openf1_sessions

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

No annotations provided. The description indicates it returns a list of session objects with fields, implying a read operation. However, it lacks details on pagination, error handling, or any constraints beyond filtering.

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?

Two sentences: first clearly states purpose, second explains usage and return format. Concise and front-loaded with key information.

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 7 optional parameters, no output schema, and no annotations, the description provides a clear response structure and mentions filtering. It could be improved by explaining all parameters, but it's largely complete for a list retrieval tool.

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 has 7 parameters with 0% coverage. The description mentions only three filters (year, country, session_name) explicitly, leaving others like meeting_key, session_type, circuit_short_name unexplained. It does not compensate for the lack of schema descriptions.

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 F1 sessions (Practice, Qualifying, Sprint, Race) using specific filters. It distinguishes itself among sibling openf1_* tools by specifying the data type and filtering options.

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 says 'filter by year, country or session_name to find a session_key' which implies typical use cases, but it does not explicitly state when not to use this tool or compare it to alternatives like openf1_meetings or openf1_laps.

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