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

With no annotations, the description carries full burden but only discloses the batch nature and item limit. It fails to mention whether the operation is idempotent, what happens on partial failure, or any authentication requirements, leaving significant behavioral unknowns.

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 efficient sentence that covers the core purpose and a key constraint, with no wasted words. It could be improved by adding a bit more context without becoming verbose.

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 batch creation with nested objects and no output schema, the description is insufficient. It does not explain return values, error handling, or provide enough context for an agent to understand the full lifecycle of the operation.

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 description adds no new parameter meaning beyond what the schema provides. The 'Max 100 items per call' is already reflected in the schema's maxItems constraint.

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 action 'batch create' and the resource 'ad unit mappings', giving a specific verb and target. It implicitly distinguishes from the sibling single-create tool, though it could be more explicit about the difference.

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?

The description only mentions a max 100 items per call limit, but provides no guidance on when to use this batch tool vs the single creation sibling, nor any prerequisites or context for use.

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