Raycast Automator

Build Raycast extensions and script commands from natural language task descriptions. Handles the full lifecycle: analysis, code generation, setup, and dev launch.

Output Directory

All output goes to ~/Documents/raycast-scripts/:

• Script commands: files directly in the root (e.g., my-script.sh)
• Extensions: subdirectories (e.g., my-extension/src/index.tsx)

Create the directory if it doesn't exist. For extensions, create the subdirectory named after the extension.

Decision Flow

User describes a task
  │
  ├─ Analyze complexity
  │   ├─ Needs rich UI (lists, forms, grids, detail views)?  → Extension
  │   ├─ Needs OAuth or token management?                     → Extension
  │   ├─ Needs persistent state across runs?                  → Extension
  │   ├─ Needs menu bar presence?                             → Extension
  │   ├─ Needs pagination or streaming data?                  → Extension
  │   ├─ Simple system operation (open, toggle, copy)?        → Script Command
  │   ├─ Opens URL or does clipboard work?                    → Script Command
  │   ├─ Runs a shell command or API call with simple output? → Script Command
  │   └─ 1-3 simple text inputs, no interactive UI?           → Script Command
  │
  ├─ Present recommendation with reasoning to user
  ├─ User confirms or overrides
  │
  ├─ IF Script Command:
  │   ├─ Pick language:
  │   │   ├─ macOS + simple task       → Bash
  │   │   ├─ Windows + simple task     → Batch/PowerShell
  │   │   ├─ Complex logic / API calls → Python
  │   │   └─ Mac-native automation     → AppleScript
  │   ├─ Generate script with full metadata block
  │   ├─ chmod +x the file
  │   ├─ Ensure ~/Documents/raycast-scripts/ is created
  │   └─ Tell user to add script directory in Raycast if first time
  │
  └─ IF Extension:
      ├─ Scaffold project structure
      ├─ Generate package.json with full manifest
      ├─ Generate src/ entry point(s)
      ├─ Run npm install
      ├─ Run npm run dev
      └─ Confirm extension appears in Raycast

Before Writing Code

1. Read the reference files in reference/ directory of this skill:

   • reference/extension-api.md - for extensions (manifest, UI components, hooks, APIs)
   • reference/script-commands.md - for script commands (metadata, templates, examples)
   • reference/patterns.md - for best practices and common patterns

2. Check platform: Use uname to detect macOS vs other. This affects:

   • Script language defaults (bash vs bat)
   • Available APIs (MenuBarExtra, BrowserExtension are macOS-only)
   • AppleScript availability

Script Command Generation

Required metadata block (ALWAYS include all of these):

#!/bin/bash

# Required parameters:
# @raycast.schemaVersion 1
# @raycast.title <Title Case Name>
# @raycast.mode <silent|compact|fullOutput|inline>

# Optional parameters:
# @raycast.packageName <Category>
# @raycast.icon <emoji or path>
# @raycast.description <What it does>
# @raycast.needsConfirmation <true for destructive ops>
# @raycast.argument1 { "type": "text", "placeholder": "..." }

Mode selection:

Mode	When to use
silent	Opens URL, clipboard ops, launches app, background task
compact	Short confirmation message, quick status
fullOutput	Multi-line output, formatted results, logs
inline	Live status display (requires refreshTime, min 10s)

Language shebangs:

Language	Shebang	Extension
Bash	#!/bin/bash	.sh
Python 3	#!/usr/bin/env python3	.py
Node.js	#!/usr/bin/env node	.js
AppleScript	#!/usr/bin/osascript	.applescript
Ruby	#!/usr/bin/env ruby	.rb
Swift	#!/usr/bin/swift	.swift

Argument access by language:

Language	Arg 1	Arg 2	Arg 3
Bash	$1	$2	$3
Python	sys.argv[1]	sys.argv[2]	sys.argv[3]
Node.js	process.argv[2]	process.argv[3]	process.argv[4]
AppleScript	item 1 of argv	item 2 of argv	item 3 of argv
Ruby	ARGV[0]	ARGV[1]	ARGV[2]
Swift	CommandLine.arguments[1]	CommandLine.arguments[2]	CommandLine.arguments[3]

Script rules:

• Max 3 arguments per script
• Use percentEncoded: true for URL arguments
• Use needsConfirmation: true for destructive operations
• Non-zero exit code = failure (last line becomes error message)
• Scripts run in non-login shell; use #!/bin/bash -l if login shell needed
• inline mode REQUIRES refreshTime (min 10s)
• Use absolute paths since PATH may differ from user's shell

Extension Generation

Minimum project structure:

extension-name/
├── package.json          # Manifest (see reference/extension-api.md)
├── tsconfig.json         # TypeScript config
├── src/
│   └── index.tsx         # Main command entry point
└── assets/
    └── icon.png          # 512x512 PNG (or use command-icon.png)

package.json template:

{
  "$schema": "https://www.raycast.com/schemas/extension.json",
  "name": "extension-name",
  "title": "Extension Title",
  "description": "What it does",
  "icon": "command-icon.png",
  "author": "author-name",
  "categories": ["Productivity"],
  "license": "MIT",

  ],
  "dependencies": {

    "prepublishOnly": "echo \"Error: no publish script\" && exit 1",
    "publish": "npx @raycast/api@latest publish"
  }
}

tsconfig.json template:

{
  "$schema": "https://json.schemastore.org/tsconfig",
  "compilerOptions": {
    "lib": ["ES2023"],
    "module": "Node16",
    "moduleResolution": "node16",
    "target": "ES2022",
    "resolveJsonModule": true,
    "strict": true,
    "jsx": "react-jsx"
  },
  "include": ["src/**/*", "env.d.ts", "raycast-env.d.ts"]
}

Command modes:

Mode	Export	Use case
view	React component (default export)	Interactive UI with List/Detail/Form/Grid
no-view	Async function (default export)	Background tasks, clipboard ops, no UI
menu-bar	MenuBarExtra component	Persistent menu bar item (macOS only)

Choosing the right UI component:

Component	When to use
List	Searchable items, most common. Use isShowingDetail for split view
Detail	Single item display with markdown + metadata sidebar
Form	User input collection. Use useForm hook for validation
Grid	Image-heavy content (icons, thumbnails, galleries)
MenuBarExtra	Always-visible menu bar status/actions

Essential hooks (from @raycast/utils):

Hook	When to use
useFetch	HTTP requests with caching
usePromise	Any async operation
useCachedPromise	Async with stale-while-revalidate caching
useExec	Shell command execution
useForm	Form state + validation
useLocalStorage	Persistent key-value state
useCachedState	State that persists across command runs
useAI	Raycast AI integration (requires Pro)
useSQL	SQLite database queries

Extension rules:

• Always set isLoading prop on top-level components during async ops
• Use showToast(Toast.Style.Failure) for errors, not console.error
• Use showFailureToast from @raycast/utils for standardized errors
• First action in ActionPanel = primary (Enter key)
• Use Action.Push for navigation, not imperative useNavigation
• Use List.EmptyView / Grid.EmptyView for zero-state
• Validate forms on onBlur, clear errors on onChange
• Don't use filtering={true} when you have onSearchTextChange
• Use environment.canAccess() before using Pro features (AI, WindowManagement)

After Generation

For script commands:

1. Create the file in ~/Documents/raycast-scripts/
2. Run chmod +x on the file
3. Tell the user:
   • "Open Raycast Preferences > Extensions > + > Add Script Directory"
   • Point to ~/Documents/raycast-scripts/
   • "You only need to do this once"
4. The command will appear in Raycast search by its @raycast.title

For extensions:

1. Create the project in ~/Documents/raycast-scripts/<extension-name>/
2. Run npm install in the project directory
3. Run npm run dev to start dev mode
4. Tell the user:
   • The extension appears at the top of Raycast search in dev mode
   • Hot reload is active (saves auto-refresh)
   • Stop dev with Ctrl+C in terminal
   • To publish: npm run publish

Icon Guidance

• Script commands: use emoji (simplest) or 64px PNG
• Extensions: need 512x512 PNG. Generate at https://icon.ray.so or use a placeholder
• Support dark mode variant with [email protected] suffix
• For extensions, always include a command-icon.png in assets/ as fallback

Categories (for extensions)

Use exactly one of: Applications, Communication, Data, Design Tools, Developer Tools, Documentation, Finance, Fun, Media, News, Other, Productivity, Security, System, Web

Common Patterns Quick Reference

Fetch + List pattern (most common extension):

import { List } from "@raycast/api";
import { useFetch } from "@raycast/utils";

export default function Command() {
  const { data, isLoading } = useFetch<Result[]>("https://api.example.com/items");
  return (
    <List isLoading={isLoading}>
      {data?.map((item) => (
        <List.Item key={item.id} title={item.name} />
      ))}
    </List>
  );
}

No-view command pattern:

import { showToast, Toast, Clipboard } from "@raycast/api";

export default async function Command() {
  const text = await Clipboard.readText();
  if (!text) {
    await showToast(Toast.Style.Failure, "Clipboard is empty");
    return;
  }
  const result = transform(text);
  await Clipboard.copy(result);
  await showToast(Toast.Style.Success, "Copied to clipboard");
}

Form + submission pattern:

import { Form, ActionPanel, Action, showToast, Toast } from "@raycast/api";
import { useForm, FormValidation } from "@raycast/utils";

interface FormValues {
  name: string;
  description: string;
}

export default function Command() {
  const { handleSubmit, itemProps } = useForm<FormValues>({
    onSubmit(values) {
      showToast(Toast.Style.Success, "Submitted", values.name);
    },
    validation: {
      name: FormValidation.Required,
    },
  });
  return (
    <Form actions={<ActionPanel><Action.SubmitForm onSubmit={handleSubmit} /></ActionPanel>}>
      <Form.TextField title="Name" placeholder="Enter name" {...itemProps.name} />
      <Form.TextArea title="Description" placeholder="Enter description" {...itemProps.description} />
    </Form>
  );
}

Script command - open URL with argument:

#!/bin/bash

# @raycast.schemaVersion 1
# @raycast.title Search Google
# @raycast.mode silent
# @raycast.icon 🔍
# @raycast.packageName Web Searches
# @raycast.argument1 { "type": "text", "placeholder": "query", "percentEncoded": true }

open "https://www.google.com/search?q=$1"
