+# Markstream Svelte
+
+## Overview
+
+Integrate Markstream using Svelte 5 runes and SvelteKit-safe browser boundaries.
+
+## When to Use
+
+Use for Svelte 5 or SvelteKit package setup, streaming state, workers, or scoped custom components. Svelte 4 is unsupported.
+
+## Workflow
+
+Before changing dependencies or source files, inspect the existing package manager and project conventions, preview the intended edits, and obtain explicit user approval.
+
+1. Confirm Svelte 5 and acceptance of a beta package.
+2. Install only requested peers; import package CSS after resets and KaTeX CSS only for math.
+3. Start with `<MarkdownRender {content} />` and smooth streaming `auto`.
+4. For live chat disable fade and opt into the cursor; on completion set `final`, disable pacing/cursor, and enable fade only if desired.
+5. Use `nodes` only for worker-owned parsing or shared AST state.
+6. Use `$props()` and callbacks. Configure KaTeX or Mermaid workers only when requested.
+7. Prefer renderer-local `customComponents`; use scoped registration only when sharing is intentional.
+8. Keep browser-only workers behind SvelteKit client boundaries; validate with `svelte-check`, build, or e2e.
+
+## Example
+
+```svelte
+<script lang="ts">
+  import MarkdownRender from 'markstream-svelte'
+  import 'markstream-svelte/index.css'
+
+  let { content, isDone }: { content: string; isDone: boolean } = $props()
+</script>
+
+<MarkdownRender
+  {content}
+  final={isDone}
+  fade={isDone}
+  typewriter={!isDone}
+  smoothStreaming={isDone ? false : 'auto'}
+  htmlPolicy="safe"
+/>
+```
+
+## Limitations
+
+- Svelte 4 is unsupported and the package is beta.
+- Workers and heavy peers require client-side bundler support.
+- This skill does not migrate unrelated Svelte architecture.
+
+## Security & Safety Notes
+
+Keep safe HTML and strict Mermaid defaults. Review dependencies and never run browser-only peers during SSR.
