/ostack-upgrade

Upgrade ostack 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:

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

If AUTO_UPGRADE=true or AUTO_UPGRADE=1: Skip AskUserQuestion. Log "Auto-upgrading ostack 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 /ostack-upgrade manually to retry."

Otherwise, use AskUserQuestion:

• Question: "ostack 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/ostack/bin/ostack-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.

_SNOOZE_FILE=~/.ostack/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 ~/.ostack/config.yaml for automatic upgrades."

If "Never ask again":

~/.claude/skills/ostack/bin/ostack-config set update_check false

Tell user: "Update checks disabled. Run ~/.claude/skills/ostack/bin/ostack-config set update_check true to re-enable." Continue with the current skill.

Step 2: Detect install type

if [ -d "$HOME/.claude/skills/ostack/.git" ]; then
  INSTALL_TYPE="global-git"
  INSTALL_DIR="$HOME/.claude/skills/ostack"
elif [ -d "$HOME/.ostack/repos/ostack/.git" ]; then
  INSTALL_TYPE="global-git"
  INSTALL_DIR="$HOME/.ostack/repos/ostack"
elif [ -d ".claude/skills/ostack/.git" ]; then
  INSTALL_TYPE="local-git"
  INSTALL_DIR=".claude/skills/ostack"
elif [ -d ".agents/skills/ostack/.git" ]; then
  INSTALL_TYPE="local-git"
  INSTALL_DIR=".agents/skills/ostack"
elif [ -d ".claude/skills/ostack" ]; then
  INSTALL_TYPE="vendored"
  INSTALL_DIR=".claude/skills/ostack"
elif [ -d "$HOME/.claude/skills/ostack" ]; then
  INSTALL_TYPE="vendored-global"
  INSTALL_DIR="$HOME/.claude/skills/ostack"
else
  echo "ERROR: ostack 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:

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):

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):

PARENT=$(dirname "$INSTALL_DIR")
TMP_DIR=$(mktemp -d)
git clone --depth 1 https://github.com/mr-daedalium/ostack.git "$TMP_DIR/ostack"
mv "$INSTALL_DIR" "$INSTALL_DIR.bak"
mv "$TMP_DIR/ostack" "$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:

_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
LOCAL_OSTACK=""
if [ -n "$_ROOT" ] && [ -d "$_ROOT/.claude/skills/ostack" ]; then
  _RESOLVED_LOCAL=$(cd "$_ROOT/.claude/skills/ostack" && pwd -P)
  _RESOLVED_PRIMARY=$(cd "$INSTALL_DIR" && pwd -P)
  if [ "$_RESOLVED_LOCAL" != "$_RESOLVED_PRIMARY" ]; then
    LOCAL_OSTACK="$_ROOT/.claude/skills/ostack"
  fi
fi
echo "LOCAL_OSTACK=$LOCAL_OSTACK"

If LOCAL_OSTACK is non-empty, update it by copying from the freshly-upgraded primary install (same approach as README vendored install):

mv "$LOCAL_OSTACK" "$LOCAL_OSTACK.bak"
cp -Rf "$INSTALL_DIR" "$LOCAL_OSTACK"
rm -rf "$LOCAL_OSTACK/.git"
cd "$LOCAL_OSTACK" && ./setup
rm -rf "$LOCAL_OSTACK.bak"

Tell user: "Also updated vendored copy at $LOCAL_OSTACK — commit .claude/skills/ostack/ when you're ready."

If ./setup fails, restore from backup and warn the user:

rm -rf "$LOCAL_OSTACK"
mv "$LOCAL_OSTACK.bak" "$LOCAL_OSTACK"

Tell user: "Sync failed — restored previous version at $LOCAL_OSTACK. Run /ostack-upgrade manually to retry."

Step 5: Write marker + clear cache

mkdir -p ~/.ostack
echo "$OLD_VERSION" > ~/.ostack/just-upgraded-from
rm -f ~/.ostack/last-update-check
rm -f ~/.ostack/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:

ostack 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 /ostack-upgrade (not from a preamble):

1. Force a fresh update check (bypass cache):

~/.claude/skills/ostack/bin/ostack-update-check --force 2>/dev/null || \
.claude/skills/ostack/bin/ostack-update-check --force 2>/dev/null || true

Use the output to determine if an upgrade is available.

2. If UPGRADE_AVAILABLE <old> <new>: follow Steps 2-6 above.

3. If no output (primary is up to date): check for a stale local vendored copy.

Run the Step 2 bash block above to detect the primary install type and directory (INSTALL_TYPE and INSTALL_DIR). Then run the Step 4.5 detection bash block above to check for a local vendored copy (LOCAL_OSTACK).

If LOCAL_OSTACK is empty (no local vendored copy): tell the user "You're already on the latest version (v{version})."

If LOCAL_OSTACK is non-empty, compare versions:

PRIMARY_VER=$(cat "$INSTALL_DIR/VERSION" 2>/dev/null || echo "unknown")
LOCAL_VER=$(cat "$LOCAL_OSTACK/VERSION" 2>/dev/null || echo "unknown")
echo "PRIMARY=$PRIMARY_VER LOCAL=$LOCAL_VER"

If versions differ: follow the Step 4.5 sync bash block above to update the local copy from the primary. Tell user: "Global v{PRIMARY_VER} is up to date. Updated local vendored copy from v{LOCAL_VER} → v{PRIMARY_VER}. Commit .claude/skills/ostack/ when you're ready."

If versions match: tell the user "You're on the latest version (v{PRIMARY_VER}). Global and local vendored copy are both up to date."
