From d3310d1f3f150e3738e7528aaa4dca8a03d49b13 Mon Sep 17 00:00:00 2001 From: Test User Date: Sat, 10 Jan 2026 10:27:42 -0700 Subject: [PATCH] feat(session): add session lifecycle management with auto-reset triggers - Add session management functions: get_session_id(), reset_session(), log_session_transition(), init_session_tracking() - Session auto-reset on: circuit breaker open, manual interrupt, project completion, manual circuit reset - Add --reset-session CLI flag for manual session reset - Add session history tracking (.ralph_session_history, last 50 entries) - New config: RALPH_SESSION_FILE, RALPH_SESSION_HISTORY_FILE - Add 26 comprehensive tests for session continuity (TDD) - All 265 tests pass (up from 239) - Update CLAUDE.md with v0.9.7 release notes --- CLAUDE.md | 28 +- ralph_loop.sh | 143 ++++++++- tests/unit/test_session_continuity.bats | 369 ++++++++++++++++++++++++ 3 files changed, 536 insertions(+), 4 deletions(-) create mode 100644 tests/unit/test_session_continuity.bats diff --git a/CLAUDE.md b/CLAUDE.md index 418161e..b099ac2 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -6,7 +6,7 @@ This file provides guidance to Claude Code (claude.ai/code) when working with co This is the Ralph for Claude Code repository -
