devicelens_prepare_identification_test

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

Annotations already indicate readOnlyHint=true, destructiveHint=false, and idempotentHint=true. The description adds that DeviceLens never disables or enables the device and that the user must perform and reverse Device Manager actions themselves, providing safety context beyond annotations.

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 concise, consisting of four sentences that front-load the purpose. No superfluous information, though it could be slightly more structured (e.g., bullet points).

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?

With annotations covering safety and idempotency, and an existing output schema (not shown), the description provides adequate behavioral context. However, it does not explain the 'identification test' itself or error conditions, which may leave minor gaps for an AI agent.

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 has 0% coverage (no parameter description). The description compensates by explaining the parameter is an interface number from devicelens_explain_device and gives an example (D03.2). This adds meaning but lacks detailed format constraints or allowed values.

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 assesses a user-operated identification test for one exact numbered interface, using a specific verb and resource. It mentions the output states whether a manual test is appropriate and why risky devices are excluded. While it doesn't explicitly differentiate from siblings, the purpose is unambiguous.

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 advises passing an interface number from devicelens_explain_device, offering a clear source. However, it does not specify when to use this tool versus alternatives (e.g., when not to use it), nor does it mention any prerequisites beyond the interface number.

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