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

No annotations are provided, so the description must cover behavioral traits. It only says 'check if valid' without indicating whether this is a read-only operation, what constitutes validity (e.g., signature check, format validation), or any side effects. This lack of clarity leaves the agent guessing about the tool's 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?

The description is a single short sentence, which is concise but lacks critical details. It does not waste words, but it also does not add enough value to justify its brevity. It could be expanded slightly without losing conciseness.

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 presence of an output schema and siblings like 'taxsort_request_unlock', the description is incomplete. It does not explain the output (even though output schema exists, it still helps to give context), the expected format of the 'response', or how this tool fits into a workflow. The agent would need additional 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 only 33% (only 'npub' described). The description does not add any parameter meaning beyond 'response' and 'dpop_token' are used. With three parameters and no explanation of 'response' or 'dpop_token', the tool is nearly unusable without external knowledge.

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 tool's purpose: 'Check if the unlock response is valid.' It specifies a verb ('check') and a resource ('unlock response validity'), and it implicitly distinguishes from the sibling 'taxsort_request_unlock' which would handle the request side.

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 or when not to. It does not mention that a prior call to 'taxsort_request_unlock' is needed to obtain a response, nor any prerequisites or output interpretation context. The description gives no usage context at all.

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