delete_group

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

The annotations already signal destructive and idempotent behavior, and the description adds valuable nuance: the operation does not delete videos, only their membership. This clarifies the practical impact of the delete beyond what the annotation flags provide.

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

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

The description is a single sentence that front-loads the core action and follows with the key exception. Every word contributes to understanding the operation.

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

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

For a simple destructive tool with an output schema and two parameters, the description covers the critical behavioral nuance and leaves the required identifier self-evident from the schema. It is slightly incomplete around the optional rationale semantics, but not enough to hinder correct invocation.

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

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

Schema description coverage is 0%, and the description provides no details about group_id or rationale. The required group_id is inferable from its name, but the optional rationale parameter is left completely unexplained, so the description does not compensate for the missing parameter documentation.

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

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

The description opens with the specific action and object, 'Delete a video group,' which clearly differentiates this from sibling video operations like delete_video. The follow-up clarification that videos in the group are not deleted removes ambiguity about what the tool targets.

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

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

The explanation that videos are simply removed from the group gives an agent clear context to choose this tool when the intent is to delete the group but preserve its videos. It does not explicitly name an alternative such as delete_video, so it stops short of full when-not guidance.

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