get_subscription_initial_addons

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

Annotations are absent, so the description carries the full burden. It discloses a read-only operation via 'List' and the permission tier 'readonly-owner', which is useful context. However, it does not describe response format, error handling, or the meaning of 'initial-service addons', leaving some ambiguity.

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, with a single sentence plus endpoint and tier in brackets. Every element earns its place: action, scope, API mapping, and permission level. No redundancy or filler.

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?

With one parameter, no output schema, and no annotations, the description covers the core purpose and permission level. However, it omits any description of return values (since no output schema exists) and lacks guidance on when to use this over sibling tools. It is adequate for a simple list operation but not comprehensive.

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 does not mention the sole parameter 'subscriptionID'. While the parameter name is intuitive, the description adds no meaning beyond the schema and fails to compensate for the lack of schema descriptions.

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 a specific action ('List') and resource ('initial-service addons on a subscription'), distinguishing it from sibling tools like get_ticket_addons. The explicit API mapping to POST /subscription/getInitialAddOns adds precision and reinforces the purpose.

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 does not explicitly state when to use this tool versus alternatives, nor does it provide exclusions. The tier 'readonly-owner' gives a permission context, but no alternative tools are mentioned, so usage guidance is only implied by the resource name.

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