f1_weather

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

With no annotations, the description must convey behavioral traits. It only states 'get weather data'—no details about data format, rate limits, authentication, or error handling for invalid session_keys. The information is insufficient for safe invocation.

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, concise sentence that immediately states the tool's function. It is front-loaded with the verb, but it lacks any structure or additional details that would improve usability.

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 presence of many sibling F1 tools, the description minimally differentiates by mentioning 'weather data.' However, it does not explain the relationship to other tools (e.g., need for session_key from f1_sessions) and omits return value information since there is no output schema. The description is incomplete for effective use.

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 has one required parameter (session_key) with no description, and the tool description adds no clarification about what session_key represents or how to obtain it. Since schema description coverage is 0%, the description should compensate but fails to do so.

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 retrieves Formula 1 weather data from OpenF1, using a specific verb and resource. It distinguishes itself from sibling F1 tools like f1_drivers or f1_laps by specifying 'weather data'.

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 usage guidance is provided. The description does not specify when to use this tool versus other F1 data tools, nor does it mention prerequisites like obtaining a session_key from f1_sessions.

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