From 4c369a62c3cfa417ddf4bd5346398b885d38e6b4 Mon Sep 17 00:00:00 2001 From: Ryan Bonial Date: Wed, 28 Jan 2026 12:52:52 -0700 Subject: [PATCH] fix: prevent false success detection when Claude interrupted before real work Add timestamp-based commit verification to detect only commits made during current iteration. Previously, Ralph would detect old merge commits and report success even when Claude was interrupted immediately without completing any work. Changes: - Add ITERATION_START_TIME variable captured before execute_agent() - Get commit timestamp using git log --format=%ct - Only report success if commit timestamp > iteration start time - Add warning for commits from previous work - Apply fix to both run_single_iteration() and run_continuous_loop() - Create comprehensive test suite (12 tests) following TDD workflow Co-Authored-By: Claude Sonnet 4.5 --- .ralph/prd.json | 9 ++- .ralph/progress.txt | 59 +++++++++++++++++++ ralph.sh | 94 ++++++++++++++++++++----------- tests/ralph-commit-detection.bats | 78 +++++++++++++++++++++++++ 4 files changed, 205 insertions(+), 35 deletions(-) create mode 100644 tests/ralph-commit-detection.bats diff --git a/.ralph/prd.json b/.ralph/prd.json index 8154551..01c431c 100644 --- a/.ralph/prd.json +++ b/.ralph/prd.json @@ -737,9 +737,12 @@ "depends_on": [ "000" ], -
