Textme

iMessage Skill

Description

Send and receive iMessages via Claude Code. Get real-time input from the user via their phone, similar to how call-me enables voice conversations.

When to Use This Skill

Use ask_user when:

• You've completed significant work and want to report status and ask what's next
• You need real-time input for decisions
• You're blocked and need clarification to proceed
• You want to discuss next steps with the user

Use notify_user when:

• You want to send a status update without needing a response
• The information is non-urgent
• You don't want to block waiting for a reply

Do NOT use for:

• Simple yes/no questions that can be asked in the terminal
• Information the user has already provided
• Sending to non-whitelisted numbers

Primary Tools

ask_user

Send an iMessage and wait for the user to respond. This is the main tool - similar to initiate_call in call-me.

Parameters:

• message (string, required): What to ask the user. Be conversational.
• timeout_seconds (number, optional): How long to wait (default: 300 = 5 minutes)

Behavior:

1. Sends iMessage to the user
2. Waits for response (polls every 5 seconds)
3. Returns the user's response when received
4. If timeout: returns notice, response will be picked up later via check_messages

Example:

ask_user({ message: "Finished the auth module. Should I work on API endpoints or tests next?" })
→ User responds via phone: "API endpoints"
→ Returns: "User responded: API endpoints"
→ Claude continues working on API endpoints

notify_user

Send an iMessage without waiting for a response. Fire-and-forget.

Parameters:

• message (string, required): Message to send

Example:

notify_user({ message: "Starting the database migration. This will take about 10 minutes." })
→ Returns immediately: "Notification sent"
→ Claude continues working

Secondary Tools

check_messages

Check for pending iMessages. Use this to pick up responses that arrived after a timeout.

send_message

Send a message to a specific number. Lower-level than notify_user.

get_conversation

Get conversation history with a contact for context.

mark_read

Mark a message as processed without responding.

list_contacts

List all contacts who have messaged.

clear_history

Clear conversation history with a contact.

Example Workflows

Simple question and continue:

Claude: [finishes auth module]
Claude: ask_user("Hey! Finished the auth module. API endpoints or tests next?")
        → sends iMessage, waits...
User:   [responds on phone] "API endpoints please"
Claude: → receives response
Claude: [continues with API endpoints]

Status update (no response needed):

Claude: notify_user("Starting the build process. Will let you know when done.")
Claude: [runs build]
Claude: ask_user("Build complete! 0 errors. Ready to deploy to staging?")
User:   "Yes, deploy it"
Claude: [deploys to staging]

Multi-turn conversation:

Claude: ask_user("I found 3 approaches for the caching layer. Want me to explain them?")
User:   "Yes please"
Claude: ask_user("Option 1: Redis - fast, needs server. Option 2: In-memory - simple, no persistence. Option 3: SQLite - persistent, slower. Which sounds best?")
User:   "Redis"
Claude: [implements Redis caching]

Best Practices

1. Be conversational - Write messages like texts, not documentation
2. Be concise - Phone screens are small
3. Provide context - Explain what you did before asking
4. Offer clear options - "A or B?" is easier than open-ended questions
5. Use notify_user for updates - Don't block when you don't need input
6. Trust the timeout - If no response in 5 min, user is busy - continue or wait

How It Works

• MCP server polls Sendblue every 5 seconds for new messages
• ask_user blocks up to 5 minutes waiting for response
• Only whitelisted phone numbers can send/receive
• Conversation history is maintained for context
• Stop hook evaluates if Claude should proactively message the user
