Resort snow history

get_snow_history

Read-onlyIdempotent

One resort's own snowfall history: season totals, comparison to its 5-year and 30-year averages, and best months to visit. Scoped to a SINGLE resort — for "which resort in <state/country/region> led last season", use get_season_leaderboard instead.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`slug`	No	Resort slug or name, e.g. "portillo" or "Portillo". Required unless `resort` is given.
`resort`	No	Same as `slug`: the resort slug or name. Pass either one.

Output Schema

TableJSON Schema

Name	Required	Description	Default
`markdown`	No	Human-readable markdown summary of the tool result (may be omitted when structuredContent carries a typed payload; content[0].text always has the prose).

A4.5/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds useful behavioral context about the historical, aggregate nature of the data and what comparisons are included.

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

Conciseness5/5

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

Two compact sentences with no filler. The core output is front-loaded and the scoping caveat is stated efficiently.

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

Completeness5/5

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

The description, annotations, and output schema together give enough information for an agent to invoke this correctly. The single-resort constraint, alternative tool, and expected content are all covered.

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

Parameters3/5

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

The input schema documents both slug and resort parameters with 100% coverage, including examples and the note to pass either one. The description adds no additional parameter-level meaning beyond reinforcing single-resort scope.

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?

States the tool returns one resort's snowfall history, including season totals, comparisons to 5- and 30-year averages, and best months to visit. The single-resort scope and explicit contrast with get_season_leaderboard make its purpose clear.

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

Usage Guidelines5/5

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

Explicitly says it is scoped to a single resort and tells the agent to use get_season_leaderboard instead for region-level 'which resort led <metric>' questions. This provides clear when-to-use and when-not-to-use guidance.

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