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

The annotations already declare readOnlyHint=false, destructiveHint=true, openWorldHint=true and idempotentHint=false, so the safety profile is covered. The description adds that this is an asynchronous Builder task submission with a fixed collector ID, which is useful beyond the annotations, but it never says what the task produces or how results are retrieved.

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 sentence about submitting the Builder task is front-loadable and clear, but the first sentence is a long enumeration of synonyms (采集、抓取、爬取、获取、提取) that inflates size without adding routing precision beyond a couple of keywords.

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 task-submission tool with no output schema, the description omits the crucial workflow fact that it only enqueues work and that results must be fetched via siblings such as scraper_task_status / scraper_task_result. With destructiveHint=true and no output schema, this leaves the agent without the follow-up path it needs.

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% (url and file_name both documented inline with required/default notes), so the schema carries the parameter meaning. The description adds nothing about parameters except the fixed collector identifier, so the baseline 3 applies.

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?

States a specific verb+resource: submits a collection Builder task for Amazon seller info, with the collector fixed as amazon_seller_by-url. It is clearly distinguishable from siblings like amazon_product or amazon_comment by resource, though it spends much of its length on trigger-word enumeration rather than the action itself.

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?

It gives explicit trigger conditions (user needs Amazon seller info combined with collection verbs such as 采集/抓取/获取), which is usable context. However, it names no alternatives and no when-not conditions, so the agent still has to infer why it would pick this over the other amazon_* siblings.

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