ebay_bulk_create_negative_keywords

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

No annotations are provided, so the description carries full burden. It only hints at creation behavior (non-destructive) but does not mention rate limits, authentication needs, or any additional behavioral traits beyond the core purpose.

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 redundant information. It is concise but could be slightly more structured by separating purpose and context, though overall it is well-sized.

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?

The description is adequate for a simple bulk creation tool, but lacks mention of return values, atomicity of the batch operation, or constraints like 'CPC campaigns only'. Given no output schema, more detail would improve completeness.

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 detailed descriptions for each parameter. The tool description does not add any additional semantic meaning beyond what is already in the schema, so it earns the baseline score of 3.

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 it creates multiple negative keywords in bulk, and differentiates this from other tools like 'ebay_create_negative_keyword' (single) and 'ebay_bulk_update_negative_keywords' (update). The additional context 'for priority-strategy CPC campaigns' further specifies the use case.

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 for bulk creation vs. single creation, but does not explicitly state when to use this tool over alternatives, nor does it provide any prerequisites or exclusions. It gives limited guidance on context.

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