Deterministic AST Static Resource Lifetime Analyzer & CodeRabbit-Style AI Code Security Engine for Python
📌 Overview
LeakGuard VS Code Extension brings enterprise-grade, offline static resource leak detection directly into your editor as you type.
Never leave unclosed database connections, sockets, files, subprocesses, thread locks, or HTTP sessions. LeakGuard statically parses your Python code using Abstract Syntax Trees (AST) without ever executing customer source files, ensuring 0% false-positive AI hallucinations on leak detection!
🌟 Key Features
🔴 Live Error Underlines: Red squiggly error underlines appear instantly on unclosed resource handles upon saving your .py file.
💡 1-Click Lightbulb Quick Fixes: Click the VS Code lightbulb (Ctrl+.) on any leak diagnostic to generate an AI patch verified inside an isolated AST sandbox.
🎙️ Voice Audio Alerts: System Voice Audio announcements alert you instantly if a leak is introduced (Ctrl+Alt+L).
⚡ What-If Exception Simulator: Simulate stack unwinding and exception paths (leakguard.whatIf) to verify cleanup safety.
📊 Commercial Web Dashboard Link: 1-Click launcher to open your LeakGuard PR Security Portal (http://localhost:3000).
