Mindwalk: Open-Source Tool for 3D Replay of AI Agent Coding Sessions

What Happened

A Show HN post appeared on Hacker News for Mindwalk — an open-source tool that records AI coding agent steps and visualizes them as a 3D spatial replay. Users can 'fly through' an entire coding session, seeing where the agent hesitated, backtracked, or made a mistake.

Technical Details

• Records tool calls, file edits, and agent decisions
• 3D spatial visualization (web application)
• Open-source, integrates with popular AI coding tools

Why It Matters

Debugging AI agents is one of the biggest pain points in LLM-based development. A visual replay is a creative approach to solving this problem.
