# Traceability Hook
#
# Claude Code hook that runs after key tool calls to provide
# context-aware reminders for documentation and traceability.
#
# Covers: journaling, task notes, progress updates, KB search,
# communication, verification checks.
#
# This hook is non-blocking and always succeeds to avoid
# interrupting Claude's workflow.
