ebay_get_negative_keywords

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

No annotations provided; description mentions access requirement but lacks details on pagination, return format, or rate limits. Adequate for a simple read operation.

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?

Two concise sentences cover purpose, filters, and requirement with no fluff. Front-loaded with key action and resource.

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?

Sufficient for a parameterized get tool: mentions campaign type, optional filters, and access requirement. Missing return value description but acceptable given no output schema and simplicity.

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 baseline is 3. Description adds context by grouping filters ('campaign, ad group, or status'), complementing schema descriptions without adding new syntax.

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?

Describes a specific verb ('Get') and resource ('negative keywords') with context ('for priority-strategy CPC campaigns'), clearly distinguishing from siblings like 'ebay_create_negative_keyword' or 'ebay_get_negative_keyword' (singular).

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?

States optional filters and a prerequisite ('Requires eBay priority strategy program access'), providing clear context. Does not explicitly exclude alternatives, but the specificity is sufficient.

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