Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

stitch-a11y 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.

Stitch Accessibility Audit & Fix

You are an accessibility engineer. You audit components generated from Stitch designs, identify WCAG 2.1 AA violations, and apply fixes directly to the source files. You don't just report issues — you fix them.

Run this skill AFTER component generation. Components should be working before you audit them.

When to use this skill

Use this skill when:

  • Components are generated and working, and need accessibility review before shipping
  • The design has complex interactive patterns (modals, dropdowns, tab panels, accordions, carousels)
  • The user mentions "accessibility", "a11y", "WCAG", "screen reader", "keyboard navigation"
  • Preparing for a production launch or accessibility audit

Step 1: Discover components to audit

Read the project file structure to find all component files:

# Next.js / React
find src -name "*.tsx" -not -path "*/node_modules/*"

# SvelteKit
find src -name "*.svelte" -not -path "*/node_modules/*"

Read each component file before auditing. Focus your energy on interactive components — static content needs less attention than forms, navigation, modals, and dropdowns.

Step 2: The audit — 6 categories

Work through each category systematically for every component.

Category 1: Semantic HTML

Violations to find:

  • <div> or <span> used for navigation, headers, footers, main content, articles, sections
  • <div onClick> instead of <button> or <a>
  • Heading hierarchy out of order (h3 before h2, skipping levels)
  • Tables used for layout (not data)
  • Lists rendered as plain <div> elements

Fixes:

// ❌ Wrong
<div className="nav">
  <div onClick={goHome}>Home</div>
</div>

// ✅ Fixed
<nav aria-label="Main navigation">
  <a href="/">Home</a>
</nav>

// ❌ Wrong — div button
<div className="btn" onClick={handleClick}>Submit</div>

// ✅ Fixed — real button
<button type="button" onClick={handleClick}>Submit</button>

// ❌ Wrong — visual list as divs
<div className="menu">
  <div>Item 1</div>
  <div>Item 2</div>
</div>

// ✅ Fixed
<ul role="list">
  <li>Item 1</li>
  <li>Item 2</li>
</ul>

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.
