+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered structurally. The description adds no behavioral context beyond a country qualifier — nothing about data source (Norwegian Met/Ozoning APIs), forecast horizon, or rate limits.
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?
It is a single fragment with zero waste and the scope is front-loaded, but at this length it is under-specified rather than concise. Brevity here costs information rather than saving it.
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?
An output schema exists so return values need not be described, but the definition omits key operational facts: the forecast time horizon, coordinate conventions for lat/lon, and the default areaclass behavior. Given three parameters and a data-fetching tool, this is too thin.
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 description coverage is only 33%; areaclass has an inline enum-style description, but lat/lon carry no explanation in schema or description (units, coordinate system). The description does nothing to compensate for the undocumented parameters.
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 resource (air-quality forecast) plus a geographic scope (Norway), which differentiates it from siblings like oceanforecast and forecast. It is clear, though it doesn't explicitly name which sibling to prefer for non-air-quality forecasts.
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?
There is no statement of when to use this tool versus forecast, nowcast, or oceanforecast, and no prerequisites or exclusions. The agent must infer routing from the phrase '(Norway)' alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
