okx_purchase_sol_staking

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention that the tool creates a staking purchase, requires permission, or any side effects. It is essentially empty of behavioral context.

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 (one line), but this is under-specification rather than conciseness. It fails to provide necessary information, making it ineffective.

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 is an action (purchase staking) with one required parameter and no output schema or annotations, the description should at least clarify the operation. It is severely incomplete, offering no useful context.

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?

Schema description coverage is 100% with one parameter ('amt') already described as '质押数量（SOL）。必填'. The tool description adds no additional meaning beyond this, so baseline 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 does not state what the tool does. It only contains a Chinese instruction '请先调用 agent_catalog' (please call agent_catalog first) and a category marker. The tool name suggests purchasing SOL staking, but the description fails to confirm or describe the action.

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 guidance is provided on when to use this tool versus alternatives like okx_stake_eth or okx_redeem_sol_staking. The only instruction is to call agent_catalog first, which is a prerequisite but not a usage guideline.

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