ebay_get_ad_groups

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

With no annotations, the description must fully disclose behavioral traits. It only states 'Get ad groups', implying a read operation, but fails to mention pagination (limit/offset), rate limits, authentication requirements, or any limitations.

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, which is concise, but it lacks structure and omits important details that could be included without becoming verbose.

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 large number of sibling tools and the complexity of eBay's API, the description is too minimal. It does not explain what an ad group is, the relationship to campaigns, or the expected return format. This is inadequate for an AI agent to reliably select and use the tool.

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 coverage is 100%, so the description is not required to add much. However, it adds no additional context beyond the parameter names, such as explaining adGroupStatus possible values or the necessity of campaignId. Meets baseline but no extra value.

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 'Get ad groups through the eBay Marketing API', specifying a verb and resource. However, it does not differentiate from sibling tools like ebay_get_ad_group (singular) or other campaign-related tools, preventing it from being a 5.

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. The required campaignId parameter is mentioned in the schema but not highlighted in the description, and no alternatives are listed.

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