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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, covering the safety profile. The description adds meaningful context beyond annotations: the exact return shape, status enum values, the 'lastFinishedRound' field, the nested series object, and an explicit auth requirement. This enriches what the agent can expect.

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 compact and well-structured: first the core purpose and sequencing, then the return format, a brief example, and auth status. Every sentence serves a purpose with no filler.

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 zero-parameter, read-only listing endpoint with rich annotations, the description is complete. It includes the return structure, status enum, example, auth note, and the crucial 'call this first' guidance. No output schema exists, so the description appropriately carries the return-format responsibility.

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 tool has zero parameters, so the baseline of 4 applies. The description does not need to add parameter details, and it does not introduce any confusion about inputs.

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 returns every Formula E season with its UUID, establishing a specific purpose and resource. The phrase 'call this first, everything else needs the id' distinguishes it from sibling Formula E tools like formulae_races and formulae_race.

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 gives explicit sequencing guidance: 'call this first, everything else needs the id.' It also confirms no auth is needed, which helps the agent decide when to call it. It does not name specific alternative tools or exclusions, but for a zero-parameter root endpoint this is clear enough.

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