/gstack-upgrade

Upgrade gstack to the latest version and show what's new.

Inline upgrade flow

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

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

First, check if auto-upgrade is enabled:
bash
_AUTO=""
[ "${GSTACK_AUTO_UPGRADE:-}" = "1" ] && _AUTO="true"
[ -z "$_AUTO" ] && _AUTO=$(~/.claude/skills/gstack/bin/gstack-config get auto_upgrade 2>/dev/null || true)
echo "AUTO_UPGRADE=$_AUTO"
If 
AUTO_UPGRADE=true
or 
AUTO_UPGRADE=1
: Skip AskUserQuestion. Log "Auto-upgrading gstack v{old} → v{new}..." and proceed directly to Step 2. If 
./setup
fails during auto-upgrade, restore from backup (
.bak
directory) and warn the user: "Auto-upgrade failed — restored previous version. Run 
/gstack-upgrade
manually to retry."
Otherwise, use AskUserQuestion:
  • Question: "gstack 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":
bash
~/.claude/skills/gstack/bin/gstack-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. Do not mention the upgrade again.
bash
_SNOOZE_FILE=~/.gstack/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.
Tell user the snooze duration: "Next reminder in 24h" (or 48h or 1 week, depending on level). Tip: "Set 
auto_upgrade: true
in 
~/.gstack/config.yaml
for automatic upgrades."
If "Never ask again":
bash
~/.claude/skills/gstack/bin/gstack-config set update_check false
Tell user: "Update checks disabled. Run 
~/.claude/skills/gstack/bin/gstack-config set update_check true
to re-enable." Continue with the current skill.

Step 2: Detect install type

bash
if [ -d "$HOME/.claude/skills/gstack/.git" ]; then
  INSTALL_TYPE="global-git"
  INSTALL_DIR="$HOME/.claude/skills/gstack"
elif [ -d ".claude/skills/gstack/.git" ]; then
  INSTALL_TYPE="local-git"
  INSTALL_DIR=".claude/skills/gstack"
elif [ -d ".claude/skills/gstack" ]; then
  INSTALL_TYPE="vendored"
  INSTALL_DIR=".claude/skills/gstack"
elif [ -d "$HOME/.claude/skills/gstack" ]; then
  INSTALL_TYPE="vendored-global"
  INSTALL_DIR="$HOME/.claude/skills/gstack"
else
  echo "ERROR: gstack not found"
  exit 1
fi
echo "Install type: $INSTALL_TYPE at $INSTALL_DIR"
The install type and directory path printed above will be used in all subsequent steps.

Step 3: Save old version

Use the install directory from Step 2's output below:
bash
OLD_VERSION=$(cat "$INSTALL_DIR/VERSION" 2>/dev/null || echo "unknown")

Step 4: Upgrade

Use the install type and directory detected in Step 2:
For git installs (global-git, local-git):
bash
cd "$INSTALL_DIR"
STASH_OUTPUT=$(git stash 2>&1)
git fetch origin
git reset --hard origin/main
./setup
If 
$STASH_OUTPUT
contains "Saved working directory", warn the user: "Note: local changes were stashed. Run 
git stash pop
in the skill directory to restore them."
For vendored installs (vendored, vendored-global):
bash
PARENT=$(dirname "$INSTALL_DIR")
TMP_DIR=$(mktemp -d)
git clone --depth 1 https://github.com/garrytan/gstack.git "$TMP_DIR/gstack"
mv "$INSTALL_DIR" "$INSTALL_DIR.bak"
mv "$TMP_DIR/gstack" "$INSTALL_DIR"
cd "$INSTALL_DIR" && ./setup
rm -rf "$INSTALL_DIR.bak" "$TMP_DIR"

Step 4.5: Sync local vendored copy

Use the install directory from Step 2. Check if there's also a local vendored copy that needs updating:
bash
_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
LOCAL_GSTACK=""
if [ -n "$_ROOT" ] && [ -d "$_ROOT/.claude/skills/gstack" ]; then
  _RESOLVED_LOCAL=$(cd "$_ROOT/.claude/skills/gstack" && pwd -P)
  _RESOLVED_PRIMARY=$(cd "$INSTALL_DIR" && pwd -P)
  if [ "$_RESOLVED_LOCAL" != "$_RESOLVED_PRIMARY" ]; then
    LOCAL_GSTACK="$_ROOT/.claude/skills/gstack"
  fi
fi
echo "LOCAL_GSTACK=$LOCAL_GSTACK"
If 
LOCAL_GSTACK
is non-empty, update it by copying from the freshly-upgraded primary install (same approach as README vendored install):
bash
mv "$LOCAL_GSTACK" "$LOCAL_GSTACK.bak"
cp -Rf "$INSTALL_DIR" "$LOCAL_GSTACK"
rm -rf "$LOCAL_GSTACK/.git"
cd "$LOCAL_GSTACK" && ./setup
rm -rf "$LOCAL_GSTACK.bak"
Tell user: "Also updated vendored copy at 
$LOCAL_GSTACK
— commit 
.claude/skills/gstack/
when you're ready."

Step 5: Write marker + clear cache

bash
mkdir -p ~/.gstack
echo "$OLD_VERSION" > ~/.gstack/just-upgraded-from
rm -f ~/.gstack/last-update-check
rm -f ~/.gstack/update-snoozed

Step 6: Show What's New

Read 
$INSTALL_DIR/CHANGELOG.md
. Find all version entries between the old version and the new version. Summarize as 5-7 bullets grouped by theme. Don't overwhelm — focus on user-facing changes. Skip internal refactors unless they're significant.
Format:
gstack v{new} — upgraded from v{old}!

What's new:
- [bullet 1]
- [bullet 2]
- ...

Happy shipping!

Step 7: Continue

After showing What's New, continue with whatever skill the user originally invoked. The upgrade is done — no further action needed.

Standalone usage

When invoked directly as 
/gstack-upgrade
(not from a preamble):
  1. Force a fresh update check (bypass cache):
bash
~/.claude/skills/gstack/bin/gstack-update-check --force
Use the output to determine if an upgrade is available.
  1. If 
    UPGRADE_AVAILABLE <old> <new>
    : follow Steps 2-6 above.
  2. If no output (up to date): tell the user "You're already on the latest version (v{version})."
