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

No annotations are provided, so the description carries the burden. It does disclose the auth requirement and implies a read-only check, which is useful. However, it does not describe any polling behavior, error cases, side effects, or idempotency; the output schema covers return values but not behavior.

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?

Extremely lean and front-loaded: one purpose sentence plus a one-line argument definition. Every sentence earns its place with no redundancy.

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 one-parameter read-only tool with an output schema, the description is nearly sufficient. But it lacks the surrounding workflow context—such as using this after submit_subset_request or when to prefer list_request_statuses—so it is not fully 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?

Schema coverage is 0%, so the description must compensate. It provides only 'rindex: Request index/ID,' which largely restates the parameter name and gives no guidance on how to obtain the index, what format is expected, or whether it comes from a prior submit response.

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 ('Check'), a specific resource ('status of a specific subsetting request'), and the 'specific' wording distinguishes it from sibling list_request_statuses. No ambiguity about what the tool does.

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 on when to use this tool versus alternatives like list_request_statuses or submit_subset_request. The only contextual note, 'Requires GDEX_TOKEN,' is a prerequisite, not a usage condition or exclusion.

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