betr_statwars_events

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, but the description adds value beyond these by stating 'Auth: none needed' and explicitly listing the return structure with field names. This provides useful behavioral context about what data will be returned and confirms no authentication is required.

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 extremely concise: one line identifying the resource, one line for the return format, and one line for auth. Every sentence earns its place, with no redundancy or unnecessary elaboration.

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 no-parameter read operation with no output schema, the description provides the essential return structure and auth requirement, making it adequately complete. It does not explain the broader context of when one would need Statwars master events, but that is not critical for a simple list endpoint.

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 schema carries no parameter details. Per the baseline for 0-param tools, the description need not compensate for schema gaps. It correctly does not invent parameter-related information.

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 identifies the resource as 'Statwars master events' and adds the clarifying parenthetical 'head-to-head stats promo events', which differentiates it from generic master event tools like betr_master_event. However, it lacks an explicit action verb like 'List' or 'Get', relying on a noun phrase that implies retrieval.

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?

No guidance is provided on when to use this tool vs alternatives. It does not mention any exclusions, prerequisites, or context for selection. The only extra statement is 'Auth: none needed', which is an auth detail rather than a usage guideline.

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