Show HN: Mindwalk – Replay coding-agent sessions on a 3D map of your codebase
Mindwalk is a new visualization tool that allows developers to replay coding-agent sessions by mapping them onto a 3D representation of their codebase. The tool helps users understand how AI agents navigate and modify files by visualizing their activity as light moving across a repository map.
Why it matters
As AI coding agents become more prevalent, tools that provide transparency into their decision-making processes are essential for debugging and trust.
A visualization tool that replays coding-agent sessions on a 3D map of your codebase.
A session log records what an agent did, but not how it understood the task: which parts of the repo it treated as relevant, where it explored before it acted, whether its footprint matched the scope you had in mind. Reading the raw JSONL line by line doesn't answer any of that.
Draw the repository as a night map, and play the session back as light moving through it: where the agent searched, read, and edited, the map glows — everything else stays dark. The agent's understanding of the task becomes a shape you can see at a glance. One Go binary reads Claude Code and Codex session logs, fully local; no session data leaves your machine.
