    Sample output

    📦 Entry Points: src/main.ts 🔄 Cycles Detected: src/auth.ts -> src/user.ts -> src/auth.ts ⚠️ Dead Code: src/utils/legacy-formatter.ts (0 inbound refs) 🚀 Core Modules: src/app.ts (Centrality: 0.82) Refactor: Split 'auth.ts' types to break the circular dependency with 'user.ts'.

    About This Skill

    What it does

    The Codebase Graph skill transforms complex, unfamiliar repositories into interactive visual maps and structured onboarding guides. It parses your project's directory structure, imports, and configuration files to build a comprehensive dependency model. Unlike manual inspection, it automatically identifies how data flows through your application, pinpointing where execution starts and where bottlenecks or technical debt reside.

    Why use this skill

    Onboarding a new developer or planning a major refactor can take days of manual code tracing. This skill automates that process by providing a high-fidelity graph that reveals hidden relationships between modules. It goes beyond simple file-tree views by detecting circular dependencies, identifying likely dead code, and ranking modules by their "centrality" to the architecture. It's an essential tool for developers who need to understand a large codebase quickly without getting lost in the weeds.

    Supported tools

    • Languages: Multi-language support including TypeScript, JavaScript, and Python.
    • Parsing: Uses AST-based analysis and framework-native metadata (like package.json) for high accuracy.
    • Visualization: Generates a standalone, interactive D3.js force-directed graph.
    • Reports: Produces detailed Markdown summaries including entry points and refactor suggestions.

    Use Cases

    • Generate an interactive D3 visualization of module dependencies
    • Identify circular dependencies and dead code candidates automatically
    • Identify entry points and core modules for rapid developer onboarding
    • Generate a markdown report with specific refactoring recommendations

    Codebase Graph needs terminal access to run language parsers (esprima for JavaScript/TypeScript, tree-sitter for Python/Go/Java/Rust). These are read-only parsers that extract structural information from source files. File read access allows the skill to scan directories and read source code to analyze imports, exports, class inheritance, and function call dependencies. Only reads files with supported extensions; ignores binary files and node_modules. File write access creates HTML visualization files and markdown summaries in a `./code-graph/` directory. All output files are safe to gitignore. The skill never modifies source code. No browser, network, or environment variable access is required. The generated HTML graph is self-contained and runs locally.

She builds for the moment when you know the process can be better, but you do not have a spare week to go spelunking through your own workflow with a headlamp and a grudge. Clear instructions. Useful defaults. Less performance. More usable machinery. Onward.
