/featureforge-upgrade

Upgrade FeatureForge to the latest version and summarize what changed.

Inline upgrade flow

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

Step 1: Resolve install root

Reuse the already selected runtime root when it is available. Otherwise resolve the active install once through the packaged install binary and reuse it for the rest of the flow:

_FEATUREFORGE_INSTALL_ROOT="$HOME/.featureforge/install"
FEATUREFORGE_RUNTIME_BIN="${_FEATUREFORGE_BIN:-}"
INSTALL_DIR="${_FEATUREFORGE_ROOT:-}"
UPGRADE_ELIGIBLE=""
INSTALL_RUNTIME_BIN=""

_FEATUREFORGE_INSTALL_RUNTIME_BIN() {
  if [ -x "$INSTALL_DIR/bin/featureforge" ]; then
    printf '%s\n' "$INSTALL_DIR/bin/featureforge"
    return 0
  fi
  if [ -f "$INSTALL_DIR/bin/featureforge.exe" ]; then
    printf '%s\n' "$INSTALL_DIR/bin/featureforge.exe"
    return 0
  fi
  return 1
}

if [ -z "$FEATUREFORGE_RUNTIME_BIN" ]; then
  if [ -x "$_FEATUREFORGE_INSTALL_ROOT/bin/featureforge" ]; then
    FEATUREFORGE_RUNTIME_BIN="$_FEATUREFORGE_INSTALL_ROOT/bin/featureforge"
  elif [ -f "$_FEATUREFORGE_INSTALL_ROOT/bin/featureforge.exe" ]; then
    FEATUREFORGE_RUNTIME_BIN="$_FEATUREFORGE_INSTALL_ROOT/bin/featureforge.exe"
  fi
fi

if [ -z "$FEATUREFORGE_RUNTIME_BIN" ] || { [ ! -x "$FEATUREFORGE_RUNTIME_BIN" ] && [ ! -f "$FEATUREFORGE_RUNTIME_BIN" ]; }; then
  echo "ERROR: featureforge runtime-root helper unavailable"
  exit 1
fi

if [ -z "$INSTALL_DIR" ]; then
  if ! INSTALL_DIR=$("$FEATUREFORGE_RUNTIME_BIN" repo runtime-root --path 2>/dev/null); then
    echo "ERROR: featureforge runtime-root helper unavailable"
    exit 1
  fi
fi

if [ -z "$INSTALL_DIR" ]; then
  echo "ERROR: featureforge runtime root unavailable"
  exit 1
fi

if ! INSTALL_RUNTIME_BIN=$(_FEATUREFORGE_INSTALL_RUNTIME_BIN); then
  echo "ERROR: featureforge runtime root returned no executable featureforge binary"
  exit 1
fi

if ! UPGRADE_ELIGIBLE=$(FEATUREFORGE_DIR="$INSTALL_DIR" "$FEATUREFORGE_RUNTIME_BIN" repo runtime-root --field upgrade-eligible 2>/dev/null); then
  echo "ERROR: featureforge runtime-root helper unavailable"
  exit 1
fi

if [ "$UPGRADE_ELIGIBLE" != "true" ]; then
  echo "ERROR: featureforge runtime root is not upgrade-eligible"
  exit 1
fi

echo "INSTALL_DIR=$INSTALL_DIR"
echo "FEATUREFORGE_RUNTIME_BIN=$FEATUREFORGE_RUNTIME_BIN"
echo "INSTALL_RUNTIME_BIN=$INSTALL_RUNTIME_BIN"
echo "UPGRADE_ELIGIBLE=$UPGRADE_ELIGIBLE"

Step 2: Resolve versions and auto-upgrade preference

Resolve the local and remote version before asking the user anything. This makes direct /featureforge-upgrade usage self-contained and uses the same remote source as featureforge update-check.

_COMPARE_FEATUREFORGE_VERSIONS() {
  local left="$1"
  local right="$2"
  local IFS=.
  local -a left_parts right_parts
  local max_parts=0
  local i left_value right_value

  read -r -a left_parts <<< "$left"
  read -r -a right_parts <<< "$right"

  if [ "${#left_parts[@]}" -gt "${#right_parts[@]}" ]; then
    max_parts="${#left_parts[@]}"
  else
    max_parts="${#right_parts[@]}"
  fi

  for ((i = 0; i < max_parts; i++)); do
    left_value="${left_parts[i]:-0}"
    right_value="${right_parts[i]:-0}"

    case "$left_value" in ''|*[!0-9]*) echo "unknown"; return 0 ;; esac
    case "$right_value" in ''|*[!0-9]*) echo "unknown";  0 ;; 

     ((# < #)); 
       
       0
    

     ((# > #)); 
       
       0
    
  

   
}

LOCAL_VERSION=
REMOTE_URL=
REMOTE_VERSION=
REMOTE_VERSION=

 !    | grep -qE ; 
  LOCAL_VERSION=


REMOTE_STATUS=
 !    | grep -qE ; 
  REMOTE_VERSION=
  REMOTE_STATUS=


VERSION_RELATION=
 [  !=  ] && [  =  ]; 
  VERSION_RELATION=


 
 
 
 

If REMOTE_STATUS=unavailable and this skill was invoked directly, stop before Step 3. Tell the user: FeatureForge couldn't verify the latest version right now. Try /featureforge-upgrade again in a moment.

If VERSION_RELATION=unknown and this skill was invoked directly, stop before Step 3. Tell the user: FeatureForge couldn't compare the local and remote versions right now. Check $INSTALL_DIR/VERSION and try again.

If VERSION_RELATION=equal, tell the user: You're already on the latest known version (v$LOCAL_VERSION).

If VERSION_RELATION=local_ahead, tell the user: Your local FeatureForge install (v$LOCAL_VERSION) is newer than the fetched remote version (v$REMOTE_VERSION).

If this skill was invoked from an UPGRADE_AVAILABLE handoff, the prompting layer already knows the display versions {old} and {new}. If the fresh fetch fails, keep using the handoff values and continue. If it was invoked directly, use v$LOCAL_VERSION and v$REMOTE_VERSION in the upgrade question below.

Only continue to auto-upgrade or the interactive question when VERSION_RELATION=upgrade, or when the skill entered from an UPGRADE_AVAILABLE handoff with known {old} and {new} display versions.

First, check if auto-upgrade is enabled:

_AUTO=""
[ "${FEATUREFORGE_AUTO_UPGRADE:-}" = "1" ] && _AUTO="true"
[ -z "$_AUTO" ] && _AUTO=$("$FEATUREFORGE_RUNTIME_BIN" config get auto_upgrade 2>/dev/null || true)
echo "AUTO_UPGRADE=$_AUTO"

Direct manual /featureforge-upgrade runs are explicit user intent, so they ignore update_check=false and any snooze state. They still honor auto_upgrade when a real newer version exists.

If AUTO_UPGRADE=true or AUTO_UPGRADE=1: skip the interactive question, log Auto-upgrading featureforge v{old} -> v{new}... (or Auto-upgrading featureforge v$LOCAL_VERSION -> v$REMOTE_VERSION... for direct invocation), and continue to Step 3.

Otherwise, ask one interactive user question:

• Question: featureforge v{new} is available (you're on v{old}). Upgrade now? For direct invocation, substitute v$REMOTE_VERSION and v$LOCAL_VERSION.
• Options: A) Yes, upgrade now B) Always keep me up to date C) Not now D) Never ask again

If "Yes, upgrade now": continue to Step 3.

If "Always keep me up to date":

"$FEATUREFORGE_RUNTIME_BIN" config set auto_upgrade true

Tell the user: Auto-upgrade enabled. Future updates will install automatically. Then continue to Step 3.

If "Not now": write snooze state with escalating backoff (24h, then 48h, then 1 week), then continue with the current skill.

_FEATUREFORGE_STATE_DIR="${FEATUREFORGE_STATE_DIR:-$HOME/.featureforge}"
_UPDATE_CHECK_DIR="$_FEATUREFORGE_STATE_DIR/update-check"
_SNOOZE_FILE="$_UPDATE_CHECK_DIR/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))
[ "$_NEW_LEVEL" -gt 3 ] && _NEW_LEVEL=3
mkdir -p "$_UPDATE_CHECK_DIR"
echo "$_REMOTE_VER $_NEW_LEVEL $(date +%s)" > "$_SNOOZE_FILE"

Tell the user the snooze duration and continue with the current skill.

If "Never ask again":

"$FEATUREFORGE_RUNTIME_BIN" config set update_check false

Tell the user: Update checks disabled. Run $FEATUREFORGE_RUNTIME_BIN config set update_check true to re-enable. Continue with the current skill.

Step 3: Save old version

OLD_VERSION=$(cat "$INSTALL_DIR/VERSION" 2>/dev/null || echo "unknown")

Step 4: Upgrade

cd "$INSTALL_DIR"
STASH_OUTPUT=$(git stash push --include-untracked -m "featureforge-upgrade-$(date +%Y%m%d-%H%M%S)" 2>&1 || true)
if ! git pull --ff-only; then
  echo "ERROR: featureforge upgrade failed during git pull"
  exit 1
fi
NEW_VERSION=$(cat "$INSTALL_DIR/VERSION" 2>/dev/null || echo "unknown")
echo "NEW_VERSION=$NEW_VERSION"

If $STASH_OUTPUT contains Saved working directory, warn the user that local changes were stashed and can be restored with git stash pop.

Step 5: Write marker and clear cache

_FEATUREFORGE_STATE_DIR="${FEATUREFORGE_STATE_DIR:-$HOME/.featureforge}"
_UPDATE_CHECK_DIR="$_FEATUREFORGE_STATE_DIR/update-check"
mkdir -p "$_UPDATE_CHECK_DIR"
rm -f "$_UPDATE_CHECK_DIR/last-update-check" "$_UPDATE_CHECK_DIR/update-snoozed"
if [ "$NEW_VERSION" != "$OLD_VERSION" ] && [ "$NEW_VERSION" != "unknown" ]; then
  echo "$OLD_VERSION" > "$_UPDATE_CHECK_DIR/just-upgraded-from"
fi

If NEW_VERSION is the same as OLD_VERSION, tell the user: No version change detected; already on the latest installed version (v$NEW_VERSION). Skip Step 6 and continue.

Step 6: Show What's New

Read $INSTALL_DIR/RELEASE-NOTES.md. Summarize the most relevant items between the old version and the new version as 5-7 short bullets grouped by theme. Prefer user-facing runtime and workflow changes over internal refactors.

Format:

featureforge v{new} — upgraded from v{old}!

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

Step 7: Continue

After the summary, continue with whatever skill the user originally invoked.

Standalone usage

When invoked directly as /featureforge-upgrade, run Steps 1-6 above. The skill must resolve LOCAL_VERSION, fetch REMOTE_VERSION, and stop before git pull unless REMOTE_VERSION is a valid newer version. If the remote lookup fails, tell the user FeatureForge could not verify the latest version right now. If the pull leaves NEW_VERSION unchanged, tell the user: You're already on the latest version (v$NEW_VERSION).
