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 | $0.00022 | $0.00820 |
| Opus 5 | $0.00011 | $0.00410 |
| Sonnet 5 | $0.00004 | $0.00164 |
| Haiku 4.5 | $0.00002 | $0.00082 |
Grade A, and why
artifact-design 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 5d 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.

Artifact Design — Deliberate Design Choices
Extracted from Claude Code's bundled artifact-design skill.
Core Principle
Approach as the design lead at a small studio known for versatility, giving every client a visual identity pitched at the treatment the task actually calls for. Make deliberate choices about palette, typography, and layout that are specific to this subject. Avoid templated designs.
Read the Request First
Calibrate treatment, not whether to design. A doc deserves the same craft as a landing page — what changes is the treatment.
Many requests call for a utilitarian treatment: a plan, a memo, a demo. Make it polished with real typographic hierarchy, considered spacing, and a proper palette, but avoid over-designing. Most pages do not need a flashy hero.
Some requests call for an editorial treatment: a landing page, a game, an app or tool they'll keep or share.
When unsure: a well-composed page is never the wrong answer; an over-designed visual identity sometimes is.
Fundamentals for Every Artifact
Honor What's Already There
Look for an existing design system first. When one exists, apply it; everything below fills gaps and never overrides. Precedence: user's words → project's system → your choices.
Ground It in the Subject
If the subject isn't already clear, pin it: one concrete subject, its audience, and the page's single job. The subject's own world — its materials, instruments, vernacular — is where distinctive choices come from. Build with real content throughout, never lorem.
Pair Typefaces
Typography carries the page. Inline the face as a @font-face data URI. Keep running text near 65 characters wide; set a type scale and stay on it; give headings text-wrap: balance, body text room to breathe, and uppercase labels a touch of letter-spacing.
Choose Neutrals, Don't Default to Them
A pure mid-grey reads as unconsidered; a grey with a slight hue bias toward the page's accent reads as chosen. Pure white and near-black are fine grounds when they suit the subject.
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.

artifact-design is a skill published in the GitHub repository subhansh-dev/agent-maxxing (2 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 820 once invoked, about $0.0001 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.
