Agent infrastructure notes
Patterns worth stealing
from real agent harnesses.
Claude Code, Goose, Open SWE, the internal agents companies describe on their eng blogs — the harnesses that actually ship keep arriving at the same handful of patterns. I read them closely, write up the ones that hold, and show how to build each with Genkit. I'm Jeff Huang — founding team of Genkit, Python SDK lead, years of Firebase serverless before that. This is reading I'd be doing anyway, written down.
