Antigravity (Google's IDE sandbox product, different from Gemini CLI) is
removed from:
src/onboarding.ts — drop from LLM_PROVIDER_IDS + OAuth-flow picker
src/pi-migration.ts — drop from LLM_PROVIDER_IDS migration list
src/web/onboarding-service.ts — drop from web-UI provider list
src/tests/integration/web-onboarding-contract.test.ts — update contract
src/resources/extensions/sf/doctor-providers.ts — drop from CLI_AUTH_PROVIDERS
src/resources/extensions/sf/key-manager.ts — drop UI listing
src/resources/extensions/sf-usage-bar/index.ts — delete entire quota fetcher block (~200 lines)
packages/pi-coding-agent/src/cli/args.ts — drop PI_AI_ANTIGRAVITY_VERSION doc
packages/pi-coding-agent/src/utils/proxy-server.ts — drop from claude provider chain
Reason: antigravity has no vendor-published core library we can embed
(unlike @google/gemini-cli-core for the Gemini CLI). Continuing to
hand-roll OAuth against daily-cloudcode-pa.sandbox.googleapis.com is
exactly the pattern Google has started banning for third-party tools.
Removing the code removes the ban risk.
pi-ai provider code, OAuth util, and models.generated entries for
google-antigravity are removed in follow-up commits (separated for
reviewability — each layer verified independently).
Build passes. Note: this is a breaking change for any user who had
google-antigravity configured — they'll need to migrate to
google-gemini-cli (OAuth), google (API key), or google-vertex.
