BinanceSubAccountGetStatus

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

No annotations are supplied, so the description carries the full behavioral burden. It implies a read operation via "Get" and lists what the status covers, but says nothing about permissions (parent-account API key), rate-limit weight, or whether omitting the sub-account identifier returns all sub-accounts or errors.

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?

A single tight sentence with the core purpose front-loaded and no filler. It is appropriately sized for the amount of information conveyed, though that brevity contributes to the behavioral gaps noted elsewhere.

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 two-optional-parameter read tool with no output schema, the core is covered, and the return contents are sketched (margin/futures enable flags). It stops short of stating the default behavior when no email is given or what other fields the status payload contains.

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% and both parameters are documented in the schema (email as optional, recvWindow bounded to 60000). The description adds nothing about the parameters beyond what the schema already states, so the baseline of 3 applies.

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 states a specific verb and resource ("Get sub-account status") and narrows the scope to margin/futures enable/disable flags, which separates it from siblings like GetMarginSummary or GetFuturesSummary. It does not name an explicit alternative, but the operation is unambiguous.

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 guidance. Given the dense cluster of near-identical siblings (BinanceSubAccountGetMarginSummary, BinanceSubAccountGetFuturesSummary, BinanceSubAccountGetAssets), the agent is left to infer which tool answers an "is margin enabled?" question.

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