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

Annotations declare readOnlyHint=false and openWorldHint=true, but the description never explains any side effect, permission requirement, or cost, nor why a 'detail' retrieval tool is marked non-read-only — a real transparency gap. The only added context is output-shaping behavior ('missing and null fields remain unchanged; monetary values retain their original unit and runtime type'), which is useful but narrow.

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?

Only two sentences and nothing redundant, but the leading sentence is boilerplate that restates the title, wasting the front-loaded position where the actual purpose should sit.

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 is simple (3 params, flat schema, no output schema) and annotations exist, so the description is minimally sufficient. It still leaves unclear how the returned sections relate to the include parameter and how this differs from the many sibling creator tools.

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 id, country, and include are all already documented in the schema. The description's mention of 'optional core, channel, and portrait sections' echoes the include enum without adding format, default, or precedence semantics. Baseline 3 applies when the schema carries the burden.

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 first sentence, 'Provider business records for TikTok Creator Detail,' largely restates the tool title and never names a verb like 'retrieve' or the keying resource (a single creator by ID + market). The second sentence does add substantive information — that base creator fields plus optional core/channel/portrait sections are returned — which pushes it above pure tautology. It offers no differentiation from siblings such as nexscope_chuhaijiang_tiktok_creator_search or nexscope_chuhaijiang_tiktok_creator_related_products.

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 guidance on when to use this versus the creator search, rankings, or related_* tools, and no stated prerequisite such as needing a creator ID obtained from search. Usage must be inferred entirely from the tool name.

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