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 | $0.00067 | $0.00927 |
| Opus 5 | $0.00034 | $0.00464 |
| Sonnet 5 | $0.00013 | $0.00185 |
| Haiku 4.5 | $0.00007 | $0.00093 |
Grade A, and why
typography-scale-builder 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 9d 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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Typography Scale Builder
Typography is the design system's skeleton: most products that look "off" have inconsistent type long before they have bad colors. Build the scale as a system with roles and math, then make the codebase actually use it. Input: the chosen fonts (or run font-pairing-suggester first), the product type (marketing site, dense app UI, long-form editorial), and the target range of devices.
Workflow
- Audit what exists. Inventory every font-size, line-height, letter-spacing, and font-weight in the codebase. The typical finding -- 23 font sizes, 9 of them within 2px of each other -- is the case for the system. Map which are actually distinct roles vs. accumulated drift.
- Choose the scale math. Base size (16px body floor for marketing/editorial; 13-14px acceptable for dense app UI) and ratio -- modest for UI-heavy products (1.125-1.2, more usable steps, less drama), larger for marketing/editorial (1.25-1.333, real hierarchy). Fluid by default for marketing sites:
clamp()per step so headings scale between viewport bounds without breakpoint jumps; fixed steps are fine for app UI. - Set the companions per step -- the part single-number "scales" skip: line-height tightens as size grows (body ~1.5-1.6, headings down to 1.1-1.2 at display sizes); letter-spacing goes negative at display sizes (-1% to -2.5%) and slightly positive for small caps/labels; weight roles per font (which weight is body, emphasis, heading, display -- and which loaded weights get deleted because nothing uses them).
- Define the roles. Semantic tokens, not size names:
display,h1-h4,body-lg,body,body-sm,caption,overline,code. Each role = size step + line-height + tracking + weight + family, as one token. Components consume roles; nobody composes raw steps. - Vertical rhythm. Spacing-after rules per role (heading margins proportional to their size, paragraph spacing from body line-height),
text-wrap: balanceon headings, and measure limits (65-75ch for body prose) so line length stays readable at every viewport. - Export and retrofit.
typography-tokens.json, TailwindfontSizeconfig (size + line-height + tracking tuples per role; v4@theme),typography.csswith role classes, andTYPOGRAPHY.md. Then map the step-1 inventory onto roles and replace -- with a per-case flag on anything that does not cleanly map (it is either a missing role or drift to delete).
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.

typography-scale-builder is a skill published in the GitHub repository OneWave-AI/claude-skills (291 stars, last pushed 1mo ago), licensed MIT. It adds 67 tokens to every session and 927 once invoked, about $0.0003 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 2026-09-03.
