Nano Banana Image Editor Plugin Upgrade

You are running the nano-banana-image-editor upgrade command to update the plugin to the latest version.

Your Task

Guide the user through upgrading the nano-banana-image-editor plugin by pulling the latest changes from the marketplace repository.

Workflow

Step 1: Verify Current Installation

Check the current version and installation location:

# Get marketplace directory
MARKETPLACE_DIR=$(dirname $(dirname ${CLAUDE_PLUGIN_ROOT}))

# Get current version from marketplace.json
CURRENT_VERSION=$(jq -r '.plugins[] | select(.name=="nano-banana-image-editor") | .version' "$MARKETPLACE_DIR/.claude-plugin/marketplace.json")

# Verify git repository
cd "$MARKETPLACE_DIR" && git rev-parse --git-dir >/dev/null 2>&1 && echo "✓ Git repository found" || echo "✗ Not a git repository"

Output to user:

Current version: [version]
Marketplace directory: [path]

Step 2: Check for Updates

Fetch the latest tags and check for updates:

cd "$MARKETPLACE_DIR"
git fetch --tags origin

Then get the version information:

# Get the latest version tag for this plugin
LATEST_TAG=$(git tag -l 'nano-banana-image-editor/v*' --sort=-v:refname | head -n 1)

# Get current tag (if on a tag)
CURRENT_TAG=$(git describe --tags --exact-match 2>/dev/null || echo "none")

# Filter to only nano-banana-image-editor tags if we're on a tag
if [ "$CURRENT_TAG" != "none" ]; then
  echo "$CURRENT_TAG" | grep -q '^nano-banana-image-editor/' || CURRENT_TAG="none"
fi

echo "Latest tag: $LATEST_TAG"
echo "Current tag: $CURRENT_TAG"

Analyze the output:

• If LATEST_TAG is empty → No tagged releases available yet
• If CURRENT_TAG equals LATEST_TAG → Already on latest version
• If LATEST_TAG is newer → Continue to Step 3
• If git fetch fails → Inform user there's a connection issue

Output to user:

Current version: [CURRENT_VERSION] (tag: [CURRENT_TAG or "not on a tagged release"])
Latest available: [LATEST_TAG]
