get_live_weather

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

With no annotations provided, the description carries the full burden. It discloses that the tool returns live weather data (air/track temp, humidity, wind, rain) and that no auth is needed. However, it lacks behavioral details like data freshness, rate limits, or any side effects, which would be helpful for an agent.

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 a single sentence that is perfectly front-loaded with the purpose ('Live track weather') and includes the key additional info about auth. Every word earns its place, and there is no wasted text.

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 has zero parameters and an output schema exists, the description is complete enough. It tells the agent exactly what the tool does and the no-auth requirement, which suffices for invocation. No further details are needed.

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 tool has zero parameters, and the schema coverage is 100%, so baseline is 4. The description adds value by listing the specific weather metrics (air/track temp, humidity, wind, rain) that are returned, providing semantic meaning beyond the empty 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 states the tool retrieves live track weather including air/track temp, humidity, wind, and rain, with the additional clarity that no authentication is required. This clearly distinguishes it from sibling tools like 'get_weather', which likely covers historical data, and other live data tools.

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 mentions 'No auth required,' which is a usage condition, but it does not explicitly state when to use this tool over alternatives like 'get_weather' or other live data tools. The context implies it is for current weather, but no direct when-not-to-use or alternative guidance is provided.

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