# Usage: ~/notify-session [message]
#
# Sends an iTerm2 notification that navigates to THIS tab when clicked.
# Works when called from Claude Code's Bash tool (which captures stdout).
#
# Examples:
#   ~/notify-session "PR comments addressed, ready for review"
#   ~/notify-session "Build complete"
#   ~/notify-session  # defaults to "Task complete"
#
# Writes directly to the tmux pane's TTY so the escape sequence reaches
# iTerm2 even when stdout is captured by Claude's Bash tool.

MESSAGE="${1:-Task complete}"
SESSION_NAME=$(tmux display-message -p '#S' 2>/dev/null || echo "Claude")

# Get the TTY of the current tmux pane
PANE_TTY=$(tmux display-message -p '#{pane_tty}' 2>/dev/null)

if [ -n "$PANE_TTY" ]; then
    # Write directly to the pane's TTY with tmux passthrough
    printf '\033Ptmux;\033\033]9;%s\007\033\\' "$MESSAGE" > "$PANE_TTY"
elif [ -n "$TMUX" ]; then
    # Fallback: we're in tmux but can't find pane TTY
    printf '\033Ptmux;\033\033]9;%s\007\033\\' "$MESSAGE"
else
    # Outside tmux: send OSC 9 directly
    printf '\033]9;%s\007' "$MESSAGE"
