cto-fleet-upgrade

Preamble (run first)

_UPD=$(~/.claude/skills/cto-fleet/bin/cto-fleet-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/cto-fleet/cto-fleet-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running cto-fleet v{to} (just updated!)" and continue.

/cto-fleet-upgrade

Upgrade cto-fleet to the latest version and show what's new.

Inline upgrade flow

This section is referenced by skill preambles when they detect UPGRADE_AVAILABLE.

Step 1: Ask the user (or auto-upgrade)

First, check if auto-upgrade is enabled:

_AUTO=""
[ "${CTO_FLEET_AUTO_UPGRADE:-}" = "1" ] && _AUTO="true"
[ -z "$_AUTO" ] && _AUTO=$(~/.claude/skills/cto-fleet/bin/cto-fleet-config get auto_upgrade 2>/dev/null || true)
echo "AUTO_UPGRADE=$_AUTO"

If AUTO_UPGRADE=true or AUTO_UPGRADE=1: Skip AskUserQuestion. Log "Auto-upgrading cto-fleet v{old} → v{new}..." and proceed directly to Step 2.

Otherwise, use AskUserQuestion:

• Question: "cto-fleet v{new} is available (you're on v{old}). Upgrade now?"
• Options: ["Yes, upgrade now", "Always keep me up to date", "Not now", "Never ask again"]

If "Yes, upgrade now": Proceed to Step 2.

If "Always keep me up to date":

~/.claude/skills/cto-fleet/bin/cto-fleet-config set auto_upgrade true

Tell user: "Auto-upgrade enabled. Future updates will install automatically." Then proceed to Step 2.

If "Not now": Write snooze state with escalating backoff (first snooze = 24h, second = 48h, third+ = 1 week), then continue with the current skill.

_SNOOZE_FILE=~/.cto-fleet/update-snoozed
_REMOTE_VER="{new}"
_CUR_LEVEL=0
if [ -f "$_SNOOZE_FILE" ]; then
  _SNOOZED_VER=$(awk '{print $1}' "$_SNOOZE_FILE")
  if [ "$_SNOOZED_VER" = "$_REMOTE_VER" ]; then
    _CUR_LEVEL=$(awk '{print $2}' "$_SNOOZE_FILE")
    case "$_CUR_LEVEL" in *[!0-9]*) _CUR_LEVEL=0 ;; esac
  fi
fi
_NEW_LEVEL=$((_CUR_LEVEL + 1))
[ "$_NEW_LEVEL" -gt 3 ] && _NEW_LEVEL=3
echo "$_REMOTE_VER $_NEW_LEVEL $(date +%s)" > "$_SNOOZE_FILE"

Note: {new} is the remote version from the UPGRADE_AVAILABLE output — substitute it from the update check result.
