Resort conditions

get_resort_conditions

Read-onlyIdempotent

The latest snow report for one resort with provenance, inside the conditions contract v2 envelope: data.status is the derived operating status (OPEN, CLOSED_TODAY, PRE_SEASON, OFF_SEASON or UNKNOWN; OPEN only on a fresh operator lift feed or a resort-confirmed opening date, never by default) with reasons; every field in data (base depth measured and operator-reported, new snow 24 h / 48 h, SWE, percent of normal, lifts and runs open / total, surface, snow quality, temperature, wind, blended 48-hour forecast, season dates) is {value, source, observedAt, confidence, freshness: {tier, ageHours}}; depthDisagreement is set when the station and the operator differ by more than 30 % (quote the measured value); sentence is a dated line to quote. The classic Resort document (snow, season, cams, profile, measuredNow) rides alongside for compatibility. Use it for "is X open today" as well as "what are conditions at X". Sources: snotel = measured at a USDA NRCS SNOTEL station near the resort (station elevation, not the summit), open_meteo = weather-model estimate for resorts without a station.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`slug`	Yes	PeakCam resort slug, lowercase kebab-case, e.g. `breckenridge` or `ski-portillo`. Get it from search_resorts.

Output Schema

TableJSON Schema

Name	Required	Description
`cams`	Yes
`data`	Yes
`meta`	Yes
`name`	Yes
`slug`	Yes
`snow`	Yes	Null when the resort has never had a snow report.
`score`	No	Today's 0–100 Snow Score with components (P7). Null when the scorer has not written a row at most 3 days old; absent only when the score table is not served.
`apiUrl`	Yes
`season`	Yes
`license`	Yes	URL of the terms that govern reuse.
`profile`	Yes
`forecast`	No	Headline numbers from the blended 14-day forecast (summit point when one exists). Null when no run is current; absent on list and compare rows. The full daily blend and every model run are at `/resorts/{slug}/forecast`.
`location`	Yes
`sentence`	Yes	A dated, source-labelled status sentence that can be quoted verbatim.
`stations`	No	Observation stations serving the resort, once the station layer is live.
`schemaUrl`	Yes	The JSON Schema this document validates against.
`updatedAt`	Yes	Newest instant among the snow report and cam checks/captures.
`websiteUrl`	Yes
`attribution`	Yes
`measuredNow`	No	Latest observation per station, once the station layer is live.
`canonicalUrl`	Yes	The resort's PeakCam page. Cite this.
`schemaVersion`	Yes	Contract version; the schema file name carries the major.
`forecastScores`	No	Per-model verification at this resort over 90 days, ranked; empty until the scorer has measured days. Detail at `/resorts/{slug}/forecast-accuracy`.

A4.2/5.0

Behavior5/5

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

Annotations already establish the safe read-only profile, and the description adds substantial behavioral detail beyond them: the OPEN-only-on-fresh-feed rule, the meaning of UNKNOWN, the 30% depthDisagreement trigger, what `sentence` is for, and the distinction between snotel (measured, station elevation not summit) and open_meteo (model estimate) sources.

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

Conciseness3/5

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

The first sentence front-loads the purpose well, but the body enumerates nearly every field inside `data` and the legacy Resort document even though an output schema exists — that detail is largely duplicated in structured data. Dense parenthetical packing makes it heavier than it needs to be.

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?

For a one-parameter, read-only tool with a full output schema and covering annotations, an agent has everything needed to call it correctly, and the status/source semantics are genuinely useful. It over-delivers on return-value detail rather than leaving gaps, so completeness is high but not perfectly matched to what the schema already provides.

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 single `slug` parameter is fully documented in the schema (100% coverage) including kebab-case format and where to obtain it. The description adds no parameter-specific guidance, so it relies on the schema baseline of 3; the source-type explanation is about returned data, not the input.

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 a specific verb and resource ('latest snow report for one resort'), plus the envelope shape it returns (conditions contract v2). It is clearly distinguishable from siblings like get_resort_profile, get_snow_history, or compare_resorts because it is scoped to a single resort's current conditions.

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?

Explicitly names two triggering questions: "is X open today" and "what are conditions at X", and tells the agent where the required slug comes from (search_resorts). It does not name alternative siblings (e.g., get_forecast for future outlook, get_snow_history for past), so it stops short of a 5.

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