artifacts.

Publish a self-contained HTML page to a shareable, unguessable link.

Set up with an agent

Paste this to Claude Code, Codex, Cursor, or any coding agent — it installs everything and walks you through sign-in.

Set up the Mostly Serious "artifacts" tool so you can publish HTML artifacts for me. Install the "artifacts" agent skill from github.com/mostlyserious/artifacts using whatever method you prefer for installing agent skills. Install the CLI: `curl -fsSL https://artifacts.mostlyserious.dev/install | bash`. Then authorize it: ask me for my @mostlyserious.io email, run `artifact login <email>` for me, tell me to click the confirmation link in my email, and wait for it to finish. From now on, when I ask for an HTML artifact, write a self-contained HTML file and run `artifact upload` to give me a shareable URL.

Or install manually

Prefer to run it yourself? Paste this into a terminal.

# 1. Install the agent skill (adds it to your coding agent)
npx skills add mostlyserious/artifacts --skill artifacts

# 2. Install the CLI
curl -fsSL https://artifacts.mostlyserious.dev/install | bash

# 3. Authorize (sends an email verification link)
artifact login you@mostlyserious.io
