Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add BitYoungjae/marketplace --skill omarchy-theming

git clone --depth 1 https://github.com/BitYoungjae/marketplace

Made for: Claude Code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.01689
Opus 5	$0.00027	$0.00844
Sonnet 5	$0.00011	$0.00338
Haiku 4.5	$0.00005	$0.00169

Measured 11d ago against content hash 342220f4a9d4, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade B, and why

omarchy-theming scanned grade B with 1 finding 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 11d ago.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Omarchy Theme Creation

Create themes for Omarchy by defining colors in colors.toml. Colors automatically propagate to all desktop applications.

Quick Start

Create colors.toml with all 22 required variables (see schema below)
Add wallpaper images to backgrounds/
Apply theme:
```
omarchy-theme-set my-theme
```

Instructions

When creating or modifying Omarchy themes:

Always define all 22 color variables in colors.toml - missing variables cause errors
Use HEX format only (#RRGGBB) - no RGB, HSL, or named colors
Include backgrounds/ directory with at least one wallpaper image
For light themes, create empty light.mode file in theme directory
Test with omarchy-theme-set after changes

For detailed variable usage per application, see reference.md.

What this file has done since we first saw it

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.
