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

With no annotations, the description carries full behavioral disclosure burden. 'List' signals a read-only query and 'current Lodestar Stamp draft' scopes the data, but the description does not say what the returned domains look like, what happens if no draft exists, or whether any other side effects occur.

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 with no filler, front-loading the action and object. Every word adds meaning, and nothing repeats annotations or schema information.

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 zero-parameter, low-complexity tool, the description gives enough to understand the essential purpose and scope. There is no output schema, so the exact return shape is inferred rather than documented, but the gap is minor for a simple list operation.

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 input schema is empty and there are zero parameters, so the baseline is 4. The description does not need to add parameter-level meaning because no parameters exist.

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 uses a specific verb ('List') and a precise resource ('domains covered by the current Lodestar Stamp draft'), making the tool's purpose immediately clear. It is distinct from siblings like find_business, get_receipt, and list_markets even without naming them.

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 phrase 'covered by the current Lodestar Stamp draft' implies when this tool is relevant, but there is no explicit guidance about when to use it versus a sibling alternative. No exclusions or routing hints are provided, so usage is only implied rather than stated.

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