createAdmobAdUnitMapping

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

With no annotations, the description fails to disclose behavioral traits. It states 'create' implying mutation, but doesn't address permissions, reversibility, side effects, or whether existing mappings are affected. This is a significant gap for a write operation.

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 redundancy. However, it is overly terse and could benefit from more context without hurting conciseness.

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 no output schema, 4 parameters, and no annotations, the description is incomplete. It doesn't explain return behavior, success/failure indicators, or any constraints (e.g., uniqueness of mappings). The tool is a creation operation but lacks sufficient guidance for correct 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 baseline is 3. The description adds no additional meaning about parameters beyond what the schema already provides (e.g., adUnitName, adapterId). It doesn't clarify how parameter values interact or what constitutes valid configurations.

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 identifies the verb 'create' and resource 'ad unit mapping'. It specifies 'for a specific ad unit', which helps distinguish from the sibling batchCreateAdmobAdUnitMappings. However, it doesn't elaborate on what an ad unit mapping is or how it relates to other concepts.

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 provides no guidance on when to use this tool vs alternatives (e.g., batchCreateAdmobAdUnitMappings). No prerequisites, context, or conditions for use are mentioned.

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