getSpotMarginTradeCoinState

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

With no annotations, the description must convey behavioral traits. It states it is a read operation and specifies the unified account requirement. However, it does not disclose potential rate limits, authentication needs, or the structure of the returned data.

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 very concise: two sentences with a clear bullet point. Every sentence adds value with no redundant information.

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?

Given the simple input schema and no output schema, the description covers the core behavior and constraints. However, it omits details about the return format or error scenarios, which would be helpful for an AI agent.

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 schema has 0% coverage, so the description compensates by explaining that omitting currency returns all coin states. This adds meaning beyond the raw schema, but it does not specify valid currency formats or examples.

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 clearly states the tool retrieves spot margin leverage information for cryptocurrencies, with a specific verb and resource. It also notes the unified account requirement and the behavior when currency is omitted. However, it does not explicitly differentiate from sibling tools like getSpotMarginTradeState.

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 context that the tool is for unified accounts only and explains the optional currency parameter's effect. However, it lacks explicit guidance on when not to use this tool or mention alternatives for non-unified account scenarios.

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