ebay_create_targeting

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

Minimal description with no annotations. Does not disclose if this operation is idempotent, what happens on conflict, required permissions, or side effects like overwriting existing targeting.

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, concise sentence with no extra words. It is well-structured and readable.

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?

Despite low complexity (2 params), the description lacks explanation of return value or success confirmation. No output schema exists, so the description should hint at what the response contains.

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% with basic descriptions for both parameters. The tool's description adds no additional meaning beyond what is in the schema. The 'targeting' object type is ambiguous.

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 'Create targeting configuration for a campaign' clearly states the action and resource, but does not differentiate from sibling tools like ebay_update_targeting. It is specific and uses a verb+resource structure.

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 on when to use this tool versus alternatives or prerequisites. Lacks context such as whether a campaign must already exist or if targeting can be modified later.

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