registerBinanceGetBnsolRateHistory

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

No annotations are provided, so the description must fully convey behavioral details, but it only states the data content (APR and exchange rates). It does not disclose pagination behavior, time-range interpretation, or any operational constraints beyond what is superficially evident. The read-only nature is implied but not explicit.

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, well-structured sentence that front-loads the core purpose. It contains no filler or redundant phrasing, earning a maximum score for conciseness.

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 5-parameter read API with no output schema, the description gives a solid high-level overview but lacks details on response structure and operational semantics (e.g., how startTime/endTime affect the returned data). The schema compensates for parameters, but the description alone would not fully prepare an agent to interpret the results.

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 baseline is 3. The description does not add meaning beyond the schema; it only mentions the high-level output (APR, exchange rates) without linking to the size, current, or time parameters. The schema already documents each parameter adequately.

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 tool's function: retrieving historical BNSOL staking rate data including APR and SOL-to-BNSOL exchange rates. It uses a specific verb and resource, and is easily distinguished from sibling staking-related tools by naming the exact asset (BNSOL).

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 is for BNSOL rate history queries but provides no explicit guidance on when to use it versus alternatives, no prerequisites, and no exclusion criteria. Sibling tools with similar purposes (e.g., BinanceGetWbethRateHistory) are not referenced, leaving selection to inference.

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