okx_set_settle_currency

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

No annotations are provided. The description does not disclose behavioral traits such as whether this action is destructive, requires admin privileges, or has side effects. The prerequisite hint is minimal.

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 short but wastes space on a prerequisite note that is not fully explained. It lacks clarity and does not efficiently convey the tool's purpose.

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 no annotations and no output schema, the description should compensate by explaining the behavior and context. It fails to do so, leaving the agent with insufficient information to correctly invoke the tool.

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 coverage is 100% with a single parameter 'ccy' described as 'settlement currency, e.g., USDT. Required.' The description adds no additional meaning beyond the schema, so a baseline of 3 is appropriate.

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 is in Chinese and does not explicitly state the tool's action. It only provides a category and a prerequisite, leaving the main purpose (setting settlement currency) implied from the parameter name 'ccy'. This is vague and requires prior knowledge.

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 mentions calling 'agent_catalog' first, hinting at a prerequisite, but provides no guidance on when to use this tool vs alternatives or what context it serves. Sibling tools are numerous but not differentiated.

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