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

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

cd ~/.claude/SASAMClaudeCodeSkills ./register-commands.sh

Step 5: Update Marketplace Clone

cd ~/.claude/plugins/marketplaces/SASAMClaudeCodeSkills git pull origin main

Step 6: Regenerate Manifest

cd ~/.claude/SASAMClaudeCodeSkills ./generate-manifest.sh
