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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true. The description simply says 'Get', which aligns with read-only behavior but adds no additional behavioral context (e.g., response format, error conditions, or any side effects). Since annotations cover safety, the description meets the baseline without contradiction.

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 two sentences: the primary purpose and the HTTP endpoint. Both are necessary and there is zero fluff. It is front-loaded with the action and resource, making it immediately clear to an agent.

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: no parameters, read-only, and an output schema exists (indicated by 'has output schema: true'). The description does not need to explain return values. The only minor gap is a lack of mention of what settings are included, but for a straightforward GET it is sufficiently complete.

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 schema coverage is 100% (empty schema). Per the baseline for 0 params, the description does not need to explain parameters. The description adds no parameter-specific information, which is appropriate for a no-parameter GET request.

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 states a clear verb ('Get') and resource ('email notification settings'). It distinguishes from sibling tools by specifying 'email' as the channel, though it does not explicitly name the alternatives. The name already carries the differentiation, so the description is adequate.

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 gives no explicit when-to-use guidance or exclusions. It implies a retrieval operation, and the name suggests it is specific to email notifications. Sibling tools for other channels (discord, gotify, etc.) are not referenced, but the context makes the intent clear. Some guidance on when to choose this over other notification settings tools would improve it.

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