Install GitHub Plugin

Overview

claude plugin install clones repos via SSH. If SSH auth isn't configured, or if the repo has no .claude-plugin/marketplace.json manifest, the install fails. This skill works around both problems.

Workflow

1. Clone the repo via gh CLI (bypasses SSH)

gh repo clone <owner>/<repo> "~/.claude/plugins/marketplaces/<marketplace-name>"

Use the same directory the marketplace manager would have used (check known_marketplaces.json if the marketplace was already added).

2. Check for an existing manifest
