okx_get_lending_rate_history

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

No annotations provided. The description includes [L:READ] hinting at read-only behavior but not formally. It does not disclose return format, side effects, rate limits, or data scope. The dependency on agent_catalog is mentioned but not explained.

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 very short but includes non-essential tags like [L:READ] and CAT:[金融] that could be inferred from context. The instruction to call agent_catalog adds necessary but clunky info. It could be more streamlined.

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 output schema and no annotations, the description should explain what the tool returns and any prerequisites. It only states the basic action and a vague dependency, leaving the agent uncertain about the response format and proper usage sequence.

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?

Input schema has zero parameters, so no parameter description is needed. Baseline of 4 applies as the description does not need to add parameter info. The tool takes no arguments, making this dimension trivially satisfied.

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 tool name indicates 'get lending rate history' and description includes [L:READ] and CAT:[金融], suggesting read-only finance data. However, the instruction '→ 请先调用 agent_catalog' muddles the purpose, implying a prerequisite. It does not clearly distinguish from siblings like okx_get_lending_rate_summary.

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?

No explicit guidance on when to use this tool vs alternatives. The instruction to call agent_catalog first is a hint but not a clear usage guideline, leaving the agent to infer context.

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