ebay_get_email_audiences

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

The description implies a read-only operation ("Get") and no destructive behavior, which aligns with the absence of annotations. However, it does not disclose any behavioral constraints, permissions, or potential costs. Since no annotations exist, the description partially informs but lacks depth.

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 unnecessary words. It is front-loaded and efficiently conveys the purpose.

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?

Despite zero complexity in terms of parameters, the description lacks completeness by not explaining what 'audiences' are or what the response contains. With no output schema, agents need more context to interpret results correctly. The description is too sparse for effective use.

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?

With zero parameters, the description does not need to elaborate on parameter semantics. The baseline score of 4 applies as per guidelines; the description is adequate for a parameter-less tool.

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 states it retrieves audiences for email campaigns, clearly specifying verb and resource. It distinguishes from sibling tools like ebay_get_email_campaigns (which gets campaigns) and ebay_create_email_campaign (which creates), but could be more specific about what constitutes an audience.

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. It lacks context such as prerequisites, when to call it before creating a campaign, or exclusions. Without this, agents may not understand the appropriate context.

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