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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so safety is covered elsewhere. The description adds nothing — no mention of pagination behavior, result ordering, quotas, or what a missing/invalid id yields.

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?

It is a single short sentence with no filler, so nothing is padded. However, that brevity comes from having almost no content rather than from disciplined editing, leaving it under-specified rather than tight.

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 tool with no output schema and a paginated, id-driven data lookup, the description supplies none of the context an agent needs: what the response contains, how pagination terminates, or how this endpoint differs from the many other CJ creator endpoints.

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 coverage is 100%, so all four parameters (id, country, page, pageSize) are documented in the schema itself, which sets the baseline at 3. The description adds no extra meaning — notably it does not clarify that 'id' is a creator/expert ID or that pageSize caps at 10 alongside pagination semantics.

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 restates the title and tool name ('TikTok Commerce Intelligence CJ: creators/related videos API') without a verb or any explanation of what a 'related videos' lookup returns. It does not distinguish this from close siblings like nexscope_data_cj_creators_related_lives or nexscope_data_cj_creators_related_products.

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 the many sibling creator/video endpoints, no prerequisites (e.g. that an expert/creator id must first be obtained from a detail or search call), and no exclusions stated.

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