Code Visualizer

Generates mermaid flow diagrams from your codebase across Python, TypeScript, JavaScript, Rust, and Go. Point it at a directory and it spits out one diagram per language showing imports and dependencies, plus an optional combined view with subgraphs. The staleness detection is genuinely useful: it compares file mtimes against your committed diagrams and tells you when they're out of sync. Built with a clean brick architecture where each language analyzer is self-contained and outputs to a normalized graph format. Reaches for regex parsers instead of full ASTs for most languages, which keeps it fast but means it might miss exotic syntax. Best for onboarding docs, PR reviews, and catching when your architecture diagrams have drifted from reality.

Code Visualizer Skill

Purpose

Automatically generate and maintain visual code flow diagrams across multiple programming languages. The skill auto-detects which languages are present in a target path, analyzes each one with a dedicated analyzer, and emits one mermaid diagram per language plus an optional combined high-level view. It also detects when committed diagrams are stale relative to the source they describe.

What's New in 2.0.0

Multi-language support: Python, TypeScript/JavaScript, Rust, and Go.
Language dispatcher: Detects languages by file extension and routes to per-language analyzers.
Language-blind renderer: A single mermaid renderer consumes a normalized graph; the renderer never inspects language semantics.
One diagram per language plus an optional --combined view that places each language in its own mermaid subgraph.
Generalized staleness: Walks all source files matching detected languages' extensions and compares max-mtime against the diagram mtime.
Brick-style architecture: Each language analyzer is a self-contained module that exposes a single normalize() function. No shared inheritance.
