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 5.1 | $0.00028 | $0.01361 |
| Opus 5.5 | $0.00011 | $0.00544 |
| Sonnet 5.5 | $0.00006 | $0.00272 |
| Haiku 4.5 | $0.00003 | $0.00136 |
Grade A, and why
ui-review 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 19d 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.

UI Review Skill
When to Use
- Reviewing a UI implementation
- Checking accessibility compliance
- Validating brand consistency
- Before releasing new UI features
- Finding and fixing design issues in running websites
Scope of Application
- Static sites (HTML/CSS/JS)
- SPA frameworks (React, Vue, Angular, Svelte)
- Full-stack frameworks (Next.js, Nuxt, SvelteKit)
- Any web application (local dev, staging, or production)
Steps
Step 0: Information Gathering
Before reviewing, understand the project context:
| Item | What to Determine |
|---|---|
| Framework | React, Vue, Next.js, etc. |
| Styling Method | CSS, SCSS, Tailwind, CSS-in-JS, CSS Modules |
| Source Location | Where style files and components live |
| Review Scope | Specific pages or entire site |
Detect automatically from workspace files when possible (package.json, tailwind.config.*, next.config.*, etc.).
References: For framework-specific fix patterns see references/framework-fixes.md. For a detailed visual checklist see references/visual-checklist.md.
Step 1: Capture Current State
Document: Screenshot/URL, purpose, target users, requirements.
Step 2: Visual Design Review
Brand Compliance
- Primary color (
<BRAND_PRIMARY>) used for CTAs and accents - Dark color (
<BRAND_DARK>) used for text and headers - Light color (
<BRAND_LIGHT>) used for backgrounds - 60-30-10 color rule followed
- No off-brand colors used
Typography
- Consistent font family
- Proper heading hierarchy (h1 -> h2 -> h3)
- Min 14px body text
- Text contrast meets WCAG AA (4.5:1)
Layout Issues to Detect
| Issue | Description | Severity |
|---|---|---|
| Element Overflow | Content overflows parent or viewport | High |
| Element Overlap | Unintended overlapping | High |
| Alignment Issues | Grid or flex alignment problems | Medium |
| Inconsistent Spacing | Padding/margin inconsistencies | Medium |
| Text Clipping | Long text not handled properly | Medium |
| Font Inconsistency | Mixed font families | Medium |
| Color Inconsistency | Non-unified brand colors | Medium |
What ships with it
2 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.
