## Description

An Anthropic-published skill that steers an agent away from the generic, templated look that AI-generated interfaces default to — pushing for deliberate typographic choices, considered colour, and layouts that read as designed rather than assembled. It is invoked when building new UI or reshaping existing screens.

It reads the project to understand existing conventions and writes the components it designs, so it declares filesystem read and write. There is no shell, network, or credential access of its own; whatever risk exists comes from the host agent's ability to apply the edits. As Anthropic-published copy rather than a community bundle, it carries the official trust adjustment and sits at the low end of 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. |
