entain_featured_slider

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

The description adds 'Auth: none needed' and a detailed return structure, which go beyond the annotations that only mark it read-only, idempotent, and open-world. This gives the agent practical information about invocation and response. No contradictions with annotations.

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 two lines: first line gives the purpose, second line details return and auth. It is front-loaded and every sentence adds value.

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 simple read-only tool with no parameters and no output schema, the description provides the complete return structure and auth requirement. It is sufficiently detailed for an agent to invoke and interpret the result.

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 provides no parameter meaning. The description appropriately omits parameter details and instead focuses on return structure. Baseline 4 for zero-parameter tools.

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 ('featured slider events') and specifies it's the 'homepage hero carousel', which differentiates it from other entain tools. It lacks an explicit verb like 'list' or 'get', but the return structure implies retrieval. Among dozens of siblings, this is uniquely about the featured slider.

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 does not explicitly state when to use this tool versus alternatives, nor does it offer exclusions. However, the clear context ('homepage hero carousel') implies use for fetching the hero carousel events. There is no mention of alternative tools for this specific data.

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