BinanceSubAccountUpdateIpRestriction

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 discloses almost nothing: not that status=2 clears restrictions, not that ipAddress is presumably mandatory when restricting, not the permission level or whether existing restricted IPs are overwritten. Only the word 'Update' signals a mutation.

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 zero filler; the verb and target come first. It is efficient, though the brevity borders on under-specification for a mutating tool.

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 mutation tool with no annotations, no output schema, and a non-obvious status/ipAddress dependency, the description should explain what changes, what happens to prior restrictions, and required auth. None of that is present, so an agent could call it correctly only by reading the schema closely.

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 schema already documents all five parameters including the status enum semantics and the comma-separated ipAddress format. The description adds no meaning beyond that, which is the baseline 3 case rather than a deficiency.

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?

States a specific verb and resource: 'Update IP restriction for a sub-account API key.' This clearly separates it from the read sibling BinanceSubAccountGetApiKeyIpRestriction and from BinanceSubAccountCreateApiKey/DeleteApiKey. It does not explicitly name those siblings, so it falls short of a 5.

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 use this versus the get/create/delete API-key siblings, and no stated prerequisites such as requiring a master-account API key that owns the sub-account. The agent must infer all preconditions 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.
