Codebase Visualizer
Generate an interactive HTML tree visualization of the current project's file structure, with file sizes, color-coded file types, and a sidebar summary. Use when exploring a new repository, understanding project layout, identifying large files, or getting an overview of a codebase.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Generate an interactive collapsible HTML tree of the project.
Usage
Run the visualizer script from the project root:
python3 ${CLAUDE_SKILL_DIR}/scripts/visualize.py .This creates codebase-map.html in the current directory and opens it in the default browser.
What it shows
- Collapsible directory tree — click any folder to expand or collapse it
- File sizes displayed next to each file name
- Color-coded dots for file types (.js, .ts, .py, .go, .rs, and more)
- Directory size totals (sum of all files within)
- Sidebar summary: total file count, directory count, total size, number of unique file types
- Bar chart of the top 8 file types by total size
Ignored automatically: .git, node_modules, __pycache__, .venv, venv, dist, build, and any directory or file whose name starts with ..
Instructions
- Run the command above from the root of the project you want to visualize.
- Report the absolute path of the generated file.
- The script opens the file in the default browser automatically. If it does not open, tell the user to open the reported path manually.
- If Python 3 is not available, report the error from the command and stop.
