okx_predictions_heartbeat

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

No annotations are provided, and the description only indicates it is a read operation. There is no disclosure of behavioral traits such as whether it performs network calls, changes state, or has rate limits. The minimal '[L:READ]' label is insufficient.

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, consisting of a single line with brackets and Chinese. While it is short, it sacrifices clarity for brevity and relies on coded labels that may confuse the agent.

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 has no parameters, no output schema, and a simple intended function, the description should still clearly state its purpose and behavior. It fails to do so, leaving the agent without sufficient context to decide when and why to use it.

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 tool has zero parameters, so schema coverage is 100% by default. The description adds no parameter information, but per the guidelines, a baseline of 4 is appropriate for tools with no parameters. The instruction to call agent_catalog is unrelated to parameters.

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 uses cryptic labels '[L:READ]' and 'CAT:[预测]' but fails to state that this tool checks the heartbeat status of the predictions service. The purpose is vague and does not clearly distinguish from sibling prediction tools.

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 advises to call 'agent_catalog' first, implying a prerequisite, but provides no guidance on when to use this tool versus alternatives like 'okx_predictions_list_events' or 'okx_predictions_get_event'. Usage context is unclear.

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