GitHub Repo Installation Skill

When a GitHub URL is pasted, follow this process. Do NOT install before classifying.

Step 1 — Clone and classify

Clone the repo to /tmp/ (or $env:TEMP on Windows) and inspect the structure:

• `SKILL.md` at the root → it's a skill
• `.claude-plugin/plugin.json` → it's a plugin
• `package.json` with an MCP server entry point (look for mcp, bin, or server config) → it's an MCP server
• None of the above → standalone tool, framework, or app

Step 2 — Handle by type

Skill

Copy the entire skill directory to .claude/skills/[skill-name]/. The directory name should match the name field in the skill's frontmatter.

Plugin

Use the plugin marketplace if it's listed:

/plugin install [name]@[marketplace]
/reload-plugins

If not on a marketplace, the user must add it as a custom plugin source.

MCP Server

Add the server to .claude/settings.json under a mcpServers key. Format depends on the server — read its README.

Standalone Tool

Don't install into .claude/. Clone it to the project root or a sibling directory, depending on what makes sense.

Rules

• NEVER install before classifying
• NEVER dump an entire repo into .claude/skills/
• Verify the install worked by checking for the expected files
• If anything is ambiguous, ask the user before proceeding
