chore(gemini): add UA header - #7142
Conversation
📝 WalkthroughWalkthroughGemini client initialization now normalizes ChangesGemini HTTP Options
Suggested reviewers: Merge Risk: 🔵 Low · up to The PR adds a default Gemini User-Agent, but caller-supplied headers can currently produce duplicate User-Agent fields, and shared HTTP options may retain mutations across client initialization attempts. The change is mergeable with explicit owner awareness and follow-up for these bounded risks. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Canonicalize a caller-supplied User-Agent before injecting the default.
When a caller provides headers={"User-Agent": "partner-client"}, this case-sensitive check adds a second user-agent key. google-genai==1.65.0 and httpx==0.28.1 preserve both case-insensitive entries, so the request can contain duplicate User-Agent fields. Remove or rename any case-insensitive User-Agent key to lowercase while preserving its value, then add the default only when no such key exists. Add a regression test.

Adds a User-Agent header. It's recommended and will help us identify any error patterns, especially when we change APIs.
