Billing Subscriptions Get

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

The annotations provide high transparency regarding safety (readOnlyHint, destructiveHint). The description primarily adds technical metadata (HTTP path, scope, version) rather than explaining behavioral constraints like rate limits or failure modes. The description adds marginal value beyond what the structured fields already communicate.

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 definition is appropriately sized and highly efficient. It immediately front-loads the purpose and then follows with concise technical implementation details without extraneous language.

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 high richness of the annotations and the comprehensive input schema coverage, the description provides a complete operational overview. It specifies the technical context (API path, scope) necessary for an agent to confidently execute the call.

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 descriptions for the parameters add meaningful context beyond the schema. Specifically, it clarifies the origin of the 'service_id' (Partner Portal) and provides usage examples for the 'fields' parameter to reduce payload size.

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 identifies the resource ('subscription(s)') and the context ('app service') using a specific action verb ('Get'). It is highly descriptive, though it could be slightly clearer by contrasting it with related subscription tools (e.g., those for orders).

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?

Usage is implied by the resource name and API path, but the description provides no explicit guidance on when to use this tool versus alternatives. An agent might confuse 'app service' subscriptions with customer 'order' subscriptions present in the sibling tools list.

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