getUserSettingConfig

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

Annotations already carry the safety profile (readOnlyHint=true) and are not contradicted by the description. The description adds useful context beyond the annotations: authentication is required and results are scoped to the authenticated user. It does not cover failure modes, permission errors, or response structure, so the added behavioral value is modest.

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: the core purpose and the no-parameters constraint appear immediately, with a short notes block after. The only minor blemish is redundancy between 'Query the user account setting configuration' and 'Returns the current account configuration,' which restate the same object.

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 parameterless, read-only tool whose safety profile is already in annotations, the description covers purpose, content areas, authentication, and user scoping. The absence of an output schema is partially compensated by naming margin mode, account mode, and spot hedging. A more precise response or error-behavior description would be the only remaining gap.

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 the empty input schema with 100% coverage already documents this fully, so the baseline of 4 applies. The description reinforces the point by explicitly stating 'no query parameters,' which helps prevent an agent from fabricating arguments.

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?

States a specific verb ('Query') and resource ('user account setting configuration'), and enumerates the contents (margin mode, account mode, spot hedging status, other account-level settings). This clearly distinguishes it from narrow siblings like getMmpState and from mutating siblings like setMarginMode and setHedgingMode.

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 notes that the endpoint 'requires authentication but no query parameters' give useful call constraints, and the read-only scope implies when an agent should call it. However, it never names alternatives or states when not to use it — for example, it does not route modifications to setMarginMode or setHedgingMode, leaving differentiation entirely to the agent.

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