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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does communicate that the tool returns balance, owner, and metadata, and 'Get' implies a read-only operation. However, it does not address error behavior, address format expectations, or whether the operation is guaranteed to be side-effect free.

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, well-structured sentence with no filler. The core purpose is front-loaded ('Get account details by address') and the output fields are appended compactly.

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 one-parameter getter, the description plus input schema provides enough to select and invoke the tool. It names the main return fields, though without an output schema, an agent must infer the exact shape and units of balance, owner, and metadata.

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 already documents the single parameter 'address' as 'Account address' with 100% coverage, so the description is not required to explain its meaning. The description adds minimal extra semantic value beyond confirming the address is used to identify the account.

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 verb (Get), the resource (account details), the lookup mechanism (by address), and the key returned fields (balance, owner, metadata). This distinguishes it from the sibling tools, which target blocks, transactions, ABIs, and listings.

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 given about when to choose this tool over alternatives, nor are any exclusions or related tools mentioned. The agent must infer that get_account is appropriate whenever account details are needed.

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