+# Muyue PRD v1.0
+
+> **Author**: Product Architect  
+> **Date**: 2026-04-22  
+> **Status**: Definitive
+
+---
+
+## 1. Product Vision & Positioning
+
+### What is Muyue?
+
+Muyue is a local-first, single-binary development environment assistant that combines an AI orchestration layer, a tool manager, and a cyberpunk-themed desktop UI into one cohesive experience. It scans your system, installs missing tools, configures AI agent environments (MCP servers, LSPs, skills), and provides a Studio for AI-assisted workflows — all without requiring cloud infrastructure.
+
+### What problem does it solve?
+
+Developers spend significant time setting up and maintaining their dev environments: installing tools, configuring MCP servers for AI agents, managing API keys, and switching between CLI tools. Muyue eliminates this friction by providing a single interface that unifies environment management, AI orchestration, and terminal access. It is the "home base" for developers who use AI coding agents (Crush, Claude Code) daily.
+
+### Who is it for?
+
+- **Primary**: Solo developers and small teams who use AI coding agents (Crush, Claude Code) and want a unified control panel.
+- **Secondary**: Developers setting up new machines who want a "one-click" environment bootstrap.
+- **Not for**: Enterprise teams needing sandboxed environments (Daytona), container orchestration (DevPod), or MCP server registries (MCPM).
+
+### How is Muyue different?
+
+| Competitor | What they do | What Muyue does differently |
+|---|---|---|
+| **Daytona** | Cloud sandbox infrastructure for AI agents (sandboxes, snapshots, multi-tenant) | Muyue is local-first, lightweight, no infra required. Daytona is "cloud VMs for AI"; Muyue is "desktop control panel for your local AI agents". |
+| **kasetto** | Declarative AI agent environment manager (Rust, CLI-only) | Muyue adds a desktop GUI, interactive workflows, and a terminal. kasetto is "Nix for AI tools"; Muyue is "a cockpit". |
+| **OpenCode** | Terminal-based AI coding agent (Go, TUI, LSP+MCP client) | OpenCode is an AI coding agent itself. Muyue orchestrates agents (Crush, Claude) rather than being one. Muyue provides a desktop UI, tool management, and MCP config generation that OpenCode doesn't. |
+| **DevPod** | Dev environment manager using devcontainers (Go, CLI+Desktop) | DevPod manages remote/container environments. Muyue manages your local machine's tools and AI agent configs. No container overlap. |
+| **MCPM** | MCP server package manager (Python, CLI, registry) | Muyue generates MCP configs for Crush + Claude Code directly. Delegates server discovery to MCPM where needed. |
+| **McpMux** | Desktop MCP gateway/router (Rust) | Muyue manages MCP configs per-tool rather than routing through a gateway. Simpler, no encryption layer needed for local use. |
+
+### What Muyue should NOT do (anti-scope)
+
+1. **Not a coding agent** — Muyue orchestrates agents (Crush, Claude Code); it does not edit files, run tests, or write code autonomously. The `crush_run` tool delegates to Crush.
+2. **Not a sandbox/container manager** — No Docker orchestration, no VM provisioning. Use DevPod or Daytona for that.
+3. **Not an MCP registry** — No server discovery marketplace. Delegate to MCPM for that.
+4. **Not a CI/CD tool** — No build pipelines, no deployment workflows.
+5. **Not a multi-tenant platform** — Single-user, local machine only. No org management, no billing.
+6. **Not an IDE** — No file tree editor, no debugging, no syntax highlighting. Use VS Code, Zed, or Neovim.
+7. **Not an LSP client** — Muyue installs and manages LSP servers; it does not connect to them as a client. The IDE handles that.
+8. **Not a proxy/gateway** — No AI proxy agents, no request routing. The orchestrator talks directly to providers.

+
+### P0 — Needs Implementation/Completion
+
+| # | Feature | Priority | Status | Decision | Description |
+|---|---------|----------|--------|----------|-------------|
+| 22 | Dashboard tab (tools grid, notifications, quick actions) | P0 | **PARTIAL** | KEEP, BUILD | Currently shows empty workflow/activity placeholders. Needs: tools grid with status badges, update notifications, quick actions (install missing, check updates, rescan, configure MCP). |
+| 23 | Shell AI panel (real AI backend) | P0 | **EXISTS** | KEEP | Was fake, now uses `/api/shell/chat` with real AI backend + tool calling. Functional. |
+| 24 | Tool updates (check + auto-update) | P0 | **EXISTS** | KEEP | `internal/updater/` checks versions and runs auto-updates. API + CLI endpoints wired. |
+
+### P1 — Post-Launch
+
+| # | Feature | Priority | Status | Decision | Description |
+|---|---------|----------|--------|----------|-------------|
+| 25 | AI-generated skills (via Studio chat) | P1 | **STUBBED** | KEEP | `BuildAIGeneratePrompt()` exists but CLI `skills generate` is a stub. Need to wire to orchestrator. |
+| 26 | SSH test connectivity | P1 | **STUBBED** | KEEP | `handleSSHTest()` returns "not implemented". Add `net.DialTimeout` check. |
+| 27 | Conversation list/switch (multiple conversations) | P1 | **PARTIAL** | KEEP | `/api/conversations` list + delete exist. No create/switch/load. Need multi-conversation support in Studio. |
+| 28 | Dashboard activity log with real events | P1 | **MISSING** | KEEP | Wire install/scan/update events to a notification system that Dashboard renders. |
+| 29 | Starship prompt integration (multi-theme) | P1 | **EXISTS** | KEEP | 3 theme configs (charm, zerotwo, default). `handleApplyStarshipTheme` writes TOML + patches RC files. |
+| 30 | Terminal settings persistence (font, theme) | P1 | **EXISTS** | KEEP | Settings saved to config, loaded on startup. |
+
+### P2 — Nice-to-Have
+
+| # | Feature | Priority | Status | Decision | Description |
+|---|---------|----------|--------|----------|-------------|
+| 31 | Background daemon (`internal/daemon/`) | P2 | **MISSING** | DEFER | README mentions it. Not needed for launch. Tools can run on-demand. |
+| 32 | HTML preview server (`internal/preview/`) | P2 | **MISSING** | DROP | Use browser or IDE instead. Not Muyue's job. |
+| 33 | AI proxy agents (`internal/proxy/`) | P2 | **MISSING** | DROP | Direct provider communication is sufficient. No proxy layer needed. |
+
+### DROPPED
+
+| # | Feature | Reason | Replacement |
+|---|---------|--------|-------------|
+| 34 | HTML preview server | Not core value. IDEs handle this. | Browser / VS Code Live Preview |
+| 35 | AI proxy agents | Adds complexity without benefit for local-first tool. | Direct provider API calls |
+| 36 | MCP server registry / marketplace | Out of scope. | MCPM (`mcpm install <server>`) |
+| 37 | Sandboxed code execution | Out of scope. Requires infra. | Daytona sandboxes |
+| 38 | Dev container management | Out of scope. | DevPod |
+| 39 | Full IDE features (file tree, debugger) | Out of scope. | VS Code / Zed / Neovim |
+| 40 | LSP client mode (connecting to LSPs) | Out of scope. Muyue installs LSPs, doesn't consume them. | IDE handles LSP client |

+
+## 3. User Flows
+
+### 3.1 First-Time User Opens `muyue`
+
+```
+1. User runs `muyue` (or downloaded binary)
+2. No config exists → loadOrSetupConfig() detects first run
+3. Profiler TUI wizard launches:
+   a. Asks: name, pseudo, email
+   b. Scans system → detects languages → shows scored language options
+   c. Detects editors → shows scored editor options
+   d. Shows AI provider options → user picks one
+4. If selected provider has no API key → asks for key (masked input)
+5. Config saved to ~/.config/muyue/config.yaml (API key encrypted)
+6. Built-in skills installed to ~/.muyue/skills/
+7. MCP configs generated for Crush + Claude Code
+8. Desktop server starts on port 8080
+9. Browser opens to http://127.0.0.1:8080
+10. Onboarding wizard checks if profile is empty → shows web wizard as fallback
+11. Dashboard tab loads → shows tools grid (some installed, some missing)
+```
+
+**Edge cases:**
+- Config file exists but is corrupted → show error, offer `muyue setup` to recreate
+- No internet → profiler still works (local scan only), AI features unavailable
+- API key invalid → doctor command detects, Config tab shows "Invalid key" badge
+
+### 3.2 Returning User Opens `muyue`
+
+```
+1. User runs `muyue`
+2. Config exists → loads from ~/.config/muyue/config.yaml
+3. Desktop server starts → browser opens (or reconnects)
+4. Previous conversation loaded from conversation.json
+5. Dashboard shows current tool status (cached, 5-min TTL)
+6. If checkOnStart=true → background update check runs
+7. User picks up where they left off
+```
+
+### 3.3 User Installs a Missing Tool from Dashboard
+
+```
+1. Dashboard shows tools grid with status badges:
+   - Green ✓ = installed
+   - Red ✗ = missing
+   - Yellow ⟳ = update available
+2. User clicks "Install" on a missing tool (e.g., "pnpm")
+3. Frontend calls POST /api/install {"tools": ["pnpm"]}
+4. Backend spawns installer.InstallTool("pnpm") in goroutine
+5. Installer checks if already installed → if yes, returns success
+6. Installer runs `npm install -g pnpm`
+7. Result returned: {"status": "done", "tools": ["pnpm"], "results": [{...}]}
+8. Frontend updates tool status badge to green ✓
+9. Activity log entry added: "Installed pnpm"
+10. System scan cache invalidated
+```
+
+**Edge cases:**
+- Install fails (permission denied) → show error in results, suggest `sudo` or manual install
+- Tool requires Node.js but Node isn't installed → installer returns "npx not found, install node first"
+- Multiple tools installed in parallel → `sync.WaitGroup` handles concurrent installs
+
+### 3.4 User Starts a Chat in Studio
+
+```
+1. User clicks Studio tab (Ctrl+2)
+2. Chat history loaded from /api/chat/history
+3. If no history → welcome message shown
+4. User types message in textarea, presses Enter
+5. Frontend calls POST /api/chat {"message": "...", "stream": true}
+6. SSE connection opens
+7. Backend:
+   a. Adds message to conversation store
+   b. Checks if summarization needed (>80K tokens)
+   c. Creates orchestrator with active provider
+   d. Sets system prompt (Studio prompt with agent context)
+   e. Sets tools (all 10 agent tools as OpenAI function specs)
+   f. Sends to AI provider API
+8. Streaming begins:
+   a. Content chunks → SSE {"content": "char"} events
+   b. Tool calls → SSE {"tool_call": {...}} events
+   c. Tool results → SSE {"tool_result": {...}} events
+   d. Max 15 tool iterations
+9. Frontend renders:
+   a. Text content streamed character-by-character
+   b. Tool calls shown as expandable blocks with icon + status
+   c. Thinking blocks (if any) shown with spinner
+10. Final response stored in conversation
+11. SSE {"done": "true"} closes stream
+```
+
+**Edge cases:**
+- AI provider returns error → SSE error event, shown as red message
+- Tool execution times out → error result returned to AI, may retry
+- No active provider configured → 503 error, redirect to Config tab
+- API key invalid → 401 error, show "Configure your API key" prompt
+
+### 3.5 User Runs a Plan→Execute Workflow
+
+```
+1. User types `/plan Set up a Go project with Docker` in Studio
+2. Frontend calls POST /api/workflow/plan {"goal": "Set up a Go project..."}
+3. Backend:
+   a. Creates Planner with AI orchestrator
+   b. Sends goal to AI with planning prompt
+   c. AI generates JSON array of steps
+   d. Planner parses response into []Step
+   e. Workflow Engine creates workflow with steps
+4. Workflow returned to frontend with ID and steps
+5. Frontend shows workflow panel:
+   - Step 1: "Check Go installation" → tool: terminal, args: {command: "go version"}
+   - Step 2: "Create project directory" → tool: terminal, args: {command: "mkdir -p ..."}
+   - Step 3: "Initialize Go module" → tool: terminal, args: {command: "go mod init ..."}
+   - etc.
+6. User clicks "Execute"
+7. Frontend calls POST /api/workflow/execute/{id}?stream=true
+8. SSE stream:
+   a. Each step: {"event": "started", "step": {...}}
+   b. On completion: {"event": "done", "step": {...}}
+   c. On failure: {"event": "failed", "step": {...}}
+   d. If approval step: {"event": "awaiting_approval", "step": {...}}
+9. User can approve/skip steps via POST /api/workflow/approve/{id}
+10. Final event: {"event": "workflow_done", "status": "done|failed"}
+```
+
+**Edge cases:**
+- AI generates invalid JSON → planner returns error, shown in chat
+- Step fails mid-workflow → remaining steps skipped, workflow marked "failed"
+- Approval step → execution pauses until user approves
+- Workflow exceeds 10 steps → planner prompt limits to 10
+
+### 3.6 User Opens Shell, Connects via SSH
+
+```
+1. User clicks Shell tab (Ctrl+3)
+2. Default "Local Shell" tab created with xterm.js terminal
+3. WebSocket connects to /api/ws/terminal with {type: "shell", data: ""}
+4. Backend creates PTY via creack/pty, pipes I/O through WebSocket
+5. User sees their shell prompt (starship if configured)
+6. To add SSH tab:
+   a. User clicks "+" → dropdown shows:
+      - System terminals (zsh, bash, fish)
+      - Saved SSH connections (from config)
+      - "Add SSH connection" button
+   b. User selects saved connection or adds new one
+   c. New tab created with {type: "ssh", data: JSON.stringify({host, port, user, key_path})}
+   d. Backend establishes SSH connection, creates PTY
+   e. Tab shows connected indicator (green dot)
+7. User can rename tabs (double-click), close tabs (×), switch with Alt+1-7
+8. AI assistant panel on right:
+   a. User types question
+   b. Frontend calls POST /api/shell/chat with message + terminal context
+   c. AI responds with shell-aware answers (commands, explanations)
+   d. Can execute tools (terminal, read_file, etc.) to help user
+```
+
+**Edge cases:**
+- SSH connection fails → tab shows "Connection error" in terminal
+- WebSocket disconnects → terminal shows "Connection closed" message
+- Tab limit (7) reached → "+" button disabled
+- SSH key not found → connection fails, suggest key path
+
+### 3.7 User Changes AI Provider
+
+```
+1. User clicks Config tab (Ctrl+4)
+2. "AI Providers" panel shows list of providers:
+   - MiniMax (active) — Key configured ✓
+   - Z.AI — No key
+   - Anthropic — No key
+   - OpenAI — No key
+   - Ollama — No key (local)
+3. User clicks "Configure" on Anthropic
+4. Modal opens with fields: API Key, Model, Base URL
+5. User enters API key
+6. User clicks "Validate" → POST /api/providers/validate
+7. Backend sends test request to Anthropic API with key
+8. Response: {"status": "valid"} or error
+9. User clicks "Activate" → provider set active, others deactivated
+10. Config saved → new orchestrator instances use Anthropic
+```
+
+**Edge cases:**
+- Key validation fails → show "Invalid key" badge, don't save
+- No internet → validation times out, show "Connection failed"
+- Ollama selected but not running → user sees local URL, no validation needed
+- Switching provider mid-conversation → new messages use new provider, old messages preserved
+
+### 3.8 User Manages MCP Servers
+
+```
+1. User opens Config tab → MCP section
+   OR: User runs `muyue mcp scan` from CLI
+2. System scans 12 known MCP servers (filesystem, github, git, fetch, memory, etc.)
+3. Each server shows: name, category, installed status (npx available)
+4. User clicks "Configure MCP" → POST /api/mcp/configure
+5. Backend:
+   a. Generates MCP config for Crush: ~/.config/crush/crush.json → {"mcps": {...}}
+   b. Generates MCP config for Claude Code: ~/.claude.json → {"mcpServers": {...}}
+   c. Core servers: filesystem, fetch, memory
+   d. Provider-specific: minimax-web-search, minimax-image (if API key set)
+   e. Claude-specific: sequential-thinking
+6. Configs written with 0600 permissions
+```
+
+**Edge cases:**
+- Existing configs not overwritten (merged) — `writeMCPConfig` merges into existing JSON
+- No API key for provider-specific servers → those servers omitted
+- Crush or Claude Code not installed → configs still generated (for when they are installed)
+
+### 3.9 User Manages LSP Servers
+
+```
+1. User runs `muyue lsp scan` from CLI
+   OR: views LSP section in Config tab
+2. System checks 16 known LSP servers
+3. Each shows: name, language, command path, installed status
+4. User installs specific LSP:
+   - CLI: `muyue lsp install gopls`
+   - API: POST /api/lsp/install {"name": "gopls"}
+5. Backend runs install command (e.g., `go install golang.org/x/tools/gopls@latest`)
+6. Result: success or error
+```
+
+**Edge cases:**
+- LSP has no auto-install command (e.g., clangd) → return "install manually" message
+- Install fails (network error) → show error, suggest retry
+- Language mapping: TypeScript installs 4 servers (TS, JSON, HTML, CSS)
+
+### 3.10 User Creates/Deploys a Skill
+
+```
+1. User runs `muyue skills init` → installs 5 built-in skills to ~/.muyue/skills/
+2. User creates custom skill:
+   - Manually: create ~/.muyue/skills/my-skill/SKILL.md with YAML frontmatter
+   - CLI: `muyue skills generate my-skill "Does X for Y" crush`
+   - API: POST /api/skills (via Config tab or Studio chat)
+3. SKILL.md format:
+   ```yaml
+   ---
+   name: my-skill
+   description: What it does
+   author: username
+   version: 1.0.0
+   target: crush|claude|both
+   tags: [tag1, tag2]
+   ---
+   # Skill instructions in markdown
+   ```
+4. Deploy: `muyue skills deploy`
+5. Skill copied to:
+   - Crush: ~/.config/crush/skills/my-skill/SKILL.md
+   - Claude Code: ~/.claude/skills/my-skill/SKILL.md
+```
+
+**Edge cases:**
+- Skill already exists at target → overwritten
+- Target is "both" → deployed to both Crush and Claude
+- Delete removes from all locations (source + targets)
+
+### 3.11 User Runs `muyue scan` from CLI
+
+```
+1. User runs `muyue scan`
+2. Scanner runs full system scan (tools, runtimes, shell, git)
+3. Output: formatted table with columns: Tool, Version, Status, Path
+4. Summary line: "Installed: 8/14"
+5. With --json flag: full JSON output
+```
+
+### 3.12 User Runs `muyue doctor` from CLI
+
+```
+1. User runs `muyue doctor`
+2. Three checks run:
+   a. System scan → shows installed/missing tools
+   b. Config check → loads config, validates profile
+   c. Connectivity check → HEAD requests to AI provider endpoints
+3. Output: diagnostic report with ✓/✗ indicators
+4. User sees what's broken and can take action
+```

+
+## 7. Technical Decisions
+
+### 7.1 CLI Framework: **Keep Cobra** ✓
+
+**Decision**: Keep `spf13/cobra` (already in `go.mod`, already used for all 11 subcommands).
+
+**Rationale**: Cobra is the de-facto standard for Go CLIs. All commands are already implemented. No benefit to switching to `urfave/cli`.
+
+### 7.2 HTTP Router: **Keep stdlib `http.ServeMux`** ✓
+
+**Decision**: Keep `net/http.ServeMux`. Do NOT add chi, echo, or gin.
+
+**Rationale**: 
+- 37 routes registered. Stdlib handles this fine.
+- Go 1.22+ `ServeMux` supports method-based routing (`GET /api/foo`).
+- Adding a framework adds a dependency and learning curve for no benefit.
+- Performance is irrelevant at localhost scale.
+
+**One improvement**: Use Go 1.22 method-based patterns to clean up manual method checks:
+```go
+mux.HandleFunc("GET /api/tools", s.handleTools)
+mux.HandleFunc("POST /api/install", s.handleInstall)
+```
+
+### 7.3 WebSocket: **Keep gorilla/websocket** ✓
+
+**Decision**: Keep `gorilla/websocket` for terminal PTY.
+
+**Rationale**: Already working for terminal WebSocket. Only used for one endpoint (`/api/ws/terminal`). No need for a framework.
+
+### 7.4 Frontend Framework: **Keep vanilla React** ✓
+
+**Decision**: Keep React 19 + vanilla state management. Do NOT add zustand or react-query.
+
+**Rationale**:
+- 4 components, ~1200 lines total. State is simple (tab switching, form inputs, chat messages).
+- Adding zustand/redux would be over-engineering for this scale.
+- `useState` + `useCallback` + `useRef` is sufficient.
+- SSE handling is custom and wouldn't benefit from react-query.
+
+**One consideration**: If Dashboard grows complex (many sub-components), extract a `useApi` custom hook pattern for data fetching.
+
+### 7.5 Async Operations: **SSE for everything** ✓
+
+**Decision**: Use SSE (Server-Sent Events) for all streaming operations (chat, workflow execution). Use synchronous JSON for non-streaming operations (install, scan).
+
+**Rationale**:
+- SSE is already implemented for chat and workflow execution.
+- Install operations are fast enough to be synchronous (wait for all goroutines, return results).
+- No polling needed.
+- WebSocket only for terminal PTY (bidirectional needed).
+
+### 7.6 Workflow Engine: **State machine** ✓
+
+**Decision**: Keep the current state machine approach. Do NOT convert to a DAG.
+
+**Rationale**:
+- Plans are linear sequences (step 1 → step 2 → step 3).
+- Dependencies are simple (wait for previous step).
+- DAG adds complexity (topological sort, parallel execution) for no benefit.
+- The current `depends_on` field supports basic ordering. Parallel execution can be added later if needed via `TypeParallel` step type (already defined but not implemented).
+
+### 7.7 Styling: **Keep CSS custom properties** ✓
+
+**Decision**: Keep CSS custom properties + 4 theme objects. Do NOT add Tailwind or CSS-in-JS.
+
+**Rationale**:
+- 30+ CSS variables already define the full theme system.
+- Theme switching works by setting `document.documentElement.style.setProperty()`.
+- Adding Tailwind would conflict with the existing CSS architecture.
+- Current CSS is ~1000 lines and well-structured.

+
+## 8. Delegation Strategy
+
+### What Muyue delegates to existing tools
+
+| Feature | Delegated To | Integration Method | UI |
+|---------|-------------|-------------------|-----|
+| **Code editing / AI coding** | Crush (`crush run`) | `crush_run` agent tool → spawns `crush run <task>` | Studio chat invokes tool, Shell AI panel invokes tool |
+| **Code editing / AI coding** | Claude Code | Skills deployed to `~/.claude/skills/` | Config tab shows deployment status |
+| **MCP server discovery** | MCPM (`mcpm`) | CLI passthrough suggestion | Doctor command suggests `mcpm install <server>` if server missing |
+| **MCP server routing** | McpMux | Not needed | Muyue generates per-tool configs directly |
+| **Dev environments / containers** | DevPod | CLI passthrough suggestion | Doctor suggests DevPod if container needed |
+| **IDE features** | VS Code / Zed / Neovim | Config integration (editor preference) | Config tab sets editor, LSPs installed for editor |
+| **Terminal prompt** | Starship | Config generation (`starship.toml` + RC file patching) | Config tab applies themes |
+| **Git operations** | `git` CLI | Agent `terminal` tool runs git commands | Studio / Shell AI can execute git commands |
+
+### Integration Patterns
+
+1. **Config Generation** (primary pattern): Muyue generates config files for external tools (Crush `crush.json`, Claude `.claude.json`, Starship `starship.toml`). This is the cleanest integration — no API coupling, no version lock-in.
+
+2. **CLI Wrapping**: Muyue invokes external CLIs (`crush run`, `git`, `go install`) through the agent `terminal` tool. Stdout/stderr captured and returned to AI.
+
+3. **Suggestion**: Muyue suggests tools the user should install separately (MCPM, DevPod) but doesn't wrap them. `muyue doctor` output includes recommendations.
+
+4. **Skills Deployment**: Muyue's skills system deploys SKILL.md files to both Crush and Claude Code directories. Both tools natively understand this format.
+
+---
+
+## 9. Implementation Priority
+
+### Phase 1: Dashboard Completion (P0 gap)
+
+The only significant P0 gap is the Dashboard. Current state: empty placeholders.
+
+**Dashboard must have:**
+1. **Tools Grid** — Cards for each scanned tool showing name, status badge (installed/missing/update), version, install button
+2. **Quick Actions** — Buttons: "Install missing tools", "Check for updates", "Rescan system", "Configure MCP"
+3. **Update Notifications** — List of tools with available updates, with "Update" buttons
+4. **Activity Log** — Scrollable list of recent events (installs, scans, config changes) with timestamps
+
+**Implementation approach:**
+- Fetch from `/api/tools`, `/api/updates`, `/api/editors` on mount
+- Quick actions call existing API endpoints (`POST /api/install`, `POST /api/scan`, `POST /api/mcp/configure`)
+- Activity log: client-side event accumulation (no backend change needed for MVP)
+
+### Phase 2: CLI Polish (P0 gaps)
+
+1. Wire `muyue skills init` to `skills.InstallBuiltinSkills()`
+2. Wire `muyue skills generate` to orchestrator
+3. Register `muyue config get` and `muyue config set` subcommands
+4. Pass loaded config to installer in `muyue install`
+
+### Phase 3: P1 Features
+
+1. AI-generated skills via Studio chat
+2. SSH connectivity test
+3. Multi-conversation support in Studio
+4. Real event-based activity log
+

+## 11. Risks & Mitigations
+
+| Risk | Impact | Mitigation |
+|------|--------|-----------|
+| AI provider API changes break orchestrator | Studio/Shell chat stops working | Orchestrator uses OpenAI-compatible format (widely supported). Fallback: user switches provider. |
+| Tool install commands change (brew, apt) | Installer fails | Installer returns clear error messages. Doctor command diagnoses. User can install manually. |
+| Frontend grows beyond vanilla React manageability | Hard to maintain | At current scale (4 components), this is not a risk. Re-evaluate if components exceed 20. |
+| Security: API keys in config file | Key exposure | AES-256-GCM encryption at rest. Config file permissions 0600. |
+| Terminal WebSocket security | Remote command execution | Server binds to 127.0.0.1 only. No remote access possible. |

+Tu es l'assistant IA de **Muyue Studio**, le centre de commandement de l'environnement de développement de l'utilisateur.
+
+Tu es intégré dans Muyue, un gestionnaire d'environnement de développement de bureau. Ton rôle est d'aider l'utilisateur à configurer, gérer et optimiser son environnement dev.
+
+## Environnement
+
+Muyue gère :
+- **Fournisseurs IA** (OpenAI, Anthropic, Ollama, MiniMax, etc.)
+- **Outils de développement** (Crush, Claude Code, etc.)
+- **Terminaux locaux et SSH**
+- **Configuration et préférences**
+- **Serveurs MCP et LSP**
+
+## Outils disponibles
+
+Tu as accès à des outils. Utilise-les concrètement, ne décris pas ce que tu ferais — fais-le.
+
+- **terminal** : Exécuter des commandes shell (builds, tests, git, etc.)
+- **crush_run** : Déléguer une tâche complexe à l'agent Crush (édition de fichiers, refactoring, debug)
+- **read_file** : Lire le contenu d'un fichier
+- **list_files** : Lister les fichiers d'un répertoire
+- **search_files** : Chercher des fichiers par motif (glob)
+- **grep_content** : Chercher du texte dans le contenu des fichiers
+- **get_config** : Lire la configuration Muyue
+- **set_provider** : Configurer un fournisseur IA
+- **manage_ssh** : Gérer les connexions SSH
+- **web_fetch** : Récupérer le contenu d'une URL
+
+## Règles
+
+1. **AGIS, ne décris pas** — Si l'utilisateur demande de faire quelque chose, utilise les outils pour le faire. Ne dis pas "je pourrais faire X" — fais-le.
+2. **Sois concis** — Pas de préambule, pas de blabla. Réponse directe.
+3. **Une chose à la fois** — N'appelle pas plusieurs outils simultanément sauf si c'est nécessaire.
+4. **Gère les erreurs** — Si un outil échoue, essaie une approche différente avant de le dire à l'utilisateur.
+5. **Ne devine pas** — Si tu n'as pas assez d'informations, utilise les outils pour les obtenir (lire un fichier, chercher, etc.)
+6. **Confidentialité** — Ne révèle jamais les clés API, mots de passe ou informations sensibles dans tes réponses.
+7. **Langue** — Réponds dans la même langue que l'utilisateur.
+
+## Format des réponses
+
+- Code : utilise des blocs markdown
+- Résultats d'outils : résume les points clés, ne colle pas des milliers de lignes
+- Erreurs : explique clairement et propose une solution
+- Succès : confirme brièvement ce qui a été fait

+Use this skill when the user needs Docker configuration for a project.
+
+## Dockerfile Best Practices
+
+1. Use multi-stage builds to reduce image size:
+   - Builder stage: install dependencies, compile
+   - Runtime stage: copy only the binary/artifacts
+
+2. Use specific base image tags (not ` + "`latest`" + `):
+   - ` + "`golang:1.24-alpine`" + ` for Go
+   - ` + "`node:22-slim`" + ` for Node.js
+   - ` + "`python:3.12-slim`" + ` for Python
+
+3. Order layers for cache efficiency:
+   - Copy dependency files first (go.mod, package.json, requirements.txt)
+   - Install dependencies
+   - Copy source code last
+
+4. Add health checks:
+   ` + "```" + `dockerfile
+   HEALTHCHECK --interval=30s --timeout=3s CMD curl -f http://localhost:8080/health || exit 1
+   ` + "```" + `
+
+5. Run as non-root user:
+   ` + "```" + `dockerfile
+   RUN adduser -D appuser
+   USER appuser
+   ` + "```" + `
+
+## docker-compose.yml Structure
+
+` + "```" + `yaml
+version: "3.9"
+services:
+  app:
+    build: .
+    ports:
+      - "8080:8080"

+
+## Audit Checklist
+
+### Input Validation (OWASP A03:2021)
+- All user input is validated and sanitized
+- SQL queries use parameterized statements
+- File paths are validated (no path traversal)
+- Input length limits are enforced
+
+### Authentication and Authorization (OWASP A07:2021)
+- Passwords are hashed with bcrypt/argon2 (never MD5/SHA1)
+- JWT tokens have short expiry with refresh rotation
+- Session management is secure
+- RBAC or ABAC is properly implemented
+- API endpoints have proper auth checks
+
+### Data Protection (OWASP A02:2021)
+- Secrets are not in source code (use env vars or secret managers)
+- Sensitive data is encrypted at rest and in transit
+- PII is properly handled and not logged
+- TLS is enforced for all connections
+
+### Dependency Security (OWASP A06:2021)
+- Run ` + "`npm audit`" + `, ` + "`pip audit`" + `, or ` + "`go vuln check`" + `
+- Check for known CVEs in dependencies
+- Keep dependencies up to date
+- Use lock files for reproducible builds
+
+### Configuration Security
+- Debug mode is disabled in production
+- CORS is properly configured
+- Rate limiting is in place
+- Security headers are set (CSP, HSTS, X-Frame-Options)
+- Error messages do not leak internal details
+
+## Automated Checks
+
+Run these tools if available:
+- ` + "`gosec ./...`" + ` for Go security
+- ` + "`bandit -r .`" + ` for Python security
+- ` + "`npm audit`" + ` for Node.js vulnerabilities
+- ` + "`trivy fs .`" + ` for container/Dockerfile scanning

+- **Windsurf**: ` + "`~/.windsurf/mcp.json`" + ` (key: ` + "`mcpServers`" + `)
+
+## Common MCP Servers
+
+| Server | Package | Required Env |
+|--------|---------|-------------|
+| filesystem | @modelcontextprotocol/server-filesystem | None |
+| fetch | @modelcontextprotocol/server-fetch | None |
+| github | @modelcontextprotocol/server-github | GITHUB_PERSONAL_ACCESS_TOKEN |
+| brave-search | @modelcontextprotocol/server-brave-search | BRAVE_API_KEY |
+| memory | @modelcontextprotocol/server-memory | None |
+| postgres | @modelcontextprotocol/server-postgres | DATABASE_URL |
+| sqlite | @modelcontextprotocol/server-sqlite | None |
+| docker | @modelcontextprotocol/server-docker | None |
+
+## Setup Steps
+
+1. Ask which editors the user wants to configure
+2. Ask which MCP servers they need
+3. For servers requiring API keys, prompt for the key
+4. Generate configs for each selected editor
+5. Validate configs (check JSON is valid, commands exist)
+6. Test connectivity if possible
+
+## Credential Management
+
+- API keys should be stored in the Muyue config (encrypted)
+- When generating MCP configs, inject keys from the Muyue config
+- Never hardcode API keys in config files in version control
+- Suggest adding MCP config files to ` + "`.gitignore`" + `
+
+## Troubleshooting
+
+- If npx fails, suggest ` + "`npm install -g`" + ` the package
+- If a server does not start, check the command and args
+- If auth fails, verify the API key is correct and active`,

+| Svelte | svelte-language-server | ` + "`npm install -g`" + ` |
+
+## Auto-Detection
+
+Detect project languages from:
+- Config files: ` + "`go.mod`" + `, ` + "`package.json`" + `, ` + "`Cargo.toml`" + `, ` + "`pyproject.toml`" + `
+- Source file extensions: ` + "`*.go`" + `, ` + "`*.py`" + `, ` + "`*.ts`" + `, ` + "`*.rs`" + `
+
+## Editor Config Generation
+
+### Neovim
+Generate ` + "`lspconfig`" + ` setup snippet for each LSP.
+
+### Helix
+Generate ` + "`languages.toml`" + ` entries with language-server mappings.
+
+### VS Code / Cursor
+Generate ` + "`extensions.json`" + ` recommendations for each LSP.
+
+## Health Checks
+
+After installation, verify:
+1. The binary is in PATH
+2. The version matches expected
+3. A basic ` + "`initialize`" + ` request succeeds (if applicable)`,

+- ` + "`pre-commit`" + `: lint, format check, trailing whitespace
+- ` + "`commit-msg`" + `: validate conventional commit format
+- ` + "`pre-push`" + `: run tests
+
+## Branch Protection Rules
+
+- Require PR reviews (at least 1 approval)
+- Require status checks to pass
+- Require up-to-date branch before merge
+- Require linear history (rebase merge)
+
+## Development Process
+
+1. Pick a task from the backlog
+2. Create a feature branch
+3. Implement with tests
+4. Run linter and tests locally
+5. Push and create PR
+6. Address review feedback
+7. Merge when approved and CI passes
+8. Delete feature branch
+
+## Error Handling
+
+- If CI fails, provide clear error output and suggested fixes
+- If hooks fail, explain what failed and how to fix
+- Suggest ` + "`--no-verify`" + ` only as a last resort, with a warning`,
