Get Vehicles / 車両一覧取得

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

With no annotations provided, the description carries full burden for behavioral disclosure. It does not mention that the list is filterable by name or that limit is configurable. The description is too minimal to inform the agent about side effects, auth needs, or result structure.

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 extremely short (one sentence), which is concise, but it lacks structure and depth. It does not use the space efficiently to convey important details. It is not overly verbose, but it is under-specified.

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 the tool has two optional parameters and no output schema, the description is incomplete. It does not mention what fields are in the list, pagination, or any other behavior. Sibling tools like get_daily_reports might have similar listing functionality, but the description does not differentiate adequately.

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 parameter descriptions in the schema, so baseline is 3. The description adds no extra meaning about parameters; it does not describe them at all. Thus, it meets the baseline but adds no value beyond schema.

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 retrieves a list of all vehicles' information, which is a specific verb+resource. However, the phrase 'all vehicles' is slightly misleading as there is an optional filter parameter for partial vehicle name match. It does distinguish from sibling tools like get_drivers.

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?

No guidance is provided on when to use this tool versus alternatives like get_drivers or get_daily_reports. There is no mention of when to use it or when not to, and no exclusions.

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