Claude Code Skills Manager#

#Introduction

Claude Code Skills Manager (ccsm) is a CLI tool for discovering, installing, and managing Claude Code skills from Git-based marketplace repositories. It lets you register any public Git repository that exposes a skills.json manifest as a skill source, then search, install, update, and remove skills through a single command-line interface.

Skills are deployed directly into Claude Code's own skills directory (~/.claude/skills/), where Claude Code picks them up automatically at startup.

#Installation

git clone https://onixbyte.dev/onixbyte/claude-code-skill-manager.git
cd claude-code-skill-manager
cargo install --path .

git clone https://onixbyte.dev/onixbyte/claude-code-skill-manager.git
cd claude-code-skill-manager
cargo build --release

#Quick Start

#Registering a marketplace

A marketplace is any public Git repository with a skills.json manifest at its root. Register one with:

ccsm marketplace add https://github.com/example/skills

CCSM fetches the manifest and caches it locally. You can register as many marketplaces as you need.

#Browsing and installing skills

# Search across all registered marketplaces
ccsm search

# Search with a keyword filter
ccsm search git

# Install a skill by name
ccsm install my-awesome-skill

# If the same name exists in multiple marketplaces, disambiguate
ccsm install my-skill --marketplace my-marketplace

#Managing installed skills

# List installed skills
ccsm list

# Show details about an installed skill
ccsm info my-awesome-skill

# Update all installed skills to their latest versions
ccsm update

# Update a specific skill
ccsm update my-awesome-skill

# Remove a skill
ccsm remove my-awesome-skill

#Marketplace management

# List all registered marketplaces
ccsm marketplace list

# Refresh cached manifests (all marketplaces)
ccsm marketplace update

# Refresh a specific marketplace
ccsm marketplace update my-marketplace

# Remove a marketplace
ccsm marketplace remove my-marketplace

#Install modes

CCSM supports two deploy modes:

Set the default mode in your config, or override per install:

ccsm install my-skill --link

#Creating Your Own Skill Marketplace

A marketplace is simply a public Git repository containing a skills.json manifest. There is no server component, no authentication, and no API key — CCSM reads the manifest directly from the Git forge's raw file endpoint.

#Marketplace repository structure

your-marketplace-repo/
  skills.json        # Required: the manifest
  README.md          # Optional

#The skills.json manifest

{
  "name": "My Marketplace",
  "version": "1.0.0",
  "skills": [
    {
      "name": "my-skill",
      "description": "A short description shown in search results",
      "repository": "https://github.com/user/skill-repo",
      "branch": "main"
    },
    {
      "name": "another-skill",
      "description": "A skill that lives in a monorepo subdirectory",
      "repository": "https://github.com/user/monorepo",
      "branch": "main",
      "path": "skills/another-skill"
    }
  ]
}

#How it works

1. Manifest fetching — CCSM constructs a raw-file URL from the marketplace repository URL and fetches skills.json from either the main or master branch. This works with GitHub, Gitea, GitLab, and any Git forge that exposes raw file endpoints.

2. Skill downloading — When a user installs a skill, CCSM downloads the skill repository archive (ZIP or tar.gz) from the Git forge, extracts it, and deploys the files to ~/.claude/skills/<name>/.

3. Monorepo support — If a skill entry specifies a path, CCSM navigates into that subdirectory after extraction before deploying, so a single repository can host multiple skills.

#What goes in a skill repository

Each skill repository is a standard Claude Code skill directory. At minimum it should contain a SKILL.md manifest file:

my-skill-repo/
  SKILL.md           # Claude Code skill manifest
  script.py          # Supporting files
  templates/
    template.txt

#Publishing steps

1. Create a public Git repository with a skills.json at the root, following the format above.
2. Push it.
3. Anyone can register it with ccsm marketplace add <url>.

#How CCSM Stores Data

On Windows, ~/.config/ resolves to C:\Users\<user>\AppData\Roaming\.
