Script from a TikTok ad

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

The readOnlyHint=true annotation covers the safety profile, and the description usefully clarifies the artifact produced ('shot-by-shot script you can film yourself'). It does not say how the source ad is selected, whether the result is persisted, or any auth/rate behavior, so it adds modest value over the annotation.

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?

One tight sentence, front-loaded with the input (TikTok ad) and the output (shot-by-shot script), with no filler. Every clause 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?

The description explains what comes out but not what goes in or how the source ad is identified, which matters because the schema declares no parameters while additionalProperties is open. With no output schema, the description is the only source of return-shape context and it is thin, though adequate for a simple generation tool.

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 takes zero parameters, so there is nothing for the description to document; the baseline for a 0-param tool applies. No parameter-level detail is expected or missing.

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 transformation: a TikTok ad in, a shot-by-shot script for the user's own product out. That verb+resource pairing is clear. However, it never distinguishes this from the many clone_* siblings (clone_ad, clone_video_ad, clone_from_script), which an agent will have to disambiguate on its own.

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 when-to-use guidance, no exclusions, and no mention of the closely related clone_ad / clone_video_ad / clone_from_concept tools. With five-plus clone variants in the sibling set, the absence of routing guidance is a real gap.

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