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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only labels the operation as 'confirm' without stating whether this executes the unlink, whether it is destructive or reversible, whether a prepared draft is required, or what side effects occur.

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 one short, front-loaded sentence with no filler, which is structurally easy to parse. However, it is under-specified rather than appropriately complete, so brevity is not a fully earned strength.

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 confirm-style mutation tool with no annotations and no output schema, the description is too thin. It does not mention return values, task/receipt behavior, or the expected prepare-before-confirm sequence, leaving an agent without enough information to call it confidently.

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 50%, with only customer_id documented. The description adds little semantic value for draft_id: the word 'draft' hints at its role, but does not explain how to obtain the draft_id, its format, or how it relates to a prior prepare call.

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 states a clear action ('Confirm') and a resource ('an asset-unlink draft'), and the word 'draft' distinguishes it from the prepare and asset-link siblings. However, it does not explain what 'confirm' actually accomplishes, so it is clear but slightly underspecified.

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?

There is no guidance on when to use this tool versus google_ads_asset_unlink_prepare, google_ads_asset_link_confirm, or other confirm tools. The draft wording implies a prior prepare step, but the description does not state the prerequisite workflow or any exclusions.

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