Ralph Loop

Ralph Loop runs Claude on a loop that reads its previous output, test results, and git history, then makes targeted edits on the next pass. It captures file diffs, commit messages, and failing tests so each iteration starts from the exact state of the last run. The plugin watches the repo, records state, and feeds concrete failure information back into the prompt so changes become focused and incremental instead of redoing work from scratch.

On each cycle Ralph Loop runs the same test suite, parses failures, and applies edits or new commits. You can configure iteration limits, stop conditions, and which files to protect. The plugin stores every intermediate commit and exposes the chain of changes, so you can review why a particular fix was attempted and revert or cherry-pick any step.

Ralph Loop connects to your local or remote git host, pushes commits, and preserves branch history. It annotates commits with the test output that triggered them and provides a clear loop log. You keep full control: approve or reject commits, force a different strategy, or inject a human note between passes.

In practice this saves time when fixing flaky tests or iterating on a feature: instead of copying failures into a new tool and re-running builds manually, Ralph Loop keeps the context, runs tests, and updates code until tests pass or you stop it — no tool switching or lost debug state.
