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

With no annotations, the description carries the full behavioral burden. It discloses that the tool is 'Free' and lists several outputs, but omits permissions, side effects, network behavior, data freshness, and what happens when providers are unhealthy or payment status is unavailable.

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, front-loaded sentence with no filler. It is appropriately terse for a simple two-parameter tool, though the phrase 'Our price' is slightly ambiguous.

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 no annotations, no output schema, and a misleading url schema description, the description is not complete enough to call the tool confidently. It lists some outputs but leaves the core relationship between the url input and the quote result undefined.

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 coverage is 50%, and the description only implicitly references the 'tier' parameter via 'price for a tier' without explaining the url parameter at all. Worse, the schema's url description says 'convert to markdown,' which conflicts with the quote purpose, and the description does nothing to clarify the actual role of url.

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 lists return data (price for a tier, healthy provider count, latency, payment status) but does not state a clear action verb or explain what the tool does with the required URL. The title 'Price and availability' helps, but without the title the purpose is vague and it never differentiates itself from the sibling scrape tools.

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 guidance on when to use this tool versus scrape or scrape_lite, nor any when-not-to-use conditions. The description merely lists outputs and leaves the agent to infer the tool's role.

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