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

The description frames the tool as a read/query ('查询…产品列表信息'), while the annotations declare readOnlyHint=false and destructiveHint=true. This is a direct conflict: the text promises a passive information lookup that the annotations say can mutate state. No additional behavioral context is supplied to reconcile the two.

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?

A single front-loaded sentence with no filler; the resource being queried comes first. It is efficient, though it is arguably under-specified rather than truly concise given the missing usage and safety context.

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 simple one-optional-param list tool with a complete schema and no output schema, the description is minimally adequate. However, the unexplained mismatch with the destructive annotations and the absence of any routing guidance against the many sibling scraper tools leave real gaps.

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 scraperType parameter is fully documented with its -1/0/1 enum meanings in the schema itself. The description adds nothing about parameters, so the baseline 3 applies since the schema carries the load.

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 gives a specific verb (查询/query) and resource (Dataify's web-scraping and SERP product list information), so an agent understands it returns a catalogue of Dataify offerings. It does not, however, differentiate itself from near-neighbour siblings such as scraper_serp_tools or scraper_serp_statistics.

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 the other scraper_* siblings, no prerequisites, and no exclusions. Usage must be inferred entirely from the name.

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