Get Vehicle Safety Information

get_vehicle_safety

Read-only

Use this for available NHTSA-backed recalls, complaints, investigations, manufacturer communications, and safety ratings. Safety facts remain explicitly YMM-scoped and never establish configuration identity.

Input Schema

TableJSON Schema

Name	Required	Description
`vin`	No	Full 17-character VIN. Use VIN by itself as the identity path, or omit it and provide year, make, and model.
`make`	No	Vehicle make. Required with year and model when VIN is not provided.
`trim`	No	Optional identity refinement. Use only an explicitly known trim.
`year`	No	Model year. Required with make and model when VIN is not provided.
`limit`	No	Maximum records per safety category
`model`	No	Customer-facing model family. Required with year and make when VIN is not provided.
`engine`	No	Optional identity refinement. Use only an explicitly known engine.
`drivetrain`	No	Optional identity refinement. Use only an explicitly known drivetrain.
`configuration_id`	No	AUTO411 configuration identifier returned by a prior NEEDS_IDENTITY response.

A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, covering the safety profile. The description adds a genuine behavioral caveat — that safety facts are YMM-scoped and 'never establish configuration identity' — which usefully tells the agent not to treat results as identity resolution. It does not, however, cover return granularity or the external-source semantics implied by 'NHTSA-backed'.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero filler, with the capability list front-loaded ahead of the scoping caveat. The second sentence is dense but carries distinct meaning, so little is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With a full output schema, 100% parameter coverage, and read-only annotations, the description only needs to frame the data family and the YMM-scoping constraint — which it does. The one gap is a lack of explicit routing versus sibling tools such as resolve_vehicle, but the core call context is complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema fully documents the VIN-vs-YMM identity paths, optional refinements (trim, engine, drivetrain), configuration_id, and limit. The description adds no parameter-level syntax or defaults, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource set (NHTSA recalls, complaints, investigations, manufacturer communications, safety ratings), which clearly distinguishes it topically from siblings like get_vehicle_efficiency, get_vehicle_fitment, and get_vehicle_specs. The verb 'Use this for' is a usage cue rather than a crisp action verb, but the data categories are concrete enough that an agent knows what it retrieves.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The opening 'Use this for available NHTSA-backed...' signals when to select the tool, and its topic contrast against the other get_vehicle_* siblings is implied. However, it never names an alternative explicitly, gives no precedence rule against resolve_vehicle, and states no exclusions, so guidance is only implied.

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