/mcp:setup-codemap-cli - Codebase Visualization

Set up Codemap CLI for intelligent codebase visualization and navigation, providing tree views, dependency analysis, and change tracking.

• Purpose - Enable comprehensive codebase understanding and navigation
• Output - Working Codemap installation with CLAUDE.md configuration

/mcp:setup-codemap-cli [OS type or configuration preferences]

What is Codemap?

Codemap is a CLI tool that provides intelligent codebase visualization and navigation. It generates tree views, tracks changes, analyzes dependencies, and integrates with Claude Code through hooks.

Benefits:

• Visualize project structure with smart filtering
• Track changes vs main branch at a glance
• Analyze file dependencies and import relationships
• Integrate with Claude Code through session hooks
• Generate city skyline visualizations of codebase

Arguments

Optional OS type or configuration preferences. The command auto-detects your operating system and provides appropriate installation instructions.

Examples:

• (no arguments) - Auto-detect OS and install
• macos - macOS-specific instructions
• windows - Windows-specific instructions

How It Works

1. Installation Check: Verifies if Codemap is already installed via codemap --version
2. Documentation Loading: Fetches latest Codemap documentation from GitHub
3. Installation Guidance: Provides OS-specific installation commands (Homebrew for macOS/Linux, Scoop for Windows)
4. Verification: Tests installation with basic commands
5. CLAUDE.md Update: Adds Codemap usage instructions and hook configuration
6. .gitignore Update: Adds .codemap/ directory to ignore list

Usage Examples

# Standard setup with auto-detection
> /mcp:setup-codemap-cli

# Specify your OS
> /mcp:setup-codemap-cli macos
> /mcp:setup-codemap-cli windows

After setup, your CLAUDE.md will include:

## Use Codemap CLI for Codebase Navigation

Codemap CLI is available for intelligent codebase visualization and navigation.

**Required Usage** - You MUST use `codemap --diff --ref master` to research changes different from default branch, and `git diff` + `git status` to research current working state.

### Quick Start

codemap .                    # Project tree
codemap --only md .          # Just Markdown files
codemap --diff --ref master  # What changed vs master
codemap --deps .             # Dependency flow

The command also configures Claude Code hooks in .claude/settings.json for automatic session context.

Best Practices

• Run at project start to establish codebase understanding
• Use hooks to maintain context during long coding sessions
• Combine --diff with --ref to compare against your main branch
• Use --deps to understand module relationships before refactoring
• Exclude generated files and assets with --exclude for cleaner output
