list_settings_notifications_lunasea

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description's GET endpoint reinforces the read-only nature but adds little beyond the annotation. No contradiction; it just does not disclose anything substantive beyond what annotations provide.

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 lines with zero waste: the purpose is front-loaded and the HTTP endpoint adds precise, actionable information. Every element earns its place.

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?

For a simple 0-parameter, read-only GET with an output schema, the description plus annotations are largely sufficient — safety is covered by annotations, return shape by the output schema, and purpose by the description. The notable gap is the lack of differentiation among the cluster of near-identical notification-setting list tools.

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 0 parameters with 100% schema coverage, so there is nothing for the description to clarify. Baseline for 0-parameter tools is 4, and the description appropriately omits parameter detail.

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?

"Get LunaSea notification settings" states a clear verb (Get) and resource, and the HTTP endpoint disambiguates the exact operation. However, it is essentially a readable paraphrase of the tool name and does no explicit differentiation work against the many sibling notification-settings tools (pushbullet, discord, telegram, etc.), relying on the resource name alone.

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 siblings such as list_settings_notifications_pushbullet, nor the write counterpart create_settings_notifications_lunasea. The readOnlyHint annotation implies read usage, but the description itself gives no when-to-use or when-not-to-use context.

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