get_user_by_user_id_settings_notifications

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds no behavioral context beyond the annotations, such as return format, error behavior, or auth requirements. It merely states 'Get' and provides the endpoint, which is fully consistent with the annotations but adds no new transparency.

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 extremely concise: one purpose sentence, the endpoint, and a single parameter note. It is front-loaded with the core purpose and contains no fluff or filler. 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?

The tool has an output schema, so return values are covered elsewhere. The description clearly states what the tool does and the required parameter. The annotations handle safety. The only minor gap is the lack of any note about which notification channels are included, but this is not necessary given the output schema and the simplicity of the operation.

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%, so the description must compensate. It does identify user_id as a path parameter, which is slightly beyond the schema (which only states type: number). However, it does not explain what user_id refers to or any constraints, leaving the meaning to be inferred from the parameter name. This is minimal compensation, but sufficient for a single, self-explanatory parameter.

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 specific verb and resource: 'Get notification settings for a user.' It clearly identifies the tool's purpose and distinguishes it from sibling tools like get_user_by_user_id_settings_main or get_user_by_user_id_settings_permissions by explicitly naming 'notification settings.' The included endpoint further reinforces this.

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 a clear context for when to use the tool (to fetch a user's notification settings), but it does not provide any exclusion or comparison with alternatives. Given the large sibling family of user settings tools, an agent would need to infer the correct choice from the name alone, as no explicit guidance is offered.

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