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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds useful behavioral context by listing the kinds of data returned (prices, inclusions, suitability, order links), but it does not say the catalog is static, whether the list is exhaustive, or how ordering links behave.

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?

One compact sentence with no filler, and the resource is front-loaded before the payload details. It reads as a noun phrase rather than a complete sentence, but every element earns its place.

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?

For a single-parameter, read-only catalog tool with a fully described enum and no output schema, the description does the important remaining work of previewing what the response contains. Only the absence of sibling routing guidance keeps it from being complete.

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 100% and the single 'type' enum is documented with its default in the schema, so the description has nothing to compensate for. It adds no extra meaning about the hosting/vps distinction beyond what the enum already conveys, which matches the baseline for full coverage.

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 names the resource concretely (web hosting and VPS plans) and enumerates the payload an agent will get back: BDT monthly/yearly prices, inclusions, target audience, and order links. That is far more specific than the tool name alone and separates it from domain_prices and order_link, though the verb ('list') is only implied by the name rather than stated.

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?

There is no statement of when to call this versus siblings such as domain_prices (for domain pricing) or order_link (for actually placing an order). The mention of 'order links' hints at a relationship with order_link but the description never says to use this tool for browsing and order_link for purchasing, so the agent must infer routing.

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