A visual design system that organizes a page through containers inside other containers, combining editorial outer shells with inset dark blocks and rounded cards.

In plain words
What is it for?
Use it for agency pages, feature sections, pricing blocks, cards, and call-to-action areas.
Why use it?
It creates hierarchy and rhythm through nested boundaries instead of a flat sequence of unrelated sections.

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

nested-container-clean-agency 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 4d 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.

Nested Container Clean Agency Skill

Use When

  • Create a clean agency design system built from nested containers, with an outer editorial shell, inset dark feature blocks, rounded premium cards, and restrained accent color.

Workflow

Scope

  • Apply this as a full design-system direction across page shell, section framing, cards, pricing blocks, call-to-action areas, and layout rhythm.
  • Use it when the interface should feel clean, premium, and agency-led, with strong container hierarchy instead of flat page sections.
  • This is not generic card-grid SaaS and not only a framing utility. The whole composition should be organized through nested shells and inset feature blocks.

Visual target

  • Start with a centered outer page container that defines the main boundaries of the design with visible vertical rails, corner squares, or light frame lines.
  • Inside that outer shell, place one or more inset containers with contrasting surfaces, especially dark rounded feature zones nested within a light editorial page.
  • Build hierarchy by stacking containers inside containers: outer shell, inner dark section, then smaller rounded cards or content panels inside that section.
  • Keep typography clean, modern, and agency-like, with confident headlines, restrained body copy, and minimal UI noise.
  • Use a soft accent color sparingly for pills, buttons, active dots, subtle gradients, and call-to-action emphasis rather than saturating the full layout.

Implementation guidance

  • Prefer a max-width outer wrapper with consistent side padding, vertical boundary lines, and tiny corner markers to establish the global frame.
  • Use nested rounded containers to create depth: a darker major block inside the page, then lighter or darker cards inset within it depending on contrast needs.
  • Maintain generous whitespace between nested layers so each shell feels intentional and breathable.
  • Use border gradients, low-contrast strokes, and soft shadows to separate layers instead of heavy outlines everywhere.
  • Pricing sections, service groupings, or feature comparisons should feel like modular editorial blocks housed inside a larger premium container.
  • Motion should stay minimal and polished: masked text reveals, calm fade-ins, and light hover transitions are enough.

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.
