get_creative_details

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

No annotations are provided, and the description does not disclose any behavioral aspects beyond the basic 'get' operation. It doesn't mention required permissions, potential errors, rate limits, or what fields are returned (though an output schema exists). The description adds little beyond what is obvious from the tool name.

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 succinct, front-loaded with the core purpose, and uses a well-structured Args list for parameters. Every sentence adds value; there is no fluff or redundancy.

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 the tool's simplicity (2 params, output schema present), the description adequately covers its purpose and parameters. It doesn't describe return values, but the output schema handles that. The only missing context is broader usage guidance, which is scored separately.

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 0% coverage, but the description's Args section explains both parameters: creative_id as a Meta Ads creative ID (required) and access_token as an optional Meta API access token. This adds meaningful semantics beyond the bare type/title in the schema, though it doesn't elaborate on value formats or edge cases.

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 gets detailed information about a specific ad creative by ID, using a specific verb and resource. It distinguishes from sibling tools like get_ad_creatives (which likely lists) and get_ad_details (which targets ads rather than creatives).

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 provides clear context: use when you have a specific creative ID and need its details. It doesn't explicitly exclude alternatives or mention when not to use it, but the 'by its ID' phrasing implies single-item retrieval rather than listing.

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