get_user_by_user_id_settings_permissions

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 the HTTP method and path but does not disclose authentication requirements, error behavior, or response characteristics. With annotations present, this is acceptable but not rich.

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 compact and front-loaded with the core purpose, followed by the endpoint and parameter note. No filler or redundant detail appears.

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 one-parameter read-only GET tool, the combination of description, annotations, and output schema covers the essential invocation details. It lacks explicit mention of authorization or how this differs from permission-related sibling tools, but the low complexity and strong annotations reduce the burden on the description.

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?

There is only one parameter and the schema coverage is 0%, so the description must compensate. It states 'user_id: Path parameter,' adding the parameter's location, but it does not explain the meaning, format, or constraints beyond the schema's type and required flag. This is minimally adequate.

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 and resource: 'Get permission settings for a user.' This distinguishes it from sibling create/update/delete tools and other user settings getters like get_user_by_user_id_settings_main or settings_password, though it does not explicitly call out those siblings.

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 is given about when to use this tool versus alternatives such as create_user_by_user_id_settings_permissions or other user settings getters. The description simply restates the operation and endpoint, leaving the agent to infer the appropriate context.

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