Cccsc

Claude Code custom slash commands package manager for easy sharing and management of commands

Usage

No installation required! Use npx to run cccsc commands directly:

Add a command from GitHub repository

# Add specific command (defaults to local)
npx cccsc add user/repo/commandName

# Add all commands from repository
npx cccsc add user/repo

# Add with alias
npx cccsc add user/repo/commandName --alias my-command

# Add to global commands
npx cccsc add user/repo/commandName --global

# Add from specific branch
npx cccsc add user/repo/commandName --branch develop

Note: Commands are installed locally by default. The .claude directory must exist in the target location.

Install commands from cccsc-lock.json

npx cccsc install

List installed commands

# List all commands
npx cccsc list

# List local commands only
npx cccsc list --local

# List global commands only
npx cccsc list --global

Remove a command

npx cccsc remove commandName

Update commands

# Update all commands based on cccsc.json constraints
# Shows diff preview and asks for confirmation
npx cccsc update

# Update global commands only
npx cccsc update --global

The update command will:

1. Check each repository for new commits based on branch constraints
2. Show a detailed diff of changes
3. Ask for confirmation before applying changes
4. Update the lock file with new revisions

Files

Local files (project-specific)

• cccsc.json - Configuration file listing desired repositories and commands
• cccsc-lock.json - Lock file with exact repository revisions

Global files

• ~/.cccsc/cccsc.json - Global configuration file
• ~/.cccsc/cccsc-lock.json - Global lock file

Configuration file structure (cccsc.json)

{
  "repositories": {
    "user/repo": {
      "only": [
        {
          "name": "optimize",
          "path": "optimize.md",
          "alias": null
        },
        {
          "name": "my-component",
          "path": "frontend/component.md", 
          "alias": "my-component"
        }
      ]
    },
    "user/another-repo": {
      "branch": "develop",
      "only": []
    }
  }
}

• only: Array of specific commands. Empty array means install all commands from repository.
• branch: Specific branch to use (defaults to "main" if not specified)

Lock file structure (cccsc-lock.json)

{
  "lockfileVersion": 2,
  "repositories": {
    "user/repo": {
      "revision": "abc1234567890abcdef1234567890abcdef123456",
      "only": [
        {
          "name": "optimize",
          "path": "optimize.md",
          "alias": null
        },
        {
          "name": "my-component",
          "path": "frontend/component.md", 
          "alias": "my-component"
        }
      ]
    },
    "user/another-repo": {
      "revision": "def7890abcdef1234567890abcdef123456789abc",
      "only": []
    }
  }
}

• revision: Git commit hash for the repository
• only: Array of specific commands to install. Empty array means install all commands.

Command Installation Paths

• Local (default): .claude/commands/cccsc/user/repo/ - accessible as /project:commandName
• Global: ~/.claude/commands/cccsc/user/repo/ - accessible as /user:commandName

Requirements: The .claude directory must exist in the target location before installing commands.
