get_notifications

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It discloses the return format, which is useful, but doesn't explicitly state that the operation is read-only, nor does it mention potential side effects, permissions, or error conditions. The read-only nature is somewhat implicit from the verb 'get'.

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 that conveys the core purpose and return format without any wasted words. It is highly concise and well-structured.

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?

The tool is simple with one parameter, but the description omits any explanation of the required 'device' parameter. While the return format is given, the missing parameter guidance and lack of any usage conditions make the description incomplete for a correct invocation.

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 one required 'device' parameter with no description (0% schema coverage). The description does not mention this parameter, its purpose, or how to specify it. This is a significant gap because the device identifier is essential for using the tool correctly.

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 clearly states the tool's action ('Get active notifications') and the resource, with a specific return format ('JSON array of {package, title, text}'). This distinguishes it from sibling tools like open_notifications and clear_notifications, which are write or navigation actions.

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 description implies the tool is for reading notifications but provides no explicit guidance on when to use it versus alternatives like open_notifications or clear_notifications. No prerequisites or conditions are mentioned, so the usage context is only implied.

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