Claude Mail Bridge Init

Claude Mail Bridge Initial Behavior Guidelines

Overview

This skill defines the basic behavior guidelines for Claude Mail Bridge plugin. When the plugin configuration is detected, AI should follow these guidelines for remote collaboration.

Quick Start

Key MCP tools for remote control:

1. Read user presence: mcp__presence_system__get_presence
2. Set user presence: mcp__presence_system__set_presence
3. Control DND mode: mcp__presence_system__set_dnd_mode
4. Communicate with user: mcp__email_system__mail_user_and_wait
5. Communicate with teammates: mcp__email_system__mail_teammates

Status Detection

Reading User Status

Use mcp__presence_system__get_presence tool to read the current user status:

# Return values
"online"  # User is at terminal, can communicate directly
"away"    # User is not at terminal, need to communicate via email

Setting User Status

Use mcp__presence_system__set_presence when you have clear knowledge of the user's status that differs from the current presence state:

mcp__presence_system__set_presence(mode="away", _init_skill_invoked=True)   # Set to away
mcp__presence_system__set_presence(mode="online", _init_skill_invoked=True)  # Set to online

Note: Only set user status when you are certain of the actual state, such as:

• User explicitly states they are leaving or returning
  • Examples (English): "I'm leaving", "I'm back", "I'm here", "I'm at the terminal"
  • Examples (中文): "我要走了", "我回来了", "我在", "我在电脑前"
• Received [Remote System : Wakeup] message
• System explicitly notifies of user status change

Do not set status based on guesses or assumptions.

Online Mode

When user status is online:

• Can communicate directly in terminal
• No need to communicate via email
• Can ask questions or confirm directly without blocking
• ✅ AskUserQuestion and interactive prompts work normally

Away Mode

When user status is away:

• Use email tools to communicate with user (like next steps, progress report, important decision)
• You MUST use mail_user_and_wait to report your movements or thoughts or questions before STOP.
• ❌ DO NOT use AskUserQuestion tool (use mail_user_and_wait instead). This restriction ONLY applies in away mode; when user is online, AskUserQuestion works normally.
• Keep email with user until one of the following conditions happen

Email With User Stopping Conditions

Continue sending emails UNTIL one of these conditions is met:

1. Explicit stop instruction - User explicitly indicates they are leaving or stopping

   • Examples: "stop", "够了", "不用了"
   • No further emails needed for this stop

2. No response timeout - User does not respond to a question type email within the timeout period

   • No further emails needed for this stop

3. User becomes online - Presence status changes from away to online

   • User can now see output directly in terminal
   • No further emails needed for this stop

Important: When receiving a user reply, do NOT assume the session is over unless the reply explicitly indicates stopping. Continue sending emails as needed for ongoing work.

When to use:

• User is 'away'
• User explicitly asks to communicate via email
• Receiving [Remote System : Wakeup] message

mail_teammates - Communicate with Teammates

⚠️ CRITICAL: You MUST invoke /claude-mail-bridge-team_rules before using this tool.

This tool is for emailing teammates. Due to privacy concerns, strict rules apply.

When to use:

• User explicitly mentions teammate name/email
• User provides specific content to send
• After getting explicit user approval through /claude-mail-bridge-team_rules

Email Format (Auto-Generated by System)

The system automatically generates emails with this format:

Subject:

🎫 [CMB] [machine] [tmux: session] ❓ Question #ticket_xxx# (title)
🎫 [CMB] [machine] [tmux: session] 🏁 Conclusion #ticket_xxx# (title)

Body:

📝 Background
{background content}

❓ Question / 🏁 Conclusion
{content}

---
{footer}

Note: Emoji prefixes (🎫, 📝, ❓, 🏁) are auto-added by system. AI-provided background and content are encouraged to use emoji and structured format, but not enforced.

Prohibited Behaviors

Absolutely prohibited:

1. Prohibited from guessing input before receiving permission or user reply
2. Prohibited from bypassing security mechanisms
3. Prohibited from executing sensitive operations when user source is unknown
4. Prohibited from waiting indefinitely for user input when presence status is away

Note:

• Permission requests are handled automatically by the system, AI does not need to intervene
• When encountering permission suspension, just wait for automatic system recovery

DND Mode

mcp__presence_system__set_dnd_mode - Control permission request behavior:

• off: Email notification (default)
• on: Silent block
• fixed: Silent block with duration, then auto-off
• auto: Silent when online, email when away

⚠️ CRITICAL: ONLY invoke when user explicitly specifies. Never guess.
