weather_current_conditions

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

There are no annotations, so the description carries the full burden for behavioral disclosure. It names the API provider and gives a documentation URL, but does not disclose return format, units handling, rate limits, or whether the operation is read-only. This is minimal behavioral context beyond purpose.

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 very concise and front-loaded, containing just the core purpose and a documentation link. It does not waste words, though it could be considered slightly under-specified for the tool's parameter and return complexity.

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?

With no output schema and no annotations, the description should compensate by explaining what current conditions are returned (temperature, humidity, wind, etc.) and any caveats. It does not, leaving the agent with only a vague promise of 'current conditions' and an external URL.

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 0%, and the description does not explain any parameters. 'At a location' vaguely implies latitude/longitude, but unitsSystem and languageCode are unaddressed, forcing the agent to rely only on the schema's names and enum values.

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 clearly states the tool returns 'current conditions at a location,' which is a specific resource and scope. It distinguishes from sibling forecast/history/air-quality tools by the word 'current,' though it lacks an explicit verb like 'get' or 'retrieve.'

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 use when current weather conditions are needed, and the sibling names help clarify alternatives. However, it does not explicitly state when to use this tool versus weather_forecast_days, weather_history_hours, or other weather-related tools.

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