What this skill does
# Vicinae Extensions
Extensions for the Vicinae launcher using TypeScript and React. Two command types: **view** commands display React UI, **no-view** commands execute actions without UI.
## Creating an Extension
Recommended: use Vicinae's built-in "Create Extension" command.
Manual setup:
```bash
mkdir my-extension && cd my-extension
npm init -y
npm install @vicinae/api typescript @types/react @types/node
mkdir src && touch src/command.tsx
```
## Manifest (package.json)
```json
{
"name": "my-extension",
"title": "My Extension",
"version": "1.0.0",
"commands": [
{
"name": "my-command",
"title": "My Command",
"description": "What this command does",
"mode": "view"
}
],
"dependencies": { "@vicinae/api": "^0.8.2" }
}
```
## View Commands (src/command.tsx)
```tsx
import { List, ActionPanel, Action, Icon } from "@vicinae/api";
export default function MyCommand() {
return (
<List searchBarPlaceholder="Search items...">
<List.Item
title="Item"
icon={Icon.Document}
actions={
<ActionPanel>
<Action
icon={Icon.Eye}
title="View"
onAction={() => console.log("viewed")}
/>
</ActionPanel>
}
/>
</List>
);
}
```
All actions must have an `icon` prop.
## No-View Commands (src/action.ts)
```typescript
import { showToast } from "@vicinae/api";
export default async function QuickAction() {
await showToast({ title: "Done!" });
}
```
## Development Workflow
```bash
npm run build # Production build
npx tsc --noEmit # Type check
# Run dev server in tmux (creates session only if it doesn't exist)
tmux has -t vicinae-dev || tmux new-session -d -s vicinae-dev 'bunx vici develop'
tmux capture-pane -t vicinae-dev -p -S - # Read logs
```
## Navigation & Preferences
Navigate between views with `useNavigation`:
```tsx
const { push, pop } = useNavigation();
<Action icon={Icon.Eye} title="View" onAction={() => push(<DetailView />)} />;
```
Define preferences in the manifest and access with `getPreferenceValues()`.

IncludedLightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.
tanstack-query
IncludedManage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
