- We Built Ourselves an AI Coding Workbench β Using GitHub Actions as the Sandbox
Why we passed on a self-hosted K8s sandbox cluster, third-party sandbox services, and off-the-shelf managed agents β and ended up using GitHub Actions runners as the sandbox for our team's AI coding workbench. A record of the design trade-offs: treating GHA's instability as part of the contract, making conversation continuity the only hard guarantee, and using OIDC to keep zero secrets in the sandbox repo. Many technical decisions only become available once you stop trying to do everything.
