wechat_search_ai_articles

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

No annotations are provided, so the description carries full burden. It only mentions keyword requirement and date format, but omits behavioral traits like pagination, sorting, rate limits, or any side effects. The output schema exists but is not referenced.

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 extremely concise: two sentences providing key information without filler. Purpose is front-loaded, and every word adds value.

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?

Given 5 parameters, no annotations, and an output schema, the description is too sparse. It covers the required keyword and date format but leaves pagination behavior, result structure, and usage compared to sibling tools unaddressed. An agent would have gaps in effectively using this tool.

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 0%, requiring the description to compensate. It explains the keyword parameter and date format for start_time/end_time, but does not mention page_num or page_size parameters, nor explain the semantic meaning of the date range (e.g., filter by publication time).

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 specific verb (search) and resource (WeChat Official Account AI-related articles from a high-quality database). It clearly distinguishes from sibling tools like wechat_search_articles (general search) by narrowing to AI creations and using '优质库'.

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?

No explicit guidance on when to use this tool versus alternatives such as wechat_search_articles. The description does not provide context for selection, it only gives required parameter and date format.

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