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

With no annotations, the description carries full burden but only states the basic operation. It does not disclose whether the operation is atomic, handles duplicates, requires active campaigns, reports partial failures, or has rate limits. Important behavioral traits for a bulk mutation 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 lacks necessary detail. It is not verbose, but the brevity comes at the cost of completeness. Every word earns its place, but more content is needed.

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 creation tool with nested objects and no output schema or annotations, the description is insufficient. It does not explain return values, error handling, or limitations, leaving the agent with incomplete context for invocation.

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 fully documents all three parameters. The description adds no additional meaning or context beyond the schema, resulting in a 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?

The description clearly states 'Create multiple ad group-level negative keywords,' specifying the action (create), resource (ad group-level negative keywords), and scale (multiple). This distinguishes from sibling tools like ebay_create_ad_group_negative_keyword (single) and bulk update/delete tools, though it does not explicitly name alternatives.

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 the single creation tool or other bulk operations. There is no mention of prerequisites, like required campaign state, or when bulk creation is preferable to sequential creation.

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