Upgrade Claude Code to the latest version - sends /exit, waits for exit, upgrades, and lets activity-monitor restart.
Before launching the upgrade script, complete these steps in order:
Check for running background agents (Task tool). If any are active, stop them to avoid orphaned work.
Update memory files (state.md, sessions/current.md, etc.) to preserve important context that would otherwise be lost on restart.
Write a brief message covering:
Send the full handoff summary to the internal web console channel via C4:
cat <<'EOF' | node ~/zylos/.claude/skills/comm-bridge/scripts/c4-send.js "web-console" "session-handoff"
<handoff summary>
EOF
This records the handoff in C4 conversation history so the upgraded session's
startup hook (c4-session-init) can include it in startup context.
Do not send the full handoff summary to the active external user channel
(Telegram, Lark, Feishu, HXA, etc.). Handoff summaries are operational context
for the next agent session and may contain task state from outside the current
conversation. If the user is actively waiting, send only a short user-facing
notice to their current reply via path, without internal task inventory or
cross-channel context.
IMPORTANT: Must use nohup ... & pattern!
nohup node ~/zylos/.claude/skills/upgrade-claude/scripts/upgrade.js >> ~/zylos/logs/upgrade.log 2>&1 &
