🔴 BLOCKED — Read on claude-brainrot images is forbidden in CLI mode.

Read silently returns base64 image bytes; the USER SEES NOTHING. You must use the show.sh wrapper instead, which opens the image in Quick Look for ~3s and auto-closes:

    Bash $SHOW_SCRIPT "$FILE_PATH"

The PostToolUse hook will extract the image path from that bash command and fire the paired sound automatically. Retry your image emit using show.sh.
