Dependency Impact Analyzer
AI-powered dependency impact analysis for VS Code. Instantly see which files break when you change a function signature, remove a method, or modify a class — across Python, Java, JavaScript/TypeScript, Go, Rust, C#, and Ruby.
Highlights
- Live impact preview — see affected files as you type, before saving
- Transitive analysis — trace A → B → C impact chains
- AI suggestions — Claude via Amazon Bedrock explains breaks and suggests fixes
- Security audit — runs npm audit / pip-audit / cargo audit automatically
- Circular dependency detection — find import cycles
- Dead code detection — discover unused symbols
- Interactive dependency graph — force-directed visualization
- Report export — HTML, Markdown, JSON
- Git diff analysis — compare against HEAD for precision
- Impact history — track past analysis sessions
- Pre-commit hook — warn on breaking changes before committing
Quick Start
- Open a project with a supported dependency file (
package.json, requirements.txt, go.mod, etc.)
- The extension activates automatically and loads your dependencies
- Edit a function — the Impact Preview panel shows affected files in real time
- Use the Dependency Impact sidebar to browse all dependencies
