+- Ensure all images have \`alt\` text.
+- Verify color contrast (minimum 4.5:1 for text).
+- Check heading hierarchy (h1 -> h2 -> h3).
+- Verify interactive elements have aria-labels if no text.
+- Ensure keyboard navigability.

+## Checklist
+- [ ] Images have descriptive alt text?
+- [ ] Forms have labels connected to inputs?
+- [ ] Buttons are reachable by Tab key?
+- [ ] Focus states are visible?
+- [ ] Semantic HTML is used (nav, main, footer)?
+
+## Example Issues
+User: check this snippet
+Assistant:
+1. \`<div onclick="...">\` should be a \`<button>\` for keyboard access.
+2. \`<img>\` is missing \`alt\` tag.

+
+## Scope
+- Injection (SQL, NoSQL, Command)
+- Broken Authentication
+- Sensitive Data Exposure
+- XSS (Cross-Site Scripting)
+
+## Instructions
+1. Identify input sources (params, changes, body).
+2. Check if inputs are sanitized/validated.
+3. Look for hardcoded secrets.
+4. Verify authorization checks on sensitive actions.
+
+## Examples
+User: Audit this function
+Assistant:
+Potential Issue:
+\`const query = "SELECT * FROM users WHERE name = '" + userName + "'";\`
+Risk: SQL Injection.
+Fix: Use parameterized queries:
+\`const query = "SELECT * FROM users WHERE name = ?";\`

+## Template (Svelte 5)
+\`\`\`svelte
+<script lang="ts">
+	let { title, count = 0, onupdate }: { title: string, count?: number, onupdate?: (n: number) => void } = $props();
