registerBinanceGetEthStakingHistory

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

With no annotations, the description carries the transparency burden. It clearly indicates a read-only operation via 'retrieve' and lists sample response fields. However, it omits pagination behavior, time-range semantics, and any authorization requirements.

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 a single sentence that is front-loaded and free of unnecessary content. It has minor redundancy with the tool name ('Get ETH Staking History' vs 'historical ETH staking records'), but remains efficient.

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?

The description partially fills the missing output-schema gap by naming some returned fields. However, it does not mention pagination via size/current or the time-range filter options, which are relevant for an agent to use the tool effectively.

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 already provides 100% description coverage for all five parameters, so the baseline is 3. The description does not add parameter-specific details beyond the schema, but implies time-based filtering consistent with startTime/endTime.

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 a specific verb ('retrieve') with a specific resource ('historical ETH staking records') and lists key return fields. It does not explicitly distinguish from sibling tools like BinanceGetEthRedemptionHistory, but the resource scope is clear enough.

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 usage when historical ETH staking records are needed, but provides no explicit guidance on when to prefer this tool over alternatives such as BinanceEthStakingAccount or BinanceGetEthRedemptionHistory, and no exclusions or prerequisites.

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