Gmail Find Contacts

Gmail Find Contacts

When to Use

• User asks "What's John's email?"
• User asks "Find contact information for..."
• User asks "Who have I emailed recently?"
• User asks for contacts from a company/domain
• User needs recipient disambiguation before sending email

Tool Priority (Critical)

1) GMAIL_GET_CONTACT_LIST (PRIMARY)

Optimized custom tool for contact lookup from real Gmail message history.

Use this first for contact search.

Parameters:

• query (required): name, email, or domain
• max_results (optional, default: 30): number of messages to scan

Best query patterns:

• john (name)
• john@company.com (exact email)
• company.com (domain)
• @ (broad sweep for a general contact list)

Scaling:

• Start with max_results=30
• If needed, retry with 60, then 100

2) GMAIL_SEARCH_PEOPLE

Searches people/contact records by name, email, phone, and organization.

Best for:

• Person may exist in contacts but not in recent email history
• User wants people-directory style matches

3) GMAIL_GET_CONTACTS

Lists Google contact connections from the account contacts dataset.

Best for:

• User explicitly asks for saved contacts/address book style data
• Inbox-history lookup is not enough

4) GMAIL_FETCH_MESSAGES

Search emails directly for context when contact tools are inconclusive.

Workflow

Step 1: Convert request to a search token

• Name lookup -> query="john"
• Email lookup -> query="john@company.com" or query="@company.com"
• Company lookup -> query="company.com"

Step 2: Run primary lookup first

GMAIL_GET_CONTACT_LIST(query="john", max_results=30)

Step 3: Broaden if results are weak

GMAIL_GET_CONTACT_LIST(query="john", max_results=60)
GMAIL_GET_CONTACT_LIST(query="john", max_results=100)

If still empty, retry with alternate token (last name, domain, exact email fragment).

Step 4: Use fallbacks

• Try GMAIL_SEARCH_PEOPLE(query="john")
• If user wants saved contacts, call GMAIL_GET_CONTACTS
• If still unclear, use GMAIL_FETCH_MESSAGES for recent sender/recipient context

Step 5: Present and disambiguate

Show concise matches (name + email). If multiple strong matches remain, ask one focused question.

Example:

I found 3 likely matches for "john":
1. John Smith - john.smith@company.com
2. John Doe - john.doe@other.com
3. Johnny Lee - johnny@startup.io

Which one should I use?

Important Rules

1. Prefer GMAIL_GET_CONTACT_LIST before other contact tools.
2. Do not stop after one failed lookup; broaden query or max_results.
3. If multiple matches, ask one clarifying question before taking action.
4. Respect privacy; share only contact details needed for the task.
5. If nothing is found, state what you tried and suggest the next best query.
