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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered elsewhere. The description adds nothing about what the response contains, whether the record is workspace-scoped, or what happens when the id is absent (it doesn't mention 404 behavior or auth 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?

The single meaningful sentence is duplicated verbatim, and the operation-ID pointer is noise for an agent selecting a tool. It's short, but the shortness comes from under-specification rather than efficiency.

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?

There is no output schema, no parameter documentation, and no behavioral context, so an agent has essentially nothing beyond the endpoint path and the annotations. For a nested-object, 0%-coverage tool this is completely inadequate.

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% and the description provides no parameter information at all. With two parameters — a nested required 'params.id' (string, 1-2000 chars) and an untyped 'query' object — the description needed to explain the id format and what query filters are supported, and it does neither.

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 only restates the tool name and HTTP path ('GET /api/notification-settings/:id') twice, which is tautological rather than explanatory. It does not clarify what a 'notification setting' contains or how this record differs from the sibling get_notification_settings and get_notification_settings_preview endpoints.

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?

No guidance on when to call this versus siblings such as get_notification_settings_f43b492a9011960665a90046, get_notification_settings_preview, or get_notifications_preferences. The only pointer is to describe_operation for request schemas, which is a schema hint, not usage guidance.

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