subscribePublicTrade

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

No annotations are provided, and the description only states the purpose without any behavioral details. It does not disclose whether the subscription is persistent, how data is delivered, or any side effects. The agent receives zero behavioral insight beyond the name.

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 a single concise sentence in Chinese, with no fluff. It is front-loaded in the sense that it directly states the purpose. However, it could be structured more informatively.

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 (4 parameters, subscription behavior, no output schema, and no annotations), the description is severely incomplete. It lacks details on return values, usage patterns, and behavioral context, leaving the agent without enough information.

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 has 4 parameters with 0% description coverage, and the description does not add any meaning to parameters like symbol, category, messageCount, or timeoutMs. The agent gets no help understanding what these parameters do.

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 '订阅实时成交数据' clearly indicates the tool subscribes to real-time trade data. It is not a tautology and provides specific verb+resource. However, it does not differentiate from similar siblings like subscribeRfqPublicTrades or subscribeSpreadPublicTrade, lacking distinction.

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 no guidance on when to use this tool versus alternatives such as getPublicTrades or other subscribe tools. It does not specify context, prerequisites, or exclusions.

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