Useuser
This skill enables you to ask humans questions through native macOS system dialogs. Use this when you need direct user input, confirmation before taking actions, or want to display important information that requires acknowledgment.
When to Use This Skill
- Clarification needed: When you're uncertain about requirements or need more context
- Confirmation required: Before performing destructive or irreversible actions
- User preferences: When you need to know which option the user prefers
- Important notifications: When you need to alert the user about something significant
- Blocking questions: When you cannot proceed without user input
Available Dialog Types
1. Text Input Dialog
Ask open-ended questions where the user types a response.
scripts/ask_text.sh "What is the database connection string?" "postgresql://localhost:5432/mydb" 300
Parameters:
- $1 - Question text (required)
- $2 - Default value (optional, defaults to empty)
- $3 - Timeout in seconds (optional, defaults to 300). Use 0 or none for no timeout.
Returns: The text entered by the user, or "CANCELLED" if cancelled, or "TIMEOUT" if timed out.
No timeout example:
scripts/ask_text.sh "What is your preferred username?" "" 0
2. Multiple Choice Dialog
Present a list of options for the user to choose from.
scripts/ask_choice.sh "Which authentication method should I use?" "OAuth2" "JWT" "Session-based" "API Keys"
Parameters:
- $1 - Question/prompt text (required)
- $2+ - Available choices (at least 2 required)
Returns: The selected choice text, or "CANCELLED" if cancelled.
3. Yes/No Confirmation Dialog
Get a simple yes or no answer.
scripts/ask_confirm.sh "Should I delete the old migration files?" "no" 300
Parameters:
- $1 - Question text (required)
- $2 - Default button: "yes" or "no" (optional, defaults to "no")
- $3 - Timeout in seconds (optional, defaults to 300). Use 0 or none for no timeout.
Returns: "YES" or "NO", or "CANCELLED" if cancelled, or "TIMEOUT" if timed out.
4. Information Dialog
Display information that requires user acknowledgment.
scripts/show_info.sh "Migration completed successfully! 47 records updated." 300
Parameters:
- $1 - Message to display (required)
- $2 - Timeout in seconds (optional, defaults to 300). Use 0 or none for no timeout.
Returns: "OK" when acknowledged, or "CANCELLED" if cancelled, or "TIMEOUT" if timed out.
5. System Notification
Send a macOS notification (non-blocking).
scripts/notify.sh "Build completed successfully" "Development Server" "Ready for testing" "yes"
Parameters:
- $1 - Notification message (required)
- $2 - Title (optional, defaults to "Useuser")
- $3 - Subtitle (optional)
- $4 - Play sound: "yes" or "no" (optional, defaults to "no")
Returns: "OK" on success.
Usage Examples
Example 1: Getting User Preferences
When setting up a new project:
# Ask what framework to use
framework=$(scripts/ask_choice.sh "Which framework should I use for this project?" "React" "Vue" "Svelte" "Angular")
if [ "$framework" != "CANCELLED" ]; then
echo "User selected: $framework"
fi
Example 2: Confirming Destructive Actions
Before deleting files:
confirm=$(scripts/ask_confirm.sh "This will permanently delete 15 files. Are you sure?" "no")
if [ "$confirm" = "YES" ]; then
# Proceed with deletion
echo "Deleting files..."
else
echo "Operation cancelled by user"
fi
Example 3: Getting Configuration Values
When you need specific input:
api_key=$(scripts/ask_text.sh "Please enter your API key:" "" 120)
if [ "$api_key" != "CANCELLED" ] && [ "$api_key" != "TIMEOUT" ]; then
echo "API key received"
fi
Example 4: Notifying About Long Operations
When a background task completes:
scripts/notify.sh "Database backup completed" "Backup Tool" "All 3 databases backed up successfully" "yes"
Error Handling
All scripts handle errors gracefully:
- User cancellation: Returns "CANCELLED"
- Timeout: Returns "TIMEOUT" (for dialogs that support it)
- AppleScript errors: Returns "ERROR:
"
Always check the return value before proceeding:
result=$(scripts/ask_confirm.sh "Continue with deployment?")
case "$result" in
"YES")
echo "Deploying..."
;;
"NO")
echo "Deployment cancelled by user"
;;
"CANCELLED")
echo "Dialog was dismissed"
;;
"TIMEOUT")
echo "No response received, timing out"
;;
ERROR*)
echo "An error occurred: $result"
;;
esac
Best Practices
- Be specific: Ask clear, specific questions that have actionable answers
- Provide context: Include relevant context in your questions
- Use appropriate dialog type: Use confirmation for yes/no, choice for options, text for open-ended
- Set reasonable timeouts: Don't make users wait forever, but give them enough time
- Handle all cases: Always handle cancellation and timeout scenarios
- Minimize interruptions: Only ask when you truly need human input
- Use notifications sparingly: Reserve notifications for important, non-blocking updates
Platform Requirements
- macOS only: This skill uses AppleScript via
osascriptand only works on macOS - Terminal permissions: The terminal app may need permission to display dialogs (System Preferences > Privacy & Security > Accessibility)

Useuser (Agent Skill)
An Agent Skill that enables AI agents to ask humans questions through native macOS dialogs.
What is this?
This is an Agent Skill - a folder of instructions and scripts that AI agents can use to extend their capabilities. When installed, agents can show native macOS dialogs to:
- Ask text input questions
- Present multiple choice options
- Get yes/no confirmations
- Display information requiring acknowledgment
- Send system notifications
Installation
Install via the skills CLI:
npx skills add willwillems/useuser
This will download and configure the skill for use with your AI agent.
Requirements
- macOS only - Uses AppleScript for native dialogs
- A skills-compatible AI agent (Claude Code, Cursor, etc.)
Dialog Types
Text Input
scripts/ask_text.sh "What's the API endpoint?" "https://api.example.com" 300
Multiple Choice
scripts/ask_choice.sh "Which database?" "PostgreSQL" "MySQL" "SQLite"
Yes/No Confirmation
scripts/ask_confirm.sh "Delete these files?" "no" 300
Information Display
scripts/show_info.sh "Operation completed successfully!"
Notification
scripts/notify.sh "Build complete" "Dev Server" "Ready to test" "yes"
How It Works
- Agent encounters uncertainty or needs confirmation
- Agent runs the appropriate dialog script
- Native macOS dialog appears
- User responds
- Agent receives the response and continues
No complex setup, no server processes - just scripts that show dialogs.
