redesign-existing-projects

redesign-existing-projects is a skill for Claude Code from ne11nn/cantos-plugin. It costs 45 tokens per session (873 once invoked), scanned A, original, MIT.

A workflow for improving an existing website or app’s visual design while keeping its current technology and functionality. It checks typography, layouts, missing interface states, and other design choices before applying targeted changes.

In plain words
What is it for?
Use it to review an existing project, identify design problems, and upgrade its CSS, typography, components, layouts, and interface states.
Why use it?
It helps find generic-looking or incomplete parts of an interface without requiring a full rewrite. The audit gives a structured way to identify what needs improvement.

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

redesign-existing-projects 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 7d 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.

Redesign Skill

How This Works

When applied to an existing project, follow this sequence:

  1. Scan — Read the codebase. Identify the framework, styling method (Tailwind, vanilla CSS, styled-components, etc.), and current design patterns.
  2. Diagnose — Run through the audit below. List every generic pattern, weak point, and missing state you find.
  3. Fix — Apply targeted upgrades working with the existing stack. Do not rewrite from scratch. Improve what's there.

Design Audit

Diagnose by running every rule in references/ui-anti-slop.md (§1 Typography → §9 Strategic Omissions) as a checklist against the existing code. For each rule, record whether the current build violates it. The reference is the full audit superset — every generic-AI-pattern, weak-point, and missing-state check formerly listed here lives there now, so new builds and polish passes get the same comprehensive list. List every violation found before moving to Fix.

Upgrade Techniques

When upgrading a project, pull from these high-impact techniques to replace generic patterns:

Typography Upgrades

  • Variable font animation. Interpolate weight or width on scroll or hover for text that feels alive.
  • Outlined-to-fill transitions. Text starts as a stroke outline and fills with color on scroll entry or interaction.
  • Text mask reveals. Large typography acting as a window to video or animated imagery behind it.

Layout Upgrades

  • Broken grid / asymmetry. Elements that deliberately ignore column structure — overlapping, bleeding off-screen, or offset with calculated randomness.
  • Whitespace maximization. Aggressive use of negative space to force focus on a single element.
  • Parallax card stacks. Sections that stick and physically stack over each other during scroll.
  • Split-screen scroll. Two halves of the screen sliding in opposite directions.

Motion Upgrades

  • Smooth scroll with inertia. Decouple scrolling from browser defaults for a heavier, cinematic feel.
  • Staggered entry. Elements cascade in with slight delays, combining Y-axis translation with opacity fade. Never mount everything at once.
  • Spring physics. Replace linear easing with spring-based motion for a natural, weighty feel on all interactive elements.
  • Scroll-driven reveals. Content entering through expanding masks, wipes, or draw-on SVG paths tied to scroll progress.

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.
