get_current_weather

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

No annotations are provided, so the description must carry the behavioral disclosure burden. It accurately communicates a read-only, coordinate-based lookup and names the main returned data (temperature, wind, precipitation). It does not detail the response shape or any API-specific quirks, which would add clarity, but for a simple current-weather read it is adequate.

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 two compact sentences with no filler. The main operation is front-loaded, and the routing guidance is placed second where it is easy to notice.

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?

The description provides enough for an agent to decide to call this tool for current weather at coordinates and to geocode place names first. However, with no output schema and no annotations, it would benefit from a brief statement of the response format or the forecast alternative.

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 schema already describes all five parameters with 100% coverage, so the baseline is 3. The description adds only the geocoding hint, which helps clarify that latitude/longitude are required but does not enrich the optional unit or timezone parameters beyond the schema.

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 and resource: 'Get the current weather conditions' for a given latitude/longitude. The word 'current' cleanly distinguishes it from sibling get_weather_forecast, and the coordinate-based scope distinguishes it from geocode_location.

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?

It explicitly tells the agent to call geocode_location first when only a place name is available, which is clear routing guidance. It does not explicitly mention when to choose get_weather_forecast, but the term 'current' implies that boundary reasonably well.

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