acknowledge_notification

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the mutation and repeat-call safety profile is covered by structured data. The description adds the concrete effect (repetitions and audio cease) but doesn't say whether the notification stays in the list, is dismissed, or what happens on a second call. With annotations present, this is an acceptable but thin addition.

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 short sentences, effect first and exclusion second. No filler, no restatement of the tool name, and the most decision-relevant fact is front-loaded.

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 single-parameter, non-destructive, idempotent operation with annotations covering the safety profile and no output schema, the description covers the essentials. The remaining hole is post-call state — whether the notification is removed or merely silenced — which matters for follow-up calls.

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?

With one parameter at 0% schema coverage, the description must carry the semantics, and it only contributes 'one notification' — confirming the id targets a single item. It never says where the id comes from (presumably list_notifications) or what format it takes, so an agent still has to infer the identifier source.

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 effect: 'Stop repetitions and audio for one notification.' The scope is bounded to a single notification, so an agent knows this is not a bulk operation. It doesn't name a sibling tool, but the second sentence separates the action from responding-to or approving on the notification's behalf.

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?

'Does not answer a question or grant permission' is a genuine when-not rule that disambiguates the overloaded verb 'acknowledge' — an agent won't mistake this for approving a request. The gap is that it doesn't say which tool to use instead when the intent is to respond or approve.

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