Skill Install

Automates installing Claude skills from GitHub repos while scanning them for security issues before they touch your system. It fetches the skills directory, lets you pick what to install, then runs through a security checklist looking for malicious commands, credential theft attempts, sketchy network calls, and filesystem abuse. Anything flagged as dangerous gets blocked outright, warnings let you decide, and clean skills go straight into ~/.claude/skills/. The security scanning is the real value here since you're essentially running arbitrary code from the internet. Smart middle ground between manually vetting every line and blindly trusting whatever's on GitHub.

Skill Install

Overview

Install Claude skills from GitHub repositories with built-in security scanning to protect against malicious code, backdoors, and vulnerabilities.

When to Use

Trigger this skill when the user:

  • Provides a GitHub repository URL and wants to install skills
  • Asks to "install skills from GitHub"
  • Wants to browse and select skills from a repository
  • Needs to add new skills to their Claude environment

Workflow

Step 1: Parse GitHub URL

Accept a GitHub repository URL from the user. The URL should point to a repository containing a skills/ directory.

Supported URL formats:

  • https://github.com/user/repo
  • https://github.com/user/repo/tree/main/skills
  • https://github.com/user/repo/tree/branch-name/skills

Extract:

  • Repository owner
  • Repository name
  • Branch (default to main if not specified)

Step 2: Fetch Skills List

Use the WebFetch tool to retrieve the skills directory listing from GitHub.

GitHub API endpoint pattern:

https://api.github.com/repos/{owner}/{repo}/contents/skills?ref={branch}

Parse the response to extract:

  • Skill directory names
  • Each skill should be a subdirectory containing a SKILL.md file
