entain_event_market_rules

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

No annotations provided, and the description does not state whether the operation is read-only, idempotent, or any other behavioral traits. The minimal description leaves the agent guessing about side effects or access requirements.

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?

Extremely concise (two sentences) with no superfluous information. The structure is front-loaded with the purpose, followed by return format.

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 a described return structure, the description is complete enough to use. However, it lacks behavioral context such as whether it requires authentication or any rate limits.

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?

No parameters exist, so schema coverage is 100%. The description correctly indicates no user input is needed, meeting the baseline 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?

Description clearly states the tool returns settlement rules for every named market, indexed by rule id. The verb 'returns' and resource 'settlement rules' are specific, and the nested structure differentiates it from other market-related tools like entain_event_market_type_groups.

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 on when to use this tool versus siblings (e.g., entain_event_market_type_group_maps). Agent must infer from the name and description; lacks explicit exclusions or alternatives.

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