When working with AI agents, fear of regressions is constant. What happens when an agent hallucinates, modifies files outside the target scope, or introduces a subtle bug? In traditional editors, you are forced to manually run git stash, git diff, or git reset --hard, risking uncommitted work.
Ensembyte records shadow Git commits completely in the background without touching your working tree HEAD. Before and after any agent modifies files, a cryptographic snapshot of the working tree is stored in our private ref namespace.
# Ensembyte shadow checkpoint creation under the hood:
# 1. Write the tree directly to the git object database
TREE_SHA=$(git write-tree)
# 2. Record turn metadata without moving active HEAD or branch
COMMIT_SHA=$(git commit-tree $TREE_SHA -p HEAD -m "ensembyte:turn-18")
git update-ref refs/ensembyte/checkpoints/turn-18 $COMMIT_SHA
# 3. Instant revert is simply a 3-way tree checkout!This architecture guarantees that every single turn in your conversation has a built-in diff viewer and a one-click rollback button. If you dislike a change, press "Revert Turn" and your working tree restores instantly.
Want to experiment with a completely different architecture while your current thread is running? Click "New Thread in Worktree". Ensembyte instantly creates an independent checkout on disk on a new branch. You can run two completely different agents on two separate branches at the exact same time without file locks.
