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 valuable context beyond annotations: the exact return structure, the semantic meaning of the id field, and the absence of authentication requirements. No contradictions found.

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-organized: a one-line definition, a return format specification, an example, and an auth note. Each section earns its place with no redundant information, and the main purpose is front-loaded.

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 that the tool has only one parameter, full schema coverage, and strong annotations, the description provides sufficient additional context: return format, field semantics, a concrete example, and auth requirements. It is complete for an agent to select and invoke the tool correctly.

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% for the single parameter eventUuid, which is described as 'Event uuid from motogp_events.' The description adds a concrete example UUID, but this does not fundamentally enhance understanding beyond what the schema already provides. Baseline 3 is appropriate.

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 defines the tool as returning the classes/categories (MotoGP, Moto2, etc.) running at a specific event. It specifies the output fields and connects to other motogp tools (sessions, standings), distinguishing it from sibling tools like motogp_events or motogp_standings.

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 states that the returned `id` is the categoryUuid needed by session and standings tools, providing clear use-case context. It also includes an example and notes that no auth is needed, but it does not explicitly mention alternatives to avoid or conditions 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.
