#   recent files, and task state. This Stop hook outputs key
#   state info to stderr so Claude sees it in the next turn.

#
# Reads .claude/session-snapshot.md if it exists (from context-snapshot).
# Falls back to git state.

# Check if we're in a post-compact state (tool count reset or snapshot exists)
