Update Check Workflow

Step 1: Read Local Version

LOCAL_VERSION=$(cat ~/.claude/SASAMClaudeCodeSkills/VERSION 2>/dev/null || echo "unknown")
echo "Local version: $LOCAL_VERSION"

Step 2: Fetch Remote Version

REMOTE_VERSION=$(curl -s "https://raw.githubusercontent.com/SAS-Asset-Management/SASAMClaudeCodeSkills/main/VERSION" 2>/dev/null || echo "error")
echo "Remote version: $REMOTE_VERSION"

Step 3: Compare Versions

if [ "$LOCAL_VERSION" = "$REMOTE_VERSION" ]; then
  echo "You are up to date (v$LOCAL_VERSION)"
else
  echo "Update available: $LOCAL_VERSION -> $REMOTE_VERSION"
fi

Changelog Workflow

Fetch and Display Changelog

# Fetch changelog from GitHub
CHANGELOG=$(curl -s "https://raw.githubusercontent.com/SAS-Asset-Management/SASAMClaudeCodeSkills/main/CHANGELOG.md")

# Display recent entries (first 50 lines)
echo "$CHANGELOG" | head -50

Apply Update Workflow

Step 1: Check for Local Modifications

Before updating, compare local files against the manifest to detect modifications:

cd ~/.claude/SASAMClaudeCodeSkills

# Load manifest
MANIFEST="sasam-file-manifest.json"

# Check each file against its stored hash
MODIFIED_FILES=()
while IFS= read -r file; do
  STORED_HASH=$(jq -r --arg f "$file" '.files[$f]' "$MANIFEST")
  CURRENT_HASH=$(shasum -a 256 "$file" 2>/dev/null | cut -d' ' -f1)

  if [ "$STORED_HASH" != "$CURRENT_HASH" ]; then
    MODIFIED_FILES+=("$file")
  fi
done < <(jq -r '.files | keys[]' "$MANIFEST")

if [ ${#MODIFIED_FILES[@]} -gt 0 ]; then
  echo "Modified files detected:"
  printf '  - %s\n' "${MODIFIED_FILES[@]}"
fi

Step 2: Backup Modified Files

BACKUP_DIR="sasam-local-patches/$(date +%Y%m%d_%H%M%S)"
mkdir -p "$BACKUP_DIR"

for file in "${MODIFIED_FILES[@]}"; do
  mkdir -p "$BACKUP_DIR/$(dirname "$file")"
  cp "$file" "$BACKUP_DIR/$file"
done

echo "Backed up ${#MODIFIED_FILES[@]} modified files to $BACKUP_DIR"

Step 3: Pull Updates

cd ~/.claude/SASAMClaudeCodeSkills
git pull origin main

Step 4: Re-register Commands

./register-commands.sh

Step 5: Update Marketplace Clone
