Introducing Sandcastle – Master.dev Blog

Sandcastle is a low-level TypeScript primitive for orchestrating multiple AI coding agents in parallel using git worktrees and optional Docker sandboxing, avoiding the file-conflict problems of running several agents in the same working directory. The post walks through installing the npm package, configuring Claude Code and GitHub tokens, running a simple hello-world prompt, and then building a custom script that pulls unblocked GitHub issues via the gh CLI, lets a user pick which ones to implement, and fires off parallel Claude Code agents that each work in their own branch and open a pull request.
