Upgrade superskills to the latest version.

Steps

Step 1: Find the install directory

Two install shapes are supported:

• Canonical install — the repo is cloned at ~/.claude/skills/superskills (or the OpenCode equivalent) and ./setup ran from there.
• Dev-repo install — the repo lives somewhere else (e.g. ~/Sites/superskills) and ./setup symlinked the skills back into the tools. Common for maintainers and contributors. There is no clone under ~/.claude/skills/superskills; we recover the real repo by resolving a skill symlink back to its source.

INSTALL_DIR=""
INSTALL_KIND=""

if [ -d "$HOME/.claude/skills/superskills/.git" ]; then
  INSTALL_DIR="$HOME/.claude/skills/superskills"; INSTALL_KIND="canonical"
elif [ -d "$HOME/.config/opencode/skills/superskills/.git" ]; then
  INSTALL_DIR="$HOME/.config/opencode/skills/superskills"; INSTALL_KIND="canonical"
else
  # Dev-repo install: follow a known skill symlink back to its source checkout.
  for probe in "$HOME/.claude/skills/superskills-upgrade/SKILL.md" \
               "$HOME/.config/opencode/skills/superskills-upgrade/SKILL.md"; do
    [ -L "$probe" ] || continue
    target=$(readlink "$probe")
    # Resolve relative symlink targets against the link's own directory.
    case "$target" in /*) : ;; *) target="$(dirname "$probe")/$target" ;; esac
    root=$(git -C "$(dirname "$target")" rev-parse --show-toplevel 2>/dev/null) || continue
    if [ -f "$root/setup" ] && [ -f "$root/VERSION" ]; then
      INSTALL_DIR="$root"; INSTALL_KIND="dev-repo"; break
    fi
  done
fi

if [ -z "$INSTALL_DIR" ]; then
  echo "ERROR: superskills git install not found"
  echo "Expected a clone at $HOME/.claude/skills/superskills, or skills symlinked from a source checkout."
  echo "Re-install: git clone https://github.com/ariadoss/superskills.git ~/.claude/skills/superskills && cd ~/.claude/skills/superskills && ./setup"
  exit 1
fi
echo "INSTALL_DIR=$INSTALL_DIR"
echo "INSTALL_KIND=$INSTALL_KIND"
REMOTE_URL=$(git -C "$INSTALL_DIR" remote get-url origin 2>/dev/null || echo "unknown")
echo "REMOTE_URL=$REMOTE_URL"

Step 2: Record current version

OLD_VERSION=$(cat "$INSTALL_DIR/VERSION" 2>/dev/null | tr -d '[:space:]' || echo "unknown")
echo "Current version: $OLD_VERSION"

Step 3: Sync to latest and re-run setup

Behavior depends on INSTALL_KIND:

• canonical — a managed clone the user doesn't develop in. Written to always land on origin/main, even if history was rewritten/force-pushed or the user edited skills in place. A plain git pull --ff-only is not enough (it aborts on divergence and on local modifications), so a hard-reset fallback guarantees the sync.
• dev-repo — the user's own working checkout. Treated gently: never hard-reset and never discard commits. Only uncommitted changes are stashed around a clean fast-forward; if the branch has diverged, stop and let the user resolve it by hand.

cd "$INSTALL_DIR"
git fetch origin
REMOTE_VERSION=$(git show origin/main:VERSION 2>/dev/null | tr -d '[:space:]' || echo "unknown")
echo "Remote version: $REMOTE_VERSION"

if [ "$OLD_VERSION" = "$REMOTE_VERSION" ] && [ "$REMOTE_VERSION" != "unknown" ]; then
  echo "ALREADY_LATEST=true"
  # Still re-link in case new skills were added within the same version.
  ./setup -q
else
  # Preserve uncommitted local edits so nothing is lost.
  STASHED=0
  if ! git diff --quiet || ! git diff --cached --quiet; then
    if git stash push -u -m "superskills-upgrade autostash" >/dev/null 2>&1; then
      STASHED=1
      echo "Stashed local changes before upgrade."
    fi
  fi

  # Try the clean fast-forward first (preserves local commits if any).
  if git pull --ff-only origin main 2>/dev/null; then
    echo "SYNC=fast-forward"
  elif [ "$INSTALL_KIND" = "dev-repo" ]; then
    # Maintainer's working repo — do NOT discard their commits.
    echo "SYNC=diverged-dev"
    echo "Your dev checkout has diverged from origin/main and can't fast-forward."
    echo "Resolve manually (e.g. 'git rebase origin/main' or 'git merge origin/main'), then re-run ./setup."
    [ "$STASHED" = "1" ] && git stash pop >/dev/null 2>&1 && echo "Restored stashed changes."
    exit 0
  else
    # Canonical install — force-match origin/main (handles force-pushed history).
    echo "Fast-forward not possible; resetting to origin/main."
    git reset --hard origin/main
    echo "SYNC=reset"
  fi

  # Re-apply stashed edits; if they conflict, leave them in the stash.
  if [ "$STASHED" = "1" ]; then
    if git stash pop >/dev/null 2>&1; then
      echo "Re-applied stashed local changes."
    else
      echo "STASH_CONFLICT=true  (your edits are safe in 'git stash list')"
    fi
  fi

  ./setup -q
  NEW_VERSION=$(cat "$INSTALL_DIR/VERSION" 2>/dev/null | tr -d '[:space:]' || echo "unknown")
  echo "NEW_VERSION=$NEW_VERSION"
fi

Step 4: Report result

If ALREADY_LATEST=true: Tell the user:

superskills is already up to date (v{OLD_VERSION}).

If upgrade ran: Tell the user:

superskills upgraded: v{OLD_VERSION} → v{NEW_VERSION}

If OLD_VERSION equals NEW_VERSION, note that setup was re-run but the version didn't change (may have picked up skill updates within the same version).

If SYNC=reset appeared: the local clone had diverged from upstream (usually because published history was rewritten). It was force-matched to origin/main. If the user had local commits, those were discarded — only uncommitted edits are auto-preserved. (Only happens for a canonical install.)

If SYNC=diverged-dev appeared: this is a dev-repo install (the user's own checkout) that has commits not on origin/main, so it can't fast-forward. Nothing was discarded. Tell the user to reconcile their branch themselves, then re-run setup:

cd "$INSTALL_DIR" && git rebase origin/main   # or: git merge origin/main
cd "$INSTALL_DIR" && ./setup -q

(use the INSTALL_DIR value from Step 1)

If STASH_CONFLICT=true appeared: the user's local edits couldn't be re-applied cleanly on top of the new version. Their changes are safe — tell them to recover with:

cd "$INSTALL_DIR" && git stash list   # find the 'superskills-upgrade autostash' entry
cd "$INSTALL_DIR" && git stash pop     # or: git stash show -p stash@{0} to inspect

(use the INSTALL_DIR value from Step 1)
