it depends where you want your agent to live. inside the sandbox, start a sandbox via the CLI and run your agents/do your dev in there. outside the sandbox, you'd configure your harness to use the MCP / skill integration. here's the guide: https://docs.microsandbox.dev/getting-started/agents

if you're building a harness, the SDK provides better integration. let me know if you hit any blockers.

for sync, it's currently in the works.
