sportsbet_racing_best_bets_with_events

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

Annotations already cover the read-only, idempotent, and open-world nature, so the description adds value by specifying the exact return structure ({bestBets:[{event:{eventId, raceNumber}, selectionName, price:{winPrice}}]}) and stating 'Auth: none needed.' This goes beyond annotations without contradicting them.

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: two short sentences plus a return format block. The first sentence front-loads the core purpose, and every element provides useful information with no redundancy.

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 parameterless tool with no output schema, the description gives a concrete return shape and auth note, covering the essential information an agent needs. It doesn't clarify what constitutes a 'best bet' or any implicit scope, but given the low complexity, this is largely sufficient.

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 input schema carries no semantic weight. The description appropriately provides the return shape, which is sufficient given the lack of parameters, and the schema coverage is trivially 100%.

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 states it returns 'Best bets with their full parent event objects inlined', clearly specifying the resource (best bets) and the distinguishing feature (event objects inlined) relative to siblings like sportsbet_racing_best_bets. The action is implied by 'Returns', making the purpose unambiguous.

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 gives no explicit guidance on when to use this tool versus alternatives, nor does it mention any exclusions or prerequisites. It doesn't name alternatives or suggest a context like 'use this when you need event object details', though the title and first line hint at this.

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