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

No annotations are provided, so the description carries the full burden. It does disclose the authentication need (GDEX_TOKEN) and the authenticated-user scope, which is valuable. However, it does not explicitly state that the operation is read-only, nor does it mention pagination, rate limits, or error behavior. The verb 'list' implies non-mutating, but an explicit statement would be stronger.

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 two concise sentences with the primary action front-loaded and no extraneous detail. Every word contributes to either the action, scope, or authentication requirement.

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?

An output schema exists, so return values are already covered. The description supplies the essential action scope and authentication requirement. Minor gaps such as pagination behavior or explicit read-only confirmation are not critical for a simple zero-parameter list tool, so it is nearly complete.

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 tool has zero parameters, and the schema is complete with 100% coverage. There are no parameters to document, so the baseline of 4 applies. No additional parameter information is needed.

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 and resource: 'List all subsetting request statuses for the authenticated user.' It clearly states the action, the object, and the scope. The word 'all' also distinguishes it from the sibling check_request_status, which likely focuses on a single status.

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 provides no guidance on when to use this tool versus alternatives like check_request_status. It only mentions the GDEX_TOKEN prerequisite, which is a requirement but not a selection criterion. There is no explicit context for choosing this tool over its siblings.

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