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

Annotations already declare destructiveHint=true, idempotentHint=true, and non-read-only, so the safety profile is covered. The description does add genuinely new context by saying the copy runs as a queued task, but it does not explain what is destroyed, what happens on a digest mismatch, or how to follow the queued task afterward.

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?

Two sentences with the action and preconditions front-loaded and no filler. Slight compression cost: the required-parameter clause is tacked on rather than integrated, but nothing is wasted.

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?

An output schema exists, so return values need not be documented, and annotations cover the safety profile. Still missing for a destructive, asynchronous operation: why the count parameters exist, the meaning of the digest guard, and that the queued task can be tracked through the tasks_* siblings.

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 0%, so the description must carry the burden of parameter meaning and it does not. It names approval_ref and expected_plan_digest but explains neither their purpose nor the approval_ref/batch_ prefix formats, and it says nothing about ad_count, adset_count, or campaign_count, which are otherwise entirely opaque.

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 and resource: it copies an approved group of Meta ads as a queued task, which distinguishes it from the many single-object confirm tools in the sibling list. The word 'grouped' separates it from operations_confirm_ad_copy, but that contrast is only implicit rather than called out.

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?

'Run the change the user just confirmed in this conversation' implies the tool belongs after an approval step, and the required parameters reinforce that. However, it never names the prepare/deny counterpart or says what to do when no approval exists, so the routing to alternatives is left to inference.

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