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 | $0.00050 | $0.00359 |
| Opus 5.5 | $0.00020 | $0.00144 |
| Sonnet 5.5 | $0.00010 | $0.00072 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
creative-web 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 1mo 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.
What it actually says
Creative Web
Entry criterion
Creative technology must communicate product meaning, spatial information, material character, or memorable brand identity. Decorative complexity alone is not sufficient.
Router
Read references/capability-matrix-2026.md first. Read references/three-r3f.md for programmable 3D and references/rive-spline-theatre.md for authored interactive assets/timelines.
- Three.js: low-level scene/render/shader control.
- React Three Fiber: React-native Three.js scene architecture.
- Rive: interactive vector animation and state machines.
- Spline: designer-authored 3D scenes and web integration.
- Theatre.js: timeline authoring and synchronized scene/property animation.
- SVG: first choice for many crisp illustrative/mask/path effects.
- Canvas/shader: custom computation when visual behavior cannot be expressed cleanly in DOM/SVG.
Progressive enhancement contract
- Essential text, navigation and controls stay in semantic DOM.
- Define a still/static fallback for 3D/canvas/vector scenes.
- Degrade particle count, DPR, post-processing, shadows and continuous loops on constrained devices.
- Lazy-load heavy scenes below the fold or behind interaction.
- Stop or reduce rendering when offscreen.
- Respect reduced motion.
Acceptance
The creative layer must strengthen the design POV enough to justify load, runtime and QA cost.
What ships with it
4 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.

creative-web is a skill published in the GitHub repository Lrinvl1203/world-class-web-design-os (8 stars, last pushed 22d ago), licensed MIT. It adds 50 tokens to every session and 359 once invoked, about $0.0002 per session on Opus 5.5. 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.
