+## v0.7.7
+
+### Fix : install Windows échoue silencieusement quand une version précédente tourne
+
+Symptôme rapporté en mettant à jour de v0.7.5 → v0.7.6 : `Expand-Archive ... -Force` semble réussir mais le `.exe` n'est en réalité pas écrasé (Windows refuse de remplacer un fichier verrouillé), donc après l'install, `muyue` lance toujours l'ancienne version. Aucun message d'erreur visible — d'où le côté traître.
+
+**Fix** : ajout d'une 1ʳᵉ ligne au snippet d'install qui tue toute instance Muyue déjà lancée :
+
+```powershell
+Get-Process muyue, muyue-windows-amd64 -ErrorAction SilentlyContinue | Stop-Process -Force; Start-Sleep -Milliseconds 500
+```
+
+`-ErrorAction SilentlyContinue` rend l'étape idempotente (pas d'erreur si rien ne tourne, cas d'install propre). Le `Start-Sleep` 500ms laisse Windows libérer le file handle. Le snippet officiel passe à 6 lignes ; une note explicative est ajoutée dans la section *Install* du changelog généré.
+
+## v0.7.6
+
+### Trois fixes Windows + une amélioration agent
+
+#### Métriques dashboard à 0 sur Windows
+
+Symptôme : CPU / RAM / Réseau toujours à 0 dans le panneau Dashboard sous Windows. Cause : `handleSystemMetrics` lisait exclusivement `/proc/stat`, `/proc/meminfo`, `/proc/net/dev` — fichiers absents sur Windows, donc `os.ReadFile` échouait silencieusement et la struct restait à zéro.
+
+Split en fichiers `_unix.go` / `_windows.go` :
+- **`metrics_unix.go`** (`!windows`) : reprend tel quel le code `/proc/...` existant.
+- **`metrics_windows.go`** : appelle `kernel32!GetSystemTimes` (CPU, ratio idle/total entre deux samples) et `kernel32!GlobalMemoryStatusEx` (RAM totale + dispo). Pas de spawn PowerShell, ~50 µs par appel. Réseau à zéro pour l'instant — `MIB_IF_ROW2` est trop sensible aux versions de Windows pour faire ça à la main proprement (TODO à part).
+- `handleSystemMetrics` réduit à un appel à `collectSystemMetrics()`.
+
+#### Terminal écran noir sur Windows
+
+Symptôme : sous Windows native, le tab terminal ouvre la connexion mais l'écran reste noir, aucune sortie. Cause : `creack/pty/v2` retourne *"operating system not supported"* → fallback aux pipes. Pipes ne portent pas les signaux TTY, donc `cmd.exe` / `pwsh` / `wsl.exe` détectent l'absence de TTY et passent en mode silencieux ou attendent indéfiniment.
+
+Implémentation **ConPTY** native via `kernel32!CreatePseudoConsole` (`internal/api/terminal_conpty_windows.go`) :
+- Probe runtime `canUseConPTY()` (cache la disponibilité — Windows 10 1809+ requis).
+- Crée un pseudo-console + 2 pipes anonymes, les passe au child via `STARTUPINFOEX` + `PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE` (utilise `windows.NewProcThreadAttributeList`).
+- `CreateProcessW` lance le shell avec le PC attaché → ANSI / cursor / line discipline marchent comme sur un vrai TTY.
+- `ResizePseudoConsole` câblé sur les events de redimensionnement xterm.
+- Fallback `pipeSession` conservé si `canUseConPTY()` est false (Windows < 1809) ou si `startConptySession` échoue.
+- Restructure des fichiers : `terminal_session.go` (interface + structs), `terminal_session_unix.go` (creack/pty), `terminal_session_windows.go` (ConPTY → pipe fallback), `terminal_conpty_windows.go` (impl).
+
+#### Limite d'itérations d'outils agent
+
+Symptôme : *"l'IA semble s'arrêter après 15 exécutions d'outils, je veux qu'elle puisse en faire 100, voire 1000"*. Cause : `MaxToolIterations = 15` dans `chat_engine.go`.
+
+Bump : 15 → 500. Cap reste pour éviter les boucles infinies en cas de bug modèle, mais 500 itérations couvre largement les cas réels (refactor multi-fichiers, debug exploratoire). Documentation inline ajoutée pour expliquer pourquoi le cap existe et quand il faudrait s'inquiéter de le toucher.
+
+## v0.7.5
+
+### Fix Windows : commande `muyue` reconnue après install
+
+Symptôme rapporté : après les commandes d'install, `muyue` retourne `n'est pas reconnu comme nom d'applet de commande`. Causes :
+- Le binaire extrait s'appelle `muyue-windows-amd64.exe` — taper `muyue` ne résoud pas
+- La PATH utilisateur a été mise à jour mais la session PowerShell courante n'en hérite que pour les NOUVEAUX processus
+
+Corrections dans `install-shortcuts` :
+- **Copie canonique** : `muyue.exe` est créé à côté de `muyue-windows-amd64.exe` (copy, pas rename — le binaire en cours d'exécution est verrouillé sur Windows). Les raccourcis Bureau / Menu Démarrer ciblent désormais cette copie.
+- **Hint de session** : la commande imprime `$env:Path += ';...'` à coller pour activer `muyue` dans le shell courant sans rouvrir un terminal.
+
+Snippet d'install passe à 5 lignes : la dernière (`$env:Path += ";$dest"`) rend la commande dispo immédiatement dans la session.
+
+### Fix Windows : double-clic du raccourci fonctionne enfin
+
+Symptôme rapporté : après installation, double-clic sur le raccourci Bureau → boîte de dialogue *"This is a command line tool. You need to open cmd.exe and run it from there."*. Cause : `charmbracelet/huh` (utilisé pour la TUI de premier lancement) détecte l'absence de TTY interactif quand le binaire est lancé via Explorer Windows et avorte avec ce message.
+
+Double correctif :
+
+1. **Skip de la TUI sans terminal interactif** (`cmd/muyue/commands/root.go::isInteractiveStdin`) — si `os.Stdin.Stat()` indique pas de `os.ModeCharDevice`, on saute `profiler.RunFirstTimeSetup` et on persiste un `config.Default()`. L'onboarding web (déjà existant) prend ensuite le relais dès l'ouverture du navigateur — aucune régression : avec un vrai terminal, la TUI continue de tourner comme avant.
+
+2. **Build Windows en GUI subsystem** (`-H=windowsgui` ajouté aux Windows builds dans `ci-main.yml` et `ci-develop.yml`) — le binaire ne demande plus de console, donc plus aucun flash de fenêtre noire au double-clic.
+
+Conséquence : les sous-commandes CLI (`muyue scan`, `muyue version`, `muyue install-shortcuts`) ne produiraient plus d'output quand lancées depuis cmd.exe. Mitigation : nouveau fichier `cmd/muyue/console_windows.go` qui appelle `kernel32!AttachConsole(ATTACH_PARENT_PROCESS)` au démarrage. Si un terminal parent existe, on s'y rattache et `os.Stdout` / `os.Stderr` / `os.Stdin` y sont rebindés ; sinon, on tourne silencieusement (cas double-clic). Compatible des deux usages sans deux binaires séparés.
+
+## v0.7.4
+
+### Logo Muyue intégré
+
+- `LogoMuyue.png` ajouté à la racine + déclinaisons générées dans `assets/` (16/32/64/128/256/512 px) et `assets/muyue.ico` (multi-résolution 16-256 px).
+- **Binaire Windows** : icône embarquée comme ressource Windows via `github.com/akavel/rsrc` au build CI (génération de `cmd/muyue/rsrc_windows_{amd64,arm64}.syso`). Conséquences :
+  - Explorateur Windows affiche l'icône Muyue sur le `.exe`
+  - Les raccourcis créés par `install-shortcuts` héritent de l'icône (via `IconLocation = "$exe,0"`)
+  - Aucune dépendance Go à runtime ; les `.syso` sont gitignorés et regénérés à chaque build
+- **UI web** : favicon réel (16/32 px), apple-touch-icon (256 px) et logo affiché dans le header à côté de "MUYUE".
+- Snippet d'install Windows : 1ʳᵉ ligne idempotente (`New-Item -ItemType Directory -Force`) pour gérer le cas d'une ré-exécution après install partielle.
+- Préservation du logo source en pleine résolution (912×950 RGBA) — pas de perte d'information.
+
+## v0.7.3
+
+### Onboarding — focus MiniMax + MiMo
+
+- L'étape `apikey` du wizard de premier lancement propose désormais **les deux clés** (MiniMax + MiMo) côte à côte ; au moins une doit être validée pour continuer.
+- Les autres fournisseurs (OpenAI, Anthropic, Z.AI, Ollama) ne sont plus proposés dans le wizard — l'utilisateur les configure ensuite via l'onglet **Configuration** s'il le souhaite. Justification : pour les nouveaux utilisateurs, deux choix simples > six choix qui ralentissent le démarrage.
+- Si MiniMax est validé, il devient le provider actif. Sinon, c'est MiMo. Si les deux sont validés, MiniMax reste actif (peut être basculé via `/model change` plus tard).
+
+### Install Windows — pas d'admin + raccourcis automatiques
+
+- **Avant** : la 3ᵉ ligne du snippet d'install (`Move-Item ... C:\Windows\muyue.exe`) échouait avec `UnauthorizedAccessException` sur PowerShell sans élévation.
+- **Maintenant** : 4 lignes, toutes exécutables sans admin :
+  ```powershell
+  $dest = "$env:LOCALAPPDATA\Muyue"
+  Invoke-WebRequest -Uri ".../muyue-windows-amd64.zip" -OutFile "$env:TEMP\muyue.zip"
+  Expand-Archive -Path "$env:TEMP\muyue.zip" -DestinationPath $dest -Force
+  & "$dest\muyue-windows-amd64.exe" install-shortcuts
+  ```
+- Nouvelle commande `muyue install-shortcuts` (Windows uniquement) :
+  - crée `Muyue.lnk` sur le Bureau et dans le Menu Démarrer (résolus via `[Environment]::GetFolderPath`, robuste OneDrive / profils non-standards) ;
+  - utilise WScript.Shell COM via PowerShell pour générer les `.lnk` (pas de dépendance Go ajoutée) ;
+  - ajoute le dossier d'install au `PATH` utilisateur (scope User, pas de modif système).
+- Une icône custom pourra être branchée plus tard en remplaçant la ressource embed du `.exe` ; pour l'instant, l'icône Windows par défaut du binaire est utilisée.
+
+## v0.7.2
+
+### Amélioration
+
+- **feat(studio): réflexion avancée forcée automatiquement pendant les tests** — quand au moins une session `browser_test` est connectée, chaque message à Studio active automatiquement la réflexion avancée (un second modèle, si configuré, produit un rapport préalable injecté dans le prompt actif). Le toggle UI est ignoré tant qu'une session de test est active. Justification : pendant un test piloté par l'IA, avoir une analyse complémentaire d'un autre modèle améliore matériellement la qualité des décisions de clic et la couverture du rapport final.
+- Si aucun second provider n'est configuré, le comportement reste silencieux (fallback chat normal — pas d'erreur visible côté utilisateur).
+- Hint UI ajouté dans l'onglet Tests pour expliquer le comportement.
+
+## v0.7.1
+
+### Fix
+
+- **fix(terminal/windows): "unsupported" / connection closed** — `creack/pty` n'a pas de support Windows natif et `pty.Start()` retourne immédiatement une erreur ("operating system not supported"), fermant le WebSocket avant même la bannière. L'utilisateur voyait le menu des terminaux peuplé (détection OK : `wsl --list --quiet` fonctionne) mais chaque clic se soldait par "unsupported" ou une connexion fermée.
+- Introduction de l'abstraction `termSession` (`internal/api/terminal_session.go`) avec deux implémentations sélectionnées au runtime :
+  - **`ptySession`** (Linux / macOS / BSDs) : conserve le comportement existant (TTY complet via `creack/pty`, resize, apps interactives type vim/top).
+  - **`pipeSession`** (Windows) : pipes natifs `stdin` + `stdout` + `stderr` mergés, lus en goroutines, forwardés au WebSocket. Suffisant pour `wsl.exe`, `pwsh`, `cmd` en mode ligne — la plupart des cas d'usage (lancer une commande, voir la sortie, taper la suivante). Resize est un no-op (pas de SIGWINCH sans TTY) ; les TUIs en plein écran ne fonctionnent pas dans ce mode.
+- Refactor minimal de `handleTerminalWS` : utilise `startTermSession(cmd)` au lieu de `pty.Start(cmd)` direct ; même chemin code pour les deux OS.
+
+## v0.7.0
+
+### Changes since v0.4.0
+
+- fix(ci): rename browser_test.go → browsertest.go (6d2f174)
+- feat: AI-driven browser tests — Tests tab + browser_test agent tool (c820d55)
+- release: v0.6.0 — security audit fixes + 7 new features (6a7b4d8)
+- chore: bump version to 0.5.0 (2a6647b)
+- feat: agent concurrency, conversation summaries, AI tools config, UI polish (3740454)
+- feat: AI task API, token-based context windows, SSH password auth, sudo bypass detection (d98110c)
+- feat: agent concurrency, conversation summaries, AI tools config, UI polish (d2bb42b)

+## v0.7.0
+
+### Nouvelle fonctionnalité majeure : Tests pilotés par l'IA
+
+- **Onglet Tests** dédié dans l'UI : génère un snippet JS à coller dans n'importe quelle page web ouverte (Chrome, Firefox, Edge, dev local ou distant).
+- **Session WebSocket** authentifiée par token à usage unique (5 min TTL) — la page connectée transmet ses messages console en temps réel et expose une RPC pour cliquer / évaluer / inspecter.
+- **Outil agent `browser_test`** disponible pour Studio, avec actions :
+  - `list_clickables` : énumère tous les éléments cliquables visibles avec un index stable
+  - `click` : clic par sélecteur CSS ou par index — retourne le **delta console** émis pendant le clic
+  - `eval` : évalue une expression JS et retourne sa valeur sérialisée
+  - `console` / `summary` : lit le buffer console (200 dernières entrées)
+  - `current_url` : URL et titre courants
+  - `type` : remplit un champ input/textarea (utilise le setter natif pour compatibilité React)
+  - `wait` : pause asynchrone (max 5s)
+- **Stratégie BMAD** intégrée au prompt système Studio : boucle `summary → list_clickables → click → vérifier console_delta → rapport final ✓/✗/⚠`.
+- **Multi-sessions** : jusqu'à 16 onglets connectés simultanément ; éviction LRU au-delà.
+- **Sécurité** : token consommé à la première connexion ; CheckOrigin libre côté snippet (gating par token uniquement) ; CORS API REST inchangé.
+- **Backend** : `internal/api/browser_test.go` (nouveau, ~480 lignes) + 4 routes (`/api/test/snippet`, `/api/test/sessions`, `/api/test/console/{id}`, `/api/ws/browser-test`).
+- **Frontend** : `web/src/components/Tests.jsx` (nouveau) + nouvel onglet ⌃4.
+
+## v0.6.0
+
+### Audit & corrections (sécurité, concurrence, stabilité)
+
+- fix(api): empty `resp.Choices[0]` panic in chat engine — bounded check
+- fix(api): `defer release()` accumulating inside tool-call loop — release immediately after each tool call
+- fix(api): race in `ConversationStoreMulti.Add` (fire-and-forget save under released lock) — synchronous save under existing lock
+- fix(workflow): infinite busy-wait in `engine.Execute` when a dependency fails — propagate `StatusFailed`/`StatusSkipped` and short-circuit
+- fix(workflow): UTF-8-unsafe slicing of plan goal — rune-aware truncate
+- fix(security): CORS `Access-Control-Allow-Origin: *` — restricted to localhost origins
+- fix(security): API key disclosure in `/api/providers` — masked as `"***"`; saving handler ignores `"***"` placeholder
+- fix(security): SSH password disclosure in `/api/terminal/sessions` — masked; update handler preserves stored password if `"***"` is sent
+- fix(security): sshpass `-p` + `-e` mutually-exclusive flags — use only `-e` with `SSHPASS` env var
+- fix(security): unbounded chat request body — `MaxBytesReader` 50 MB
+- fix(security): unbounded image upload — 10 MB cap in `saveImage`
+- fix(security): font size unbounded — capped at 72
+- fix(security): `LSP /auto-install` accepted arbitrary `project_dir` — restricted to user home subtree
+- fix(api): silent `json.Unmarshal` errors in profile save — propagated
+- fix(ui): operator-precedence bug in `Shell.jsx` resize check — parenthesized
+
+### Nouvelles fonctionnalités
+
+- feat(ai): inject OS name (e.g. `Debian 12`, `Windows 11`, `macOS 14.5`) alongside date in Studio system prompt
+- feat(agents): default timeout raised to 30 minutes for `crush_run` and `claude_run`; max also 30 min
+- feat(agents): new optional params `cwd`, `wsl_distro`, `wsl_user` — agents can be launched in a specific directory, and on Windows hosts inside a specific WSL distribution under a specific user
+- feat(agents): new `claude_run` tool (mirrors `crush_run` for the Claude Code CLI)
+- feat(terminal): WSL distros listed individually as quick-launch entries in the new-tab menu (Windows hosts only)
+- feat(studio): system prompt rewritten around the BMAD-METHOD (Analyst/PM/Architect/SM/Dev/QA personas + mandatory `[OBJECTIF]/[CONTEXTE]/[CONTRAINTES]/[LIVRABLE]/[CRITÈRE D'ACCEPTATION]` template for any agent delegation)
+- feat(studio): "Réflexion avancée" toggle — when enabled, the inactive AI provider produces a preliminary report that is injected as `[RAPPORT PRÉALABLE]` context into the active provider's prompt
+- feat(studio): "Historique compressé" toggle — collapses past tool calls and keeps only the last visible action per assistant message, with `Tout afficher` to expand
+
+### Bug fix CI
+

+# 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.
+
+---
+
+## 2. Feature Matrix
+
+### P0 — Must Have for Launch
+
+| # | Feature | Priority | Status | Decision | Description |
+|---|---------|----------|--------|----------|-------------|
+| 1 | System scanning (tools, runtimes, editors, shell, git) | P0 | **EXISTS** | KEEP | Scanner checks 14 tools, 8 runtimes, 8 editors, shell setup, git config. Has 5-min cache, JSON output. |

+
+### 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>`) |

+
+## 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
+

+### Key Dependencies
+
+| Dependency | Version | Purpose |
+|-----------|---------|---------|
+| `spf13/cobra` | v1.10.2 | CLI framework |
+| `charmbracelet/huh` | v1.0.0 | TUI forms (profiler, API key input) |
+| `charmbracelet/bubbletea` | v1.3.10 | TUI framework (indirect) |
+| `gorilla/websocket` | v1.5.3 | Terminal WebSocket |
+| `creack/pty/v2` | v2.0.1 | PTY for terminal |
+| `gopkg.in/yaml.v3` | v3.0.1 | Config serialization |
+| React 19 | — | Frontend UI |
+| Vite 8 | — | Frontend build |
+| xterm.js | — | Terminal emulator component |
+
+### File Count Summary
+
+| Layer | Files | Lines (approx) |
+|-------|-------|---------------|
+| Go backend (`internal/`) | 41 `.go` files | ~8,000 |
+| CLI commands (`cmd/`) | 12 `.go` files | ~600 |
+| Frontend (`web/src/`) | ~20 files | ~3,500 |
+| CSS (`web/src/styles/`) | 1 file | ~1,500 |
+| **Total** | ~75 files | ~13,600 |
+
+---
+
+## 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, et tu es spécialisé dans la **construction de prompts** selon la **méthode BMAD** (Breakthrough Method for Agile AI-Driven Development — https://github.com/bmad-code-org/BMAD-METHOD).
+
+Tu es intégré dans Muyue, un gestionnaire d'environnement de développement de bureau. Ton rôle est double :
+1. Aider l'utilisateur à configurer, gérer et optimiser son environnement dev (avec les outils ci-dessous).
+2. Construire pour lui des prompts structurés et actionnables avant d'exécuter une tâche complexe ou de la déléguer à un agent (`crush_run`, `claude_run`).
+
+## Méthode BMAD — principes appliqués à chaque réponse
+
+BMAD organise le travail IA comme une équipe agile : chaque demande est traitée avec une persona spécifique (Analyst, PM, Architect, SM, Dev, QA) puis exécutée. Tu n'as pas besoin de jouer toutes les personas — applique simplement leurs réflexes :
+
+- **Analyst** : reformule l'objectif réel derrière la demande en 1 phrase. S'il est ambigu, choisis l'interprétation la plus probable et indique-la au début.
+- **PM** : découpe en livrables concrets (épopée → stories). Pas plus de 3-5 stories pour une demande, chaque story doit être indépendamment livrable.
+- **Architect** : pour toute story qui touche au code, identifie les fichiers concernés, les contraintes (compat, style, perf, sécurité) et les risques avant d'écrire.
+- **SM (Scrum Master)** : si tu délègues à `crush_run`/`claude_run`, fournis un prompt **autonome** : objectif, contraintes, fichiers cibles, critère d'acceptation. Pas de référence à la conversation parente — l'agent ne la voit pas.
+- **Dev** : exécute story par story. Vérifie chaque livraison avant de passer à la suivante.
+- **QA** : avant de répondre "fini", relis l'objectif initial et confirme qu'il est atteint.
+
+## Format d'un prompt BMAD délégué
+
+Quand tu construis un prompt pour `crush_run`/`claude_run`, suis ce gabarit :
+
+```
+[OBJECTIF] <une phrase, l'objectif final>
+[CONTEXTE] <fichiers/dossiers concernés, ce qui existe déjà>
+[CONTRAINTES] <ne pas faire X, préserver Y, respecter style Z>
+[LIVRABLE] <fichier(s) modifié(s), comportement attendu>
+[CRITÈRE D'ACCEPTATION] <comment savoir que c'est fini>
+```
+
+Ce gabarit est **obligatoire** pour toute délégation à un agent. Il évite que l'agent erre, suppose, ou produise du code hors-périmètre.
+
+<critical_rules>
+1. **AGIS, ne décris pas** — Si l'utilisateur demande de faire quelque chose, utilise les outils immédiatement. Ne dis pas "je pourrais faire X" — fais-le.
+2. **SOIS AUTONOME** — Ne pose pas de questions si tu peux chercher, lire, déduire. Essaie plusieurs approches avant de bloquer. Ne t'arrête que pour les erreurs bloquantes réelles (credentials manquants, permissions, etc.).
+3. **SOIS CONCIS** — Max 4 lignes par défaut. Pas de préambule ("Voici...", "Je vais..."), pas de postambule ("N'hésitez pas...", "J'espère que..."). Réponse directe. Un mot quand c'est suffisant.
+4. **GÈRE LES ERREURS** — Si un outil échoue, essaie 2-3 approches alternatives avant de rapporter l'échec. Lis le message d'erreur complet, isole la cause racine.
+5. **NE DEVINE PAS** — Lis les fichiers avant d'éditer. Utilise les outils pour obtenir les informations manquantes (lire, chercher, grep).
+6. **CONFIDENTIALITÉ** — Ne révèle jamais les clés API, mots de passe, tokens ou informations sensibles.
+7. **LANGUE** — Réponds dans la même langue que l'utilisateur.
+</critical_rules>
+
+## 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
+
+| Outil | Usage |
+|-------|-------|
+| **terminal** | Exécuter des commandes shell (builds, tests, git, etc.) |
+| **crush_run** | Déléguer une tâche complexe à Crush (édition de fichiers, refactoring, debug) — préfère cet outil pour les tâches multi-fichiers ou l'écriture de code |
+| **claude_run** | Déléguer une tâche complexe à Claude Code CLI |
+| **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 les 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 |
+| **browser_test** | Piloter un onglet de navigateur de l'utilisateur (clic, eval, lecture console) — voir `<browser_test_strategy>` ci-dessous |
+
+<browser_test_strategy>
+Quand l'utilisateur demande de **tester** une UI / une page (ses boutons, ses formulaires, son comportement), utilise `browser_test`. La page cible doit déjà être connectée via le snippet de l'onglet "Tests" — sinon, l'outil te le dira et tu demandes à l'utilisateur de coller le snippet.
+
+Boucle recommandée :
+
+1. `browser_test` action `summary` — voir l'URL, le titre et les dernières erreurs console déjà présentes.
+2. `browser_test` action `list_clickables` — récupérer la liste indexée des boutons / liens / inputs cliquables.
+3. Pour chaque cible : `browser_test` action `click` (avec `index` ou `selector`).
+4. Immédiatement après chaque clic, **regarde le `console_delta` retourné** : c'est la liste des messages console émis pendant le clic. `level: "error"` = bouton cassé.
+5. Vérifie aussi `current_url` retourné — un changement d'URL inattendu peut signaler un bug.
+6. Si l'élément ouvre un dialog ou modifie le DOM, refais `list_clickables` pour découvrir les nouveaux éléments.
+7. Pour les inputs : utilise `type` avant `click` sur le bouton de soumission.
+8. À la fin, fournis un **rapport** structuré : ✓ boutons OK / ✗ boutons cassés (avec le message d'erreur exact) / ⚠ boutons disabled ou non trouvés.
+
+Astuces :
+- Préfère cliquer **par `index`** que par sélecteur — le sélecteur change avec le DOM, l'index reste stable jusqu'au prochain `list_clickables`.
+- Entre deux actions sensibles, `wait` 200-500 ms si la page a des transitions / fetches asynchrones.
+- N'utilise jamais `eval` pour cliquer si `click` suffit.
+</browser_test_strategy>
+
+<tool_strategy>
+- **Recherche avant action** — Utilise `search_files`, `grep_content`, `read_file` avant de supposer quoi que ce soit sur l'état du système
+- **Délégation intelligente** — Pour les tâches complexes (refactoring, création de fichiers, debug multi-fichiers), utilise `crush_run` au lieu d'enchaîner des commandes terminal
+- **Lecture de fichiers** — Utilise TOUJOURS `read_file` pour lire le contenu d'un fichier. N'utilise PAS `terminal` avec `cat` pour lire des fichiers — `read_file` est plus rapide, plus précis, et consomme moins de tokens
+- **Parallélisme** — Lance plusieurs appels d'outils en parallèle quand les opérations sont indépendantes
+- **Troncature** — Si un résultat d'outil dépasse 2000 caractères, résume les points clés au lieu de tout afficher
+- **Une chose à la fois** — Sauf si les opérations sont indépendantes, exécute séquentiellement
+</tool_strategy>
+
+<decision_making>
+- Décide par toi-même : cherche, lis, déduis, agis
+- Ne demande confirmation que pour : actions destructrices (suppression, overwrite), plusieurs approches valides avec des trade-offs importants
+- Si bloqué : documente (a) ce que tu as essayé, (b) pourquoi tu es bloqué, (c) l'action minimale requise
+- Ne t'arrête jamais pour : tâche trop grosse (découpe), trop de fichiers (change-les), complexité (gère-la)
+</decision_making>
+
+<error_recovery>
+1. Lis le message d'erreur complet
+2. Comprends la cause racine
+3. Essaie une approche différente (pas la même)
+4. Cherche du code similaire qui fonctionne
+5. Applique un correctif ciblé
+6. Vérifie que ça marche
+7. Pour chaque erreur, essaie au moins 2-3 stratégies avant de conclure que c'est bloquant
+</error_recovery>
+
+## Format des réponses
+
+- **Code** : blocs markdown avec le langage spécifié
+- **Résultats d'outils** : résume les points clés, max 2000 caractères, ne copie pas des milliers de lignes
+- **Erreurs** : explique clairement la cause et propose une solution concrète
+- **Succès** : confirme brièvement ce qui a été fait (1 ligne)
+- **Multi-fichiers** : liste les fichiers modifiés avec `fichier:ligne` pour les références
+
+## Diagrammes Mermaid
+
+Tu peux utiliser des diagrammes Mermaid pour visualiser des architectures, flux, séquences, etc.
+Utilise un bloc code avec le langage `mermaid` :
+
+```mermaid
+graph TD
+    A[Début] --> B{Décision}
+    B -->|Oui| C[Action]
+    B -->|Non| D[Fin]
+```
+
+Types utiles :
+- `graph TD/LR` — Architecture, flux de données
+- `sequenceDiagram` — Interactions entre composants
+- `flowchart` — Processus et décisions
+- `classDiagram` — Structures de données
+- `erDiagram` — Schémas de base de données
+- `gantt` — Planning et timelines
+
+Utilise Mermaid quand ça apporte de la clarté : architecture complexe, flux multi-étapes, relations entre entités. Ne l'utilise pas pour du texte simple.

+1. **AGIS, ne décris pas** — Utilise l'outil terminal pour exécuter, ne te contente pas de proposer des commandes.
+2. **SOIS AUTONOME** — Cherche les infos manquantes via des commandes avant de demander à l'utilisateur. Essaie plusieurs approches avant de bloquer.
+3. **SOIS CONCIS** — Max 4 lignes par défaut. Pas de préambule. Réponse directe et technique.
+4. **GÈRE LES ERREURS** — Si une commande échoue, lis l'erreur, comprends la cause, essaie une approche alternative. 2-3 tentatives avant de rapporter.
+5. **SÉCURITÉ** — Ne révèle jamais de credentials. Demande confirmation avant les commandes destructrices (rm -rf, format, etc.).
+6. **LANGUE** — Réponds dans la même langue que l'utilisateur.
+</critical_rules>
+
+<tool_usage>
+Outil disponible : **terminal** — Exécute des commandes shell sur le système local.
+
+Stratégies :
+- **Diagnostique** — Enchaîne les commandes de diagnostic (ps, df, free, top, journalctl, dmesg, netstat, ss, etc.)
+- **Parallélisme** — Combine les commandes avec && ou ; quand elles sont indépendantes
+- **Filtrage** — Utilise grep, awk, sort, head pour extraire l'essentiel des sorties volumineuses
+- **Non-interactif** — Préfère les commandes non-interactives (apt install -y, non pas apt install)
+- **Troncature** — Si le résultat dépasse 2000 caractères, résume les points clés au lieu de tout afficher
+</tool_usage>
+
+<decision_making>
+- Décide par toi-même : exécute des commandes pour comprendre l'état du système
+- Ne demande confirmation que pour les actions destructrices
+- Si tu ne connais pas la commande exacte, exécute la commande avec --help pour la trouver
+- Si bloqué : documente ce que tu as essayé, pourquoi, et l'action minimale requise
+- Ne t'arrête jamais pour une tâche complexe — découpe en étapes et exécute-les
+</decision_making>
+
+<error_recovery>
+1. Lis le message d'erreur complet (stderr + stdout)
+2. Identifie la cause racine (permissions, paquet manquant, config, service)
+3. Essaie : vérifier le service, vérifier les logs, chercher le paquet, tester la connexion
+4. Propose une solution concrète, pas générique
+</error_recovery>
+
+<response_format>
+- **Commandes** : blocs markdown avec le langage (bash, sh, etc.)
+- **Résultats** : résume les métriques clés, pas de dump complet
+- **Erreurs** : cause + solution en 1-2 lignes
+- **Succès** : confirmation en 1 ligne
+- **Analyses** : markdown structuré avec sections si nécessaire
+</response_format>
+
+<mermaid>
+Tu peux utiliser des diagrammes Mermaid pour visualiser :
+- Architecture système (graph TD/LR)
+- Flux réseau (sequenceDiagram)
+- Processus (flowchart)
+- Timeline (gantt)

+Utilise un bloc de code avec le langage mermaid quand ça clarifie l'explication. Pas pour du texte simple.

+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:

+## 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

+
+## 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`,
