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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description's 'Check' is consistent with a safe, non-mutating operation. The description adds context about what is checked (USB enumeration, VISA runtime, PyVISA readiness), extending beyond annotations. However, it does not disclose whether the tool requires an active instrument connection, the format of results, or potential side effects like system-level queries, which would be helpful.

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, concise sentence: 'Check Windows USB enumeration, VISA runtime, and PyVISA readiness.' It is front-loaded with the verb and immediately lists the specific items checked. No unnecessary words or repetition.

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 zero-parameter diagnostic tool with an output schema, the description is nearly complete. It specifies the exact areas checked. Minor gaps: it does not explicitly tie the diagnostic to the DPO2012B instrument (relies on the tool name), and it does not indicate whether this is a host-side check or requires the instrument to be connected, which would be useful context for a user.

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 the schema description coverage is 100% (empty object). Per rubric baseline, 0 params earns a 4. The description adds nothing about parameters because none exist, and none are needed. It does not need to compensate for schema gaps.

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 uses a specific verb 'Check' and clearly identifies the resources: 'Windows USB enumeration, VISA runtime, and PyVISA readiness.' It distinguishes this tool from siblings like dpo2012b_connect or dpo2012b_identify by focusing on environment/dependency validation rather than device interaction. The tool name also scopes it to the DPO2012B oscilloscope, making the purpose 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 implies usage for diagnosing setup issues, but it does not explicitly state when to use this tool versus alternatives. It does not mention exclusions or alternatives such as 'use this before connecting' or 'use dpo2012b_connect after this passes.' No when/when-not guidance is provided beyond the general diagnostic intent.

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