add-layout

A command for creating a new page layout in the Quiver app. A layout is the shared outer structure around a page, such as a menu, sidebar, or full-width frame.

In plain words
What is it for?
Use it when adding layouts such as sidebars, blank screens, or full-width pages. It creates the layout file and registers its name for use by pages.
Why use it?
It removes the repetitive setup needed to create and register a layout while keeping it consistent with the app's existing style and data rules.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-layout scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Create a new Quiver layout named: $ARGUMENTS

The argument is a layout name in any case (e.g. sidebar, BlankLayout, full-width). Normalise to PascalCase with a Layout suffix — <Name> below means this full suffixed name (e.g. SidebarLayout). The registration key is the lowercase base name without the suffix (e.g. sidebar).

Follow these steps exactly:

  1. Create src/layouts/<Name>.js:
import { html } from '@arrow-js/core'

export function <Name>(content) {
  return html`
    <div class="min-h-screen">
      ${content}
    </div>
  `
}
  • The layout receives the rendered page as its content argument — render it as ${content} (no () => needed; content is already an Arrow template, not a reactive value)
  • Use Tailwind CSS utility classes; match the visual style of existing layouts in src/layouts/
  • If the layout needs global DI data (e.g. app name, current user), inject it using inject from ../framework/index.js:
    import { inject } from '../framework/index.js'
    const app = inject('app', { name: 'Quiver', tagline: '' })
    
  • Apply Arrow.js rules: wrap reactive values in () =>, no <!-- --> HTML comments inside template literals
  • Annotate the exported layout function with JSDoc @param/@returns — strict checkJs is enforced and untyped params fail npm run typecheck
  1. Register in src/layouts/index.js:
import { <Name> } from './<Name>.js'
// add to the layouts object:
<key>: <Name>,
  1. Verify — run and fix any failures:
npm run typecheck && npm test && npm run test:e2e
  1. Report:
    • The file created
    • The key to use in meta.layout (e.g. export const meta = { layout: '<key>' })
    • Any DI keys the layout reads and where to provide() them in src/main.js

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
