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

No annotations are present, so the description carries the burden of behavioral disclosure. It states that authentication is required and that the tool is for requesting a withdrawal (implying a request, not an immediate execution), but it does not disclose potential side effects (e.g., balance deduction timing), rate limits, or whether the withdrawal is asynchronous.

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 sentence plus a brief authentication note, which is concise and front-loaded. It contains no extraneous information, though a bit more structure (e.g., listing auth requirement separately) could improve readability.

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 the tool has 4 parameters, no output schema, and empty annotations, the description is insufficient. It does not explain what the tool returns (e.g., a request ID, success status), how to monitor the withdrawal, or whether the operation is reversible. The auth and active status hints are useful but do not provide comprehensive 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 description coverage is 100%, so the baseline is 3. The description adds no additional meaning to the parameters beyond what the schema already provides (e.g., the format of currency, minimum amount, optional note). The authentication header guidance is not parameter-specific.

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 clearly states the action ('Request a cryptocurrency withdrawal') and the resource ('from your agent wallet'). Among sibling tools, no other tool performs withdrawals, so it is well-distinguished.

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?

The description mentions authentication requirements ('Auth Required') and the method to pass the API key, but does not provide guidance on when to use this tool versus alternatives or when not to use it. The sibling list does not contain obvious substitute tools, but explicit usage context is missing.

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