get_hot_words

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

No annotations are provided, so the description carries the full burden, and it discloses nothing behavioral: no indication that it is a read-only list, nothing about how many words come back, freshness of the ranking, or whether results are paged. Only the purpose is conveyed.

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?

Two compact sentences with the resource and its use front-loaded and no filler. The gender mapping is slightly redundant with the schema, keeping it from a 5.

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?

For a one-parameter read tool this is close to adequate, but with no annotations and no output schema the description should at least say what the response contains (a ranked list of words) or that it is a safe read. As written an agent can call it but not predict the result.

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 coverage is 100% and the single gender parameter is already fully documented in the schema, so the description's '1=男频，2=女频' merely repeats it without adding syntax or default behaviour (the default of 1 lives only in the schema). 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 resource – the in-site hot-words ranking – and adds an intended use (naming books / riding traffic). It is distinguishable from the sibling get_douyin_hot_list, though it never names that sibling as the alternative.

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 parenthetical '起书名 / 蹭流量用' implies when to reach for it, but there is no explicit when-not and no pointer to get_douyin_hot_list for off-site trends. Usage is implied rather than stated.

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