wop_overview

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

No annotations are provided, so the description carries the full burden. It discloses the scope of returned content (three-step flow, securityReq algorithm, public-key encoding, SDK/tool list, live llms.txt index grouped by domain) and notes the index is pulled in real time. It is clearly a non-destructive read; the only gap is it does not discuss caching/refresh behavior beyond '实时拉取'.

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 purpose, then a content inventory, then sibling routing, then a brief Returns line. Every sentence contributes; the content enumeration is dense but useful rather than padding.

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?

An output schema exists, so return values need not be spelled out, yet the description supplies a markdown-format note and full content inventory. For a parameterless overview/entry-point tool this is complete enough to invoke correctly.

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?

The tool takes zero parameters, so the schema baseline of 4 applies. There is nothing further the description could meaningfully add about inputs.

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 (获取/get) and resource (WOP 接入指南与全部 API 索引), and enumerates the exact contents. It also names the two sibling tools (wop_api_detail, wop_link_detail) that handle the follow-up detail, so the agent can distinguish it from them without opening a schema.

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 description routes the agent: index APIs are fetched in detail via wop_api_detail, links via wop_link_detail, implying this tool is the entry point that produces the index. It stops short of an explicit 'call this first' statement or an exclusion rule, so it falls just short of a 5.

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