okx_predictions_cancel_order

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

No annotations are provided, so the description must entirely convey behavioral traits. It fails to disclose any details such as required permissions, idempotency, side effects, or return behavior of the cancellation. The tag '[L:WRITE]' hints at mutation but provides no substantive behavioral insight.

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?

While the description is very short, it lacks a structured explanation of the tool's function. It is more underspecified than concise, with essential information missing. The tag and prerequisite are presented without clear organization or complete sentences.

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 mutation tool with no output schema, the description must provide sufficient context about cancellation behavior, state changes, and response format. It completely fails to do so, leaving the agent with insufficient information to use the tool correctly.

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 one parameter 'orderId' described as '订单ID'. The description adds no additional meaning beyond the schema, which already defines the parameter. Baseline 3 is appropriate as the description does not enhance parameter understanding.

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 contains only a tag '[L:WRITE] CAT:[预测]' and an instruction to call agent_catalog first. It does not explicitly state that this tool cancels an order, relying solely on the tool name to convey purpose. The purpose is vague and not clearly articulated.

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 instruction '请先调用 agent_catalog' provides a clear prerequisite, indicating that the agent should first retrieve the catalog before using this tool. However, it offers no guidance on when to use this tool over alternatives like okx_predictions_cancel_all or okx_event_cancel_order, leaving the agent to infer usage context.

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