get_session_details

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

With no annotations provided, the description carries full burden and does well by specifying the data scope (2018-present), what information is included (session overview, metadata, weather, fastest lap, driver classifications, analysis data), and default behaviors for optional parameters. It doesn't mention rate limits, authentication needs, or error conditions, but provides substantial 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 efficiently structured with clear sections (primary purpose, usage guidelines, parameters, returns, examples). Every sentence adds value - no redundant information. The bold formatting highlights key directives without adding unnecessary length.

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 complexity (5 parameters, comprehensive data return) and the presence of an output schema (which handles return values), the description is complete. It covers purpose, usage guidelines, parameter semantics, and behavioral context thoroughly. The examples provide concrete usage patterns that complement the parameter explanations.

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?

With 0% schema description coverage, the description compensates well by explaining all 5 parameters: year range (2018-2025), gp format (name or round number), session types with abbreviations explained, and the purpose of the two boolean flags. It provides concrete examples showing parameter usage, though it doesn't explain all possible session type values beyond the listed ones.

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 explicitly states the tool's purpose as providing 'comprehensive Formula 1 session overviews (2018-present)' and lists specific data elements included. It clearly distinguishes this from sibling tools by emphasizing it's the 'PRIMARY TOOL' for session overviews, contrasting with more specific tools like get_session_results or get_session_weather.

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 explicit guidance on when to use this tool ('ALWAYS use this tool instead of web search' for complete session information) and when not to use alternatives ('DO NOT use web search for F1 session overviews'). It also implicitly guides away from more specific sibling tools by emphasizing comprehensive coverage.

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