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 | $0.00143 | $0.02722 |
| Opus 5 | $0.00072 | $0.01361 |
| Sonnet 5 | $0.00029 | $0.00544 |
| Haiku 4.5 | $0.00014 | $0.00272 |
Grade A, and why
web-design-guidelines 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 8d 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.

Web Design Guidelines
Use this skill when the question is "how good is this interface overall, what is creating friction, and what should we fix first?"
This is the repo's broad interface audit / design-review anchor. It is not just a vendor-rule fetcher and it is not a replacement for specialized neighboring skills.
Read references/review-modes-and-categories.md before handling a broad page or flow review.
Read references/handoff-boundaries.md when deciding whether the work belongs here, web-accessibility, responsive-design, ui-component-patterns, design-system, or react-best-practices.
Read references/ui-audit-packet-template.md before writing a final review packet.
When to use this skill
- Review a landing page, dashboard, signup flow, settings page, or marketing site for broad interface quality
- Turn "review my UI" or "audit this UX" into a structured audit instead of scattered opinions
- Judge hierarchy, clarity, spacing, consistency, component-state quality, CTA emphasis, and task friction together
- Check whether a screen or flow is ready for implementation, release, or stakeholder review
- Compare a page against broad interface heuristics and practical implementation guidelines
- Convert mixed findings into one prioritized UI audit packet with explicit handoffs
When not to use this skill
- The main task is accessibility remediation, keyboard/focus behavior, labels, semantic HTML, or manual-vs-automated WCAG verification → use
web-accessibility - The main task is viewport adaptation, overflow, breakpoint strategy, or container-aware layout behavior → use
responsive-design - The main task is reusable primitive / slot / variant API design or controlled-vs-uncontrolled component architecture → use
ui-component-patterns - The main task is system-level token governance, visual language, or component-library foundations → use
design-system - The main task is React rendering, hydration, state churn, bundle/runtime behavior, or performance debugging → use
react-best-practicesorperformance-optimization - The task is only to paste automated tool output with no design judgment; run the tool directly, then return here to interpret and prioritize
What ships with it
5 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.

web-design-guidelines is a skill published in the GitHub repository Coinyak/onchainai (1 stars, last pushed 1mo ago), licensed MIT. It adds 143 tokens to every session and 2,722 once invoked, about $0.0007 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.
