android_notification_dismiss

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

The annotations already flag destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds the 'active' precondition and the reliance on a key, but does not disclose additional behavioral details such as permission requirements or what happens if the key is invalid.

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?

The description is a single, front-loaded sentence with no filler. It directly states the action, target, and required parameter, making it efficient and easy to parse.

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 one-parameter tool, the core mechanics are present, and the destructive annotation covers the mutation risk. However, the description omits how the notification key is obtained, whether special permissions are required, and what the tool returns or does on failure. Given no output schema or parameter descriptions, this leaves some uncertainty.

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 semantic load for the key parameter. Saying 'by key' identifies the parameter but does not explain what a notification key is, where to obtain one, or how it should be formatted. This is minimal compensation for an undocumented schema.

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 uses a specific verb, 'Dismiss', names the resource, 'active notification', and specifies the mechanism, 'by key'. This clearly distinguishes it from sibling tools like android_notification_open and android_notification_reply.

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 intended use is implied by the verb and resource: use this when you want to dismiss an active notification. However, the description does not explicitly state when not to use it or mention alternatives such as opening or replying to a notification.

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