ebay_bulk_update_campaign_negative_keywords

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

No annotations are available, so the description carries full burden. It only says 'update' but does not disclose whether updates are partial or full replacement, that it requires existing negative keyword IDs, or any error/response semantics. This is insufficient for safe invocation.

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 very short (one sentence) and concise, but it sacrifices important context. It is not front-loaded with critical usage details like the need for existing keyword IDs.

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 lack of output schema and annotations, the description should provide more behavioral context, such as whether it performs a full replace or partial update, and what the response contains. It fails to do so, making it incomplete.

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 input schema already describes all parameters. The description adds no additional meaning beyond the schema. Baseline score of 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 'Update multiple campaign-level negative keywords.' It specifies the verb (update) and resource (campaign-level negative keywords) and implies bulk operation via 'multiple'. It distinguishes from create/delete siblings, but could be more explicit about updating existing keywords by ID.

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 like ebay_bulk_create_campaign_negative_keywords or ebay_bulk_delete_campaign_negative_keywords. The description does not mention exclusions or prerequisites.

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