layout-system

layout-system is a skill for Claude Code, Codex from sanky369/vibe-building-skills. It costs 148 tokens per session (1,787 once invoked), scanned A, original, MIT.

A set of instructions for building or fixing responsive web-page layouts, including grids, cards, sidebars, and page structure. It adapts layouts to different screen sizes such as phones and desktops.

In plain words
What is it for?
Use it to create or refactor page shells, grids, component layouts, alignment, responsive behavior, and fixes for overlap or overflow.
Why use it?
It helps resolve pages that break on mobile, have misaligned elements, inconsistent spacing, or poor breakpoint choices. It bases the layout on the content instead of applying a fixed pattern.

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

layout-system 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Layout System

Produce working, mobile-first layout code for the user's actual screens — a refactored page shell, grid, or component layout — not a CSS tutorial. Governing principle: content determines structure. Choose Grid vs Flexbox by the shape of the content, place breakpoints where the content breaks, and let flexible tracks absorb the rest.

When to use / handoffs

  • Use for page structure, alignment, responsiveness, grids, overlap/overflow bugs, and breakpoint strategy.
  • Spacing values themselves inconsistent across the app (no scale) → establish tokens first via skills/frontend-design/design-foundation.
  • Text hard to read at some widths (line length, fluid type) → skills/frontend-design/typography-system.
  • Layout is fine but the screen feels cluttered → skills/frontend-design/visual-hierarchy-refactoring.

Step 1 — Inspect the codebase

  1. Locate the target. If the user named a screen/component, read it plus its CSS. Otherwise glob the main layout files (**/layout.*, **/App.*, **/*page*, global CSS).
  2. Detect the styling system. Tailwind classes vs CSS Modules vs styled-components — deliver in the same system.
  3. Grep for layout smells and record counts:
    • width:\s*\d+px|w-\[\d+px\] — fixed widths (breakage source #1)
    • position:\s*absolute outside overlays/badges — layout by coordinates
    • float:|margin-top:\s*-|margin-left:\s*- — legacy/negative-margin hacks
    • @media — count distinct breakpoint values; >4 distinct min-widths = breakpoint sprawl
    • overflow-x and 100vw — horizontal-scroll suspects
  4. Read existing breakpoints (Tailwind screens, or media queries) — reuse them unless they're the problem.
  5. Check for spacing tokens — if a scale exists, all new gaps/padding must use it.

Step 2 — Intake

Ask in one batch, only if not inferable: which screen/flow matters most, and the smallest and largest viewports that matter (default: 320px–1440px, content capped ~1200–1280px). Infer density and stack from the code. Don't stall — with a named target and visible code, state assumptions and build.

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.
