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

No annotations exist, so the description carries full behavioral burden. 'Query' weakly implies a read-only operation, but the description does not explicitly state that no state is changed, how the query is performed, or what happens on error. For a simple query tool this is adequate but minimal.

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?

Two lines with no filler; the action and the parameter constraint are front-loaded. Every word earns its place.

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 single-parameter query tool with an output schema, the description covers the essential semantics and valid input values. It omits explicit behavioral notes and usage conditions, but the cost is low given the tool's simplicity.

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?

With 0% schema coverage, the description's 'Device key – one of...' line adds the complete set of valid values, which the schema's bare string field does not provide. This is essential and fully disambiguates the parameter.

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 ('Query'), a concrete resource ('identification string of a device'), and the scope via allowed device keys. This clearly distinguishes it from siblings that set/get measurements, waveforms, or power-supply parameters.

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 implies the obvious use case—obtaining a device's identification string—but gives no explicit 'use when' or 'use instead' guidance. No alternatives or exclusions are mentioned, so the agent must infer when this tool is appropriate.

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