entain_racing_next_races

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

With no annotations provided, the description must disclose behavioral traits such as read-only nature, authentication requirements, or rate limits. The description only states the purpose and return structure, omitting any behavioral context. The return format is noted but does not substitute for behavioral transparency.

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 sentences plus a return structure, which is reasonably concise. However, it includes the return structure inline, which could be considered unnecessary without an output schema. It is front-loaded with the purpose but could be more efficient by removing the return details.

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 no annotations, no output schema, and only two parameters, the description is incomplete. It fails to explain parameter semantics, behavioral impact, or usage context. For a minimal tool, more detail on parameters and expected behavior is needed to be fully helpful.

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 input schema has two parameters (count, categories) with 0% schema description coverage. The description mentions grouping by racing category, hinting at the categories parameter, but does not explain valid values or the meaning of 'count'. This adds minimal value beyond the schema itself, which is empty for categories.

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 'next races about to jump, grouped per racing category', which is a specific verb+resource combination. While it doesn't explicitly differentiate from sibling racing tools, the phrase 'about to jump' implies imminence, distinguishing it from other entain racing tools like future markets or meeting details.

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 versus alternatives such as entain_racing_future_markets or entain_racing_meeting. There are no usage constraints, prerequisites, or exclusions mentioned, leaving the agent without context for appropriate invocation.

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