omarchy-theme-maker is a skill for Claude Code, Codex from asimons81/hermes-field-kit. It costs 49 tokens per session (1,151 once invoked), scanned A, original, Apache-2.0.

A desktop theming tool for Omarchy, a Linux desktop environment, that builds a color palette from a wallpaper or photo and applies it as a theme.

In plain words
What is it for?
Use it to create an Omarchy theme from an image, set the image as the background, and apply the resulting theme.
Why use it?
It avoids choosing desktop colors by hand and checks that important colors have enough contrast for readability. It only works with Omarchy.

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

omarchy-theme-maker 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 today.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/palette_to_theme.py, tests/test_contracts.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

omarchy-theme-maker

Overview

Builds a complete Omarchy user theme from a single image. The bundled script extracts dominant colors via median-cut quantization, decides dark or light mode from saturation-weighted lightness, emits a colors.toml using the canonical Omarchy palette keys calibrated against the stock tokyo-night (dark) and catppuccin-latte (light) ramps, enforces WCAG contrast floors on accent and named colors, and installs the image as the theme background.

The skill never edits stock themes under /usr/share/omarchy/ and never writes outside ~/.config/omarchy/themes/<slug>/. It does not theme non- Omarchy desktops and does not cover general Omarchy configuration.

When to Use

  • "Make an Omarchy theme from this image/wallpaper/photo."
  • "Theme my desktop to match this artwork."
  • "Build a custom Omarchy palette named with this background."

Counter-triggers — do not load this skill when:

  • The target desktop is not Omarchy (generic Hyprland, GNOME, KDE theming).
  • The user wants to tweak a stock theme's colors by hand rather than derive from an image.
  • The task is general Omarchy configuration (bars, keybindings, monitors); that belongs to a general Omarchy skill, not this one.

Workflow

  1. Verify prerequisites: omarchy version succeeds and python3 -c "import PIL" succeeds (Pillow is the only dependency).
  2. Locate the source image locally. If given a URL, download it to a temporary directory first.
  3. Dry-run the generator with --print and read the emitted palette: python3 <skill-root>/scripts/palette_to_theme.py IMAGE --name "Name" --print.
  4. Check the reported mode and contrast lines. If the image is busy or mixed-brightness and auto mode picked wrong, rerun with --mode dark or --mode light.
  5. Write the theme for real (same command without --print). Confirm the script created ~/.config/omarchy/themes/<slug>/colors.toml and backgrounds/<image> and refused to clobber an existing colors.toml unless --force was passed.
  6. Offer the user the palette for review; apply only when the user asks: omarchy theme set <slug>.
  7. Verify: omarchy theme current prints the new theme name and the active background symlink points at the staged image.

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.
