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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows it is a safe read operation. The description adds that it returns recommended keywords with volume estimates, which is useful but not extensive. There is no contradiction, and the annotation coverage means the description doesn't need to carry the full burden.

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?

Two sentences with no redundancy. The purpose is front-loaded, and the return detail is stated succinctly. Every word earns its place.

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 a rich annotation set covering safety and idempotency, a complete parameter schema, and an output schema (has_output_schema=true), the description covers the core purpose and return shape. It doesn't mention any prerequisites or caveats, but given the overall context, nothing critical is missing.

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 all three parameters (advertiserId, keywords, limit) are already documented in the schema. The description adds no extra parameter-level semantics beyond what the schema provides, so a baseline 3 is appropriate.

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 states a specific verb (get), resource (keyword suggestions), and context (TikTok Search Ads), plus the return value (keywords with search volume estimates). It is unambiguous and distinct from the many sibling tools, which are all about audiences, ads, campaigns, or reports.

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 implies this is for generating keyword suggestions but does not explicitly state when to prefer it over alternatives or when not to use it. No exclusions or alternative tool references are given, leaving the agent to infer the context from the tool name and description.

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