okx_predictions_place_order

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

No annotations are provided, and the description gives only a '[L:WRITE]' tag indicating a write operation, which is already obvious from the tool name. It does not disclose behavioral traits such as authentication requirements, rate limits, order lifecycles, or side effects beyond the basic write nature.

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 concise but at the cost of informativeness. It consists of a single line with tags and a prerequisite, lacking structure or clear separation of information. Conciseness should not sacrifice essential content.

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 tool's complexity (5 parameters, write operation, many siblings) and absent output schema, the description is severely incomplete. It does not explain what happens after placing an order, return values, or how the order is managed. This is inadequate for an agent to use effectively.

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 input schema provides full coverage of all 5 parameters with descriptions, so the description is not required to add parameter details. However, the description adds no additional semantic context or examples beyond the schema. Baseline 3 is appropriate given high schema coverage.

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 only provides category tags and a prerequisite instruction ('请先调用 agent_catalog'), but does not explicitly state what the tool does (e.g., places an order for prediction markets). The tool name implies placement, but the description is vague and lacks a clear verb+resource statement.

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 a prerequisite (calling agent_catalog), which provides some guidance, but there is no information on when to use this tool versus alternatives like okx_event_place_order or other order placement tools. It fails to differentiate usage context.

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