fix: Antigravity User-Agent version outdated (1.11.5 → 1.15.8) #1068
Description
Problem
Google has started rejecting requests with older Antigravity client versions, causing this error:
"This version of Antigravity is no longer supported. Please update to receive the latest features!"
This affects all users of the google-antigravity provider when making requests to cloudcode-pa.googleapis.com.
Root Cause
The User-Agent header in packages/ai/src/providers/google-gemini-cli.ts is set to antigravity/1.11.5, but Google now requires a newer version (current latest is 1.15.8).
Proposed Fix
Update the User-Agent from antigravity/1.11.5 darwin/arm64 to antigravity/1.15.8 darwin/arm64 in:
packages/ai/src/providers/google-gemini-cli.ts(line 76)packages/coding-agent/examples/extensions/antigravity-image-gen.ts(line 53)
