get_user_profile_settings

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and scope are covered elsewhere. The description adds only that the data is scoped to 'the current user' (no user parameter); the note that '参数和日期限制沿用官方接口' is uninformative for a zero-parameter tool and adds no real behavioral context such as what settings are returned.

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 content is duplicated bilingually — '个人资料设置' and 'Return the current user's profile settings' say the same thing — and the '与官方客户端一一对应 / 参数和日期限制沿用官方接口' sentences are meta-filler that doesn't help an agent decide or invoke.

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 no-arg read with no output schema, the description is minimally adequate but never indicates which profile settings come back (units, fields, whether it includes goals/devices), so an agent cannot anticipate the response shape.

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 takes zero parameters, so the baseline is 4. The mention of parameters and date restrictions 'following the official interface' is mildly confusing given the empty schema, but it does no harm.

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 English sentence states a specific verb and resource: return the current user's profile settings. That is clearly distinct in kind from the sibling tools (daily stress, steps, sleep, etc.), though the description never names a sibling or explicitly contrasts itself with them.

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?

There is no statement of when to use this tool vs. alternatives, nor any prerequisites or exclusions. The only contextual hint is the meta note that it maps one-to-one to the official client's get_user_profile_settings, which tells the agent nothing about selection.

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