A Basic Go Agent Loop Is 20 Lines; Production Needs Real Architecture
rseroter · x · 2026-08-27
rseroter highlights @danicat83's Part 3 of "Gemini for Go Developers". Core thesis: writing a basic agent loop in Go takes 20 lines of code, but a production agent requires deliberate architecture.
The author built the exact same domain agent across three abstraction tiers — a Retro Game Appraiser that queries personal collection inventory while cross-referencing fair market prices via Google Search grounding — to show where raw API loops end and frameworks become essential:
- Low-level: the Go GenAI SDK, a direct 1:1 mapping to the Gemini wire protocol, with the dispatch loop and conversation managed manually
The linked official Google Gen AI Go SDK docs show support for the Gemini Developer API and Enterprise Agent Platform, covering text-only and multimodal use cases.
