# Agent Orchestrator — Design System
|
||
|
||
A local, single-tenant agent orchestration platform. Users submit natural-language tasks via a small Japanese-language admin UI; an LLM classifier routes each task into a named **Piece** (workflow), which runs a multi-step **Movement** chain against local Ollama workers and emits progress/results back to the UI as chat-style comments.
|
||
|
||
## Product at a glance
|
||
|
||
- **One product, one surface:** a React + Vite + TailwindCSS admin dashboard at `/ui/` on the orchestrator server (`http://this-machine:9876/ui/`). Mobile (single-column), tablet (list + chat), desktop (list + chat + detail) layouts.
|
||
- **Language:** Japanese throughout (UI labels, empty states, toasts). Latin/mono treatment reserved for identifiers, status keywords, version tags, wordmark.
|
||
- **Primary objects:** Task → Job → Movement → Tool call. Status kanban: `queued / running / waiting_human / waiting_subtasks / retry / succeeded / failed / cancelled`.
|
||
- **Interaction model:** a threaded chat with progress cards interleaved between user requests and agent results (green = result, amber = ASK, blue bubble = user, grey pill card = progress).
|
||
|
||
## Sources consulted
|
||
- **Codebase (read-only local mount):** `gitea-agent-orchestrator/`
|
||
- `ui/tailwind.config.js`, `ui/src/index.css` — tokens, fonts
|
||
- `ui/src/lib/utils.ts` — `statusTone()`, `relativeTime()`, activity parsing
|
||
- `ui/src/components/**` — TopBar, FilterBar, TaskListItem, ChatPane, ChatMessage, DetailHeader, OverviewTab, ProgressTab, CreateTaskDialog, EmptyState, StatChip, StatusBadge, LoadingSpinner
|
||
- `ui/public/favicon.svg` — the "hub + 3 agents" mark
|
||
- `README.md` (root) — product narrative, piece list, tool registry
|
||
- **No Figma, no slide templates, no marketing site** were provided; this design system documents the existing admin UI only.

## Content fundamentals
|
||
|
||
**Voice.** Terse, functional, Japanese. Almost no marketing flourish. Labels are nouns or imperative verbs — "新しい依頼" (new request), "Task 作成" (create Task), "詳細" (details), "送信" (send), "共有停止" (stop sharing).
|
||
|
||
**Person.** Neither "あなた" nor "私" — the UI talks about objects, not people. Empty state uses a numbered list of actions ("左パネルからタスクを選択する" — "select a task from the left panel") rather than second-person.
|
||
|
||
**Case & casing.**
|
||
- Japanese sentences where there's human prose.
|
||
- English identifiers kept English, capitalized as in code: **Tasks / Schedules / Settings / Users** (TopBar navs), **Inbox / Running / Waiting / Subtasks / Retry / Done / Failed / Cancelled** (status columns). These are not translated, even in a Japanese UI.
|
||
- Meta labels are SMALL-CAPS UPPERCASE with wide tracking in the mono face: `STEP`, `TOOL`, `PREVIEW`, `FINAL`, `ASK`, `LOG`.
|
||
- "Agent Orchestrator" wordmark: uppercase, mono, letter-spacing: 0.16em, blue-600.
|
||
- Product name "agent-orchestrator" in kebab-case in docs; UI header is Title Case.
|
||
|
||
**Example strings** (verbatim from code):
|
||
- `新しい依頼` (new request) — primary CTA
|
||
- `スレッドを選択してください` (please select a thread) — empty state title
|
||
- `左の一覧から選ぶと、会話、進捗、成果物を追えます。` — empty state description
|
||
- `メッセージを入力... (Ctrl+Enter で送信)` — composer placeholder
|
||
- `まだ進行情報がありません。` (no progress info yet)
|
||
- `(activity.log がまだありません)` — empty log fallback
|
||
- `良かった` / `改善が必要` — feedback thumbs labels
|
||
|
||
**Numbers & units.** Counts render as `<bold number> 件` (items), `<bold number> 実行中` (running), `<bold number> 待機` (waiting). Relative time in Japanese: `たった今 / N分前 / N時間前 / N日前`. Durations mix units: `ms`, `s`, `m Ns`.
|
||
|
||
**Tone.** Operator-facing, not consumer-facing. No exclamation marks, no emoji in UI chrome. Emoji appear only as **domain signals inside agent content**: 👍 / 👎 on feedback buttons, 📋 on checklist progress cards. Unicode symbols (☑ ✗ ⊘ ☐ ▶) are used as list markers inside agent-emitted checklists. Do not introduce new emoji outside these established spots.
|
||

|
||
## Visual foundations
|
||
|
||
**Palette.** A near-monochromatic slate neutral scale (Tailwind `slate-50…900`) carrying the entire surface, with **#2563eb (blue-600)** as the only brand color for primary actions, active states, focus rings, and the logo. Semantic status pills add pastel bg / deep fg pairs: green (running/success), amber (waiting/retry), indigo (subtasks), red (failed), blue (succeeded/queued edge cases), slate (queued/cancelled). All defined verbatim in `statusTone()` in `ui/src/lib/utils.ts`.
|
||
|
||
**Type.** `IBM Plex Sans JP` for everything, `IBM Plex Mono` for identifiers, log output, version tags, wordmark, cron expressions, and the micro-label uppercase treatment. Body is **13px** — small and dense. Titles jump to 18px (detail) or 20px (dialog); chat bubbles are 14px leading-relaxed. Mobile forces input `font-size: 16px !important` to prevent iOS auto-zoom.
|
||
- *Font substitution note:* IBM Plex is already loaded from Google Fonts in the codebase; no substitution required.
|
||
|
||
**Weight.** Heavy. 700 ("bold") is the workhorse — buttons, pill labels, status chips, even 10px/11px micro labels. 800 ("extra-bold") is reserved for titles and primary CTAs. 400/500 appear in body copy only.
|
||
|
||
**Spacing.** Tailwind 4px scale. Gutters between panels are `8px` (`p-2 gap-2`). Cards pad `16px` (`p-4`). Buttons pad `6px 10px` (small chips), `8px 16px` (primary). The desktop layout is a 3-column grid: `clamp(240px, 22vw, 280px)` list / flexible chat / `clamp(280px, 26vw, 440px)` detail (or `clamp(360px, 30vw, 560px)` wide).
|
||
|
||
**Backgrounds.** Flat solid colors — **never gradients**. App root is `#f3f6fb` (between slate-50 and slate-100); content cards are white. Activity log switches to an inverted surface: `bg-slate-900 text-slate-100` as a "terminal" zone. No illustrations, no patterns, no photos, no blur/glassmorphism.
|
||
|
||
**Animation.** Minimal and purposeful. Only three motion idioms:
|
||
1. `transition-colors` on hover/active states (Tailwind default ~150ms).
|
||
2. `animate-pulse` on a 2px blue dot while a job is running.
|
||
3. `animate-spin` on the loading spinner (2px slate-200 border, blue-600 top-border).
|
||
No fades, no slides, no springs, no bounces. Expand/collapse caret rotates 90° (`rotate-90`) on click.
|
||
|
||
**Hover states.** Buttons and list items darken one step: transparent → `bg-slate-100`, `bg-blue-600` → `bg-blue-700`, border-slate-200 → border-slate-300. Text links: `hover:underline` only on small text actions. No scale, no shadow-lift.
|
||
|
||
**Press / active states.** Active navigation uses **filled accent**: `bg-blue-600 text-white`. Active filter pills use **tinted** style: `border-blue-600 bg-blue-50 text-blue-700`. Active list item: `border-blue-500 bg-blue-50`. No shrink, no darken-further.
|
||
|
||
**Focus.** `focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-blue-500`. Inputs on focus: `focus:border-blue-400 focus:ring-2 focus:ring-blue-100`.
|
||
|
||
**Borders.** 1px, `#e2e8f0` (slate-200) by default. Active states promote to `slate-300` (hover) or `blue-500/600` (selected). Chat bubbles have no border on the user (blue-filled) bubble but do on ask/result bubbles to soften the pastel.
|
||
|
||
**Shadows.** Two tiers only:
|
||
- `shadow-sm` — resting card (every panel, chip, list item). Nearly invisible, but cards in Vite have it.
|
||
- `shadow-2xl` — Dialog overlay only.
|
||
No colored shadows, no inner shadows, no glows.
|
||
|
||
**Radii (heavy rounding).** The product reads "rounded" first, flat second.
|
||
- `rounded-lg` (8px): small selects, small buttons, rotating caret container, log surface.
|
||
- `rounded-xl` (12px): **default** — cards, buttons, inputs, list items, panels.
|
||
- `rounded-2xl` (16px): dialogs, chat bubbles (tail reduced to `rounded-br-md` / `rounded-bl-md`).
|
||
- `rounded-full` (9999px): status pills, filter tabs, avatar, pulse dot.
|
||
|
||
**Transparency & blur.** Modal overlay uses `bg-slate-900/50` or `bg-black/40` — straight alpha, no backdrop-blur. No frosted chrome anywhere.
|
||
|
||
**Cards.** White fill, 1px slate-200 border, `rounded-xl`, `shadow-sm`. Padded `p-3` or `p-4`. The admin list panel is itself a card; list items inside are nested mini-cards with the same recipe.
|
||
|
||
**Chat bubbles.**
|
||
- User: `rounded-2xl rounded-br-md`, `bg-blue-600 text-white`, `shadow`.
|
||
- Agent ASK: `rounded-2xl rounded-bl-md`, `bg-amber-50 border border-amber-200`, `shadow-sm`.
|
||
- Agent RESULT: `rounded-2xl rounded-bl-md`, `bg-green-50 border border-green-200`, `shadow-sm`, renders Markdown.
|
||
- Progress card: centered, `bg-slate-50 border border-slate-200 rounded-xl`, 12px slate-500 text, click-to-expand.
|
||
|
||
**Protection gradients vs capsules.** Never gradients. Always capsules/pills for chips and status, always rectangular cards for containers.
|
||
|
||
**Imagery vibe.** The brand has no photography. The single branded image is the `favicon.svg`: a rounded blue square with a white central "hub" and three satellite nodes connected by thin 55%-opacity white lines — a literal orchestrator-connecting-workers glyph. Keep this as the only decorative asset unless explicitly asked.
|
||
|
||
**Layout rules.** Fixed TopBar at top (white, slate-200 bottom border). Main content fills remaining `h-dvh` and is `overflow-hidden` at the root — panels handle their own scroll. Toasts slide in at the top-center (`mx-4 mt-2`). Dialogs center-screen, `max-width: min(860px, 92vw)`, `max-height: 88dvh`, scroll internally.
|
||

|
||
## Iconography
|
||
|
||
**No icon font, no icon library dependency.** Icons are inline SVG written directly in components, drawn at `w-3.5 h-3.5`, `w-4 h-4`, or `w-5 h-5`, stroke-based, `stroke-width="2"`, `strokeLinecap="round"`, `strokeLinejoin="round"`, `fill="none"`. Style is close to **Lucide / Feather** — 2px stroke, round caps, 24×24 viewBox, minimal. Example glyphs in source: magnifying-glass (search), paperclip (attach), cross (close), VNC monitor square, chevron-right caret.
|
||
|
||
**Substitution policy.** When extending the system, prefer **Lucide** (`https://unpkg.com/lucide-static`) or hand-write a 2px-stroke, round-cap, 24×24 SVG inline. Do **not** introduce Heroicons solid, Material, or Phosphor — those break the line-weight consistency.
|
||
|
||
**Unicode glyphs** are used functionally inside agent-generated content:
|
||
- `☑ ✗ ⊘ ☐` — checklist item states (done / failed / skipped / pending)
|
||
- `▶` — expand caret (rotates to down)
|
||
- `×` — close buttons within attachment chips
|
||
- `✕` — mobile dialog close
|
||
- `+` / `＋` — add/create indicators
|
||
- `·` — meta separator (`worker: … · mode: …`)
|
||
|
||
**Emoji.** Deliberately limited:
|
||
- 👍 / 👎 — feedback rating only
|
||
- 📋 — checklist progress card header only
|
||
|
||
Do not introduce new emoji. When agent markdown renders emoji, the `prose` plugin styles them at 14px inline — do not restyle.
|
||
|
||
**Logo usage.** The 32×32 favicon is the only mark. Minimum size 16×16. Clear space: `x/4` on all sides where `x` is the square's edge. Do not recolor the blue fill; if placing on blue, invert to a white square with blue contents.
|
||

## Component notes (see `ui_kits/admin/`)
|
||
|
||
The admin UI kit recreates: TopBar, FilterBar, TaskListItem, TaskListPanel, ChatPane, ChatMessage (user/ask/result/progress variants), DetailPanel with tab pills, StatusBadge, StatChip, EmptyState, LoadingSpinner, CreateTaskDialog, and the composite desktop 3-column layout.
|
||
|
||
## Caveats
|
||
|
||
- No external brand guide, marketing site, or Figma was provided — this system is derived strictly from the live admin UI source.
|
||
- No printed/decorative imagery exists in the codebase; the only "brand asset" is the favicon logo.
|
||
- Fonts load from Google Fonts CDN (same as production); no local TTFs needed.
