vehicle.decode-wmi

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

No annotations provided, so description must disclose behavioral traits. It only states the action and result, with no mention of error handling, authentication, rate limits, or side effects. For a simple decode, moderately acceptable 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?

Single, concise sentence that efficiently conveys the tool's purpose without wasted words. Front-loaded with key information.

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 simple 1-parameter decode tool with no output schema, the description is adequate. However, it could mention potential response format or an example to improve completeness.

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 coverage is 100% with description '3-character WMI code.' The tool description adds 'first 3 chars of a VIN' which provides context but does not add significant meaning beyond the schema. Baseline 3.

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?

Description clearly states verb 'Decode' and resource 'WMI' with specific meaning (first 3 chars of VIN) and outcome (to manufacturer). It distinguishes from siblings like vehicle.vin-decode (full VIN) and vehicle.manufacturers.

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?

Implies use when you have a 3-character WMI code and want manufacturer, but does not explicitly state when to use this vs. alternatives like vehicle.vin-decode or vehicle.manufacturers. No when-not or exclusion criteria provided.

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