# Hermes Agent — Web UI

Browser-based dashboard for managing Hermes Agent configuration, API keys, and monitoring active sessions.

## Stack

- **Vite** + **React 19** + **TypeScript**
- **Tailwind CSS v4** with custom dark theme
- **shadcn/ui**-style components (hand-rolled, no CLI dependency)

## Development

```bash
# Start the backend API server
cd ../
python -m hermes_cli.main web --no-open

# In another terminal, start the Vite dev server (with HMR + API proxy)
cd web/
npm install
npm run dev
```

Open the **Vite URL** printed in the terminal (usually `http://localhost:5173`). That is the live-reload UI.

`hermes dashboard` on port 9119 serves the **built** bundle from `hermes_cli/web_dist/`, not the Vite dev server — changes in `web/src/` will not appear there until you run `npm run build` and restart the dashboard (or use `web --no-open` + Vite as above).

The Vite dev server proxies `/api` requests to `http://127.0.0.1:9119` (the FastAPI backend).

## Build

```bash
npm run build
```

This outputs to `../hermes_cli/web_dist/`, which the FastAPI server serves as a static SPA. The built assets are included in the Python package via `pyproject.toml` package-data.

## Typography & contrast rules

Read before adding or editing UI styles. These rules keep the dashboard legible across all built-in themes and stop drift back into the patterns the design system was just refactored out of.

### Text size floor

- **Minimum body size: `text-xs` (12px / 0.75rem).** Do not use arbitrary `text-[0.6rem]`, `text-[0.65rem]`, `text-[9px]`, `text-[10px]`, or `text-[11px]` on copy, hints, labels, counts, or badges. Use the standard scale: `text-xs`, `text-sm`, `text-base`.
- Smaller sizes are only acceptable on **decorative overlays** (chart stripes, empty-state icons) — never on text the user is meant to read.

### Opacity floor on text

- **Never apply opacity below 0.7 to text.** No `opacity-30`, `opacity-50`, `opacity-60` on `<span>`s, `<p>`s, labels, etc.
- **Do not stack opacity tokens.** Patterns like `text-muted-foreground/60`, `text-midground/70`, `text-foreground/50` create unpredictable WCAG failures because the parent token already has alpha.
- Use the **semantic text tokens** from `@nous-research/ui`'s `globals.css`:
  - `text-text-primary` — default body text.
  - `text-text-secondary` — subtitles, meta, inactive nav.
  - `text-text-tertiary` — small chrome labels, counts, footnotes.
  - `text-text-disabled` — disabled states.
  - `text-text-on-accent` — text on filled accent surfaces.

### Brand uppercase via `text-display`, not raw `uppercase`

- The dashboard preserves the Nous brand uppercase aesthetic, but it is **opt-in per element, not global**.
- Apply uppercase via the DS utility `text-display` on **brand chrome only** — page titles, nav section headings, badges, brand wordmark. DS components (`Button`, `Badge`, `Tabs`, `Segmented`, etc.) already self-apply `text-display`.
- **Do not introduce new `uppercase`** (the literal Tailwind class) in `hermes-agent/web/src`. Prefer `text-display` for new brand chrome. Legacy `uppercase` call sites (e.g. `components/ui/label.tsx`, `card.tsx`) remain until migrated.
- The app shell no longer forces uppercase globally, so blanket `normal-case` opt-outs are unnecessary. Use `normal-case` only where a DS component applies `text-display` but the label should stay sentence case — e.g. dynamic user content (model slugs, theme names) **or** fixed UI copy that is not brand chrome (EnvPage “not configured” toggle, sidebar “New chat”).

### Fonts

Typography is **opt-in per surface**, not global on layout shells — the app shell and page header keep their original theme/expanded fonts; Mondwest applies only where explicitly set.

| Tier | Classes | Use for |
|------|---------|---------|
| Brand chrome | `font-mondwest text-display` (or `themedChrome`) | Sidebar nav, card section headers (`CardTitle`), Segmented filter buttons, filter panel headings |
| Themed body | `font-mondwest normal-case` (or `themedBody`) | Card content (`Card`, `CardDescription`), session/platform rows, analytics tables — **scoped to the component** |
| Page chrome | `font-expanded` | Page header h1 (`PageHeaderProvider`) — sentence case, not `text-display` |
| Wordmark | `Typography` + size/tracking only | Sidebar/mobile “Hermes Agent” — mixed case, no Mondwest, no `text-display` |
| Technical | `font-mono-ui` / `font-mono` / `font-courier` | Model slugs, env keys, schedules, YAML, repo URLs |

- Do **not** put `themedBody` or `themedFont` on `<main>`, `App`, or other layout wrappers — it overrides component-scoped styles.
- **`Card`** applies `themedBody`; **`CardTitle`** uses `text-display` (uppercase chrome); **`CardDescription`** uses `themedBody`.
- **`NouiTypography`** defaults to `font-sans` unless a font prop is passed.
- Do **not** use raw `font-sans` or `font-display` (theme sans variable) on new dashboard UI — prefer Mondwest tiers above where brand-appropriate.

### Color tokens

- Prefer **semantic tokens** (`text-text-*`, `bg-card`, `border-border`, `text-foreground`, `text-destructive`, `text-success`, `text-warning`) over raw layer references (`text-midground`, `text-foreground`).
- `text-muted-foreground` is now wired to `--color-text-secondary`, so existing call sites stay correct, but new code should prefer the semantic name.
- When you genuinely need a non-token color (icon de-emphasis on a chart, terminal foreground via inline style), keep alpha at `≥ 0.7` for any text.
