List TikTok niches

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

With no annotations provided, the description must reveal the tool's behavior. The word 'List' correctly implies a safe, read-only operation, but no additional behavioral details are shared (e.g., return format, size limits, or sorting). The description is minimal but not misleading, making a 3 appropriate.

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 a single, concise sentence that is front-loaded with the action ('List') and includes just enough context to be meaningful. Every word earns its place, with no redundancy or vagueness.

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 zero-parameter list tool with no output schema, the description is mostly complete. It states the purpose and resource type. However, it doesn't explicitly describe the return structure (e.g., array of strings) or clarify the slight terminology mismatch between 'niches' and 'account tags', which could leave minor ambiguity.

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 tool has zero parameters, so the baseline is 4. The description adds meaning by explaining the purpose of the output ('suggested account tags for local hook analysis'), which helps the agent interpret the result even though there is no input schema to elaborate.

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 uses a specific verb 'List' with a clear resource 'suggested account tags' and adds context 'for local hook analysis'. This distinguishes it from sibling tools like tiktok_hooks and tiktok_analytics by indicating it provides tag suggestions for niche/hook analysis.

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 phrase 'for local hook analysis' provides clear context for when to use this tool, implying it is relevant to analyzing local hooks. However, it does not explicitly mention alternatives or when not to use it, so it misses the top score for explicit exclusions.

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