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

Annotations declare openWorldHint=true and readOnlyHint=false, which is notable for an endpoint whose name says 'detail'; the description neither confirms nor clarifies the read/write posture, required auth, or rate limits. It adds nothing beyond the structured annotations — no mention of response shape, data freshness, or per-region availability.

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?

One short sentence with no wasted words, but the brevity here is under-specification rather than conciseness — nothing is front-loaded because there is nothing to front-load. The text is effectively a second copy of the title.

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 seven-parameter tool with no output schema and ambiguous read/write annotations, the description should explain what a creator detail payload is and how it relates to the sibling creator tools. None of that is present, leaving the agent to infer everything from the parameter names.

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%, and all seven parameters (creatorId, region, shop_id, currency, language, dateRange, category_ids) carry their own descriptions and examples. The description adds no semantics beyond that, which is the expected baseline when the schema does the work, but 'dateRange' semantics interacting with creator metrics go unexplained.

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 is a restatement of the title and name: 'TikTok Intelligence KD: creator/detail API.' It implies retrieval of creator detail for the KD (TikTok) data source, but supplies no verb, no scope, and no statement of what a 'creator detail' record contains. It also does nothing to separate itself from near-identical siblings such as nexscope_data_kd_creator_rank, nexscope_chuhaijiang_tiktok_creator_detail, or nexscope_tiktok_creator_analytics.

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?

There is no when-to-use, when-not-to-use, or alternative routing information of any kind. An agent cannot tell from this text whether to call it before or after a creator search, or how it differs from nexscope_data_kd_creator_rank or nexscope_tiktok_creator_analytics.

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