GetSubscription

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

No annotations are present, and the description lacks any behavioral context such as read-only nature, authentication requirements, or side effects. It only reiterates the action without additional detail.

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 short (one sentence) but lacks substance. It is underspecified rather than concise, providing minimal information that does not earn its place given the tool's context.

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 that there is no output schema and no additional context, the description is incomplete. It does not explain what a subscription is, what data is returned, or how the tool fits into the broader workflow.

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 tool has zero parameters and schema description coverage is 100% trivially. The description does not need to add parameter information, and no further meaning is necessary beyond what the empty schema implies.

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 'Get a subscription to the orders' indicates a read operation on a subscription resource, which is clear as a verb+resource. However, it is somewhat vague because it does not specify which subscription or how it is identified, and it does not differentiate from sibling tools like GetSubscriptionList or GetSubscriptionPushReporting.

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?

No usage guidelines are provided. The description does not state when to use this tool, when not to use it, or any alternatives among the many sibling subscription-related tools.

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