A CLI tool that copies a single Agent Skill file from a public GitHub repository into a local agent's skills directory.

Makes it easy to initialize a project with the skills you need.

skill-copy <github-tree-url> <destination>

The tool:

1. Validates the folder is a skill (must contain SKILL.md)
2. Creates <destination>/<skill-name>/
3. Copies all files and subdirectories into it

Option 1: Download a pre-built binary (no Go required)

Download the latest release for your platform from the GitHub Releases page, extract the archive, and move the skill-copy binary to a directory on your PATH.

Option 2: Install with Go

# first make sure your GOPATH is set
go install github.com/briangershon/skill-copy@latest

Option 3: Installation into a Dockerfile

For an example of skill-copy being installed and used in a Dockerfile, see Agent Workspace.

Each agent has a different skills directory. For example, Claude's skills directory is ~/.claude/skills for the current user.

So if you want to install skill-creator Skill for Claude, you would run:

skill-copy https://github.com/anthropics/skills/tree/main/skills/skill-creator ~/.claude/skills

This will copy it into ~/.claude/skills.

go build -o skill-copy .

Merge changes to main, then tag and push:

make tag TAG=v1.2.3

This creates the git tag and pushes it to origin. Once pushed, go install github.com/briangershon/skill-copy@latest will resolve to the new tag, or visit Releases on GitHub to download the pre-built binaries.
