admin_delete_message

Delete any message in a group you administer, regardless of the sender, with immediate removal for all participants.

Instructions

As a group admin, delete any message posted in a group you administer, regardless of who sent it. The message is removed for all participants immediately. Only works if you are an admin of the specified group — use list_groups to confirm admin status. For deleting your own messages use delete_message (DM) or delete_group_message (group) instead.

Behavior4/5

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

No annotations provided, but description covers key behaviors: immediate removal for all participants, admin-only requirement. Could mention irreversibility, but sufficient.

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 concise sentences with front-loaded verb. Every sentence adds value, no redundancy.

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?

No output schema, but for a delete action the description covers prerequisites, effect, and alternatives. Complete for tool's complexity.

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

Parameters4/5

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

Schema coverage 100% with basic descriptions. Description adds context by specifying sources for each parameter (list_groups, phone number, get_conversation), which aids usage.

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?

Description clearly states the tool deletes any message in a group as an admin, regardless of sender. It distinguishes from siblings like delete_message and delete_group_message.

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

Usage Guidelines5/5

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

Explicitly states when to use (as admin deleting any message) and when not (own messages use other tools). Provides prerequisite: confirm admin status with list_groups.

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