f1_mcp_server_get_session_results

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

No annotations are provided, so the description carries the full behavioral burden. "Retrieve" implies a read-only operation, but there is no disclosure of data freshness, error behavior for invalid sessions, or what "format" means, and no output schema compensates.

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?

A single front-loaded sentence with no wasted words, but it is thin to the point of under-specification for a tool with three parameters and no annotations. Brevity here reflects omission rather than disciplined editing.

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?

With no output schema and no annotations, the description should explain what "results" contain and any caveats. It instead says only that results are retrieved and formatted, leaving the agent unable to predict the return payload or failure modes.

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 description coverage is 100%, so the schema already documents year, round, and session_type with defaults and an enum. The description adds nothing beyond that, so the baseline of 3 applies.

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 a specific verb ("Retrieve and format") and resource ("results of a specific session"), which is clear on its own. However, it does not distinguish this tool from siblings like f1_mcp_server_get_event_info or f1_mcp_server_get_season_calendar, and "results" is left ambiguous (race classification? lap times? qualifying order?).

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?

There is no guidance on when to use this tool versus the many other session/event retrieval siblings, nor any mention of prerequisites such as updating data first or valid year/round combinations. The agent must infer usage entirely.

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