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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=false, so the bar is lowered. The description adds that it submits an async Builder task with a fixed collector ID, which is consistent with the write annotation. It does not explain what is destructive, auth requirements, rate limits, or how results are later retrieved (sibling scraper_task_result/status), leaving meaningful behavioral gaps.

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 trigger list is verbose and redundant — 酒店信息, 酒店详情, hotel information, hotel list and five near-synonymous action verbs all express the same intent. The action statement is front-loaded enough, but the keyword padding dilutes the signal.

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?

There is no output schema, and this is an async task-submission tool with destructive/idempotent-false annotations. The description states the task and collector ID but omits the workflow an agent needs (that results come from a separate task-result tool) and any caution about the destructive write. Adequate but incomplete.

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%, so both parameters are already documented, making 3 the baseline. The description only echoes the collector identifier tied to the url parameter and adds no format or validation nuance beyond the schema.

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 second sentence names a specific verb+resource: submitting a Booking hotel information collection Builder task with a fixed collector identifier. It distinguishes the tool as Booking-specific against siblings like google_hotels. It falls short of 5 because the primary action is buried behind a trigger-phrase list and it doesn't clarify list-vs-detail scope.

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 first sentence explicitly states the triggering condition — when the user needs Booking hotel information/detail/list paired with verbs like 采集/抓取/爬取/获取/提取. This gives clear context for when to use it. However, it names no alternatives (e.g., google_hotels or other scraper tools) and offers no exclusion criteria, so it stops at 'when' without 'when not'.

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