Championship Standings (1950+)

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds the 1950+ coverage window and the year=0 sentinel, which is useful, but says nothing about pagination, rate limits, or data-source caveats beyond that.

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?

Front-loaded purpose followed by a compact args block; every line earns its place for a two-parameter tool. The arg list is terse but not padded.

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?

Both parameters are documented and an output schema exists, so return values need not be explained. For a simple two-parameter read tool this is nearly sufficient; the only missing piece is sibling disambiguation against the other standings 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?

With schema coverage at 0%, the description carries the parameter burden, and it does so well: it clarifies that year=0 means the current season (a non-obvious sentinel the schema only shows as a default) and that standings_type accepts 'driver' or 'constructor' (no enum exists in the schema). It stops short of detailing accepted year ranges or invalid values.

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?

States a specific verb+resource ('Get championship standings') with a temporal scope ('1950 to present'), which is more precise than the bare name suggests. It does not, however, distinguish itself from the overlapping siblings get_standings, get_driver_standings, and get_constructor_standings, which an agent must disambiguate among.

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?

Usage is only implied through the two arguments (year, standings_type='driver'|'constructor'), which gesture at when each mode applies. There is no explicit when-to-use guidance, no exclusions, and no mention of the near-duplicate sibling standings tools it must be chosen over.

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