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 | $0.00020 | $0.02098 |
| Opus 5 | $0.00010 | $0.01049 |
| Sonnet 5 | $0.00004 | $0.00420 |
| Haiku 4.5 | $0.00002 | $0.00210 |
Grade A, and why
analyze-thread 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.
How it starts
The opening of the file, as written. The whole thing — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Analyze Email Thread
Comprehensive analysis of an email thread including conversation flow, participant interactions, timeline, key points, and attachment evolution.
When to Use
Use this skill when you need to:
- Understand complete conversation context
- Track discussion progression over time
- Identify key decisions and action items
- See how attachments evolved through the thread
- Get overview of multi-email conversations
Triggers:
English:
- "Analyze this email thread
<message-id>" - "Show me the conversation
<message-id>" - "What's the thread about
<message-id>" - "Thread analysis for
<message-id>" - "Summarize this thread
<message-id>"
Chinese:
- "分析这个邮件线索
<message-id>" - "看看这个对话
<message-id>" - "整理一下这个线索
<message-id>" - "线索内容总结
<message-id>" - "这个讨论的脉络
<message-id>"
Invocation Methods
Method 1: Natural Language (Recommended)
User: Analyze this email thread <[email protected]>
AI: [Proceeds to analyze immediately]
Method 2: Slash Command
User: /analyze-thread
AI: 请提供线索中任意一封邮件的 Message-ID
User: <[email protected]>
AI: [Proceeds to analyze]
Note: Any message-id from the thread works. The system will find all related emails.
Execution Steps
-
Get message-id (if not provided)
Please provide any Message-ID from the thread 💡 Quick method (recommended): In Mail.app: Select email → Press shortcut (⌘⇧C) → Message-ID copied See README "Setup Mail Quick Action" section if not configured -
Read thread using MCP
thread_data = mcp__mail__read_thread(message_id) -
Handle truncation checks
Check 1: Thread Result Oversized
- If result indicates size overflow (>80KB):
- Warn user about thread size
- Suggest reducing max_body_length
- Ask if user wants to retry with tighter limits
Check 2: Individual Email Truncation
- After successful load, check for truncated emails
- Classify by importance:
- ⚠️ Critical: Truncated + has attachments
- ⚠️ High: Lost 60%+ content
- ℹ️ Medium: Only quote-stripped
- Suggest reading important emails individually if needed
- If result indicates size overflow (>80KB):
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.

analyze-thread is a skill published in the GitHub repository fatbobman/mail-mcp-bridge (19 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 2,098 once invoked, about $0.0001 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 2026-08-30.
