From 1f203a7ac0efad15ec3fc0a4c5b335ad7073a52f Mon Sep 17 00:00:00 2001 From: Claude Sonnet 5 Date: Fri, 3 Jul 2026 22:33:22 +0000 Subject: feat(provider): add native Google Gemini API adapter (Phase 4) Adds internal/provider/google, the second native cloud adapter (following internal/provider/anthropic's pattern) on top of Phase 1's provider-neutral tool-use loop, wired to a Docker-sandboxed NativeRunner under agent.type: "google" -- a separate execution path and budget bucket from the existing CLI-subprocess "gemini" ContainerRunner, which is untouched. Wire-format research (the highest-risk part of this adapter): Gemini's multi-turn function-calling shape was resolved by cross-referencing the REST API reference's own generateContent example against the go-genai SDK's struct tags on GitHub -- both agree on functionCall/functionResponse parts keyed by "name" (with an optional "id" for round-tripping ToolCall.ID), with the response fed back inside a "user"-role Content (Gemini has no tool/function role, mirroring Anthropic's lack of one). A separate fetched source (the function-calling guide page) was deliberately discarded as a reference for this shape -- it documents a different, newer "Interactions API" whose call_id/type:"function_result" structure doesn't fit the contents/parts/candidates shape used everywhere else. - internal/provider/google: request/response translation, systemInstruction handling, role mapping (assistant->model, tool-results->user role), per-model-prefix pricing table (2.5 Pro/Flash/Flash-Lite, 2.0, 1.5 tiers) - internal/retry: IsRateLimitError additively extended for RESOURCE_EXHAUSTED - internal/config: RunnersConfig.Google/GoogleEnabled() - internal/cli/serve.go, run.go: runners["google"] construction mirroring the Anthropic wiring exactly (Docker sandbox default) - docs/api-keys-setup.md: Google marked wired-up, budget-bucket/disable/ verify guidance added matching the Anthropic section go build/vet/test -race all pass. No live Gemini API key available in this environment; verified via fake-httptest-server adapter tests (plain text, tool-use round-trip, multi-turn tool-result, rate-limit error matching) plus a Pool/NativeRunner routing test. Live E2E is a follow-up once a key is configured, same as Phase 2's Anthropic adapter.
