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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00156 | $0.05008 |
| Opus 5 | $0.00078 | $0.02504 |
| Sonnet 5 | $0.00031 | $0.01002 |
| Haiku 4.5 | $0.00016 | $0.00501 |
Grade A, and why
website-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 3d 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 — 318 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Website Builder
Generate production-ready websites through a design interview: read the brief, ask only about genuine gaps, propose distinct design directions, prove the chosen one with a style preview, then build. Coordinates with copywriting, brand, fonts, section, and audit skills.
Working Alongside CLAUDE.md
This skill is the orchestrator referenced by Hakuto's CLAUDE.md. Follow CLAUDE.md's "Mandatory Workflow" (the 7-step index.css → Layout.astro → Project Plan → Components flow) alongside this skill's design workflows. CLAUDE.md is always loaded; this skill adds the conversational, design-aware layer on top of that mechanical sequence.
When the two overlap, CLAUDE.md owns the how (which files to touch, what conventions to follow) and this skill owns the what (which direction, which content strategy, when to invoke siblings).
Technical Constraints
These rules are enforced by CLAUDE.md and apply to every page this skill produces. See CLAUDE.md for full details.
- Tailwind CSS v4 — config lives in
src/index.cssvia@theme {}, nottailwind.config.mjs(delete that file if present). className(notclass) on React/shadcn components —<Button className="...">is correct;<Button class="...">is a TypeScript error. Native HTML in.astrokeepsclass.- Astro Fonts API for custom fonts —
experimental.fonts(5.x) or top-levelfonts(6+) inastro.config.mjs. Never use@importor@font-facefor custom fonts. ALWAYS invoke thefontsskill when custom fonts are involved. - Cloudflare adapter
imageService: "custom"with noimage.servicekey, so Astro's sharp default survives. Both"compile"and"passthrough"replace sharp —"compile"does so despite the name. <Picture>for local images,<img>for external URLs — local assets go throughastro:assetsfor WebP/responsive widths. Unsplash and other external URLs use plain<img>.- Right-size every local image —
width={W} widths={[W, W * 2]} sizes="…", all three: withoutwidthsAstro emits nosrcsetand thesizesis inert. Omitheightunless a crop is intended — a pair that disagrees with the source ratio makes sharp crop.

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.

website-builder is a skill published in the GitHub repository teamniteo/hakuto (5 stars, last pushed 9d ago), licensed MIT. It adds 156 tokens to every session and 5,008 once invoked, about $0.0008 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.
