Using Gemini 3 Pro + Antigravity: When I used to do Vibe Coding, due to the limitations of context length, I focused heavily on context engineering management. For large-scale projects, my workflow was: - Dependency management: Write PRD -> Review -> Write architecture document -> Review -> Break down tasks based on dependencies. - Detail management: Write detailed, independent development requirement documents for each subtask -> Review for completeness. - Execution management: Open multiple terminals for parallel development -> Code review -> Independent testing of subtasks -> Integration testing -> Final integration. So, my core tasks were: clarifying my requirements, defining each step’s subagent, specifying the output style, and configuring the relevant skills for each subagent. With Gemini 3 Pro’s ultra-long context management and advanced reasoning and planning capabilities, plus Antigravity’s complete replacement of Cursor, once the requirement documents are defined, I can reuse the architecture design Agent and document review Agent to automate development using the plan mode. It’s been 3 years since the AI-driven revolution started, and looking back to when ChatGPT first came out, I made this point: In the AI era, everyone is a product manager. Thoughts on future development: With the rapid advancement of AI and humanoid robots, our labor force will be liberated. Our focus should be: identifying needs, finding inspiration, looking inward, and observing outward. What we need: read more, experience more, feel more. Draw inspiration from life and work, and define value through deep reflection.
