apple_delete_subscription_group

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

With no annotations provided, the brief description carries the full burden of behavioral disclosure. It indicates destruction (delete) but omits critical details such as permanence, cascading effects on associated data, or whether the operation is reversible.

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 extremely concise at only 4 words, but it sacrifices necessary detail for brevity. It is not fluff-free, it is underspecified.

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?

Given the tool has one parameter and no output schema or annotations, the description should provide more context about the operation's effects, success indicators, or error conditions. It lacks completeness.

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?

The input schema has 100% coverage for its sole parameter, already describing 'groupId' as 'Subscription Group ID'. The description adds no additional meaning beyond the schema.

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 clearly states the action ('Delete') and the resource ('subscription group'), making the primary purpose unambiguous. However, it does not differentiate from sibling delete tools beyond the resource name.

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 description provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or conditions (e.g., ensuring no active subscriptions before deletion).

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