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

The annotations already establish that this is a safe, read-only, closed-world operation. The description adds useful context that results are scoped to the trainer's app and sorted newest first, but it does not disclose pagination, read/unread inclusion, or result limits.

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?

It is a single compact sentence with no wasted wording. However, it is a noun phrase rather than a verb-led statement, so it is slightly less front-loaded than an action-oriented description.

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 description covers scope and ordering for a simple no-parameter read tool. With no output schema, it could still say more about what notifications include, whether read and unread are mixed, or whether results are paginated.

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 tool has zero parameters, so there are no parameter semantics to document. The description appropriately avoids inventing parameter details, matching the baseline for a no-parameter tool.

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 identifies the resource precisely as the trainer's app notifications and adds the ordering (newest first). The tool name supplies the list verb, but the description does not explicitly differentiate this from notification-marking siblings such as mark_notification_read or mark_notifications_read.

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?

It implies this is how to retrieve notifications, but gives no explicit when-to-use or when-not-to-use guidance. It also does not mention alternatives like mark_notification_read, mark_notifications_read, or other notice-related tools.

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