BinanceSubAccountGetUniversalTransferHistory

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

With no annotations, the description carries the full behavioral burden, and it only implies read-only behavior through the verb 'Query.' It says nothing about authentication scope, rate limits, pagination defaults, time-window constraints, or what happens with no matching transfers. For a 7-parameter history endpoint with zero annotation coverage, this is a significant gap.

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 front-loaded sentence with no wasted words. It is efficient but so terse that the concision comes at the cost of necessary context rather than through tight editing.

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 seven optional parameters, no annotations, no output schema, and a domain with closely named sibling endpoints, the description is not complete enough. An agent still needs to know how this differs from BinanceSubAccountGetTransferHistory, what permissions are required, and what the result set represents. The schema fills in parameter names but not the selection 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 coverage is 100%, so every parameter including page, limit, startTime, endTime, fromEmail, and toEmail is already documented in the schema. The description adds no additional meaning about parameter interaction, such as whether fromEmail/toEmail are required together or how startTime and endTime combine. Baseline 3 is appropriate when the schema does the heavy lifting.

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 names a specific verb and resource: 'Query universal transfer history for sub-accounts.' An agent can tell this is a read operation over sub-account universal transfer records. However, it does not differentiate from sibling endpoints such as BinanceSubAccountGetTransferHistory or BinanceWalletQueryUserUniversalTransferHistory, so the purpose is clear but not uniquely scoped.

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?

There is no when-to-use or when-not-to-use guidance. The description does not mention alternatives like BinanceSubAccountGetTransferHistory or BinanceWalletQueryUserUniversalTransferHistory, nor does it state prerequisites such as needing a master-account API key. Usage must be inferred entirely from the name.

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