Only turn end and the moments needing the user should signal. Any other event reaching the hook, such as agent_completed or auth_success, now exits without emitting, so a subagent finishing rings nothing even if the Notification matcher is ignored.

# Notification + Stop hook — signal the user through the terminal when
|
|
# Claude needs input (permission, question, idle wait) or has finished
|
|
# responding. Each case gets its own readable label so the toast says
|
|
# which one fired.
|
|
#
|
|
# Runs on the remote (Linux); the only channel that crosses SSH into the
|
|
# VS Code client is the terminal stream. Hooks have no controlling TTY,
|
|
# so the sequence goes through the supported `terminalSequence` JSON
|
|
# output field and Claude Code writes it to the terminal:
|
|
# - BEL x2 (double beep) -> sound, needs VS Code setting
|
|
# accessibility.signals.terminalBell { "sound": "on" } AND a non-zero
|
|
# volume for Code in the Windows volume mixer (BLK-020).
|
|
# - OSC 777 notify -> Windows toast via the client-side extension
|
|
# "Terminal Notification" (wenbopan.vscode-terminal-osc-notifier).
|
|
# A terminal can be deaf to OSC while the bell still rings; test it
|
|
# before attaching a session to it (LRN-148).
|
|
# Both are invisible no-ops in terminals that ignore them.
