nascar_races

Read-only

Get NASCAR's current-season race list feed and return its native series groups (Cup, Xfinity and Trucks) with each race's id, season, series id, race name, track identity, scheduled dates, stage lengths and source timestamps. This feed takes no selectors or parameters: it always reads the current UTC calendar year and preserves exhibition records, so historical seasons and per-race weekend data need another source. It is one public anonymous JSON feed with no upstream key, cookie or selector.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, and the description adds real context beyond that: it is anonymous, requires no upstream key/cookie/selector, always resolves to the current UTC year, and deliberately preserves exhibition records. It does not mention response size, pagination, or rate limiting for a season-long feed, which are the remaining operational unknowns.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the purpose and scope, then the parameter/auth constraints. The middle sentence is dense with a field enumeration that partly duplicates the output schema, but no sentence is filler and ordering is logical.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so the field list is bonus rather than necessity, and the description still covers the crucial constraints: no params, no auth, current-year only, no historical coverage. For a zero-argument public feed this is close to complete; only pagination and response-size behavior are unaddressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With zero parameters the baseline is high, and the description goes further by asserting the absence of selectors is a deliberate design property rather than an omission ('takes no selectors or parameters'), which prevents an agent from hunting for a season or series filter. It does not explain how to narrow to one series, implying the agent must filter client-side.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource ('Get NASCAR's current-season race list feed') and then enumerates exactly what a record carries (id, season, series id, race name, track identity, scheduled dates, stage lengths, source timestamps), plus the top-level grouping (Cup, Xfinity, Trucks). Scope is bounded to the current season, so an agent can tell this is not a live/real-time or historical feed without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear positive and negative usage conditions: use it for the current UTC calendar year, and note that 'historical seasons and per-race weekend data need another source.' That exclusion is a usable routing signal. It stops short of naming a concrete alternative (e.g., a live feed or a past-races tool), so the agent must infer which sibling fills the gap.

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