Get Switch 2 Device Info

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

The description reveals that the data is 'cached', indicating it may not be real-time, which is an important behavioral trait. With no annotations provided, the description carries the full burden, and it adequately discloses the read-only nature without side effects.

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, front-loaded sentence that conveys all necessary information without redundancy. 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?

Given that there are no parameters, output schema, or annotations, the description is minimally sufficient. However, it lacks context about prerequisites (e.g., device must be connected) and does not detail the output format or potential error conditions, leaving some gaps for a complete understanding.

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 schema coverage is 100%, so the baseline is 4. The description adds meaning by listing the returned fields, though this pertains to output rather than parameter semantics. 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 clearly states the verb 'Return' and the specific resource 'cached model, serial, firmware, and manufacturer information', making the tool's purpose unambiguous. It also distinguishes itself from sibling tools, none of which retrieve device info.

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?

While the description does not explicitly state when to use or not use this tool, the purpose is straightforward and no sibling tools provide the same functionality, so usage context is clear. However, explicit guidance on prerequisites (e.g., device connection) would improve score.

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