Building Self-Healing Test Loops for Python Code Edits in LuxurAI Coder

What We Built Today

Today, I improved LuxurAI Coder’s self-healing test loops for Python code edits. This feature ensures that when the AI makes changes across multiple files, it can autonomously detect and fix test failures without manual intervention.

The Problem We Solved

Autonomous code editing is powerful, but it’s useless if it breaks existing functionality. The self-healing loop catches test failures in an isolated sandbox and feeds runtime stderr back into the agent for automatic repair.

How The Architecture Works

1. SelfHealingValidator Layer: Runs tests in an isolated sandbox worker.
2. Stderr Feedback Loop: Captures runtime errors and feeds them back into the repair pipeline.
3. Fail-Closed Safety Gate: Prevents infinite repair loops on unrecoverable errors.

Transparent Economics

LuxurAI operates on a transparent ₹0.25/credit pay-as-you-go model, making it accessible for developers worldwide.

How We Can Make This Better

This is still experimental, and I’m actively working to improve sandbox reliability. If you’re a Python developer, I’d love your feedback on how to make this more robust!
