entain_featured_slider

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

Annotations already declare the tool read-only, open-world, and idempotent, so the description adds useful auth context: it works without a key but ENTAIN_REFRESH_TOKEN unlocks more data. It also discloses the exact response contract, which is valuable because there is no output schema. No contradiction 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 compact and front-loaded: a one-line purpose, a precise return shape, and a one-line auth note. Every sentence earns its place, and no fluff or redundant explanation is present.

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 fetch tool, the description gives everything needed to call it and interpret results: the source, the exact item fields, nested event details, and auth behavior. The annotations cover safety and idempotency, so no critical guidance is missing.

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?

There are zero parameters, so there is no parameter semantics burden on the description. The empty schema with 100% coverage means nothing is undocumented; the description appropriately focuses on the return shape and auth behavior instead.

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 identifies a specific resource: featured slider events from the homepage hero carousel. It clearly distinguishes this from the many other Entain content tools by naming the exact source, though it lacks an explicit verb like 'list' or 'get'.

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 phrase 'homepage hero carousel' implies this tool should be used when an agent needs featured homepage slider content, and the provided return shape confirms its purpose. However, it does not explicitly state when to use it over alternatives or mention any exclusion criteria.

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