Orchestrate, Don't Code: 6 Essential Best Practices for Google Antigravity

 

1. Adopt the Spec-Driven Development (SDD) Workflow

In the Antigravity era, "vibe coding" (writing vague prompts and hoping for the best) is the fastest way to accrue technical debt. The gold standard for 2026 is Spec-Driven Development.

 

Before spawning an agent, ensure you have a "Source of Truth" document. Antigravity works best when it has a clear SPEC.md or PLAN.md to follow.

  • The Best Practice: Always start in Planning Mode. This forces the agent to generate an Implementation Plan and a Task List before it touches a single line of code.

  • Why it works: It allows you to catch architectural errors early. If the agent suggests using Flask but your stack is FastAPI, you can correct the plan before the code is generated.

2. Master "Mission Control": Parallel Agent Management

One of Antigravity's "superpowers" is the Manager Surface. Instead of one AI helping you, you can deploy a team of specialized agents.

The "Pod" Strategy

For complex features, deploy three distinct agent archetypes:

  1. The Design Lead: Focuses strictly on UI/UX, Tailwind, and CSS.

  2. The Builder: Handles backend logic, API routes, and database schemas.

  3. The QA Specialist: Constantly runs the integrated browser and terminal to verify that the other two haven't broken the build.

Pro-Tip: Use the Agent Side Panel to monitor their "Artifacts" (screenshots, recordings, and diffs) asynchronously. You don't need to watch them work; just review the deliverables.

3. Leverage "Skills" for Proprietary Context

Standard AI often struggles with internal company libraries. In 2026, the best Antigravity setups use Skills—TypeScript definitions that give agents permission to run local scripts or query internal databases.

  • Create a "Librarian" Skill: Map your internal component library (e.g., your custom Storybook) so the agent doesn't hallucinate generic Tailwind classes.

  • Create an "Ops" Skill: Give the agent a check_staging_health() tool. Before a merge, the agent can autonomously check Sentry or Datadog to ensure the environment is "green."

4. Asynchronous Feedback via Artifacts

Antigravity introduces a "Google Docs" style of coding. When an agent generates a plan or a walkthrough, don't just "Accept" or "Reject."

  • Best Practice: Leave comments directly on the Artifacts.

  • If an agent shows a screenshot of a new dashboard and the alignment is off, highlight the area and leave a comment. The agent will read that feedback and fold it into the next iteration without you needing to re-prompt the entire task.

5. Security and "Prompt Injection" Hygiene

With great autonomy comes great risk. Because Antigravity agents can browse the web and execute terminal commands, they are susceptible to "indirect prompt injection."

Warning: Be cautious when asking an agent to "summarize this documentation" from an untrusted URL. Malicious actors can hide instructions in CSS or comments that tell the agent to exfiltrate your .env files.

  • The Guardrail: Never leave your API keys in plain text. Use Antigravity's built-in secret management and restrict agent permissions to specific directories using Workspace Rules.

6. Optimization for GEO (Generative Engine Optimization)

If you are building public-facing software or documentation, you must optimize for how AI models (like Gemini 3) "read" your code and content. This is known as Generative Engine Optimization.

  • Structured Hierarchy: Use clear H1-H3 headers in your README.md and documentation.

  • Schema Markup: Use Antigravity to automatically generate JSON-LD schema for your web apps. This helps AI search engines understand the "intent" of your software, making it more likely to be cited in AI Overviews.


Conclusion: The Future is Orchestration

Using Antigravity effectively means shifting your mindset from writing to reviewing. By focusing on high-level specifications and managing specialized agents, you can build production-ready applications at a speed that was impossible just two years ago.
