# Hermes Agent Design System

## Overview

Hermes Agent describes itself as: “The official Hermes Agent from Nous Research. A free, open-source AI agent with memory and skills. Download for Mac, Windows or Linux.” The interface is dark, built on **Vivid Indigo (#0000F2)** with **Mist (#F2F2F2)** text, and **Indigo (#0000C2)** as the main accent.

Type is set in **Rules Gothic Condensed** and **Rules Gothic Compressed**. Headlines run large with tight negative tracking; body text is 14px. Depth comes from hairline borders and inset highlights rather than drop shadows. Corners are mostly 3px.

Measured from [hermes-agent.nousresearch.com](https://hermes-agent.nousresearch.com/) on November 5, 2026 at 1440×900 and 390×844 from 287 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 8 roles.

- **Vivid Indigo (#0000F2):** Page background, seen 10 times. Token `background`, CSS `--background-base`.
- **Mist (#F2F2F2):** Primary text and headings, seen 34 times. Token `on-surface`, CSS `--midground`.
- **White 10% (#FFFFFF1A):** Translucent fill for cards and controls, seen 2 times. Token `overlay`.
- **Mist 20% (#F2F2F233):** Stronger translucent fill, seen 1 time. Token `overlay-strong`.
- **Indigo (#0000C2):** Brand color on large areas, seen 2 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Dark Indigo (#000091):** Accent in text, fills and borders, seen 37 times. Token `secondary`.
- **Vivid Indigo (#2828E9):** Accent in logos and imagery. Token `tertiary`.

## Typography

**Rules Gothic Condensed**, **Rules Gothic Compressed**, **Rules Regular**, **Rules Variable**, **Aeonik Fono Pro TRIAL** and **Rules Condensed** share the interface. Fallback stack: `Rules Gothic Condensed, Rules Variable, sans-serif`.

- **headline-display:** Rules Gothic Condensed 108px at weight 200, line height 1, tracking -0.02em (66px on mobile). Page title (h1).
- **headline-lg:** Rules Gothic Condensed 80px at weight 400, line height 1, tracking -0.02em. Section headings (h2).
- **headline-md:** Rules Gothic Compressed 48px at weight 500, line height 1.1 (41px on mobile). Sub-section headings.
- **headline-sm:** Rules Gothic Compressed 32px at weight 400, line height 1.4. Card and feature titles.
- **body-md:** Rules Regular 14px at weight 400, line height 1.43. Body text.
- **body-lg:** Rules Variable 16px at weight 400, line height 1.6. Lead paragraphs.
- **body-sm:** Aeonik Fono Pro TRIAL 10px at weight 400, line height 1.5. Secondary and small text.
- **label-lg:** Rules Condensed 15px at weight 500, line height 1.4, tracking 0.02em. Large buttons and tabs.
- **label-md:** Rules Condensed 14px at weight 500, line height 1. Buttons, navigation and labels.
- **label-sm:** Rules Condensed 12px at weight 400, line height 1, uppercase. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 26% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 5px, md 12px, lg 30px, xl 60px.
- **Sections:** 80px vertical padding between major sections.
- **Gaps:** 30px is the most common gap in flex and grid layouts.

## Elevation & Depth

The design avoids drop shadows. Layers are separated by tonal surface steps and hairline rings:

- `color(srgb 0.380392 0.380392 0.568627 / 0.2) 0px 0px 0px 1px inset`

## Shapes

Most elements use 3px corners. Measured radii, most used first:

- **md (3px):** 60 elements.
- **sm (1.77px):** 26 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“INSTALL HERMES”):** #F2F2F2E6 fill, #0000F2 text, 15px/500, 3px radius, padding 7px 12px.
- **button-secondary (“INSTALL VIA TERMINAL”):** #FFFFFFFA fill, #0000F2 text, 14px/500, 3px radius, padding 0px 10px.
- **button-outline (“: Linux :”):** #0000F2 fill, #F2F2F2 text, 11px/400, padding 6px 12px.
- **button-ghost (“NOUS”):** transparent fill, #F2F2F2 text, 14px/500, 1.775px radius, padding 10px 12px.
- **card:** #0000F2 fill, #F2F2F2 text, 14.2px/400, padding 60px 10px.
- **link:** transparent fill, #F2F2F2 text, padding 0px.

## Do's and Don'ts

- Do use #0000F2 for the page.
- Do use #0000C2 as the brand accent: header, logo and key highlights.
- Do set headlines in Rules Gothic Condensed with tight tracking (-0.02em).
- Do reuse the measured spacing steps (5px, 12px, 30px).
- Do use 3px corners on most elements; larger surfaces also use 1.77px.
- Don't add drop shadows for depth; use hairline rings and borders and contrast.
- Don't introduce new font families beyond Rules Gothic Condensed, Rules Gothic Compressed, Rules Regular, Rules Variable, Aeonik Fono Pro TRIAL and Rules Condensed.
- Don't use #0000C2 for large backgrounds or body text.
- Don't make interface transitions slower than 0.2s.

## Motion

Interface transitions are quick: 0.15s, 0.2s.

- **Easing:** `cubic-bezier(0, 0, 0.2, 1)`, `cubic-bezier(0.4, 0, 0.2, 1)`, `ease`.
