get_session_info

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

With no annotations provided, the description carries the burden of behavioral disclosure. It explains the operation (loads), the output (metadata and driver list), and a key data constraint (FastF1 coverage starts in 2018). It does not detail failure modes or exact metadata fields, but it is not misleading and provides useful behavioral context.

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 appropriately concise: a single purpose sentence followed by a compact bulleted list of parameter definitions. It is front-loaded with the main function and contains no redundant 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?

For a simple session-information loader, the description covers purpose, all parameters, and output at a high level. Without an output schema, saying 'metadata and driver list' is slightly vague, but it is likely enough for an agent to select and invoke the tool successfully.

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 provides only parameter names, types, and defaults with 0% description coverage. The description compensates fully by explaining each parameter: year with a minimum value, circuit with examples, and session_type with a list of valid values. This gives the agent everything needed to construct valid arguments.

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's function: 'Load an F1 session and return its metadata and driver list.' This uses a specific verb and resource, and it distinguishes itself from sibling tools like get_driver_stints and get_degradation, which focus on other aspects.

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 provides clear context for when to use the tool by explaining it loads session metadata/driver list and supplying parameter constraints (e.g., 2018 or later, valid session types). However, it does not explicitly mention alternative tools or when not to use this tool.

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