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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful behavior notes — missing/null fields are passed through unchanged and monetary values keep their original unit and runtime type — but says nothing about freshness, coverage, or failure behavior for an open-world external lookup.

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?

Three short sentences, but the lead sentence is filler that duplicates the tool name, and the useful content (optional sections, null handling, monetary typing) is buried in later sentences rather than front-loaded.

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?

With no output schema, the description must carry the return-value burden, and it only partly does: it names the section structure and value-typing rules but never explains what 'core', 'channel', or 'portrait' actually contain, which an agent needs to decide whether to request them.

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 the schema already documents id, country (with its enum), and the include pattern. The description's mention of 'core, channel, and portrait sections' echoes the include parameter without adding format or interaction detail, so the 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?

The description identifies the resource as TikTok creator detail and mentions the returned pieces (base creator fields plus optional core/channel/portrait sections), but the opening clause 'Provider business records for TikTok Creator Detail' essentially restates the title rather than stating a specific verb like 'retrieves' or 'returns'. It also does not distinguish this tool from sibling lookups such as nexscope_chuhaijiang_tiktok_creator_search or the creator_related_* tools.

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 tool versus creator_search, creator_rankings_*, or creator_related_* siblings, and no hint that an id must first be obtained from a search. The only usage-adjacent information is which optional sections exist, which is already in the schema.

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