add-layout

add-layout is a command for Claude Code from go4cas/quiver. It costs 0 tokens per session (481 once invoked), scanned A, original, MIT.

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.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { inject } from '../framework/index.js'.

Good fit 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.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 18d 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 bun 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:
bun run typecheck && bun run test && bun 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.
