get_current_weather

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

No annotations are provided, so the description must fully disclose behavior. It only states the basic function without mentioning output format, authentication requirements, rate limits, or any side effects. This minimal disclosure is insufficient for an agent to understand the tool's full impact.

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 extremely concise at five words, which is efficient. However, it lacks any structure (e.g., separate sentences for purpose, parameters, output) and could be slightly expanded for clarity without losing conciseness.

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?

Given the tool's simplicity (3 parameters, no output schema), the description covers the core purpose but omits expected return values (e.g., temperature, conditions). This gap could confuse an agent needing to interpret results. It is adequate but not fully complete.

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?

With 0% schema description coverage, the description adds little beyond parameter names. It mentions 'coordinates' but does not explain each parameter's role, format (e.g., decimal degrees), or the optional 'lang' parameter. The agent gains no extra meaning from the description.

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 'Get current weather by coordinates' specifies a clear verb ('Get'), resource ('current weather'), and method ('by coordinates'). It effectively distinguishes from sibling tools like 'get_weather_forecast' (future) and 'compare_weather' (comparison).

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?

No guidance on when to use this tool versus siblings or when not to use it. The description does not mention any prerequisites, exclusions, or alternative tools, leaving the agent to infer usage context implicitly.

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