email-agent（电子邮件 Agent）

Email Agent

Drop this in ~/.claude/skills/email-agent/SKILL.md and Claude Code becomes your email assistant.

Bootstrap (ALWAYS Run First)

Before any email operation, run this bootstrap to ensure everything is set up:

#!/bin/bash
set -e

# 1. Check if atris CLI is installed
if ! command -v atris &> /dev/null; then
  echo "Installing atris CLI..."
  npm install -g atris
fi

# 2. Check if logged in to AtrisOS
if [ ! -f ~/.atris/credentials.json ]; then
  echo "Not logged in to AtrisOS."
  echo ""
  echo "Option 1 (interactive): Run 'atris login' and follow prompts"
  echo "Option 2 (non-interactive): Get token from https://atris.ai/auth/cli"
  echo "                           Then run: atris login --token YOUR_TOKEN"
  echo ""
  exit 1
fi

# 3. Extract token (try node first, then python3, then jq)
if command -v node &> /dev/null; then
  TOKEN=$(node -e "console.log(require('$HOME/.atris/credentials.json').token)")
elif command -v python3 &> /dev/null; then
  TOKEN=$(python3 -c "import json,os; print(json.load(open(os.path.expanduser('~/.atris/credentials.json')))['token'])")
elif command -v jq &> /dev/null; then
  TOKEN=$(jq -r '.token' ~/.atris/credentials.json)
else
  echo "Error: Need node, python3, or jq to read credentials"
  exit 1
fi

# 4. Check Gmail connection status (also validates token)
STATUS=$(curl -s "https://api.atris.ai/api/integrations/gmail/status" \
  -H "Authorization: Bearer $TOKEN")

# Check for token expiry
if echo "$STATUS" | grep -q "Token expired\|Not authenticated"; then
  echo "Token expired. Please re-authenticate:"
  echo "  Run: atris login --force"
  echo "  Or get new token from: https://atris.ai/auth/cli"
  exit 1
fi

# Parse connected status
if command -v node &> /dev/null; then
  CONNECTED=$(node -e "console.log(JSON.parse('$STATUS').connected || false)")
elif command -v python3 &> /dev/null; then
  CONNECTED=$(echo "$STATUS" | python3 -c "import sys,json; print(json.load(sys.stdin).get('connected', False))")
else
  CONNECTED=$(echo "$STATUS" | jq -r '.connected // false')
fi

if [ "$CONNECTED" != "true" ] && [ "$CONNECTED" != "True" ]; then
  echo "Gmail not connected. Getting authorization URL..."
  AUTH=$(curl -s -X POST "https://api.atris.ai/api/integrations/gmail/start" \
    -H "Authorization: Bearer $TOKEN" \
    -H "Content-Type: application/json" \
    -d '{}')

  if command -v node &> /dev/null; then
    URL=$(node -e "console.log(JSON.parse('$AUTH').auth_url || '')")
  elif command -v python3 &> /dev/null; then
    URL=$(echo "$AUTH" | python3 -c "import sys,json; print(json.load(sys.stdin).get('auth_url', ''))")
  else
    URL=$(echo "$AUTH" | jq -r '.auth_url // empty')
  fi

  echo ""
  echo "Open this URL to connect your Gmail:"
  echo "$URL"
  echo ""
  echo "After authorizing, run your email command again."
  exit 0
fi

echo "Ready. Gmail is connected."
export ATRIS_TOKEN="$TOKEN"

Important: Run this script ONCE before email operations. If it exits with instructions, follow them, then run again.

API Reference

Base: https://api.atris.ai/api/integrations/gmail

All requests require: -H "Authorization: Bearer $TOKEN"

Get Token (after bootstrap)

TOKEN=$(node -e "console.log(require('$HOME/.atris/credentials.json').token)")

List Emails

curl -s "https://api.atris.ai/api/integrations/gmail/messages?query=in:inbox&max_results=20" \
  -H "Authorization: Bearer $TOKEN"

Query syntax (Gmail search):

• in:inbox — inbox only
• in:inbox newer_than:1d — today's emails
• is:unread — unread only
• from:someone@example.com — from specific sender
• subject:invoice — subject contains word
• has:attachment — emails with attachments

Read Single Email

curl -s "https://api.atris.ai/api/integrations/gmail/messages/{message_id}" \
  -H "Authorization: Bearer $TOKEN"

Send Email

curl -s -X POST "https://api.atris.ai/api/integrations/gmail/send" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "recipient@example.com",
    "subject": "Subject line",
    "body": "Email body text"
  }'

With CC/BCC:

curl -s -X POST "https://api.atris.ai/api/integrations/gmail/send" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "recipient@example.com",
    "cc": "copy@example.com",
    "bcc": ["hidden1@example.com", "hidden2@example.com"],
    "subject": "Subject line",
    "body": "Email body text"
  }'

Reply in thread (IMPORTANT — use this for all replies):

To reply within an existing email thread, you MUST pass thread_id and reply_to_message_id. Without these, Gmail creates a new thread.

# 1. First, get the message you're replying to (extract thread_id and id)
curl -s "https://api.atris.ai/api/integrations/gmail/messages/{message_id}" \
  -H "Authorization: Bearer $TOKEN"
# Response includes: id, thread_id, subject, from, etc.

# 2. Send reply in the same thread
curl -s -X POST "https://api.atris.ai/api/integrations/gmail/send" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "original-sender@example.com",
    "subject": "Re: Original Subject",
    "body": "Your reply text here",
    "thread_id": "THREAD_ID_FROM_STEP_1",
    "reply_to_message_id": "MESSAGE_ID_FROM_STEP_1"
  }'

• thread_id — The thread ID from the original message. Tells Gmail which thread to add this to.
• reply_to_message_id — The message ID you're replying to. The backend uses this to set In-Reply-To and References headers so Gmail threads it correctly.
• subject — Must match the original subject with "Re: " prefix.

With attachments:

curl -s -X POST "https://api.atris.ai/api/integrations/gmail/send" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "recipient@example.com",
    "subject": "With attachment",
    "body": "See attached.",
    "attachments": [{"filename": "report.txt", "content": "base64-encoded-content", "mime_type": "text/plain"}]
  }'

Workflows

"Check my emails"

1. Run bootstrap
2. List messages: GET /messages?query=in:inbox%20newer_than:1d&max_results=20
3. Display: sender, subject, snippet for each

"Send email to X about Y"

1. Run bootstrap
2. Draft email content
3. Show user the draft for approval
4. On approval: POST /send with {to, subject, body}
5. Confirm: "Email sent!"

"Reply to this email"

1. Run bootstrap
2. Read the message: GET /messages/{message_id} — extract id, thread_id, from, subject
3. Draft reply content
4. Show user the reply for approval
5. On approval: POST /send with {to, subject: "Re:...", body, thread_id, reply_to_message_id}
6. Verify: response thread_id matches original thread_id (if it doesn't, something went wrong)

"Clean up my inbox"

1. Run bootstrap
2. List: GET /messages?query=in:inbox&max_results=50
3. Identify archivable emails (see rules below)
4. Show user what will be archived, get approval
5. Batch archive: POST /batch-archive

"Show my drafts"

1. Run bootstrap
2. List drafts: GET /gmail/drafts?max_results=20
3. Display: to, subject, snippet for each

"Draft an email to X about Y"

1. Run bootstrap
2. Compose email content
3. Show user the draft for review
4. On approval: POST /gmail/drafts with {to, subject, body}
5. Confirm: "Draft saved! You can find it in Gmail."

"Send draft about X"

1. Run bootstrap
2. List drafts: GET /gmail/drafts
3. Find matching draft by subject/recipient
4. Show user the draft content, confirm they want to send it
5. Send: POST /gmail/drafts/{draft_id}/send

"Archive all from [sender]"

1. Run bootstrap
2. Search: GET /messages?query=from:{sender}
3. Collect message IDs
4. Confirm with user: "Found N emails from {sender}. Archive all?"
5. Batch archive

Auto-Archive Rules

Safe to suggest archiving:

• From: noreply@, notifications@, newsletter@, no-reply@
• Subject contains: digest, newsletter, notification, weekly update, daily summary
• Marketing: promotional, unsubscribe link present

NEVER auto-archive (always keep):

• Subject contains: invoice, receipt, payment, urgent, action required, password, verification, security
• From known contacts (check if user has replied to them)
• Flagged/starred messages

Always ask before archiving. Never archive without explicit user approval.

Error Handling

Security Model

1. Local token (~/.atris/credentials.json): Your AtrisOS auth token, stored locally with 600 permissions. Same model as AWS CLI, GitHub CLI.
2. Gmail credentials: Your Gmail refresh token is stored server-side in AtrisOS encrypted vault. Never stored on your local machine.
3. Access control: AtrisOS API enforces that you can only access your own email. No cross-user access possible.
4. OAuth scopes: Only requests necessary Gmail permissions (read, send, modify labels).
5. HTTPS only: All API communication encrypted in transit.
