description: Single source of truth for code naming, i18n translation glossary, and Chinese voice guide.
---

This page is the single source of truth for code naming, the i18n translation glossary, and the Chinese voice guide. Anything that used to live in `packages/views/locales/glossary.md` or in scattered comments now lives here.

If you write Multica code, change a translation, or write Chinese product copy, this is the page to reference.

## 1. Code naming

### Routes

Pre-workspace routes (the routes that exist before the user is in a workspace) MUST use either a single word or the `/{noun}/{verb}` pattern.

- ✅ `/login`, `/inbox`, `/workspaces/new`
- ❌ `/new-workspace`, `/create-team`, `/accept-invite`

Hyphenated word groups at the root collide with user-chosen workspace slugs and force endless reserved-slug audits. Reserving the noun (`workspaces`) automatically protects the entire `/workspaces/*` subtree.

### Workspace-scoped routes

Always live under `/{slug}/{section}` — `/{slug}/issues`, `/{slug}/agents`, `/{slug}/settings`. Never duplicate workspace routing logic; use `useNavigation().push()` from shared code, never framework-specific link APIs.

### Packages and modules

The monorepo enforces strict package boundaries:

| Package | May depend on | Must NOT depend on |
| --- | --- | --- |
| `packages/core` | nothing app-specific | `react-dom`, `localStorage`, `process.env`, `next/*`, UI libraries |
| `packages/ui` | nothing | `@multica/core`, business logic |
| `packages/views` | `core/`, `ui/` | `next/*`, `react-router-dom`, stores |
| `apps/web/platform/` | `next/*` | other apps |
| `apps/desktop/.../platform/` | `react-router-dom`, electron | other apps |

If logic appears in both apps, it MUST be extracted to a shared package. There are no exceptions for "small" duplication.

### Files and components

- Files: `kebab-case.tsx` / `kebab-case.ts` (e.g. `agent-row-actions.tsx`)
- Components: `PascalCase` (e.g. `AgentRowActions`)
- Hooks: `useCamelCase` (e.g. `useWorkspaceId`)
- Tests: colocated as `<file>.test.ts(x)`
- Stores (Zustand): `<feature>-store.ts`, exported as `use<Feature>Store`

### Database (Go + sqlc)

- Tables: `snake_case` singular (`user`, `workspace`, `agent_runtime`)
- Columns: `snake_case` (`workspace_id`, `created_at`, `last_seen_at`)
- Foreign keys: `<table>_id`
- Booleans: `is_<state>` or `<state>_at` (timestamp form preferred for state changes)
- Migration files: `NNN_descriptive_name.up.sql` + `.down.sql` — always provide both directions

### Go

- Standard `gofmt` + `go vet`. No exceptions.
- Handler files mirror domain: `agent.go`, `auth.go`, `runtime.go`
- Tests: `<file>_test.go` colocated
- For UUID parsing in handlers, follow the rule in the root `CLAUDE.md` — `parseUUIDOrBadRequest` for boundary input, `parseUUID` (panicking) for trusted round-trips, never `util.ParseUUID` directly without checking the error.

### TypeScript

- API responses on the wire are `snake_case`; the api client converts to `camelCase` at the boundary. Inside TS code, **always camelCase**.
- Types: `PascalCase` (`Issue`, `AgentRuntime`); never `IPrefix`, never `_t` suffix.
- Enums: prefer string literal unions; reserve `enum` for runtime-iterable cases.
- TanStack Query keys: factory functions in `<feature>/queries.ts`, e.g. `issueKeys.detail(id)`.

### Issue keys

Every issue has a human-readable key like `MUL-123`: workspace `issue_prefix` (3 letters, uppercase) + sequence number. The prefix is set at workspace creation and is never changed afterward.

### Comments in code

English only. The repo enforces this for both Go and TypeScript. If you find a Chinese comment in code, it's a bug — replace it.

### Commit messages

Conventional format: `feat(scope)`, `fix(scope)`, `refactor(scope)`, `docs`, `test(scope)`, `chore(scope)`. Atomic commits grouped by intent.

## 2. i18n translation glossary

This is the **mandatory** glossary for every translation PR. It used to live at `packages/views/locales/glossary.md`; that file is now a stub pointing here.

### The core distinction: entity vs concept

Multica's product nouns split into two categories:

- **Entity** — has a URL, a database row, an API type. In Chinese text, render as **lowercase English** so it visually reads like a type name and signals "this is a Multica system entity".
- **Concept** — generic noun, not a database entity. **Translate fully** so Chinese users don't see jagged English embedded in flowing text.

This rule is aligned with `apps/docs/content/docs/*.zh.mdx` — the docs are the de facto Chinese voice standard and have been battle-tested across 20+ pages.

### Entities — mixed rule (`issue` / `skill` / `task`)

`issue` / `skill` / `task` are Multica's core entities. They have schema columns, API fields, and product UI labels that are all English. In Chinese text, they follow a **mixed rule** — what to use depends on where the word appears:

| Context | Render | Example |
| --- | --- | --- |
| **UI strings, state names, code references** | lowercase English | "排队中的 task"、"创建子 issue"、"为智能体注入 skill" |
| **Doc titles / section headings** | Title-case English **or** the Chinese term | "Issue 与 project"、"Skills"、"执行任务" |
| **Long-form doc prose, when the entity is the running subject** | Chinese term, with English in parentheses on first mention | "**执行任务**（task）是智能体每一次工作的单位" |
| **API / DB fields** | always `task` / `issue` / `skill` | `task_id`, `issue_status`, `skill_uuid` |

Chinese term reference:

- `task` ↔ `执行任务` (or shortened to `任务` once context is clear)
- `issue` has no settled Chinese translation — leave English; titles may capitalize as `Issue`
- `skill` has no settled Chinese translation — leave English; titles may capitalize as `Skills`

**Why `issue` / `skill` / `task` aren't forced into Chinese the way `project` / `autopilot` are**:

- **`issue` / `task`**: dev teams talk in English. The Chinese candidates ("任务" — too vague, almost synonymous with "工作"; "工单" — IT ticket connotation; "议题" — GitHub-style but doesn't match the product feel) all read worse than `issue`. **But** in long-form doc prose, repeating lowercase `task` 50× breaks the rhythm — so prose is allowed to use `执行任务`, while UI strings and state names stay lowercase English.
- **`skill`**: Multica-specific concept with no established Chinese term.
- **`project` → "项目"**: settled mainstream Chinese word. Feishu / Tower / Teambition / PingCode / GitHub Projects — every Chinese product translates it. No product keeps `project` in Chinese context.
- **`autopilot` → "自动化"**: in Chinese, "autopilot" associates with Tesla's "自动驾驶" and doesn't match what the feature does (run tasks on a schedule). Notion and Feishu both use "自动化"; that's the industry consensus.

### Don't translate — brands and acronyms

| Category | Terms |
| --- | --- |
| Brands | **Multica**, GitHub, Slack, Google, Anthropic, OpenAI, Claude, Codex, Cursor, Linear, Jira |
| Acronyms | API, CLI, URL, SDK, OAuth, JWT, SSO, WebSocket, HTTP, JSON, YAML, SQL |

### Translate fully — concepts

| English | Chinese |
| --- | --- |
| Workspace | **工作区** |
| Agent | **智能体** |
| Project | **项目** |
| Autopilot | **自动化** |
| Daemon | **守护进程** |
| Runtime | **运行时** |
| Inbox | **收件箱** |
| Comment | **评论** |
| Reply | **回复** |
| Notifications | **通知** |
| Member | **成员** |
| Label | **标签** |
| Settings | **设置** |
| Onboarding | **上手引导** |

### Translate fully — generic UI words

| Date / Time | 日期 / 时间 |
| Today / Yesterday / Tomorrow | 今天 / 昨天 / 明天 |
| Empty / Failed / Success | 空 / 失败 / 成功 |
| Error / Warning | 错误 / 警告 |

### Roles and status enums (lowercase English, not translated)

These are schema-level identifiers; render as lowercase English even in Chinese context.

- Roles: `owner` / `admin` / `member`
- Issue status: `backlog` / `todo` / `in_progress` / `in_review` / `done` / `blocked` / `cancelled`

In UI, surface them in English (optionally `code-style` wrapped):

- "你需要 owner 权限"
- "已切换到 in_progress"

### Word combination rules

Always put **a single space** between an English word (entity / brand / acronym) and surrounding Chinese:

- "Create new issue" → "新建 issue"
- "Assign to agent" → "分配给智能体"
- "Configure runtime" → "配置运行时"
- "Stop daemon" → "停止守护进程"

### Plurals and counts

i18next uses `_one` / `_other`; Chinese has no grammatical number, only fill `_other`.

```json
// en/issues.json
{
  "issue_count_one": "{{count}} issue",
  "issue_count_other": "{{count}} issues"
}

// zh-Hans/issues.json
{
  "issue_count_other": "{{count}} 个 issue"
}
```

Common count formats:

- `{{count}} issues` → `{{count}} 个 issue`
- `{{count}} agents` → `{{count}} 个智能体`
- `{{count}} workspaces` → `{{count}} 个工作区`
- `{{count}} comments` → `{{count}} 条评论`
- `{{count}} members` → `{{count}} 位成员`
- `{{count}} skills` → `{{count}} 个 skill`

### Interpolation

Use `{{var}}`. Chinese translations may reorder for natural sentence flow.

```json
// en
{ "welcome_message": "Welcome back, {{name}}!" }

// zh-Hans
{ "welcome_message": "欢迎回来，{{name}}！" }
```

### Translation key naming

Three-level nesting: `feature.component.action`.

```json
{
  "feature_or_component": {
    "subcomponent_or_section": {
      "action_or_label": "..."
    }
  }
}
```

Examples:

- `issues.toolbar.batch_update_success`
- `issues.detail.comment_form.placeholder`
- `inbox.empty.title`
- `settings.preferences.language.title`

### Web-only / desktop-only copy

- Shared copy: top level of the namespace JSON
- Web-only: `web` section
- Desktop-only: `desktop` section

See `auth.json` for the canonical example (the `web` section contains `prefer_desktop` / `desktop_handoff.*`).

## 3. Chinese voice and style

### Punctuation

- Full-width punctuation in Chinese: `，。：；！？`
- Quotes: straight double quotes `"..."` to match the English source. Do not use `「」` or curly quotes.
- Ellipsis: three dots `...` not the single character `…`. Match the English source.
- Mixed Chinese-English: a single space on each side of the English word (see Word combination rules).

### Style principles

- **Concise and direct.** Avoid translation-ese: "对于 X 来说"、"作为 X"、"我们的"。
- **Error messages**: gentle but clear. "无法保存修改" beats "保存修改失败了！".
- **Buttons**: verb first, 2–4 characters. "取消"、"保存修改"、"立即同步".
- **Tooltips**: full short sentence. "复制链接到剪贴板".
- **Placeholders**: example-style. "输入 issue 标题...".

### Where to look when in doubt

When the glossary doesn't cover a term, look at:

1. `apps/docs/content/docs/*.zh.mdx` — the de facto Chinese voice standard, 20+ pages of consistent translation
2. `packages/views/locales/zh-Hans/auth.json` and `editor.json` — JSON structure + selector API patterns
3. `packages/views/auth/login-page.tsx` — component-level selector API call site
4. `packages/views/settings/components/preferences-tab.tsx` — language switcher reference

## Updating this page

If you change a rule here, also:

1. Apply it in the relevant locale JSONs / CLAUDE.md / docs page
2. Note the change in the PR description so reviewers know to look for downstream sweep

This page is the contract; nothing else overrides it.
