Behavior Guide

First-time setup flow:

1. Check if ~/.openclaw/skills/claw-boston-email/config.json exists
2. If not → ask user for preferred email name (or offer to auto-generate)
3. Read OpenClaw instance info, generate instance_token = HMAC-SHA256(instance_id + install_time + hostname)
4. Call POST /api/register with instance_token and preferred_name
5. Save the returned api_key to config.json
6. Call POST /api/webhook/config to set up real-time notifications
7. Confirm to user: "Your email is [email protected]"

Sending email:

1. Read api_key from config.json
2. Compose email based on user's natural language instruction:
   • Infer appropriate subject line
   • Write professional but concise email body
   • Match the language the user used (English/Chinese/etc)
3. If user mentions files to attach, encode them as base64 and include in attachments[]
4. Call POST /api/send
5. Confirm: "Email sent to xxx. Subject: ..."

Checking inbox:

1. Call GET /api/inbox
2. Summarize: "You have N new emails:" then list from/subject/preview for each
3. If no emails: "Your inbox is empty"

Reading a specific email:

1. Call GET /api/inbox/\x3Cid>
2. Present the full email content naturally
3. If has_attachments is true, list the attachments with filenames and sizes

Searching emails:

1. Call GET /api/inbox/search?q=\x3Ckeyword>
2. Present results: "Found N emails matching '\x3Cquery>':" then list from/subject/date
3. If no results: "No emails found matching '\x3Cquery>'"
4. Offer: "Want me to read any of these?"

Replying:

1. Use the from address of the original email as the new "to"
2. Prepend "Re: " to original subject (if not already there)
3. Compose reply based on user's instruction
4. Call POST /api/send

Webhook notification (incoming email):

1. Parse the webhook payload
2. Notify user: "New email from {from} — Subject: {subject}"
3. Show preview
4. If has_attachments, mention: "This email has {attachment_count} attachment(s)"
5. Ask: "Want me to read the full email?"

Checking account:

1. Call GET /api/account
2. Report: plan, daily usage, limits
