tiktok get creatives

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 read-only behavior is covered. The description adds minimal context about the content types returned but does not disclose pagination behavior, authentication needs, or how the optional adIds affect the result scope.

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, front-loaded sentence with no filler. The parenthetical '(video, image, text)' efficiently conveys the returned content types without extra prose.

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 output schema, complete parameter descriptions, and safety annotations, the description is largely adequate for a read-only retrieval tool. The only gap is that it doesn't specify whether omitting adIds returns all creatives for the advertiser, which could affect how an agent invokes it.

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 the schema already documents advertiserId, adIds, and limit with defaults and bounds. The description adds no new parameter semantics beyond the general phrase 'for specific ads,' so the 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 gives a specific verb and resource—'Get creative details (video, image, text) for specific ads'—so an agent can understand what the tool returns. It doesn't explicitly differentiate from sibling tools like tiktok_get_ads or tiktok_list_ad_videos, but the resource and content types are clear.

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 the tool is for retrieving creative details, but it gives no guidance on when to use this tool versus siblings such as tiktok_get_ads, tiktok_get_video_assets, tiktok_list_ad_videos, or tiktok_list_ad_images. There is no mention of exclusions or alternatives.

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