ebay_get_email_report

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

No annotations provided. Description only states purpose, no disclosure of read-only nature, authentication needs, or any side effects. Fails to convey behavioral traits beyond the basic action.

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?

Single sentence, concise and front-loaded with key information. However, could benefit from slightly more detail without sacrificing brevity.

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?

No output schema, no explanation of report contents or scope. Unclear if it returns reports for all campaigns or requires specific context. Incomplete for a report 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% with parameter descriptions for limit and offset. Tool description adds no additional insight into how these parameters affect the report, so baseline 3 applies.

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?

Description clearly states 'Get performance report for email campaigns', specifying the verb and resource. It distinguishes from sibling tools like ebay_get_email_campaign and ebay_get_email_preview.

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 on when to use this tool vs. alternatives, no prerequisites or exclusions mentioned. Lacks context such as whether a campaign ID is needed.

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