Mindwalk: A Tool to Visualize Coding Agent Sessions as a 3D Codebase Map

·2026.07.19 09:31

Key point

A new tool called 'Mindwalk' visualizes a coding agent's task context as a 3D night map, revealing exploration and modification processes that logs alone couldn't show.

Details

Existing coding agent session logs record the work performed itself, but fail to reveal how the agent understood the task (judging relevant areas, where it explored, whether it matched the scope of work), making this difficult to grasp from raw JSONL alone.

Mindwalk is a tool built to overcome this limitation by visualizing the repository as a night map. Locations where the agent searched, read, or modified code are lit up, while the rest of the areas remain dark, allowing an intuitive view of the agent's workflow and the scope of its activity within the codebase.
