Pricelist

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does convey that the operation is a read-only fetch (via 'Fetch') and that it is scoped to the authenticated account, which is useful. However, it does not explain the return format, any potential costs, or rate limits, and the term 'full' is vague.

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, focused sentence that directly explains the tool's purpose with no wasted words. It is well-structured and easy to parse.

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 no parameters, no output schema, and no annotations, the description is minimal but adequate for a simple getter. However, the existence of a sibling tool named 'get_pricelist' creates ambiguity that the description fails to resolve, and the lack of output schema details leaves the agent uncertain about the response structure.

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, so the baseline for this dimension is 4. The description's mention of 'for the authenticated account' adds context about implicit scoping that is not captured in the empty parameter list, slightly enhancing the value.

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 tool fetches the full TLD pricelist for the authenticated account, using a specific verb and resource. However, it does not distinguish itself from the sibling tool 'get_pricelist', which likely serves the same purpose, so it is not fully differentiated.

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 like get_pricelist or get_tld_info. The usage is only implicitly implied by the action 'Fetch', with no mention of exclusions or preferred contexts.

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