Envoy on Kittens: Improving Developer and Maintainer Velocity
summary
RepoKitteh is a lightweight GitHub App plus Starlark runtime that replaces bespoke GitHub apps and many Actions by running Starlark scripts on events, pinned to module SHAs and executed serverlessly in GCP. It exposes slash-command handlers, a tracing UI that shows event payloads and call traces, secret handling, and per-PR state storage so owners checks, /backport, /assign, /review, /retest and /wait workflows run deterministically. Envoy runs it for ~2 years; demos show adding labels from a /backport command and enforcing PR-body checks.
