send_target_to_review

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

Annotations already signal this is a non-read, non-idempotent, non-destructive operation. The description adds useful context by noting that submissions/resubmissions are possible and that a non-zero budget is required, which is not present in the annotations. It provides a meaningful behavioral precondition beyond the structured data.

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 that leads with the primary action and then adds the key prerequisite. There is no redundant phrasing or filler, and the resubmission behavior is efficiently folded into the opening clause.

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?

For a tool with one required parameter and a clear workflow step, the description captures the action, resubmission possibility, and a critical precondition. The output schema exists, so return-value details are not required here. The main gap is the lack of explicit guidance about how this step relates to sibling tools, but the low complexity keeps this from being a serious deficiency.

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 description coverage is 0% and the description does not explain the ad_id parameter at all. The schema only provides the property name and a generic title 'Ad Id,' so the description fails to compensate for the low coverage by clarifying which ad or targeting entity the ID refers to. The single parameter is self-explanatory from its name, but the description itself adds no parameter-level meaning.

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 opens with a clear action verb and resource: 'Submit (or resubmit) targeting for review.' It clearly conveys the operation and the review workflow step, and distinguishes itself from actions like launch_ad or create_ad through the 'review' framing. However, it does not explicitly differentiate from sibling tools or mention that ad_id is the target identifier.

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 implies the tool should be used when targeting needs to be submitted or resubmitted for review, and it gives a concrete precondition: 'Requires a non-zero budget.' It does not state when not to use this tool or point to alternatives like launch_ad or preview_ad, leaving the usage context implicit rather than explicit.

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