get_email_notification_settings

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

The annotations already declare readOnlyHint=true and destructiveHint=false, and the description merely restates the read nature ('Get') without adding any behavioral context such as return format, permissions, or side effects. It adds no value beyond the structured metadata and does not contradict the annotations.

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 wasted words, appropriately sized for a zero-parameter getter. However, it is so minimal that it borders on under-specification, offering no additional context.

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?

Given the tool's simplicity (read-only, zero parameters) and the presence of an output schema, the description is sufficient for an agent to select it correctly. The sibling list provides a clear update counterpart, and annotations cover the safety profile, though the description could mention what settings are included.

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 and 100% schema coverage, so the baseline is 4. There is nothing for the description to explain about parameters, and it correctly does not invent any.

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 ('Get') and a specific resource ('email notification settings'), making the tool's function clear. It distinguishes naturally from the sibling update_email_notification_settings tool via the get/update contrast, though it essentially restates the tool name without adding scope or detail.

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 provides no guidance on when to use this tool versus alternatives, no mention of update_email_notification_settings as the write counterpart, and no exclusions or prerequisites. An agent receives zero contextual direction beyond the tool's name.

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