This guide shows you how to set up Antigravity for spec-driven development.

The dedicated Antigravity plugin packages the shared SpecDD skills for Antigravity’s plugin system. In the SpecDD tools reference, this is the documented Antigravity install path.

Prerequisites

Before you start, make sure you have:

Steps

1. Initialize SpecDD

From the selected content root:

specdd init

Confirm that the project contains:

AGENTS.md
.specdd/
  bootstrap.md
  bootstrap.project.md

2. Install the Antigravity plugin

Source and install details: github.com/specdd/plugin-antigravity

Install the SpecDD plugin from its plugin repository:

agy plugin install https://github.com/specdd/plugin-antigravity.git

This installs the SpecDD skills generated for Antigravity from the shared SpecDD agent plugin source.

3. Open the project root

Open or start Antigravity in the folder that contains the bootstrap files and root .sdd file.

SpecDD is local and path-based, so starting from the correct root makes spec resolution and path references more reliable.

4. Verify the plugin

Use:

Orient in this SpecDD project.

Then ask about a real spec:

Explain the Itinerary spec.

The response should mention SpecDD context, local constraints, and authority.

5. Use spec-focused prompts

After setup, use short prompts:

Plan the Itinerary validation change.

Implement the open validation task.

The plugin handles the SpecDD workflow. The prompt should identify the work.
