get_current_weather

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

With no annotations provided, the description carries the behavioral disclosure burden. It clearly identifies the operation as 'Get' (read-only), states that results are returned as JSON, and discloses the AI summary and ambient theme components. It does not discuss data provenance, units, or failure modes, but none are critical for this simple read tool.

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 compact and front-loaded: one clear summary sentence, then concise Args and Returns sections. No filler or redundant explanation is present.

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 low complexity, the presence of an output schema, and full parameter documentation in the description, this is nearly complete. The main missing piece is explicit sibling routing guidance, but that is already accounted for in usage_guidelines.

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%, but the description fully compensates: it defines location_name as a city name with examples and lists the language options en/cs. This adds real meaning beyond the raw schema, which only provides property names and types.

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 current weather conditions with AI-powered summary.' This clearly distinguishes the tool from siblings like get_weather_forecast and get_weather_by_coordinates by emphasizing 'current' and location-name-based lookup.

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 Args section implies the intended use case: current weather for a named city/location, with an optional language for the summary. However, it does not explicitly tell the agent when to prefer get_weather_forecast or get_weather_by_coordinates instead, leaving some routing to inference.

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