## Description

Frontend Design is an official Anthropic plugin for Claude Code that bundles design-system patterns, component recipes, and a frontend-design skill that the Claude Code agent follows when asked to build web components, pages, or applications. The plugin's intent is to push the agent away from generic AI-generated UI aesthetics and toward distinctive, production-grade interfaces by codifying repeatable visual and structural decisions.

When invoked, the skill reads files in the active project to understand the existing component conventions, writes new components and styles into the project, and follows a structured set of design decisions captured in its reference material. It does not request shell execution, network access, or credentials of its own.

Frontend Design is one of the few entries in the catalog with the official trust level — published by Anthropic, the maintainer of Claude Code itself, which means the most favorable trust adjustment available in the scoring model. The remaining risk signals come from filesystem read and write, which are the minimum required for any plugin that produces source files, and do not match any dangerous combination. It is one of the lowest-risk plugins in the catalog.

## Why it scored 20

The score starts at the catalog's neutral base of 50 and moves only through the signals below. The formula is published at https://catalog.anomity.ai/about — there is no model and no hidden heuristic.

| Signal | Contribution | Severity | Evidence |
| --- | --- | --- | --- |
| Published by the vendor | -40 | trust offset |  |
| 1 high-risk capability: filesystem:write | +10 | high |  |

Clamped result: **20/100**, band **low**.

## Capabilities

| Capability | Name | Security implication |
| --- | --- | --- |
| `filesystem:read` | Filesystem read | Can read files on the host system. Used for context, indexing, or analysis. |
| `filesystem:write` | Filesystem write | Can create, edit, or delete files on the host system. High-impact capability — anything from helpful edits to planting persistence. |
