Google Ads API Developer Assistant v4.0.0 Overhauls Tool with Unified Plugin Architecture and AI Agent Support

Google released version 4.0.0 of its Ads API Developer Assistant, restructuring it as a globally available plugin that integrates Google Ads–specific capabilities into AI coding environments. The update adds support for Antigravity and Claude Code while enabling developers to generate code across Python, Java, PHP, .NET and Ruby; validate Google Ads Query Language syntax before execution; retrieve ad performance data via natural language; diagnose API errors conversationally; and inspect Protobuf schemas on demand. Performance improvements reduce token consumption and resource overhead by loading only task-specific rules and schemas rather than supplying everything upfront.
