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

Annotations already establish readOnly=false, destructive=false, and idempotent=false. The description adds only that dismissal happens 'without pausing', but does not explain what dismissal removes, whether it is reversible, or how confirm/dry_run parameters affect execution for this mutation.

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 front-loaded sentence with no wasted words. It is as concise as possible for what it chooses to say.

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 34-parameter mutation with zero schema descriptions, one sentence is drastically incomplete. Even though an output schema exists, the input surface and confirmation behavior are entirely undocumented.

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 schema has 34 parameters with 0% description coverage, and the description provides no parameter-level information. It does not explain key fields like action_id, rule_id, confirm, dry_run, or any of the campaign/metric/account fields.

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?

States a specific verb ('Dismiss') and resource ('a pending pause proposal'), and the phrase 'without pausing' distinguishes it from pause-related siblings. It does not explicitly name alternatives such as automate_confirm_action, so it stops short of full sibling differentiation.

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 mention of a 'pending pause proposal' implies the usage context, but there is no explicit guidance on when to use this instead of confirming, proposing, or ignoring a proposal. Alternatives and exclusions are left to inference.

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