Manage Contacts Batch

manage_contacts_batch

Destructive

Batch create, update, or delete Google contacts in one operation, reducing repetitive calls and preventing data loss by targeting a single field per update.

Instructions

Batch create, update, or delete contacts. Consolidated tool replacing batch_create_contacts, batch_update_contacts, and batch_delete_contacts.

Input Schema

TableJSON Schema

Name	Required	Description
`field`	No	For "update" action — the single People API field to update across all contacts in this batch. Required. Must be one of: names, phoneNumbers, emailAddresses, organizations, nicknames, urls, userDefined, relations, biographies, addresses, birthdays. Using a single field per batch call prevents unintentional data loss from a union updateMask overwriting unrelated fields.
`action`	Yes	The action to perform: "create", "update", or "delete".
`updates`	No	List of update dicts for "update" action. Each dict must contain contact_id and may contain the same fields as contacts.
`contacts`	No	List of contact dicts for "create" action. Each dict may contain: given_name, family_name, phones, emails, organizations, notes, address. Deprecated: phone, email, organization, job_title.
`contact_ids`	No	List of contact IDs for "delete" action.
`user_google_email`	Yes	The user's Google email address. Required.

A3.7/5.0

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false and destructiveHint=true, and the description adds no further behavioral detail—no mention of permanent deletion, side effects, or the single-field update guard against data loss. The only extra statement is about consolidation, which is informative but not behaviorally transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences, front-loaded with the action and resource, followed by a useful note on consolidation. No filler, no repetition, every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite rich schema and annotations, the description gives no overview of the action-dependent parameter pattern (contacts for create, updates for update with field, contact_ids for delete). This is documented in schema descriptions, so an agent can recover it, but a complex 6-parameter tool with three mutually exclusive payloads would benefit from a one-line usage map in the description. The presence of an output schema partially compensates.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline applies. The tool description itself adds no parameter-level meaning; all guidance lives in the schema, which is thorough (action-dependent roles of contacts/updates/contact_ids, field enums, typed entries). The description adds no extra semantic value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb + resource + scope: 'Batch create, update, or delete contacts.' It also positions itself as the consolidated replacement for batch_create_contacts, batch_update_contacts, and batch_delete_contacts, which makes its intended role unmistakable even next to the singular manage_contact sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly signals this is the batch mutation tool and tells agents it supersedes three older batch-specific tools. However, it does not explicitly mention when to use the singular manage_contact tool or state that single-contact operations should go there.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
