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

The description includes a '[L:READ]' tag indicating a read-only operation, but no other behavioral details are provided. The lack of annotations means the description carries the full burden, yet it does not disclose outcomes, side effects, or permissions beyond the read hint.

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 short but front-loads the READ tag and category. However, the prerequisite instruction is somewhat ambiguous, and the lack of a clear tool purpose makes the conciseness ineffective. It is minimally acceptable.

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 simple tool with one parameter and no output schema, the description should at least state what the tool returns (e.g., index components). It fails to do so, leaving the agent without a complete understanding of the tool's output and when to invoke 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 input schema covers 100% of parameters with a clear description for 'index' (name, example, required). The tool description adds no additional parameter information, so the baseline score of 3 is appropriate.

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 a label '[L:READ] CAT:[公共]' and a prerequisite instruction, but does not explicitly state what the tool does. It vaguely implies reading index components market data, but the purpose is unclear without additional context.

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 instructs to call 'agent_catalog' first, which provides a prerequisite. However, it offers no guidance on when to use this tool versus alternatives like 'okx_get_index_components', nor does it specify any conditions for usage.

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