Delete Group

wa_delete_group

Destructive

Delete a WhatsApp group: remove every other member and then leave. The account must be a group admin. WhatsApp has no true group-delete, so this empties the group and exits it.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`group_jid`	Yes	the group (…@g.us) JID to delete, as returned by wa_list_groups
`account_id`	Yes	the account, as returned by wa_list_accounts

Output Schema

TableJSON Schema

Name	Required	Description
`items`	No	the rows of a list operation
`status`	Yes	ok (the operation succeeded) or refused (see refusal; for wa_update_group, applied lists the changes that took effect before it)
`applied`	No	wa_update_group only: the settings that were changed, in order — on a refusal, the ones that took effect before it
`refusal`	No	present only when status is refused
`summary`	No	a human-readable result
`group_jid`	No	the new group's JID (wa_create_group only) — use it as wa_send_message's 'to'
`invite_link`	No	the group's invite link (wa_create_group or wa_get_group_invite_link)

A4.5/5.0

Behavior5/5

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

Annotations already declare destructiveHint=true and readOnlyHint=false, but the description adds the two things an agent most needs: the side effect in full ('remove every other member and then leave') and the authorization requirement (admin). It also explains that no true delete exists, so the semantics are genuinely different from what the name implies.

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?

Three short sentences, zero filler, with the destructive effect front-loaded ahead of the caveat about WhatsApp having no true delete. Every sentence carries distinct information.

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

Completeness5/5

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

An output schema exists, so return values need no explanation. With annotations covering safety/non-idempotency and the description covering the real side effect and admin prerequisite, an agent has everything needed to decide and invoke correctly.

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% and both parameters already document their format and how to obtain the values (from wa_list_groups / wa_list_accounts). The description adds no parameter-level detail, so this sits at the baseline.

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 and resource ('Delete a WhatsApp group') and immediately defines what that operation actually means in this domain: remove every other member, then leave. This distinguishes it cleanly from siblings like wa_leave_chat and wa_remove_participants, which an agent could otherwise confuse it with.

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?

Gives a concrete precondition ('The account must be a group admin'), which is the key gate for calling it correctly. It does not explicitly name an alternative tool or say when not to use it (e.g., 'to only leave without deleting, use wa_leave_chat'), so it stops short of full when/when-not routing.

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