BinanceWalletEnableFastWithdrawSwitch

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

With no annotations, the description carries full burden for behavioral disclosure. It states the action but does not explain side effects, such as whether enabling the switch changes withdrawal review processes, requires special permissions, or is reversible. There is no mention of risk or impact, making the behavior opaque for a mutating operation.

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 very short at four words, which is efficient, but it lacks a sentence structure and reads as a fragment. It earns no extra credit for details, and while there is zero waste, the brevity borders on under-specification rather than deliberate 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 simple tool with one optional parameter and no output schema, the description might be adequate if it explained the switch's effect, but it doesn't. The tool is likely part of a wallet management API, and the description provides no context about what the switch does, when to use it, or what happens after enabling. The sibling tool names hint at a toggle pair, but the description itself is incomplete.

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 schema has 100% coverage for the single parameter recvWindow, which is described as a number with a max constraint. The description does not mention the parameter at all, but since the schema is fully self-explanatory and there is only one parameter, the baseline of 3 is appropriate; the parameter's purpose (receive window for request timing) is standard and not clarified further by the description.

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 'Enable fast withdraw switch' clearly identifies the action (enable) and the resource (fast withdraw switch), which is distinct from the sibling tool 'DisableFastWithdrawSwitch'. However, it lacks specificity about the effect or scope of the switch, and without context it reads as a terse fragment rather than a complete sentence.

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?

No guidance is provided on when to use this tool versus the disable counterpart or any other sibling. The description gives no context about prerequisites, timing, or intended use case, leaving the agent to infer usage from the name alone.

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