Google Ads API Developer Assistant v3.0.0 Released
Google announced v3.0.0 of the Google Ads API Developer Assistant on 2026-06-10. The release migrates the Assistant from gemini-cli to the Antigravity agent framework and converts its monolithic context into a modular, skills-based architecture to improve reliability, reduce token usage, and lower hallucinations. New and moved skills include validate_gaql, troubleshoot_conversions, explain, step_by_step, get_cids_under_mcc, inspect_object, and pmax_listing_filter. The update enforces explicit api_version arguments for critical skills, adds stricter GAQL validation rules (including a ban on SQL aggregate functions in GAQL), and introduces developer experience improvements such as a persistent .venv, a 19-hour API version cache, and persistent logs. Support for gemini-cli will terminate on 2026-06-18. The post is authored by Bob Hancock of the Google Ads API Team.
A technical release from Google for a developer tool used with Google Ads API affects developers' workflows, enforces migration away from gemini-cli, and introduces architecture and validation changes that improve reliability and require action by integrators.
