BinanceSubAccountDeleteApiKey

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

No annotations are supplied, so the description carries the full disclosure burden, yet it only restates the operation. It does not say the deletion is permanent, that any integration using the key stops working, or what permissions/parent-account authority are required. Only the bare fact of mutation is conveyed.

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 front-loaded sentence with no wasted wording. It is efficient, though its brevity stems partly from under-specification rather than disciplined 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?

This is a destructive mutation with no annotations and no output schema, so the description should explain the consequences of key revocation and any required authorization context. Instead it provides only one sentence, leaving the agent without enough behavioral context to call it safely.

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 subAccountId, subAccountApiKey and recvWindow are already documented in the schema. The description adds no meaning beyond that, which warrants the baseline 3 rather than more.

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 — 'Delete API key for a sub-account' — which is distinguishable from siblings such as BinanceSubAccountCreateApiKey and BinanceSubAccountGetApiKeyIpRestriction. It is clear but does not explicitly name those alternatives.

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 guidance on when to delete versus rotate or restrict a key, and no prerequisites or cautions about the operation being irreversible. The agent is left to infer usage entirely from the tool name.

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