Arcturn Makes Coding Agents Show Their Work

arcturn.dev Observed source
Editorial interest 84/100 Selection signal · not a rating of the site

An open-source terminal coding agent that puts permissions, snapshots, and replayable session history around every tool call.

Landing page captured for the 2026-08-25 issue.

Field notes

The displayed workflow separates exploration from modification: the agent reads a route and searches for existing validation before stopping at a permission prompt. The prompt offers session-relevant choices, including a project-scoped rule for future edits to the file. The site says sessions persist as append-only trees, allowing /rewind to fork the conversation and restore files without deleting the prior path. The example identifies the model, working directory, token context, elapsed time, and cost.
