Gmail

Purpose

Operate Gmail through the connected integration: search and list messages, fetch full bodies, send mail, and inspect labels—without fabricating message content or send confirmations.

When to Use

• List or search messages (unread, from, subject, label filters).
• Read full email content after listing by message ID.
• Send email with to/subject/body (and cc/bcc when specified).
• List labels or check the connected profile.

When NOT to Use

• Calendar, Drive, Docs, or Sheets tasks → google-calendar, google-drive, google-docs, google-sheets.
• Skill authoring or publishing in this repo → create-skill / publish-skill.
• Gmail is not connected or tools are unavailable.

Expected Outcome

• Tool-backed results: subjects, snippets, IDs, send confirmations from API responses.
• List-then-get pattern when full bodies are needed.
• Explicit errors for auth, quota, or missing message IDs.

Inputs to Gather

• Search intent: q string (e.g. is:unread, from:user@example.com, subject:meeting) and/or labelIds.
• Message IDs from a prior list when fetching full content.
• Send payload: to, subject, body; cc/bcc only if the user specified them.

Workflow

1. Confirm Gmail tools are available; do not invent messages or send status.
2. Search/list first: gmail_list_messages with q and/or labelIds, maxResults as needed.
3. Get full body when needed: gmail_get_message with messageId from the list.
4. Send: gmail_send_email with required to, subject, body; add cc/bcc when specified.
5. Summarize results (subject, from, snippet or body excerpt); offer to open specific messages.

Domain rules

1. Search with q: Gmail search syntax in q (e.g. is:unread); use labelIds for INBOX, UNREAD, etc.
2. One list, then get: Prefer filtered list before per-message gets.
3. Send with required fields: Never omit to, subject, or body unless the tool schema allows defaults.

Main tools

• gmail_list_messages (q, labelIds, maxResults), gmail_get_message
• gmail_send_email (to, subject, body), gmail_get_profile, gmail_list_labels

Examples

Unread inbox: gmail_list_messages with q: "is:unread". Return subject, from, snippet; offer gmail_get_message for one thread.

Send: gmail_send_email with user-provided to, subject, body; confirm from tool response only.

Tool Availability Rules

Related tool sets

• email

Review / Decision / Execution Criteria

• Use Gmail q syntax correctly; paginate when result sets are large.
• Do not expose full PII unnecessarily in summaries.
• Confirm before bulk send or destructive label changes if supported.

Output Format

1. Request and actions taken.
2. Message list or send confirmation (from tool output).
3. Errors or missing permissions.
4. Optional next steps (open message, refine search).

Quality Bar

• Grounded in tool responses; cite message IDs when relevant.
• Concise tables or bullets for multiple messages.

Safety and Boundaries

• No secrets or tokens in skill examples or logs.
• Do not fabricate send success.
• Confirm unusual bulk operations with the user.

Escalation / Dispatch Rules

• Cross-product Google work → route to the matching Google skill after resolving file IDs in Drive if needed.
• No write access → provide exact tool arguments for dispatch.
