betfair_event_timeline

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

No annotations are provided, so the description carries the transparency burden. It describes the return structure (score, timeElapsed) but does not mention side effects, authentication needs, rate limits, or error handling. The description is adequate but not comprehensive.

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, no wasted words. The first sentence states the purpose concisely; the second provides a useful structure preview. It is front-loaded and efficient.

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?

The tool has one required parameter and returns a complex object. The description gives a good return structure overview. However, it lacks explanation of optional parameters and fails to differentiate from sibling tools like 'betfair_event_timelines'. Overall, reasonably complete for a simple tool but could be better.

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?

With 0% schema description coverage, the description must explain parameters. Only 'eventId' is implicitly documented through context. Other parameters (_ak, alt, locale, regionCode, productType) have no explanation in the description or schema, leaving the agent unclear about their purpose.

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 provides a live timeline and running score/state for one in-play event. The verb 'returns' and resource specification 'live timeline + running score/state for one in-play event' distinguish it from siblings like 'betfair_event_timelines' (plural).

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 implies usage for a single in-play event but does not explicitly state when not to use or compare with alternatives like 'betfair_event_timelines' for multiple events. No exclusion criteria are provided.

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