I asked top builders and leaders for the prompts they love to use the most. Here's 9 that they've shared with me plus one of my own... cloud.google.com/blog/topics… What's your one indispensable prompt? 👇

Not sure which of the @antigravity surfaces is best for your agentic development workflow? @lukeschlangen and @alexastrum guide you through it.
Replying to @antigravity
@antigravity has four different surfaces. Which one should you use? We wrote a blog post to help you figure it out. cloud.google.com/blog/topics…

Engineering teams frequently inherit monolithic codebases that are not well documented and riddled with tech debt. In this codelab, I provide step-by-step instructions to build a highly structured, open-source multi-agent orchestration framework. By using low freedom guardrails, you can perform a reliable greenfield migration complete with @antigravity browser subagent verification. You'll learn to: 🔹 Separate deterministic and heuristic tasks 🔹 Implement advanced agent design patterns 🔹 Set up closed-loop, self-healing TDD pipelines

Codelab: codelabs.developers.google.c… Automating legacy modernization at scale using agentic pipelines and Antigravity

Building autonomous agents usually means wrestling with context window bloat. Google's new @antigravity SDK solves this by letting a main agent delegate heavy lifting to isolated subagents, keeping the core loop clean. Excellent look at the future of agent orchestration and runtime safety by @kweinmeister. What will you build with the SDK?
The Google @antigravity SDK enables you to embed Antigravity agent capabilities directly into your codebase. My latest article walks through how to get started, then explains each architectural concept in the SDK. linkedin.com/pulse/google-an…

In the latest Agent Factory episode, Google's @rodydavis shows @shirmeir86 how he uses Google @antigravity to orchestrate parallel sub-agents and eliminate developer toil. It's an episode you'll be glad you watched.
Just stopped by The Agent Factory to talk all things Google Antigravity 2.0! 🚀 We dove deep into using skills, multi-agent parallelism, and why I’m leaning into flat architectures. @antigravity @googlecloud @GoogleCloudTech #AgentFactory youtube.com/watch?v=Dk4MD6TN…

Can a hand-drawn sketch become a working @Android app in under 3 minutes with @antigravity ? ✔️Challenge accepted! #NapkinChallenge #Gemini35 #BuildInPublic I challenge: @NoheDev @jocarrasqueira @jason_mayes
Can a hand-drawn napkin sketch become a working app in under 3 minutes? ✔️Challenge accepted! I built a low-tech MIDI sequencer for kids tapping boxes looping beats infinitely in a colorful visualizer. 🎹🥁🎶 Watch me take a sketch and build it using @antigravity 2.0 @Gemini 3.5 Flash (Medium) in under 2 minutes! Video below 👇 I challenge: @geekyouup @rodydavis @ChrisDemeke #NapkinChallenge #Gemini35 #BuildInPublic

Google Antigravity is a Mission Control. 🛰️ In a traditional legacy migration, you’d spend weeks documenting business logic, data models and side-effects. Using my `/orchestrating-greenfield-migration` skill, the process is transformed into a 5-phase autonomous workflow that leverages multiple specialized AI agents: 1️⃣ Audit: Reverse-engineers Express logic 2️⃣ Test Gen: Writes strict functional tests that fail 3️⃣ Scaffold: Builds Next.js project to pass tests 4️⃣ UI Gen: Translates patterns to ShadCN/Tailwind 5️⃣ Verify: Visual "Proof of Work" via automated browser recordings This is efficiency through multi-agent orchestration.

The industry is pivoting from "prompt writing" toward "behavior choreography." Google @antigravity is an incredible agentic development environment for creating, managing and orchestrating autonomous agents.

Stop trying to "prompt" your way through a migration. Dumping a legacy Express app into an LLM just yields hallucinations and wasted context windows. The fix? Multi-agent orchestration. I mapped out how to orchestrate Google @Antigravity planner agent and code-level Agent Skills to safely migrate a legacy Express app to Next.js without breaking business logic. Here is a partial glimpse of the orchestrator skill…

Another interesting @antigravity experiment and this time with @SwiftLang ✨🚀 Created two finder extensions to take advantage of the built in tags! 1. Check all git projects on the system and add tags based on status 2. Check all files and folders and tag based on time buckets

Now you can put a small “drafter” model in front of @googlegemma 4. Multi-Token Prediction, AKA speculative decoding, is here. This configuration guarantees the same quality at up to 3x the speed! Find out more in @MaartenGr’s post.
