Sandcastle 0.6.1 adds structured output, Cursor, Copilot support

ANNOUNCEMENTPRODUCTGITHUBX

Matt Pocock's Sandcastle orchestration library hits version 0.6.1, bringing structured object output to AI coding agents. The update also adds execution support for the Cursor and GitHub Copilot CLIs within its isolated sandboxes.

// ANALYSIS

Extracting validated data from autonomous coding agents transforms Sandcastle from a simple sandboxing wrapper into a programmable AI infrastructure primitive.

  • –`Output.object` lets developers extract typed, validated data (via Zod or Valibot) directly from agent stdout
  • –Native support for Cursor and GitHub Copilot CLIs expands the ecosystem of compatible coding assistants beyond Claude Code
  • –Running these tools inside isolated Docker or microVM boundaries prevents destructive code changes to host environments
