Designer Extension

Create and develop Designer Extensions for Webflow with template selection, local development server, and bundling for distribution.

Important Note

ALWAYS use Bash tool for all Webflow CLI operations:

• Execute webflow extension commands via Bash tool
• Use Read tool to examine generated files and schema (never modify)
• Use Glob tool to discover project files
• Verify CLI installation: webflow --version
• Check authentication: webflow auth login (if needed)
• DO NOT use Webflow MCP tools for CLI workflows
• All CLI commands require proper descriptions (not context parameters)

Package Manager Detection:

• Check for lock files: package-lock.json (npm), pnpm-lock.yaml (pnpm), yarn.lock (yarn)
• If no lock file found, ask user which package manager to use (npm/pnpm/yarn)
• Use detected package manager for all install/build commands
