update_driver_location

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not state side effects, validation behavior, error handling, or whether it overwrites the existing location. The phrase 'current real-time location' hints at a live update but lacks depth.

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?

A single, front-loaded sentence with no filler or redundant phrasing. It efficiently conveys the core action, making it easy to parse. The brevity is appropriate for the tool's simplicity.

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 lack of annotations, no output schema, and a terse description, the tool's complete behavior is not sufficiently explained. It does not mention return values, prerequisites, side effects, or edge cases. Though the tool is simple, the description leaves significant gaps for a mutation operation.

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 has 100% coverage, describing both driver_id and location_id adequately ('Driver ID', 'New location ID from Locations table'). The description adds no additional parameter semantics beyond what the schema already provides, so it meets the baseline for high schema coverage.

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 ('Update') and resource ('driver's current real-time location'), clearly distinguishing it from sibling tools like update_driver_availability and update_driver_details. It precisely identifies the action and the object.

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 provides no guidance on when to use this tool versus alternatives, lacks prerequisites (e.g., driver must exist, driver must be active), and does not mention any exclusions or alternative tools. It simply states the action without any context.

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