theme-factory

An agent skill by anthropics, from anthropics/skills. Tags: anthropic, design, documents, office, slides, visual-art.

What it does

Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add anthropics/skills --skill theme-factory

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/anthropics/skills
cp -r skills/skills/theme-factory ~/.claude/skills/theme-factory

Safety box score

Grade A, minimal risk: 4 of 100 risk points, rated 2026-10-15. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This skill is a styling-only theme kit for artifacts like slides and docs. It does not ship executable code or networked tooling, so the main residual risk is low opacity from the unreadable `theme-showcase.pdf` binary rather than machine or account impact.

Category levels, from 0 (none) to 3 (high)
Category	Level	Why
Code & shell execution	0 (none)	No scripts, shell commands, or code-evaluation steps are included; the skill only describes reading theme files and applying styles.
Network access	0 (none)	There are no URLs, downloads, uploads, or remote API calls in the skill files.
Filesystem reach	0 (none)	The instructions only mention the theme files in `themes/` and viewing `theme-showcase.pdf`; nothing is said about writing outside the working artifact.
Secrets & credentials	0 (none)	The skill does not request tokens, passwords, `.env` files, browser sessions, or other credentials.
Privilege & persistence	0 (none)	No sudo, global installs, services, shell startup edits, or OS-level changes are described.
Instruction hijack surface	0 (none)	There is no instruction to ignore policies, skip confirmations, or follow untrusted remote content; the text is limited to workflow guidance.
Irreversible actions	0 (none)	The skill only applies a chosen theme after user selection; it does not send messages, deploy, publish, or delete anything.
Transparency	1 (low)	`theme-showcase.pdf` is a binary file that could not be read in this review, so one shipped artifact is opaque.

Before installing

Open `theme-showcase.pdf` locally and confirm it only contains the expected theme previews.
Verify there are no hidden scripts or external links in any downstream theme-rendering tool your agent uses with this skill.
If you rely on custom themes, test one in a scratch artifact first to confirm the skill only changes styling.
