# Skills UI Feature Design
## Overview
Port the CLI `/skills` listing to the Desktop Web APP, adding a full Skills browser with file tree navigation and content preview in the Settings page.
## Architecture
```
Desktop UI (React) Server (Bun.serve) Filesystem
┌──────────────────┐ ┌──────────────────┐ ┌──────────────────┐
│ Settings Page │ │ GET /api/skills │ │ ~/.claude/skills/│
│ └─ Skills Tab │──────▶│ → list meta │──────▶│ ./.claude/skills/│
│ ├─ SkillList │ │ │ │ plugins cache/ │
│ └─ SkillDetail │ GET /api/skills/ │ │ bundled skills/ │
│ ├─ FileTree│──────▶│ detail?s=&n= │──────▶│ │
│ └─ Viewer │ │ → tree + files │ │ │
└──────────────────┘ └──────────────────┘ └──────────────────┘
```
## Data Models
### SkillMeta (list item)
```typescript
type SkillSource = 'userSettings' | 'projectSettings' | 'policySettings'
| 'plugin' | 'mcp' | 'bundled'
type SkillMeta = {
name: string // unique name (plugin format: "plugin:skill")
displayName?: string // custom display name from frontmatter
description: string
source: SkillSource
userInvocable: boolean
version?: string
contentLength: number // char count for token estimation
pluginName?: string // plugin name when source is 'plugin'
hasDirectory: boolean // whether the skill has a browsable directory
}
```
### FileTreeNode
```typescript
type FileTreeNode = {
name: string // file/dir name
path: string // relative to skill root
type: 'file' | 'directory'
children?: FileTreeNode[] // present for directories
}
```
### SkillFile
```typescript
type SkillFile = {
path: string // relative path
content: string // file content
language: string // language id (md, ts, json, yaml, sh, etc.)
}
```
### SkillDetail (detail view)
```typescript
type SkillDetail = {
meta: SkillMeta
tree: FileTreeNode[] // directory tree
files: SkillFile[] // all file contents, loaded at once
skillRoot: string // absolute path (display only)
}
```
## Server API
### `GET /api/skills`
Returns metadata list of all installed skills.
**Response:**
```json
{
"skills": [
{
"name": "my-skill",
"displayName": "My Skill",
"description": "Does something useful",
"source": "userSettings",
"userInvocable": true,
"contentLength": 1234,
"hasDirectory": true
}
]
}
```
**Implementation:** Reuse `loadAllCommands()` from `src/commands.ts`, filter for `type === 'prompt'` commands with skill-related `loadedFrom` values. Extract metadata without loading full content.
### `GET /api/skills/detail?source={source}&name={name}`
Returns full skill data including file tree and all file contents.
**Response:**
```json
{
"detail": {
"meta": { ... },
"tree": [
{ "name": "SKILL.md", "path": "SKILL.md", "type": "file" },
{
"name": "examples",
"path": "examples",
"type": "directory",
"children": [
{ "name": "demo.ts", "path": "examples/demo.ts", "type": "file" }
]
}
],
"files": [
{ "path": "SKILL.md", "content": "---\nname: ...\n---\n# ...", "language": "md" },
{ "path": "examples/demo.ts", "content": "...", "language": "ts" }
],
"skillRoot": "/Users/x/.claude/skills/my-skill"
}
}
```
**Implementation:**
1. Find matching skill by source + name from loaded commands
2. Get `skillRoot` from the command object
3. Recursively walk the directory, skip `node_modules`, `.git`, hidden dirs
4. Read all files (max 100KB per file, max 50 files total as safety limit)
5. Detect language from file extension
6. For MCP skills (no directory): return empty tree, single virtual file with the skill's prompt content
### File: `src/server/api/skills.ts`
New file following the pattern of `src/server/api/status.ts`.
### Router registration: `src/server/router.ts`
Add `case 'skills': return handleSkillsApi(req, url, segments)`.
## Desktop UI
### Settings Tab Addition
Add a 5th tab "Skills" (icon: `auto_awesome`) to `desktop/src/pages/Settings.tsx`.
```
type SettingsTab = 'providers' | 'permissions' | 'general' | 'adapters' | 'skills'
```
### Skill List View (`SkillList.tsx`)
- Grouped by source (User, Project, Plugin, MCP, Bundled)
- Each group: collapsible header with count
- Each item: name, description (truncated), source badge
- Click → navigate to detail view
- Loading state + empty state
### Skill Detail View (`SkillDetail.tsx`)
Two-panel layout:
- **Left panel (w-[220px]):** File tree with expand/collapse
- **Right panel (flex-1):** File content viewer
- **Header:** Back button, skill name, description, source badge, token estimate
- Default selected file: SKILL.md
### File Tree Component (`FileTree.tsx`)
- Recursive tree with indent
- Directory expand/collapse (default: all expanded)
- File icons based on extension
- Click file → show in right panel
- Active file highlight
### File Viewer (`FileViewer.tsx`)
- For `.md` files: Use existing `MarkdownRenderer`
- For code files: Use existing `CodeViewer` with language detection
- File path header with copy button
- Scrollable content area
### Language Detection
Map file extension to language:
```typescript
const LANG_MAP: Record<string, string> = {
md: 'markdown', ts: 'typescript', tsx: 'typescript',
js: 'javascript', jsx: 'javascript', json: 'json',
yaml: 'yaml', yml: 'yaml', sh: 'bash', bash: 'bash',
py: 'python', toml: 'toml', css: 'css', html: 'html',
}
```
## State Management
### `desktop/src/stores/skillStore.ts`
```typescript
type SkillStoreState = {
skills: SkillMeta[]
selectedSkill: SkillDetail | null
isLoading: boolean
isDetailLoading: boolean
error: string | null
fetchSkills: () => Promise<void>
fetchSkillDetail: (source: string, name: string) => Promise<void>
clearSelection: () => void
}
```
### `desktop/src/api/skills.ts`
```typescript
export const skillsApi = {
list: () => api.get<{ skills: SkillMeta[] }>('/api/skills'),
detail: (source: string, name: string) =>
api.get<{ detail: SkillDetail }>(`/api/skills/detail?source=${encodeURIComponent(source)}&name=${encodeURIComponent(name)}`),
}
```
### `desktop/src/types/skill.ts`
All type definitions from Data Models section.
## i18n
Add to both `en.ts` and `zh.ts`:
```typescript
'settings.tab.skills': 'Skills' / '技能',
'settings.skills.title': 'Installed Skills' / '已安装技能',
'settings.skills.description': 'Skills extend Claude...' / '技能扩展 Claude...',
'settings.skills.empty': 'No skills installed' / '暂无已安装技能',
'settings.skills.back': 'Back to list' / '返回列表',
'settings.skills.tokens': '~{count} tokens',
'settings.skills.files': '{count} files' / '{count} 个文件',
'settings.skills.source.userSettings': 'User' / '用户',
'settings.skills.source.projectSettings': 'Project' / '项目',
'settings.skills.source.plugin': 'Plugin' / '插件',
'settings.skills.source.mcp': 'MCP',
'settings.skills.source.bundled': 'Built-in' / '内置',
```
## Files to Create/Modify
### New files (7):
1. `src/server/api/skills.ts` — Server API handler
2. `desktop/src/types/skill.ts` — Type definitions
3. `desktop/src/api/skills.ts` — API client
4. `desktop/src/stores/skillStore.ts` — Zustand store
5. `desktop/src/components/skills/SkillList.tsx` — Skill list component
6. `desktop/src/components/skills/SkillDetail.tsx` — Detail view (FileTree + FileViewer inline)
### Modified files (4):
7. `src/server/router.ts` — Add skills route
8. `desktop/src/pages/Settings.tsx` — Add Skills tab
9. `desktop/src/i18n/locales/en.ts` — English translations
10. `desktop/src/i18n/locales/zh.ts` — Chinese translations
## Design Decisions
1. **One detail request loads all files** — Single skill directories are small (typically <50KB total), so loading all at once avoids per-file request overhead.
2. **Reuse existing components** `MarkdownRenderer` for .md files, `CodeViewer` for code. No new rendering dependencies.
3. **source + name as identifier** Skills can have duplicate names across sources, so both are needed.
4. **Server-side skill loading** Reuse `loadAllCommands()` which already handles all 6 sources with deduplication and caching.
5. **Safety limits** Max 50 files, 100KB per file to prevent issues with massive plugin directories.
6. **FileTree + FileViewer inline in SkillDetail** No need for separate components given the simplicity; keeps code collocated.
