ads_create

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

No annotations are provided, so the description must cover behavioral traits. It only states the action (create) and the binding concept, lacking details on side effects, error handling, rate limits, or auth requirements.

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 sentence that efficiently conveys the core purpose. It is front-loaded with the action, though additional structure (e.g., bullets) could improve readability.

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 no output schema and a complex nested input, the description is insufficient. It does not explain what the tool returns (e.g., ad ID) or provide completeness for a creation operation. Required fields and allowed additional properties are unmentioned.

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 description adds meaning for 'creativeId' and 'creativeType' by explaining the creative binding and wrap types. However, schema coverage is low (25%), and other parameters (campaignId, adGroupId, ad.name, ad.status) lack description, leaving gaps.

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 creates an ad and describes its binding to a creative. It distinguishes from sibling tools like ads_delete or ads_update, but does not explicitly differentiate from ads_create's own sibling set.

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 context (creating an ad in an ad group) but provides no guidance on when to avoid this tool, prerequisites, or alternatives. Sibling tools for ad management are present but not referenced.

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