Mindwalk: Replay AI coding-agent sessions on a 3D codebase map
Original: Show HN: Mindwalk – Replay coding-agent sessions on a 3D map of your codebase
Why This Matters
Debugging and auditing AI coding-agent behavior is a growing need as agentic dev tools proliferate.
Mindwalk is an open-source visualization tool by cosmtrek that replays coding-agent sessions on an interactive 3D map of a codebase, helping developers see how AI agents navigated and understood their repositories. The project has earned 268 GitHub stars since launch.
Mindwalk, published on GitHub by developer cosmtrek, is an open-source tool that transforms coding-agent session logs into 3D visual replays mapped onto a repository's file structure. The tool addresses a gap in AI-assisted development: while session logs (typically JSONL format) record what an agent did, they offer no intuitive view of how it reasoned—which files it treated as relevant, where it explored before acting, or whether its scope matched developer intent. Mindwalk renders the repository as a 'night map' and animates the agent's activity as light moving through it, visualizing search paths, file reads, and edits in sequence. The project is written in Go and includes a web-based frontend. It supports agent frameworks that produce structured session logs. As of publication, the repository has 268 stars and 10 forks on GitHub, and includes dedicated configuration files for Claude (CLAUDE.md) and general agents (AGENTS.md), suggesting compatibility with multiple AI coding assistants.
