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 says 'Confirm' without indicating whether the action is destructive, requires specific permissions, or what side effects occur. This is a significant gap for a tool that likely finalizes a draft.

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 clearly states the tool's purpose. It is appropriately brief for a simple confirmation action, though it could benefit from 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?

For a tool with two required parameters and no output schema, the description is incomplete. It does not explain the workflow context (e.g., that it confirms a draft created by a prepare tool), the expected state of the draft, or any side effects. An agent would struggle to know when and how to invoke it correctly.

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?

The description does not explain either parameter. While the schema documents customer_id, draft_id has no description and the schema coverage is only 50%. The description adds no meaning to the parameters, leaving draft_id ambiguous and unsupported.

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 a specific action (confirm) on a specific resource (a guided quick-create draft). It distinguishes from sibling tools like google_ads_quick_create_prepare by using 'confirm' as the verb, making the tool's role in the prepare/confirm workflow evident.

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. It does not mention that it should follow a prepare step, nor does it reference any alternatives. The workflow context is entirely absent, leaving the agent to infer when confirmation is appropriate.

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