game_hot_rank_taptap

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description supplements this by specifying the return type (pandas.DataFrame) and the source URL, adding behavioral context beyond the annotations. It does not disclose data freshness or rate limits, but those are minor for a simple read tool.

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 concise, containing a title, URL, parameter documentation, and return type in a compact format. It is efficiently structured and front-loaded with the tool name, though it lacks a brief example or additional formatting that would make it even clearer.

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 the low complexity (single parameter) and rich annotations, the description covers the essential facts: what the tool does, where data comes from, parameter values, and return type. It could be more complete with an example output or column details, but for a simple list retrieval tool it is largely sufficient.

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 input schema provides no description for the 'symbol' parameter (0% coverage), but the description fully compensates by listing all valid enum values ('热玩榜', '热门榜', '新品榜', '预约榜', '热卖榜'). This is essential since the schema lacks an enum list.

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 clearly identifies the tool as fetching TapTap game rankings ('TapTap-游戏榜单') with the URL provided, and specifies the resource type (榜单/rankings). It distinguishes itself from the many financial/macro siblings by being solely about gaming platform rankings.

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 implies usage for obtaining TapTap game rankings but does not explicitly state when to use it over alternatives or provide any exclusion criteria. The URL and list types give context, but there is no explicit guidance on selecting this tool.

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