JsAnalyzer: AI-Powered JavaScript Security Analysis Tool

JsAnalyzer: AI-Powered JavaScript Security Analysis Tool

JsAnalyzer provides static analysis for JavaScript files, focusing on identifying security vulnerabilities. This AI agent skill can be triggered via various commands to perform comprehensive security scans, detecting elements such as URLs, paths, sources, sinks, postMessage handlers, and secrets.

What this skill does

• Initiates a security scan when a user requests to analyze JavaScript files or security aspects.
• Begins with parallel analyses in Phases 1 to 3, using specialized agents such as js-grep-analyzer, js-tool-runner, and js-architecture-analyzer.
• Transitions to more focused analyses in Phase 4 with agents like source-sink-tracer, postmessage-analyzer, api-investigator, and secrets-analyzer.
• Completes with a synthesis phase that compiles results into a summary report.

Who it is for

• Developers tasked with ensuring JavaScript security within their projects.
• Security teams seeking automated tools to enhance their review processes.
• AI coding agent users, specifically those using tools like Claude Code, Cursor, and Codex.

Use cases

• Performing security audits on JavaScript files found within projects to identify and rectify vulnerabilities.
• Assisting teams in developing secure applications by reducing manual code review efforts through automation.
• Enhancing existing security workflows with AI-driven analysis for complex JavaScript architectures.

Technical details

• Operates using an orchestrator pattern that delegates analysis tasks to multiple specialized agents.
• Includes agent tools like js-grep-analyzer, source-sink-tracer, and secrets-analyzer for focused analysis tasks.
• Designed for compatibility with AI coding platforms such as Claude Code, Cursor, and Codex.
