Get Road Conditions

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

With no annotations, the description must carry behavioral disclosure, and it does describe the returned content (surface conditions and temperatures) plus a filtering capability. However, it omits data freshness, update cadence, pagination behavior, and any auth requirements for what is implicitly a read-only data feed.

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?

Three short sentences with the core purpose and returned data front-loaded; no filler. It could be slightly tighter but every sentence contributes 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?

No output schema exists, so the brief summary of returned fields is welcome but thin, and no pagination or freshness detail is given. Since all parameters are fully described in the schema, the main remaining gap is behavioral context rather than call correctness.

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%, so both parameters (limit, roadNumber) are already fully documented in the schema. The description only echoes road-number filtering and adds no syntax or format detail beyond examples already present, so the baseline 3 applies.

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?

States a specific verb (Get) and resource (road conditions) and enumerates the concrete data returned (ice, snow, water, temperatures). The resource is clearly distinct from siblings like get_weather_station, get_cameras, and get_traffic_flow, though it never explicitly names them.

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?

Provides no when-to-use guidance, no conditions selecting it over siblings such as get_traffic_situations or get_weather_observations, and no prerequisites. 'Can be filtered by road number' is parameter information rather than usage context.

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