remind_get_notification_settings

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

Annotations already establish that this is a read-only, idempotent operation, so the bar is lower. The description still adds meaningful behavior beyond annotations by explaining the `canManage*` flags and the subscriber-account limitation on changes, which is real permission context an agent needs.

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 tightly written sentences that front-load the resource and its contents, then add the permission caveat. Every clause is informative and nothing is repeated from structured fields.

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?

With no output schema but zero parameters, the description carries the full burden of explaining the return shape, and it does so by naming the preference categories and device types returned. The permission semantics round out what an agent needs to interpret the response correctly.

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 takes zero parameters, so the baseline is 4. There are no parameter names or formats to clarify, and the description correctly does not waste space on non-existent inputs.

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 (Get) and resource (notification settings), and enumerates the exact sub-settings returned (reply/announcement-copy/incoming-call preferences, delivery devices). It does not explicitly contrast itself with the sibling `remind_set_notification_devices`, so it stops short of the sibling-differentiation bar for a 5.

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 never states when to call this tool versus alternatives such as `remind_set_notification_devices`, nor does it give any prerequisite or timing guidance. Usage is only implied by the verb 'Get', which is not enough for a 3.

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