Google I/O 2026 Eve: Three Sessions on Goal-Based Agentic Coding — Tell the Agent 'Raise Test Coverage to 80%' Instead of What to Change

Google I/O 2026 (May 19-20) devotes three sessions to agentic coding workflows positioning Gemini as Google's answer to Claude Code and Cursor. The key architectural difference: goal-based rather than instruction-based — developers specify outcomes like 'raise test coverage to 80%' or 'reduce p95 latency' and the agent identifies needed changes. Gemini 4 is expected with up to 10M token context, potentially fitting 1M+ line codebases in a single API call.
