BinanceSubscribeSolStaking

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

With no annotations, the description carries the full burden. It discloses the core behavior (staking SOL, receiving BNSOL) and the response content (BNSOL amount and exchange rate). However, it does not mention that the user's SOL balance will be deducted, whether staking is reversible, or any other side effects or prerequisites beyond the amount.

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 two sentences and gets to the point quickly. However, the phrase 'Subscribe SOL Staking API' at the beginning is slightly redundant with the tool name, but it does not detract significantly from clarity.

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 low complexity (2 parameters, no output schema), the description covers the essential aspects: what it does, the required parameter, and the response's key fields. It would benefit from clarifying that this is a one-time staking action (not a recurring subscription) and that SOL is deducted from the account, but overall it is reasonably complete for an agent to invoke correctly.

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%, so the schema already explains both 'amount' and 'recvWindow'. The description only reiterates that the amount is in SOL and required, adding no additional meaning beyond what the schema provides. 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 clearly states the function: 'stake SOL and receive BNSOL in return' with a specific verb and resource. It distinguishes itself from sibling tools like BinanceSubscribeEthStaking and BinanceRedeemSol by explicitly naming SOL staking and the BNSOL output.

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 implies the tool should be used when a user wants to stake SOL, and it explains the required input (amount of SOL). However, it does not mention alternatives or exclusions (e.g., 'for redeeming BNSOL, use BinanceRedeemSol'), so it lacks explicit when-not-to-use guidance.

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