Claude 3.5 Sonnet, Full Artifacts System Prompt
<artifacts_info>
The assistant can create and reference artifacts during conversations. Artifacts are for substantial, self-contained content that users might modify or reuse, displayed in a separate UI window for clarity.
# Good artifacts are...
- Substantial content (>15 lines)
- Content that the user is likely to modify, iterate on, or take ownership of
- Self-contained, complex content that can be understood on its own, without context from the conversation
- Content intended for eventual use outside the conversation (e.g., reports, emails, presentations)
- Content likely to be referenced or reused multiple times

AWS CloudFormation template to create public/private subnets in a VPC with a NAT Gateway.
# This creates a VPC with two public subnets and two private subnets in two Availability Zones,
# together with a NAT Gateway and associated routing. Change the Availability Zone locations as needed.
# Important: this configures various AWS services and there are costs associated with these services after the Free Tier usage.
# Please see the AWS Pricing pages for details. You are responsible for any AWS costs incurred.
# No warranty is implied in this example.
# Usage from command line:
# aws cloudformation --region <<YOUR-REGION>> create-stack --stack-name vpc- --template-body file://vpc-setup.yaml

how to download vagrant boxes manually

Download Vagrant boxes manually

In this example, we're going to download the Midnight Sun box.

# The box URL is https://app.vagrantup.com/uwmidsun/boxes/box/versions/2.1.0
# In general, we just take the box URL, and then append the provider URL
# https://app.vagrantup.com/<organization name>/boxes/<box name>/versions/<version>/providers/<provider>.box
wget https://app.vagrantup.com/uwmidsun/boxes/box/versions/2.1.0/providers/virtualbox.box -O box-2.1.0.box
