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:

Quick Start

/plugin marketplace add dreamiurg/claude-mountaineering-skills
/plugin install mountaineering@mountaineering-marketplace

Then reload and try:

/reload-plugins
/mountaineering:research Mount Rainier

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

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.

Features

Data Sources

The skill aggregates from specialized mountaineering sites:

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

Graceful Degradation

Missing data? The skill notes what's unavailable in an "Information Gaps" section and provides manual lookup links. You always get a report, even if some sources are down.

Installation

Prerequisites: Claude Code, optionally uv for Python tools.

/plugin marketplace add dreamiurg/claude-mountaineering-skills
/plugin install mountaineering@mountaineering-marketplace
/reload-plugins

Python dependencies install automatically if uv is available. No restart needed -- /reload-plugins activates the plugin in the current session.

Usage

Commands

Natural Language

You can also just ask naturally:

"Research Mt Baker"
"Get route beta for Forbidden Peak"
"I'm planning to climb Sahale Peak, can you research it?"

Reports save to your current directory as YYYY-MM-DD-peak-name.md.

Migration from v4.x

If you previously installed the plugin as mountaineering-skills, reinstall with the new name:

/plugin uninstall mountaineering-skills
/plugin install mountaineering@mountaineering-marketplace

Dependencies

• peakbagger-cli v1.7.0 - peak data and trip reports
• Python tools - weather, avalanche, and daylight calculations

Updates

/plugin list                          # check current version
/plugin update mountaineering  # update to latest

Other Mountaineering & Outdoors Tools

I climb, scramble, and hike a lot, and I keep building tools around it. If this one's useful to you, the others might be too:

• mountaineers-mcp -- MCP server that lets AI assistants search and browse mountaineers.org. Activities, courses, trip reports, your account data. Works with Claude Desktop, Claude Code, and Codex CLI.
• mountaineers-assistant -- Chrome extension that syncs your mountaineers.org activity history and shows you stats, trends, and climbing partners you can't see on the site.
• peakbagger-cli -- Command-line access to PeakBagger.com. Search peaks, check elevation and prominence, browse ascent stats. Outputs JSON for piping into other tools.
