Google Antigravity & Gemini CLI

Google Antigravity (AGY) and the Gemini CLI natively support agent skills located in .agents/skills/ within your workspace, as well as global skills in ~/.gemini/config/skills/. Integrating Dmint provides two key benefits:
  1. Agent Skill: Equips Antigravity with the system knowledge to author and verify Dmint policies.
  2. MCP Security Gateway: Intercepts MCP servers called by Antigravity subagents, guaranteeing that tool actions cannot escape your configured boundaries.

​
1. Install the Skill

Run the skill installer from your workspace root:
This creates .agents/skills/dmint-policy-manager/ directly in your workspace. Antigravity discovers it immediately.

​
2. Using the Skill in Antigravity

Once installed, simply prompt Antigravity in your chat or prompt window:
Antigravity will:
  1. Load the dmint-policy-manager skill instructions.
  2. Draft access.md following least-privilege principles.
  3. Run dmint create-policy to compile policy.json.
  4. Run dmint verify-policy to prove zero validation errors.

​
3. Protecting Antigravity Subagents with dmint-mcp

When running autonomous Antigravity subagents with external MCP tools:
  1. Configure your MCP server in mcp_protection.json.
  2. Launch dmint-mcp as the endpoint for your subagent tools.
  3. Keep dmint dashboard running in a browser tab at http://127.0.0.1:8080 to review and approve sensitive actions as subagents execute.
