creatives_list

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

The description claims to list 'all' creatives, but the schema includes a default limit of 50, suggesting pagination or partial results may occur. No mention is made of pagination behavior, rate limits, or that the default limit may prevent fetching all creatives in one call. With no annotations, the description carries the full burden, and this omission is misleading.

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, clear sentence with no wasted words. It front-loads the core action and resource, which is ideal for a simple list tool.

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 tool is simple, but the description omits important context such as the meaning of the limit parameter, pagination behavior, and how this tool relates to more specific list siblings. The claim of 'all' is ambiguous given the limit default. Enough for a basic list, but has clear gaps.

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 0%, so the description must compensate. It only indirectly references account_id ('in an account') and ignores the limit parameter entirely. No additional meaning is provided beyond the parameter names in the schema.

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 uses a specific verb ('List') with a clear resource ('ad creatives') and scope ('in an account'). It distinguishes itself from sibling tools like creatives_list_images and creatives_list_videos by indicating it lists all creatives, not just a specific type.

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?

No guidance is provided on when to use this tool versus alternatives such as creatives_list_images or creatives_list_videos. The description only states what it does, not the context or exclusions.

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