# Arch Portal

> A scroll-pinned hero that walks the visitor through one building, door by door, toward the light. Each wall is a real slab with its own opening: a round-arched gate in a stone surround, a low segmental arch, a full-circle round door and a tall last arch. One low light sits beyond the last door, and its shadows are traced through every opening, so a runner of light crosses the floors and spills out of the gate under the headline. The headline is drawn in the scene and warms where light passes behind each letter. The last arch is cut to the headline's measured box at every screen size, so the story ends with the words standing in the doorway. Two buildings ship: limewash in afternoon sun, or brick vaults over still water at dusk.

## What you need

- Node.js 18 or newer. Nothing to install.
- Chrome, Chromium or Edge, for the checks and the recording (set `CHROME_PATH` if it isn't found).
- ffmpeg, for the video (or set `FFMPEG_PATH`).
- Internet access when the page is opened, for the fonts (pinned with integrity hashes).

## Install

```bash
curl -fsSL https://lookbk.dev/cli.js | node - add arch-portal-hero
```

The first run prints a sign-in link; open it, approve, and run the command again. Pro skills install for accounts that bought them or have Pro.

Where it installs:

- Run by Claude Code: `~/.claude/skills/arch-portal-hero` only, the one folder Claude Code reads.
- From your own terminal: `~/.agents/skills/arch-portal-hero`, which Codex, Gemini CLI, Copilot CLI, Cursor and OpenCode read, and also `~/.claude/skills/arch-portal-hero` when `~/.claude` exists.

Add `--claude` or `--shared` to write only one of those folders, or `--project` to install into the current folder instead. Start a new agent session afterwards so it picks up the skill.
