frontend-patterns

frontend-patterns is a skill for Claude Code from design-sparx/mantine-analytics-dashboard. It costs 15 tokens per session (102 once invoked), scanned A, original, MIT.

A set of frontend architecture and UI patterns for React and Next.js. It covers how to split components, compose related controls, and keep display code separate from application coordination.

In plain words
What is it for?
Use it when building pages or components, reviewing frontend architecture, or planning features that need composition, container and presentation separation, or compound components.
Why use it?
It helps prevent large, tightly coupled components and makes UI code easier to change. The patterns also keep styles, tests, and types close to the components they belong to.

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

frontend-patterns 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.

What it actually says

Frontend Patterns

Frontend architecture guidance for this project.

When to Use

  • Building new UI components or pages
  • Reviewing frontend architecture
  • Planning feature implementation

Guidelines

  • Prefer composition over inheritance
  • Keep components small and focused
  • Separate container and presentational components
  • Use compound components for related controls
  • Co-locate styles, tests, and types with components
Changes

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.
