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

No annotations are provided, so the description carries the burden. It does disclose the shape of the returned content (categories, price ranges, delivery cycles), which is useful. However, it says nothing about authentication needs, result limits, or whether the lookup is static or live.

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?

Front-loaded with the resource and its dimensions, then examples; every clause carries information. Slightly dense with the long enumeration and example list, but nothing is filler.

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?

With no annotations and no output schema, the description still communicates what the tool returns and when to reach for it, which is adequate for a one-parameter catalog lookup. Missing only edge-case behavior such as what happens with an unrecognized category.

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 optional 'category' parameter is documented in the schema with the same keyword list. The description adds no syntax or filtering behavior beyond what the schema already provides, 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 (查询) plus resource (软件定制开发服务类目、报价区间与交付周期) and enumerates the concrete domains covered (小程序/官网/H5/OA/ERP/数据平台). This clearly separates it from the bidding-oriented siblings.

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?

Gives three representative user phrasings ('开发一个微信小程序什么价位', '企业官网定制服务内容', 'H5制作交付周期') that map directly to this tool, so an agent can match intent. It does not name alternative tools or exclusions, but the bidding siblings are obviously a different domain.

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