Build software at the speed of thought. This kit adapts Spec-Driven Development for Google Antigravity, leveraging the native .agent workflow engine.
- Clone this repo into your workspace.
- Antigravity will automatically detect the
.agent/workflowsdirectory. - Start Vibe Coding:
| Workflow | Phase | Description |
|---|---|---|
/define |
Spec | Drag in screenshots/sketches. Gemini 3 creates a rigorous spec. |
/architect |
Plan | Generates technical plans & parallel task graphs for Manager View. |
/execute |
Build | Spins up independent agents to build Frontend & Backend in parallel. |
/verify |
QA | Visual regression & logic testing using the integrated Chrome browser. |
/refactor |
Cleanup | Audits and refactors legacy code per constitution before adding features. |
- Artifacts over Logs: We don't read chat logs. We review generated Artifacts (Specs, Plans, Checklists).
- Vision First: Specs shouldn't just be text. Use Antigravity's vision to "see" the design.
- Manager Mode: Don't serial-code. Use
/executeto run multiple agents at once.
-
Copy the kit's core folders into your project root:
cp -r /path/to/spec-kit-antigravity/.agent . cp -r /path/to/spec-kit-antigravity/memory . cp -r /path/to/spec-kit-antigravity/templates .
-
Calibrate the Constitution (
memory/constitution.md) to reflect your project's tech stack, style guide, and forbidden patterns. -
Bootstrap a baseline spec (Reverse Spec):
- Open the Antigravity chat (Manager View).
- Run:
/define Create a baseline spec for the existing authentication module in src/auth.
-
Add new features using the usual flow:
/define …→/architect→/execute→/verify.
-
(Optional) Run the Refactor workflow on legacy modules before adding features:
/refactor src/legacy_module
