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

Annotations already mark this as a non-read-only, non-destructive, closed-world operation, so safety is partly covered. Beyond that the description adds nothing: it does not say whether confirmation executes the draft, whether the draft is consumed, whether the call is idempotent, 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?

A single short, front-loaded sentence with no filler, so it is not bloated. It is, however, too thin to carry the informational load for a mutation tool, so it lands at minimum-viable rather than exemplary.

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 non-read-only confirmation step with no output schema and two required parameters, the definition omits prerequisites, side effects, and return behavior. Annotations cover the safety profile but the operational picture an agent needs is missing.

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 only 33% (only customer_id is documented), so the description should compensate but does not. The word "draft" loosely hints at the required draft_id, but nothing explains draft_id format or the connection_context pattern parameter.

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 gives a verb ("Confirm") and a resource ("guided quick-create draft"), so the basic action is inferable. However, it never states what entity the draft actually creates or names its counterpart sibling google_ads_quick_create_prepare, leaving the agent to guess at the scope of the confirmation.

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 when-to-use guidance, no prerequisite that a draft must first be produced by google_ads_quick_create_prepare, and no statement of what happens after confirmation. The prepare/confirm pattern is only implied by the tool name, not the description.

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