ebay_bulk_create_campaign_negative_keywords

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

Annotations are missing, and the description does not disclose behavioral traits such as idempotency, whether it replaces or appends, rate limits, or error handling. For a bulk creation tool, more transparency is needed.

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 short sentence, which is concise but lacks detail. It is front-loaded but could benefit from more context without being 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 complexity (nested objects in input schema) and absence of output schema and annotations, the description is incomplete. It does not explain the response format, error scenarios, or any prerequisites.

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 schema already documents all parameters. The description adds no additional meaning beyond what the schema provides. Baseline 3 is appropriate.

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 action ('create') and the resource ('multiple campaign-level negative keywords'). It distinguishes from siblings like 'ebay_create_campaign_negative_keyword' (singular) and 'ebay_bulk_delete_campaign_negative_keywords' (delete).

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 explicit guidance on when to use this tool vs alternatives. It does not mention that this is for bulk creation, while there is a singular version available. The context of sibling names implies it, but no direct instructions.

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