Skill of the day: `theme-factory`

theme-factory is an official Anthropic Agent Skill shipped inside the example-skills plugin (marketplace anthropic-agent-skills). It styles artifacts with one of 10 preset color/font themes, or a custom theme you review first. Install: /plugin install example-skills@anthropic-agent-skills. It is not Anthropic brand colors (brand-guidelines). MDX pillar: reviews (never skills). No Labs volume on 2026-10-04. Checked 2026-10-04.

TL;DR: Show theme-showcase.pdf, wait for an explicit choice, then apply — or draft a custom theme and show it before applying. [GAP]: no solo /plugin install theme-factory@… — install unit is example-skills. Labs [GAP] — do not borrow webapp-testing 10 or brand-guidelines 140.

What it does

SKILL.md frontmatter (fetched 2026-10-04):

• name: theme-factory
• description (paraphrased): Toolkit for styling artifacts with a theme — slides, docs, reports, HTML landing pages, and similar. Ten preset themes with colors/fonts, or a new theme generated on the fly.
• license: Complete terms in LICENSE.txt → Apache-2.0, Copyright 2026 Anthropic, PBC. (LICENSE.txt)

Usage (skill body): show theme-showcase.pdf unchanged → ask which theme → wait for an explicit choice → apply colors and fonts. Do not silently restyle.

10 themes (names + identities from SKILL.md only — [GAP] hex codes and font pairs live in themes/ and were not fetched):

1. Ocean Depths — professional, calming maritime

2. Sunset Boulevard — warm, vibrant sunset

3. Forest Canopy — natural, grounded earth tones

4. Modern Minimalist — clean contemporary grayscale

5. Golden Hour — rich, warm autumnal

6. Arctic Frost — cool, crisp winter

7. Desert Rose — soft, sophisticated dusty tones

8. Tech Innovation — bold, modern tech

9. Botanical Garden — fresh, organic garden

10. Midnight Galaxy — dramatic, cosmic deep tones

Custom theme: if none fit, generate a named theme from the user's description, show it for review, then apply.

Labs: no item for theme-factory / claude theme factory on 2026-10-04 — [GAP]. Do not invent vol/KD.

Install (Claude Code)

/plugin marketplace add anthropics/skills

Then Browse → anthropic-agent-skills → example-skills → Install, or direct:

/plugin install example-skills@anthropic-agent-skills

Fact (marketplace.json, 2026-10-04): marketplace name anthropic-agent-skills; plugin example-skills; skill path ./skills/theme-factory. Installing pulls the whole example set (siblings include algorithmic-art, brand-guidelines, canvas-design, web-artifacts-builder, mcp-builder, and others).

[GAP]: marketplace has no standalone theme-factory plugin — do not invent /plugin install theme-factory@….

Walkthrough: add the marketplace.

When to use / when not

Use when you want a coherent preset theme (or a reviewed custom theme) on an artifact, and you want the PDF showcase before a choice rather than a guessed palette.

Do not:

• Anthropic official brand colors/typography → live brand-guidelines radar — do not re-Intake
• Generative / algorithmic art → live algorithmic-art radar — do not re-Intake
• Static poster/PDF canvas as the job → live canvas-design radar — do not re-Intake
• React multi-component artifacts → live web-artifacts-builder radar — do not re-Intake
• MCP servers → live mcp-builder radar — do not re-Intake
• Re-Intake skill-creator / frontend-design / internal-comms (covered elsewhere — no 404 hrefs)

Limits + live pairings

• Example skill; product behavior can differ from the markdown.
• Ships with the full example-skills bundle — expect siblings, not a minimal single-skill package.
• Hex / font pairs in themes/ — [GAP] unless you fetch those files yourself before citing any.
• No Labs volume today.
