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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the agent knows this confirms a mutating, destructive action. The description adds the useful detail that this commits a previously prepared draft (a two-phase confirmation), but says nothing about irreversibility, what happens to the draft after confirmation, or failure behavior. With annotations carrying the safety profile, this is adequate but thin.

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 four-word sentence with no filler, and the confirmation intent is front-loaded. However, it is under-specified rather than genuinely concise, so it does not earn a high score.

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 destructive, two-phase mutation tool with no output schema and only 33% parameter coverage, the description is far too sparse: it omits prerequisites, parameter meaning for draft_id, and any post-confirm behavioral expectations.

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 only 33% – only customer_id carries a description ('10-digit Google Ads customer id') while draft_id is undocumented. The description supplies no parameter meaning at all, so the critical draft_id argument is unexplained in both the schema and the description.

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 verb and resource ('Confirm a pause draft'), so the core action is identifiable, but it gives no scope detail and does not differentiate itself from the tightly related siblings google_ads_status_pause_prepare and google_ads_status_enable_confirm. An agent must infer the two-phase workflow from naming conventions alone.

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 explicit when-to-use guidance, no mention of the prerequisite that a draft must first be created via google_ads_status_pause_prepare, and no exclusions. The word 'draft' weakly implies a prior step, but nothing states it.

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