families for body + headings. A third only for accents.
- DON'T: Use Comic Sans, Papyrus, or Impact in professional contexts -- never.
Font Pairing
- DO: Combine with contrast: serif for headlines + sans for body (or vice versa).
- DO: Match similar x-heights between pairs for optical harmony.
- DO: Use proven combinations: Playfair Display + Source Sans Pro, Poppins + Inter.
- DON'T: Combine two similar sans-serifs. Lack of contrast appears indecisive.
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.

web-typography is a skill published in the GitHub repository flitzrrr/frontend-design-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 43 tokens to every session and 1,559 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 2026-08-31.
