name: codebase-visualizer
description: Generate an interactive collapsible tree visualization of your codebase. Use when exploring a new repo, understanding project structure, or identifying large files.
allowed-tools: Bash(python3 *)
---

# Codebase Visualizer

Generate an interactive HTML tree view that shows your project's file structure with collapsible directories.

## Usage

Run the visualization script from your project root:

```bash
python3 ${CLAUDE_SKILL_DIR}/scripts/visualize.py .
```

This creates `codebase-map.html` in the current directory and opens it in your default browser.

## What the visualization shows

- **Collapsible directories**: Click folders to expand/collapse
- **File sizes**: Displayed next to each file
- **Colors**: Different colors for different file types
- **Directory totals**: Shows aggregate size of each folder

#!/usr/bin/env python3
"""Generate an interactive collapsible tree visualization of a codebase."""
