Agent Runtimes & Sandboxing

When developing agents, especially AI- or LLM-based, it's important to consider isolation, performance, and execution location (server vs client). We discussed the following concepts:

• Server-hosted runtimes: Node, Bun, Deno
• Server-side sandbox: Docker, gVisor, MicroVMs
• WebAssembly (WASM): server- or client-side
• WebContainers: full Linux-like environment in the browser
• Serverless/Edge runtimes: Cloudflare Workers, Deno Deploy, Vercel Edge Functions

AGENTS.md — Workflow Cheat Sheet

A practical cheat sheet for designing robust, testable, future-proof agent workflows.

This is optimized for:

• single main agent ownership
• explicit skill usage
• sequential, deterministic execution
• “good enough” optimization

Redirecting Based on Host Name

Let say you want to host example1.com, example2.com, and example3.com on your machine, respectively to localhost:8080, localhost:8181, and localhost:8282.

Note: Since you don't have access to a DNS server, you should add domain name entries to your /etc/hosts (you can't do this on CDF machines):

... 127.0.0.1 example1.com example2.com example3.com ... To proxy eaxmple1.com we can't use the location part of the default server. Instead we need to add another server section with a server_name set to our virtual host (e.g., example1.com, ...), and then a simple location section that tells nginx how to proxy the requests:

Use vagrant and ansible on Windows (WSL2)

Making vagrant and ansible work together with virtualbox as a provider is not well documented across the documentations. Ansible's control node doesn't work on Windows. However, it works on WSL which make the installation of ansible and vagrant on WSL necessary and the access from WSL to virtualbox which is still running under the Windows host.

Requirements

• Windows 10
• Virtualbox
• WSL2

Merging Unity3D scenes

Unity3D scenes and prefabs cannot not be merged automatically by default. Working on one scene / prefab at the same time can cause issues when a merge conflict happens. Usually that means that one version needs to be discarded or the files need to be merged manually (which isn't easy).

However, Unity provides the UnityYAMLMerge tool with each Unity installation to merge scenes and prefabs semantically for manual setup. This is also called Smart Merge. The tool can be accessed from the command line and is also available to third-party version control software like Git, etc. To setup the smart merge for Git, follow the following steps.
