wechat-search

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It only restates the search action and does not mention result ordering, pagination, rate limits, freshness, caching, or what qualifies as '爆款', leaving the tool's runtime behavior opaque.

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 description is a single short sentence with no filler and is easy to scan. It has slight redundancy because '公众号文章搜索' and '公众号爆款文章' overlap, but it remains efficient and front-loads the resource and action.

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?

The tool has a simple input schema and no output schema or annotations, so the description should at least hint at the return value and behavior. It does not explain what the output looks like, what '爆款' means, or how maxItems and startDate affect results, leaving an important gap for the agent.

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 the input schema already documents keyword, maxItems, and startDate. The description adds minimal semantic context by mentioning '关键词' and '爆款文章', but it provides no extra detail about maxItems or startDate beyond what the schema already states.

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 states a clear action ('搜索') and resource ('公众号文章'), and narrows it to '爆款文章', so an agent can tell this is a keyword-based article search. It does not explicitly differentiate from sibling tools like wechat-10w-hot or wechat-original-hot, but the core purpose is still unambiguous.

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 phrase '按关键词搜索' implies the tool is for keyword-driven searches, which gives some usage direction. However, there is no explicit guidance on when to prefer this tool over sibling search or hot-list tools, and no alternatives or exclusions are mentioned.

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