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

No annotations are provided, so the description should carry the full burden of disclosing behavioral traits. It does not state that the operation is read-only, nor does it mention rate limits, data modification, or other side effects. The absence of such details leaves behavioral transparency incomplete.

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 moderately concise and well-structured. It conveys the core functionality and relevant details without unnecessary verbosity, though it could be slightly tighter by removing redundant phrasing like repeating 'hasdataLink' and 'hasdataPostsLink'.

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?

Given the absence of an output schema, the description does well to enumerate the return fields (e.g., description, likes, comments, author) and explain pagination. It also gives practical use cases. Minor gaps include not explaining the structure of the nested author/user objects or the exact format of the response envelope.

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 schema already covers all parameters with descriptions (100% coverage), and the tool description adds some context about pagination usage. However, it largely repeats the schema information without significantly deepening understanding, so it provides marginal added value.

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 the tool searches TikTok by keyword and returns videos or users, with a list of fields. It also names specific use cases like content discovery and trend research, making the purpose unambiguous.

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 guidance on when to use the tool (content discovery, trend research, etc.) and explains pagination with nextPageToken. However, it does not explicitly contrast with sibling tools, though the distinct focus on search is implicit.

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