creatives_get

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

With no annotations provided, the description must carry the full burden of disclosing behavior. It indicates a read operation via 'Get', but provides no additional context such as error handling, required permissions, or response structure. This is minimal and leaves important behavioral aspects unaddressed.

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 unnecessary words. It efficiently conveys the core purpose and is appropriately sized for a simple retrieval 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?

For a straightforward get-by-ID tool with a single parameter and no output schema, the description is adequate but not comprehensive. It does not describe the return fields or error scenarios, but given the low complexity, the gap is not severe.

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 schema has one required parameter, creative_id, but no description coverage (0%). The tool description mentions 'a single ad creative' but does not explicitly map to the creative_id parameter or explain its format. The description adds little beyond what the parameter name already implies.

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 clearly states the tool retrieves 'full details of a single ad creative', using a specific verb ('Get') and resource ('ad creative'). It effectively distinguishes from sibling tools like creatives_list (which lists multiple) and creatives_delete (which removes).

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 usage when a single ad creative needs to be fetched by ID, but it does not explicitly state when to prefer this over alternatives or mention any exclusions. While the purpose is obvious, there is no explicit guidance on prerequisites or when not to use.

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