Snow Report

Get snow conditions, forecasts, and ski reports for any mountain resort worldwide. Use when asked about snow, powder, ski conditions, or mountain weather. Supports 1000+ resorts via OpenSnow. Users can set favorite mountains for quick access. Supports SnowTick 4-letter codes (JHMR, TARG, MMTH) for quick lookups.

Security Scan

This instruction-only skill is internally consistent: it fetches ski reports from OpenSnow, uses an included resort list and a local memory file for favorites, and does not request extra credentials or install software.

Purpose & Capability

Name/description (snow conditions from OpenSnow) match the instructions and reference data (resorts.md). The declared functionality (ticker lookups, favorites, comparisons) aligns with the assets in the bundle.

Instruction Scope

Runtime instructions tell the agent to open OpenSnow URLs, snapshot pages, extract forecast fields, and read/write memory/snow-preferences.md. This is expected for a web-scraping reporting skill, but it does require the agent's browser/snapshot capabilities and will create/read a local memory file for user preferences — review that file if you want to control what is stored.

Install Mechanism

No install spec or code files — instruction-only. Nothing is downloaded or written to disk beyond the stated memory file writes, so install risk is low.

Credentials

No environment variables, credentials, or config paths are requested. The skill only references OpenSnow pages and the included resorts list; requested access is proportionate to the stated purpose.

Persistence & Privilege

always is false and the skill is user-invocable. It does instruct creation/reading of a per-skill memory file (memory/snow-preferences.md) for favorites — expected behavior and limited in scope.

Assessment

This skill appears to do what it says and requires no extra credentials or installs. Before enabling it, consider: (1) it needs the agent's web/browser snapshot capability to fetch pages from opensnow.com — ensure you are comfortable with the agent opening external pages; (2) it will create/read memory/snow-preferences.md to store your default mountain and favorites — avoid putting any sensitive data in that file; (3) OpenSnow content may be partially paywalled, and the skill may visit resort sites if asked for extra details; and (4) if you plan to let agents run autonomously, remember this skill will browse external sites when invoked. If any of these are concerns, inspect references/resorts.md and the memory file template before use or disable the skill.

Commands

User Says	Action
"snowtick"	Quick ticker tape of all favorites
"snow report" / "how's the snow"	Pull default mountain from user config
"snow at Mammoth" / "Jackson snow"	Pull specific resort
"JHMR" / "what's TARG at"	Pull by SnowTick code
"compare Jackson and Targhee"	Multi-mountain comparison
"compare JHMR TARG MMTH"	Compare by tickers
"powder alert" / "where's it snowing"	Check forecasts across favorites

User Configuration

Check memory/snow-preferences.md for user settings:

First-Time Setup

If user asks for snow report with no config:

2. Create memory/snow-preferences.md with their answer
3. Ask: "Any other favorites to add for comparisons?"
4. Pull their first report

Notes

• OpenSnow is JS-rendered; browser required
• Data updates throughout day; morning reports freshest
• 11-15 day forecast may be paywalled (show what's visible)
• For resort-specific data (lifts, groomed runs), check resort's own site
