Orkas is a desktop application for commanding a team of AI agents through one chat, with a commander model assigning work to specialist agents in parallel or in sequence. People use it to coordinate research, writing, presentations, and software tasks while keeping files on their computer. The catalogue includes skills for extending the agents available to Orkas.
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.

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 | $0.00002 | $0.00701 |
| Opus 5 | $0.00001 | $0.00351 |
| Sonnet 5 | $0.00000 | $0.00140 |
| Haiku 4.5 | $0.00000 | $0.00070 |
Grade A, and why
ui-color 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ui-color
Use this skill when creating or reviewing palettes, contrast, semantic color, dark mode, or chart colors. It adapts Color Expert-style color reasoning into practical UI work.
Color Roles First
Start with roles before choosing hues:
bg: page background.surface: panels, rows, cards, inputs.surface-raised: dialogs, menus, popovers.text: primary content.text-muted: metadata and helper text.border: dividers, input outlines, table rules.accent: primary action, selection, active state.focus: visible keyboard focus.danger,warning,success,info: semantic states.chart-*: data series, separate from action colors.
Do not use the same accent for primary action, warning, and chart series.
OKLCH And Perceptual Rules
When authoring new palettes:
- Prefer OKLCH/OKLAB reasoning for even lightness and chroma steps.
- Keep neutral surfaces low-chroma.
- Use accent chroma deliberately; high chroma should be rare in work tools.
- Build light and dark variants by role, not by automatic inversion.
- Keep semantic colors distinct in hue and lightness.
When the codebase uses hex, HSL, RGB, or CSS variables, implement in the local format while preserving the role logic.
Contrast Rules
Check contrast for:
- Body text on page and panel backgrounds.
- Muted text on surfaces.
- Buttons in default, hover, pressed, and disabled states.
- Inputs, focus rings, and validation messages.
- Table row selection and hover.
- Status chips and alerts.
- Chart labels and legends.
Do not rely on color alone for state. Pair semantic colors with text, icon shape, position, or pattern.
Palette Construction
For product UI:
- Use 1 primary accent.
- Add at most 1 secondary accent unless data visualization requires more.
- Keep neutral scale broad enough for hierarchy.
- Keep borders visible but quiet.
- Reserve saturated colors for action, selection, and status.
For dashboards:
- Separate categorical chart colors from UI actions.
- Avoid too many similar blues or purples.
- Make critical alerts readable in both color and text.
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.

ui-color is a skill published in the GitHub repository Orkas-AI/Orkas (1,885 stars, last pushed today), licensed MIT. It adds 2 tokens to every session and 701 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
