tiktok get carousel music

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

Annotations already flag read-only/idempotent/non-destructive, and the description reinforces safety while adding the non-obvious behavior that it 'verifies each image is carousel-usable.' It also explains the downstream workflow—select a returned music_id in the approval preview and reuse the same images—and the TikTok-only restriction, which are useful context beyond annotations.

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?

Three sentences, each earning its place: the first states the core action and scope, the second reveals verification and read-only behavior plus the follow-up workflow, and the third restricts usage. Information is front-loaded and no filler is present.

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 only two schema-covered parameters, an output schema, and annotations that establish safety, the description covers the operational context an agent needs: when the call applies, what it validates, and what to do with the result. The main workflow note about approval preview and matching image IDs makes the tool self-sufficient for correct invocation.

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?

Both parameters are already fully described in the schema (100% coverage), including 'ordered list of 1-35 distinct uploaded image IDs' and the exact numeric ID requirement, so the description carries no additional load. The description only restates the same-images requirement rather than adding new parameter detail, matching the baseline-3 standard for full schema coverage.

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?

Opens with 'Get TikTok music recommendations', naming a specific verb and resource. Scope is sharpened by 'for exactly the uploaded images in a standard, non-catalog image ad (one card) or carousel', which distinguishes it from the sibling read tools. No ambiguity about what it returns.

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 clearly states the intended use case: music recommendations for a standard non-catalog image ad or carousel built from the exact uploaded images. It implicitly excludes catalog ads but does not name a fallback or explicitly say when not to use it, so it falls one step short of full exclusionary guidance.

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