Mountaineering Skills for Claude Code

Automated mountain route research for North American peaks, built for Claude Code.

Quick Start • How It Works • Features • Installation • Support

Ask Claude to research any mountain. The route-researcher skill pulls from 10+ mountaineering sources and compiles a detailed Markdown report with current weather, avalanche conditions, daylight windows, trip reports, and route beta. What used to take 3-5 hours of tab-hopping now takes 3-5 minutes.

See it in action:

Peak	Elevation	What it shows
Mount Si	4,167 ft	High-traffic trail with abundant trip reports
Mount Adams	12,280 ft	Glaciated volcano with weather/avy conditions
Wolf Peak	5,813 ft	Technical scramble with sparse beta
Mount Shuksan	9,129 ft	Glacier climb requiring crevasse rescue skills
Tinkham Peak	5,398 ft	Accessible Class 2-3 scramble near Snoqualmie Pass

Quick Start

Install with npx skills:

npx skills add dreamiurg/claude-mountaineering-skills

Then just ask naturally: "Research Mount Rainier". Claude generates a route beta report in your current directory.

npx skills installs the route-researcher skill, which drives the full workflow from natural-language requests. If you also want the /mountaineering:* slash commands, install the plugin instead -- see Installation.

How It Works

The skill uses a hybrid architecture: Python scripts for deterministic API calls, LLM agents for tasks requiring judgment.

Three researcher agents gather data in parallel while a Python script fetches conditions. Dedicated agents write and review the final report. If a source fails, the skill documents the gap and continues.

Data Sources

The skill aggregates from specialized mountaineering sites:

Category	Sources
Peak info	PeakBagger
Routes	SummitPost, WTA, AllTrails, The Mountaineers
Weather	Open-Meteo, NOAA/NWS
Avalanche	NWAC, regional centers
Trip reports	PeakBagger, WTA, The Mountaineers

Coverage note: Report quality depends on how well-documented your peak is across these sources. Works best for popular North American peaks.
