tiktok_profile: GET /

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

No annotations are provided, so the description must carry the full behavioral burden. It accurately conveys that this is a read operation (fetches) on public profiles, but it does not disclose potential edge cases like errors for non-existent handles, rate limits, or authentication requirements. For a simple GET it is acceptable but not exhaustive.

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 compact, front-loaded with the tool's purpose, and avoids unnecessary fluff. The second sentence adds value by listing return fields and use cases. It is efficiently written without waste.

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 single-parameter tool with no output schema, the description covers the essential information: what it does, what it returns, and typical use cases. It does not discuss error handling or output formatting, but given the simplicity of the operation, it is sufficiently complete for an agent to invoke it.

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 single parameter 'handle' is fully documented in the schema with an explanation of format (with or without '@'). The description adds no additional semantics beyond restating the parameter name. Since schema coverage is 100%, the baseline of 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 clearly states it fetches a public TikTok profile by username and enumerates the exact data returned (nickname, bio, counts, flags). It is specific about the resource and action, and its distinctness from sibling tools (comments, posts, search) is evident from the resource type.

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 provides clear usage contexts (CRM enrichment, influencer vetting, competitor monitoring) which implicitly distinguish it from siblings that handle posts, comments, or search. It does not explicitly state when not to use it or name alternatives, but the context is unambiguous enough for an agent to select it correctly.

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