sportsbet_multiple_racecards

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

Beyond the readOnly and idempotent annotations, the description discloses the return structure ({racecards:[{event:{}, markets:[]}]}) and explicitly states 'Auth: none needed.' These are additional behavioral details that aid the agent in understanding what to expect, though it doesn't cover rate limits or edge cases.

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 concise, front-loaded with the primary purpose, and efficiently provides the return shape and auth requirement in two short lines. Every sentence adds value without 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?

Given the single parameter and strong annotations, the description covers the essential aspects: purpose, return format, and auth. It does not fully elaborate on the structure inside event or markets, but it's reasonably complete for a batch retrieval tool of this simplicity.

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 already provides a 100% description coverage for eventIds, including 'Comma-separated racing event ids.' The tool description adds 'batch by event ids' which reinforces the purpose but doesn't clarify the array vs comma-separated discrepancy or add additional semantics beyond the schema.

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 racecards for multiple races in a single batched call, using 'several races in one call (batch by event ids).' This distinguishes it from single-racecard tools like sportsbet_racecard by emphasizing the batching capability.

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 'in one call' implies it is used when needing racecards for multiple events, but no explicit alternatives or exclusions are stated. It doesn't directly contrast with single-racecard tools or explain when not to use it, leaving usage guidelines merely implied.

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