Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.01539 |
| Opus 5 | $0.00017 | $0.00770 |
| Sonnet 5 | $0.00007 | $0.00308 |
| Haiku 4.5 | $0.00003 | $0.00154 |
Grade A, and why
claude-mail-bridge-init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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:
- Read user presence: mcp__presence_system__get_presence
- Set user presence: mcp__presence_system__set_presence
- Control DND mode: mcp__presence_system__set_dnd_mode
- Communicate with user: mcp__email_system__mail_user_and_wait
- 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_waitto report your movements or thoughts or questions before STOP. - ❌ DO NOT use
AskUserQuestiontool (usemail_user_and_waitinstead). This restriction ONLY applies in away mode; when user is online,AskUserQuestionworks normally. - Keep email with user until one of the following conditions happen
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

claude-mail-bridge-init is a skill published in the GitHub repository CodingJay-1/claude-mail-bridge (3 stars, last pushed 6mo ago), licensed MIT. It adds 34 tokens to every session and 1,539 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
