ebay_bulk_update_negative_keyword

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

With no annotations, the description must disclose behavioral traits. It only states the API is used, but does not mention any side effects, idempotency, or what happens to existing keywords. The bulk update nature implies mutability, but specifics are missing.

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 sentence, which is concise but sacrifices necessary detail. It could be expanded without losing 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?

Given the complexity of a bulk update with nested objects and no output schema, the description is inadequate. It does not cover return values, prerequisites, or constraints, leaving the agent underinformed.

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?

The description does not explain the 'request' parameter beyond its schema label. The nested properties 'negativeKeywordId' and 'negativeKeywordStatus' lack descriptions, and the tool's description adds no meaning. Schema coverage is 100% only at the top level, leaving nested parameters undocumented.

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 tool performs a bulk update of negative keywords through eBay's Marketing API. It is distinguished from siblings like 'ebay_update_negative_keyword' (single) and 'ebay_bulk_create_negative_keyword' (create vs update). However, it lacks context about what negative keywords are in eBay.

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 such as 'ebay_update_negative_keyword' for single updates or 'ebay_bulk_create_negative_keyword'. There is no mention of prerequisites or scenarios.

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