tab_racing_jackpots

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

Annotations already declare read-only, idempotent, and open-world behavior; the description adds useful context by stating that the tool works without an API key and that setting TAB_CLIENT_ID or TAB_CLIENT_SECRET unlocks more access. No contradiction exists, though it stops short of describing pagination or data freshness constraints.

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: one for purpose and one combining return shape with auth info. It is front-loaded, compact, and every phrase adds value.

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 one-optional-parameter read-only tool, the description covers purpose, return structure, and auth requirements in a compact way. It is slightly incomplete because it doesn't clarify how the optional jurisdiction parameter filter interacts with the 'across meetings' scope, nor does it differentiate among the many sibling racing tools.

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?

There is only one optional parameter and its schema description already covers the meaning ('State jurisdiction'). The description adds no further meaning about allowed values, how the jurisdiction affects results, or the interplay between jurisdiction and 'across meetings', so it remains at the baseline for high schema coverage.

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 identifies the resource: current racing jackpot/carryover pools across meetings, and includes a return-shape hint. It does not use an explicit verb like 'get' or 'list' and offers no direct comparison to sibling TAB tools, so it is clear but not fully differentiated within the family.

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 makes it obvious when to use the tool: whenever current jackpot/carryover pool information is needed. However, it provides no explicit when-not-to-use guidance or mentions alternatives, leaving the agent to infer how this differs from the many other TAB racing tools.

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