get_driver_details

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

There are no annotations, so the description must communicate the tool's behavior. It indicates a read operation via 'Get' and specifies what is returned, but does not disclose side effects, permissions, or output structure. Given the tool's likely read-only nature, the lack of additional behavioral notes is acceptable but not exemplary.

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 that is front-loaded with the action and object. Every word adds meaning, and there is no redundancy or filler.

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 getter with one parameter and no output schema, the description covers the main purpose and return categories. However, it lacks any mention of the input parameter or potential edge cases, though these are relatively obvious from the tool name and schema.

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 input schema exposes a single required driver_id property with no description, and the description does not mention this parameter at all. With 0% schema coverage and no parameter explanation in the description, the agent receives no guidance on how to supply the driver identifier.

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 the specific verb 'Get' with the resource 'driver details' and enumerates the data categories (profile, vehicle info, performance score), making the tool's function unambiguous. It clearly differentiates from sibling tools like update_driver_details or verify_driver by focusing on retrieval of comprehensive data.

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 when a complete driver profile is needed but provides no explicit guidance on when to choose this over alternative tools like verify_driver or get_next_driver. No when-not conditions or alternative references are given, leaving the context to be inferred.

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