pviz-parser

Generate LLM-optimized dependency analysis bundles from your codebase.

pviz-parser analyzes your project's dependency graph and produces a structured JSON bundle designed to fit inside an LLM context window. Instead of pasting files one by one, you give your LLM a complete picture of how your codebase is wired — nodes, edges, import relationships, cycle detection, and per-file metrics — in a single compressed artifact.

Installation

pip install pviz-parser

Quickstart

pviz . -o bundle.json --clean

That's it. Point pviz at your project root, specify an output path, and get a bundle ready to drop into Claude, ChatGPT, or any LLM that accepts file uploads or large context.

Usage

-o [options]

Arguments:<br>scan_root Root directory of the project to analyze

Options:<br>-o, --output Output path for the bundle JSON (required)<br>--clean Nuke the artifact cache before running (recommended when switching repos)<br>--store-root PATH Override the sandbox directory (default: per-user .pviz_store)<br>--mode classic|zones Build mode (default: zones)<br>--max-bytes N Per-file size limit in bytes (default: 100MB)<br>--allow-output-in-repo Allow writing the bundle inside scan_root">pviz -o [options]

Examples

# Analyze current directory<br>pviz . -o bundle.json --clean

# Analyze a specific project<br>pviz ~/projects/myapp -o ~/Desktop/myapp_bundle.json --clean

# Use a custom store root to keep artifacts organized<br>pviz . -o bundle.json --store-root /tmp/pviz --clean

What's in the bundle

The output is a structured JSON artifact with:

Nodes — one per source file, with LOC, SLOC, import/exporter counts, SCC membership, symbols, and language

Edges — directed import relationships between files

Dependency metrics — which files are most imported, which import the most, hotspots

Cycle detection — strongly connected components (SCCs) flagged at the node level

Discovery manifest — full file inventory with language breakdown

Folder index — per-file import surface and resolution data

Summary — counts, parse status, edge stats, crosstalk candidates

A compressed format is also generated alongside the standard bundle (.compressed.json), typically 55–65% smaller, optimized for tight context windows.

Rust

Kotlin, Go, and Rust analysis requires compiled binary dependencies that are part of the hosted SaaS only. Polyglot repos with multiple supported languages are handled automatically — the bundle merges all detected languages into a single artifact.

CLI vs SaaS

pviz-parser is the open source CLI. It runs locally, produces bundles you own, and supports Python, TypeScript, JavaScript, and partial resolution for Java out of the box.
