Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00137 | $0.03276 |
| Opus 5 | $0.00068 | $0.01638 |
| Sonnet 5 | $0.00027 | $0.00655 |
| Haiku 4.5 | $0.00014 | $0.00328 |
Grade A, and why
design-business-card 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
The opening of the file, as written. The whole thing — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: business-card
Produces a single self-contained HTML file containing two pixel-exact 1050×600 canvases — the front and back of a standard 3.5×2 inch business card at 300dpi. Print-ready dimensions; bleed and crop notes documented at the end of the file.
This skill is the most extreme reduction test in the platform-skills set. A business card has ~6 square inches of total real estate; the brand must speak with nearly no text. If the brand can't hold its identity at this scale, the design system has a problem worth surfacing.
When to use
- User needs printed business cards (or digital equivalents — Apple Wallet, Linktree alternative)
- A
DESIGN.mdexists for the brand
Inputs
- Required: brand slug, name, title/role
- Required: primary contact (email OR URL — pick the one most likely to lead to a conversation)
- Optional: secondary contact (the other of email/URL)
- Optional: location (city · timezone)
- Optional: secondary handle (e.g. GitHub for engineering brands)
Output
./design/<brand-slug>/artifacts/business-card-YYYY-MM-DD-<slug>.html
Steps
1. Verify brand exists
test -f ./design/<brand-slug>/tokens.css
2. Gather the brief
Ask in one message:
1. Name — as it should appear on the card
2. Title / role — short, sentence-case (no periods on titles — they're labels not sentences)
3. Primary contact — pick ONE: email OR URL (the one you most want to receive)
4. Optional secondary contact — the other one
5. Optional location — city · timezone (e.g. "Louisville · GMT−5")
6. Optional secondary handle — e.g. "github.com/handle" for engineering brands
If the user wants more than 4 lines of text on the front, push back: "Business cards work at 4 lines max. What's essential?"
3. Pick variation — FRONT and BACK can use different archetypes
This is the rare skill where the front and back can take DIFFERENT visual approaches because they serve different functions (front = info; back = mark/identity):
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.
