Add antigravity config alias for Gemini API proxy targets by Copilot · Pull Request #3820 · github/gh-aw-firewall

Copilot · 2026-05-26T00:03:50Z

This change adds antigravity config support to the AWF config surface so users can configure Antigravity without having to reason about legacy Gemini naming. The new config shape resolves to the existing Gemini runtime wiring, keeping behavior unchanged outside config naming.

Config alias
- Accept apiProxy.targets.antigravity in AWF config files
- Map antigravity.host / antigravity.basePath onto the existing Gemini target/base-path runtime fields
- Prefer antigravity when both antigravity and gemini are present in config
Schema + spec
- Extend the published config schemas to include apiProxy.targets.antigravity
- Document the alias in the config spec so editor/schema-driven autocomplete and validation stay aligned
Regression coverage
- Add validation coverage for apiProxy.targets.antigravity
- Add mapping coverage to confirm the alias resolves to the existing Gemini runtime options

Example:

apiProxy:
  targets:
    antigravity:
      host: gateway.google.com
      basePath: /v1alpha

This is treated the same as the existing Gemini target config at runtime.

Pull request overview

This PR adds an apiProxy.targets.antigravity configuration alias intended to let users configure the Gemini API proxy target using the newer “Antigravity” name, while keeping runtime wiring mapped to the existing Gemini options.

Changes:

Add apiProxy.targets.antigravity to the config surface and map it onto the existing geminiApiTarget / geminiApiBasePath runtime options (preferring antigravity over gemini when both are present).
Extend the published JSON schemas to include the new antigravity target.
Add regression tests for validation acceptance and mapping behavior.
