find_file_pathsFind all file paths mentioned in conversations with their context

Session

5 tools — Session continuity & handoff

check_session_continuationDetect if there's recent work to continue from a previous session
get_continuation_contextGet full context (files, key points, pending work) for resuming
session_handoffSave and restore working memory for seamless session transitions
working_memoryActive reasoning state that persists across context compactions
update_active_workTrack current project state for instant recall on next session
