chore(release): v1.32.0

* feat(providers): surface skills in slash command menu

Provider skills were hidden behind provider-specific filesystem rules.

That made the backend and UI unable to offer one discovery path for skills.

Add a normalized skills contract, provider service, and provider skills API.

Keep provider-specific lookup rules inside adapters so routes and UI stay generic.

Claude needs plugin handling because enabled plugins resolve through installed_plugins.json.

Plugin folders can expose commands or skills, so Claude scans both forms.

Claude plugin commands are namespaced to avoid collisions with user and project skills.

Codex, Gemini, and Cursor adapters map their expected skill roots into the same contract.

The slash menu now shows skills beside built-in and custom commands for discovery.

The menu avoids mid-message activation, duplicate rows, loose namespace matches, and input overlap.

Provider tests cover discovery locations and Claude plugin edge cases.

* fix(providers): guard invalid skill command namespaces

Claude plugin ids come from local settings and installed plugin metadata.

Invalid ids such as empty strings or @ should not become command namespaces.

Skip plugin folders when no safe plugin name can be derived.

This prevents malformed slash commands like /:command from reaching the UI.

Add regression coverage for empty and @ plugin ids.

Keyboard selection in the slash menu should match mouse selection.

Only skills are inserted into the composer because they are provider invocations.

Built-in and custom commands execute directly and close the menu on success or failure.

* fix(security): centralize safe frontmatter parsing

Move frontmatter parsing into server/shared/frontmatter.ts so every backend caller
uses the same gray-matter configuration instead of importing gray-matter directly.

The goal is to keep executable JS and JSON frontmatter engines disabled for
all markdown discovered from the filesystem, not only command routes.

Provider skills and shared skill metadata now go through parseFrontMatter too.
That closes the gap where plugin or provider markdown could regain default
gray-matter behavior simply because it lived outside the original command path.

Classify the new parser in backend boundaries so modules can depend on the
safe shared API without reaching into legacy utility paths.

* feat(providers): add comprehensive guide for provider module setup and usage

+
+
+## Hızlı Başlangıç
+
+### CloudCLI Cloud (Önerilen)
+
+Başlamanın en hızlı yolu — yerel kurulum yok. Web, mobil uygulama, API veya favori IDE'nden erişilebilen, tam yönetilen, konteyner tabanlı bir geliştirme ortamına sahip ol.
+
+**[CloudCLI Cloud ile başla](https://cloudcli.ai)**
+
+
+### Kendin Barındır (Açık Kaynak)
+
+#### npm
+
+CloudCLI UI'yi **npx** ile anında dene (**Node.js** v22+ gerekir):
+
+```
+npx @cloudcli-ai/cloudcli
+```
+
+Veya düzenli kullanım için **genel olarak** kur:
+
+```
+npm install -g @cloudcli-ai/cloudcli
+cloudcli
+```
+
+`http://localhost:3001` adresini aç — mevcut tüm oturumların otomatik olarak keşfedilir.
+
+Tam yapılandırma seçenekleri, PM2, uzak sunucu kurulumu ve daha fazlası için **[dokümantasyonu ziyaret et →](https://cloudcli.ai/docs)**.
+
+#### Docker Sandbox'lar (Deneysel)
+
+Ajanları hipervizör seviyesinde izolasyonlu sandbox'larda çalıştır. Varsayılan olarak Claude Code başlar. [`sbx` CLI](https://docs.docker.com/ai/sandboxes/get-started/) gerekir.
+
+```
+npx @cloudcli-ai/cloudcli@latest sandbox ~/my-project
+```
+
+Claude Code, Codex ve Gemini CLI destekler. Kurulum ve gelişmiş seçenekler için [sandbox dokümantasyonuna](docker/) bak.

+CloudCLI UI, CloudCLI Cloud'u güçlendiren açık kaynak arayüz katmanıdır. Kendi makinende barındırabilir, izolasyon için Docker sandbox'ta çalıştırabilir veya tam yönetilen ortam için CloudCLI Cloud kullanabilirsin.
+
+| | Kendin Barındır (npm) | Kendin Barındır (Docker Sandbox) *(Deneysel)* | CloudCLI Cloud |
+|---|---|---|---|
+| **En iyi şunun için** | Kendi makinende yerel ajan oturumları | Web/mobil IDE ile izole ajanlar | Ajanlarını bulutta isteyen ekipler |
+| **Nasıl erişilir** | `[yourip]:port` üzerinden tarayıcıda | `localhost:port` üzerinden tarayıcıda | Tarayıcı, herhangi bir IDE, REST API, n8n |
+| **Kurulum** | `npx @cloudcli-ai/cloudcli` | `npx @cloudcli-ai/cloudcli@latest sandbox ~/project` | Kurulum gerekmez |
+| **İzolasyon** | Kendi host'unda çalışır | Hipervizör seviyesi sandbox (microVM) | Tam bulut izolasyonu |
+| **Makinenin açık kalması gerek** | Evet | Evet | Hayır |
+| **Mobil erişim** | Ağındaki herhangi bir tarayıcı | Ağındaki herhangi bir tarayıcı | Herhangi bir cihaz, native uygulama yolda |
+| **Desteklenen ajanlar** | Claude Code, Cursor CLI, Codex, Gemini CLI | Claude Code, Codex, Gemini CLI | Claude Code, Cursor CLI, Codex, Gemini CLI |
+| **Dosya gezgini ve Git** | Evet | Evet | Evet |
+| **MCP yapılandırması** | `~/.claude` ile senkron | UI üzerinden yönetilir | UI üzerinden yönetilir |
+| **REST API** | Evet | Evet | Evet |
+| **Ekip paylaşımı** | Hayır | Hayır | Evet |
+| **Platform maliyeti** | Ücretsiz, açık kaynak | Ücretsiz, açık kaynak | Aylık 7 $'dan başlar |
+
+> Tüm seçenekler kendi AI aboneliklerini (Claude, Cursor, vb.) kullanır — CloudCLI AI'ı değil, ortamı sağlar.

+## Güvenlik ve Araç Yapılandırması
+
+**🔒 Önemli Uyarı**: Tüm Claude Code araçları **varsayılan olarak devre dışıdır**. Bu, potansiyel olarak zararlı işlemlerin otomatik çalışmasını önler.
+
+### Araçları Etkinleştirme
+
+Claude Code'un tam işlevselliğinden yararlanmak için araçları manuel olarak etkinleştirmen gerekir:
+
+1. **Araç Ayarlarını Aç** — Kenar çubuğundaki dişli simgesine tıkla
+2. **Seçerek Etkinleştir** — Yalnızca ihtiyacın olan araçları aç
+3. **Ayarları Uygula** — Tercihlerin yerel olarak kaydedilir
+
+<div align="center">
+
+![Araç Ayarları Modalı](public/screenshots/tools-modal.png)
+*Araç Ayarları arayüzü — yalnızca ihtiyacın olanı etkinleştir*
+
+</div>
+
+**Önerilen yaklaşım**: Temel araçlarla başla ve gerektikçe daha fazlasını ekle. Bu ayarları sonra her zaman değiştirebilirsin.
+
+---
+
+## Eklentiler
+
+CloudCLI, kendi frontend UI'sı ve isteğe bağlı Node.js arka ucu olan özel sekmeler eklemeni sağlayan bir eklenti sistemine sahiptir. Git depolarından eklentileri doğrudan **Ayarlar > Eklentiler**'den yükleyebilir veya kendi eklentini yazabilirsin.
+
+### Mevcut Eklentiler
+
+| Eklenti | Açıklama |
+|---|---|
+| **[Project Stats](https://github.com/cloudcli-ai/cloudcli-plugin-starter)** | Mevcut projen için dosya sayıları, kod satırları, dosya türü dağılımı, en büyük dosyalar ve son değiştirilen dosyaları gösterir |
+| **[Web Terminal](https://github.com/cloudcli-ai/cloudcli-plugin-terminal)** | Çoklu sekme destekli tam xterm.js terminali |
+
+### Kendi Eklentini Yaz
+
+**[Plugin Starter Şablonu →](https://github.com/cloudcli-ai/cloudcli-plugin-starter)** — kendi eklentini oluşturmak için bu repo'yu fork'la. Frontend render, canlı bağlam güncellemeleri ve arka uç sunucusuyla RPC iletişimi içeren çalışan bir örnek içerir.

+## Sık Sorulan Sorular
+
+<details>
+<summary>Bu Claude Code Remote Control'dan nasıl farklı?</summary>
+
+Claude Code Remote Control, yerel terminalinde zaten çalışan bir oturuma mesaj göndermeni sağlar. Makinen açık kalmak zorunda, terminalin açık kalmak zorunda ve ağ bağlantısı olmadan yaklaşık 10 dakika sonra oturumlar zaman aşımına uğrar.
+
+CloudCLI UI ve CloudCLI Cloud, Claude Code'un yanında değil içinde çalışır — MCP sunucuların, izinlerin, ayarların ve oturumların, Claude Code'un yerel olarak kullandığının birebir aynısıdır. Hiçbir şey çoğaltılmaz veya ayrı yönetilmez.
+
+Pratikte bu ne demek:
+
+- **Tek oturum değil, tüm oturumların** — CloudCLI UI, `~/.claude` klasöründeki her oturumu otomatik keşfeder. Remote Control yalnızca tek aktif oturumu Claude mobil uygulamasına açar.
+- **Ayarların sana ait** — UI'da değiştirdiğin MCP sunucuları, araç izinleri ve proje yapılandırması doğrudan Claude Code yapılandırmana yazılır ve anında etkili olur; tersi de geçerli.
+- **Daha fazla ajanla çalışır** — Sadece Claude Code değil; Cursor CLI, Codex ve Gemini CLI de.
+- **Sadece sohbet penceresi değil, tam UI** — dosya gezgini, Git entegrasyonu, MCP yönetimi ve shell terminali hepsi yerleşik.
+- **CloudCLI Cloud bulutta çalışır** — laptop'unu kapat, ajan çalışmaya devam eder. Beklemen gereken terminal yok, uyanık tutman gereken makine yok.
+
+</details>
+
+<details>
+<summary>AI aboneliği için ayrıca ödeme yapmam gerekiyor mu?</summary>
+
+Evet. CloudCLI AI'yi değil, ortamı sağlar. Kendi Claude, Cursor, Codex veya Gemini aboneliğini getirirsin. CloudCLI Cloud, barındırılan ortam için aylık 7 $'dan başlar — bunun üzerine eklenir.
+
+</details>
+
+<details>
+<summary>CloudCLI UI'yi telefonumda kullanabilir miyim?</summary>
+
+Evet. Kendin barındırdığında, sunucuyu makinende çalıştır ve ağındaki herhangi bir tarayıcıda `[yourip]:port` adresini aç. CloudCLI Cloud için, herhangi bir cihazdan aç — VPN yok, port yönlendirme yok, kurulum yok. Native bir uygulama da hazırlanıyor.
+
+</details>
+
+<details>
+<summary>UI'da yaptığım değişiklikler yerel Claude Code kurulumumu etkiler mi?</summary>
+
+Evet, kendin barındırdığında. CloudCLI UI, Claude Code'un yerel olarak kullandığı aynı `~/.claude` yapılandırmasından okur ve ona yazar. UI üzerinden eklediğin MCP sunucuları Claude Code'da anında görünür; tersi de geçerli.

+# Providers Module Guide
+
+This file documents the current provider contract in `server/modules/providers`.
+Keep it current whenever provider wiring, skill discovery, or session sync
+behavior changes. The goal is that a human or AI agent can add a new provider
+without guessing which files need to move.
+
+## Current Provider Shape
+
+Every provider wrapper exposes five facets:
+
+- `auth`
+- `mcp`
+- `skills`
+- `sessions`
+- `sessionSynchronizer`
+
+These correspond to the shared interfaces in `server/shared/interfaces.ts`:
+
+- `IProviderAuth`
+- `IProviderMcp`
+- `IProviderSkills`
+- `IProviderSessions`
+- `IProviderSessionSynchronizer`
+
+The services that consume them are:
+
+- `providerAuthService`
+- `providerMcpService`
+- `providerSkillsService`
+- `sessionsService`
+- `sessionSynchronizerService`
+
+Current provider ids in this repo are:
+
+- `claude`
+- `codex`
+- `cursor`
+- `gemini`
+
+Those ids are mirrored in backend unions and frontend provider constants. If
+adding a new provider, update every place that hardcodes this list.
+
+## Current File Layout
+
+Each provider lives under its own folder in `server/modules/providers/list/`:
+
+```text
+server/modules/providers/list/<provider>/
+  <provider>.provider.ts
+  <provider>-auth.provider.ts
+  <provider>-mcp.provider.ts
+  <provider>-skills.provider.ts
+  <provider>-sessions.provider.ts
+  <provider>-session-synchronizer.provider.ts
+```
+
+The existing provider folders are `claude`, `codex`, `cursor`, and `gemini`.
+
+## What Each Facet Does
+
+| Facet | Responsibility | Base / Service |
+| --- | --- | --- |
+| `auth` | Report install/auth state for the provider runtime | `IProviderAuth` -> `providerAuthService` |
+| `mcp` | Read, list, write, and remove provider-native MCP config | `McpProvider` -> `providerMcpService` |
+| `skills` | Discover provider-native skill markdown files | `SkillsProvider` -> `providerSkillsService` |
+| `sessions` | Normalize live events and fetch session history | `IProviderSessions` -> `sessionsService` |
+| `sessionSynchronizer` | Scan transcript artifacts and upsert session metadata | `IProviderSessionSynchronizer` -> `sessionSynchronizerService` |
+
+`sessions` and `sessionSynchronizer` are separate concerns:
+
+- `sessions` handles runtime event normalization and history fetches.
+- `sessionSynchronizer` handles file-backed session indexing into `sessionsDb`.
+
+## How To Add A Provider
+
+1. Add the provider id everywhere it is part of the contract.
+
+- Update `server/shared/types.ts` `LLMProvider`.
+- Update `src/types/app.ts` `LLMProvider` if the frontend should know about it.
+- Update `server/modules/providers/provider.routes.ts`.
+- Update `server/routes/agent.js` if the provider is launchable from the agent runtime.
+- Update `server/index.js` if the provider needs runtime boot or shutdown wiring.
+- Update `shared/modelConstants.js` if the provider appears in UI provider pickers.
+- Update `src/components/chat/hooks/useChatProviderState.ts` and
+  `src/components/chat/view/subcomponents/ProviderSelectionEmptyState.tsx` if
+  the provider should be selectable in chat.
+- Update `src/components/provider-auth/view/ProviderLoginModal.tsx` if the
+  provider has a login/setup flow.
+
+2. Create the wrapper class.
+
+- Add `server/modules/providers/list/<provider>/<provider>.provider.ts`.
+- Extend `AbstractProvider`.
+- Expose readonly `auth`, `mcp`, `skills`, `sessions`, and `sessionSynchronizer`.
+- Call `super('<provider>')`.
+
+3. Implement auth.
+
+- Return a full `ProviderAuthStatus`.
+- Treat normal `not installed` / `not authenticated` states as data, not exceptions.
+- Keep provider-specific credential discovery inside the auth provider.
+- If the provider has no auth step, return a stable unauthenticated or not-installed status instead of omitting the facet.
+
+4. Implement MCP.
+
+- Extend `McpProvider`.
+- Pass the supported scopes and transports to `super(...)`.
+- Implement the four required methods:
+  - `readScopedServers(...)`
+  - `writeScopedServers(...)`
+  - `buildServerConfig(...)`
+  - `normalizeServerConfig(...)`
+- Use the shared validation and normalization behavior from `McpProvider`.
+- Keep the provider-specific config format local to the provider implementation.
+
+Current MCP formats in this repo are:
+
+| Provider | User / Project Storage | Supported Scopes | Supported Transports |
+| --- | --- | --- | --- |
+| Claude | `.mcp.json` in user / local / project locations | `user`, `local`, `project` | `stdio`, `http`, `sse` |
+| Codex | `.codex/config.toml` | `user`, `project` | `stdio`, `http` |
+| Cursor | `.cursor/mcp.json` | `user`, `project` | `stdio`, `http` |
+| Gemini | `.gemini/settings.json` | `user`, `project` | `stdio`, `http` |
+
+5. Implement skills.
+
+- Extend `SkillsProvider`.
+- Implement `getSkillSources(workspacePath)`.
+- Return the actual discovery roots for the provider.
+- Skills are discovered from `SKILL.md` files.
+- `readProviderSkillMarkdownDefinition(...)` reads front matter `name` and `description`.
+- If `name` is missing, the parent directory name is used as a fallback.
+- Use `recursive: true` only when the provider stores skills in nested trees.
+- Keep the emitted `command` string aligned with the provider's real skill syntax.
+
+Current skill discovery roots are:
+
+| Provider | User Roots | Project / Repo Roots | Prefix | Notes |
+| --- | --- | --- | --- | --- |
+| Claude | `~/.claude/skills` | `<workspace>/.claude/skills` | `/` | Also discovers Claude plugin skills from enabled plugin installs. Command skills live under `commands/`; markdown skills live under `skills/` and are scanned recursively. |
+| Codex | `~/.agents/skills`, `~/.codex/skills/.system`, `/etc/codex/skills` | `<workspace>/.agents/skills`, `path.dirname(workspacePath)/.agents/skills`, topmost git root `.agents/skills` | `$` | Overlapping roots are deduplicated before scanning. |
+| Cursor | `~/.cursor/skills` | `<workspace>/.cursor/skills`, `<workspace>/.agents/skills` | `/` | Uses slash-style commands. |
+| Gemini | `~/.gemini/skills`, `~/.agents/skills` | `<workspace>/.gemini/skills`, `<workspace>/.agents/skills` | `/` | Uses slash-style commands. |
+
+Command forms currently used by the providers are:
+
+- Claude user/project skills: `/skill-name`
+- Claude plugin skills: `/plugin-name:skill-name`
+- Codex skills: `$skill-name`
+- Cursor skills: `/skill-name`
+- Gemini skills: `/skill-name`
+
+6. Implement sessions.
+
+- Implement `normalizeMessage(raw, sessionId)` and `fetchHistory(sessionId, options)`.
+- Use `createNormalizedMessage(...)` and `generateMessageId(...)` for emitted messages.
+- Keep normalized message ids unique. If one raw event produces multiple text
+  parts, append a discriminator so ids do not collide.
+- Keep pagination consistent:
+  - `limit: null` means unbounded/full history.
+  - `limit: 0` means an empty page.
+  - always return `total`, `hasMore`, `offset`, and `limit` when paginating.
+- Sanitize any filesystem-derived ids before using them in file or database paths.
+- Do not assume a provider's history format matches another provider's format.
+
+7. Implement session synchronization.
+
+- Implement `synchronize(since?: Date)` to scan provider artifacts and upsert
+  sessions into `sessionsDb`.
+- Implement `synchronizeFile(filePath)` for single-file watcher updates.
+- Use the existing helpers when they fit:
+  - `buildLookupMap(...)`
+  - `extractFirstValidJsonlData(...)`
+  - `findFilesRecursivelyCreatedAfter(...)`
+  - `normalizeSessionName(...)`
+  - `readFileTimestamps(...)`
+- Make the sync resilient to partial, malformed, or missing provider files.
+- The orchestration service runs all provider synchronizers and only advances
+  `scan_state.last_scanned_at` when every provider succeeds.
+
+Current session sync roots are:
+
+| Provider | Scan Roots | Metadata Helpers / Notes |
+| --- | --- | --- |
+| Claude | `~/.claude/projects/**/*.jsonl` | Uses `~/.claude/history.jsonl` for name lookup and the trailing `ai-title`, `last-prompt`, or `custom-title` entries for title recovery. |
+| Codex | `~/.codex/sessions/**/*.jsonl` | Uses `~/.codex/session_index.jsonl` for title lookup and the last `task_complete` message for a fallback title. |
+| Cursor | `~/.cursor/projects/**/*.jsonl` | Uses sibling `worker.log` to recover `workspacePath`, then derives the session title from the first user prompt. |
+| Gemini | `~/.gemini/tmp/**/*.jsonl` | Current full scans only index temp JSONL chat artifacts. Single-file sync also accepts legacy `.json` files. |
+
+8. Register the provider.
+
+- Add the new provider class to `server/modules/providers/provider.registry.ts`.
+- Update `server/modules/providers/provider.routes.ts` provider parsing.
+- If the provider introduces a new service or lifecycle hook, export it from the module entrypoint that consumes providers.
+
+9. Wire runtime and UI surfaces outside the providers module when needed.
+
+If the provider can run live chat sessions, update the runtime entrypoints too:
+
+- `server/routes/agent.js`
+- `server/index.js`
+
+If the provider is visible in the UI, update:
+
+- `shared/modelConstants.js`
+- `src/components/chat/hooks/useChatProviderState.ts`
+- `src/components/chat/view/subcomponents/ProviderSelectionEmptyState.tsx`
+- `src/components/provider-auth/view/ProviderLoginModal.tsx`

+```
+
+## Minimal Skills Template
+
+```ts
+import path from 'node:path';
+
+import { SkillsProvider } from '@/modules/providers/shared/skills/skills.provider.js';
+import type { ProviderSkillSource } from '@/shared/types.js';
+
+export class <Provider>SkillsProvider extends SkillsProvider {
+  constructor() {
+    super('<provider>');
+  }
+
+  protected async getSkillSources(workspacePath: string): Promise<ProviderSkillSource[]> {
+    return [
+      {
+        scope: 'project',
+        rootDir: path.join(workspacePath, '.<provider>', 'skills'),
+        commandPrefix: '/',
+      },
+    ];
+  }
+}
+```
+
+## Minimal Session Sync Template
+
+```ts
+import type { IProviderSessionSynchronizer } from '@/shared/interfaces.js';
+
+export class <Provider>SessionSynchronizer implements IProviderSessionSynchronizer {
+  async synchronize(since?: Date): Promise<number> {
+    return 0;
+  }
+
+  async synchronizeFile(filePath: string): Promise<string | null> {
+    return null;
+  }
+}
+```
+
+## AI Prompt Template
+
+Use this prompt when asking an AI agent to add a provider:
+
+```text
+Add a new provider "<provider>" using the current provider module architecture.
+
+Requirements:
+1) Create:
+   - server/modules/providers/list/<provider>/<provider>.provider.ts
+   - server/modules/providers/list/<provider>/<provider>-auth.provider.ts
+   - server/modules/providers/list/<provider>/<provider>-mcp.provider.ts
+   - server/modules/providers/list/<provider>/<provider>-skills.provider.ts
+   - server/modules/providers/list/<provider>/<provider>-sessions.provider.ts
+   - server/modules/providers/list/<provider>/<provider>-session-synchronizer.provider.ts
+2) Register in:
+   - server/modules/providers/provider.registry.ts
+   - server/modules/providers/provider.routes.ts
+   - server/shared/types.ts LLMProvider
+   - src/types/app.ts LLMProvider
+3) Mirror the nearest existing provider implementation for file naming, style,
+   and error handling.
+4) Implement skills support with SkillsProvider and the current skill roots.
+5) Implement session synchronization if the provider stores transcript files.
+6) Ensure sessions use unique ids, safe path handling, and correct pagination.
+7) Keep `sessions` and `sessionSynchronizer` separate.
+8) Run:
+   - npx eslint <touched files>
+   - npx tsc --noEmit -p server/tsconfig.json
+```
+
+## Validation
+
+After adding or changing a provider, run the relevant checks:
+
+```bash
+npx eslint server/modules/providers/**/*.ts server/shared/types.ts server/shared/interfaces.ts
+npx tsc --noEmit -p server/tsconfig.json
+```
+
+Useful tests in this repo:
+
+- `server/modules/providers/tests/mcp.test.ts`
+- `server/modules/providers/tests/skills.test.ts`
+
+If you touch sessions or session synchronization, add or update focused tests
+alongside the implementation.
+
+## Common Mistakes
+
+- Adding provider files but forgetting `provider.registry.ts` or
+  `provider.routes.ts`.
+- Updating backend provider ids but not `src/types/app.ts` or the frontend
+  provider constants.
+- Omitting `skills` or `sessionSynchronizer` from the wrapper.
+- Returning duplicate normalized message ids for split content.
+- Treating `limit === 0` as unbounded history.
+- Building file paths from raw session ids without validation.
+- Hardcoding a skill root without checking the provider's actual discovery rules.
+- Forgetting that Claude plugin skills are discovered differently from normal
+  user/project skill folders.
+- Assuming one provider's MCP config file format works for the others.

+# WebSocket Module
+
+This module owns the server-side WebSocket gateway used by:
+
+1. Chat streaming (`/ws`)
+2. Interactive terminal sessions (`/shell`)
+3. Plugin WebSocket passthrough (`/plugin-ws/:pluginName`)
+
+It is intentionally structured as **small services** plus a **barrel export** in `index.ts`.
+
+## Public API
+
+`server/modules/websocket/index.ts` exports:
+
+1. `createWebSocketServer(server, dependencies)`  
+Creates and wires the shared `ws` server.
+2. `connectedClients` and `WS_OPEN_STATE`  
+Shared chat client registry and open-state constant used by other modules.
+
+## Why Dependency Injection Is Used
+
+The module receives runtime-specific functions from `server/index.js` instead of importing legacy runtime files directly.
+
+Benefits:
+
+1. Keeps module boundaries clean (`server/modules/*` architecture rule).
+2. Makes each service easier to test in isolation.
+3. Keeps WebSocket transport concerns separate from provider runtime concerns.
+
+## Service Map
+
+| File | Responsibility |
+|---|---|
+| `services/websocket-server.service.ts` | Creates `WebSocketServer`, binds `verifyClient`, routes connection by pathname |
+| `services/websocket-auth.service.ts` | Authenticates upgrade requests and attaches `request.user` |
+| `services/chat-websocket.service.ts` | Handles `/ws` chat protocol and provider command/session control messages |
+| `services/shell-websocket.service.ts` | Handles `/shell` PTY lifecycle, reconnect buffering, auth URL detection |
+| `services/plugin-websocket-proxy.service.ts` | Bridges client socket to plugin socket |
+| `services/websocket-writer.service.ts` | Adapts raw WebSocket to writer interface (`send`, `setSessionId`, `getSessionId`) |
+| `services/websocket-state.service.ts` | Holds shared chat client set and open-state constant |
+

+      Router->>Proxy: handlePluginWsProxy(ws, pathname, getPluginPort)
+    else unknown
+      Router->>Router: ws.close()
+    end
+  end
+```
+
+## `/ws` Chat Flow
+
+When a chat socket connects:
+
+1. Add socket to `connectedClients`.
+2. Build `WebSocketWriter` (captures `userId` from authenticated request).
+3. Parse each incoming message with `parseIncomingJsonObject`.
+4. Dispatch by `data.type`.
+5. On close, remove socket from `connectedClients`.
+
+### Chat Message Dispatch
+
+```mermaid
+flowchart TD
+  A[Incoming WS message] --> B[parseIncomingJsonObject]
+  B -->|invalid| C[send {type:error}]
+  B -->|ok| D{data.type}
+
+  D -->|claude-command| E[queryClaudeSDK]
+  D -->|cursor-command| F[spawnCursor]
+  D -->|codex-command| G[queryCodex]
+  D -->|gemini-command| H[spawnGemini]
+  D -->|cursor-resume| I[spawnCursor resume]
+  D -->|abort-session| J[abort by provider]
+  D -->|claude-permission-response| K[resolveToolApproval]
+  D -->|cursor-abort| L[abortCursorSession]
+  D -->|check-session-status| M[is*SessionActive + optional reconnectSessionWriter]
+  D -->|get-pending-permissions| N[getPendingApprovalsForSession]
+  D -->|get-active-sessions| O[getActive*Sessions]
+```
+
+### Chat Notes
+
+1. `abort-session` returns a normalized `complete` message with `aborted: true`.
+2. `check-session-status` returns `{ type: "session-status", isProcessing }`.
+3. Claude status checks can reconnect output stream to the new socket via `reconnectSessionWriter`.
+
+## `/shell` Terminal Flow
+
+The shell handler manages persistent PTY sessions keyed by:
+
+`<projectPath>_<sessionIdOrDefault>[_cmd_<hash>]`
+
+This enables reconnect behavior and isolates command-specific plain-shell sessions.
+
+### Shell Lifecycle
+
+```mermaid
+stateDiagram-v2
+  [*] --> WaitingInit
+  WaitingInit --> ValidateInit: message.type == init
+  ValidateInit --> ReconnectExisting: session key exists and not login reset
+  ValidateInit --> SpawnNewPTY: valid path + valid sessionId
+  ValidateInit --> EmitError: invalid payload/path/sessionId
+
+  ReconnectExisting --> Running: attach ws, replay buffer
+  SpawnNewPTY --> Running: pty.spawn + wire onData/onExit
+
+  Running --> Running: input -> pty.write
+  Running --> Running: resize -> pty.resize
+  Running --> Running: onData -> buffer + output + auth_url detection
+  Running --> Exited: onExit
+  Running --> Detached: ws close
+
+  Detached --> Running: reconnect before timeout
+  Detached --> Killed: timeout reached -> pty.kill
+  Exited --> [*]
+  Killed --> [*]
+  EmitError --> WaitingInit
+```
+
+### Shell Behaviors in Detail
+
+1. `init`:
+Reads `projectPath`, `sessionId`, `provider`, `hasSession`, `initialCommand`, `isPlainShell`.
+2. Login reset:
+For login-like commands, existing keyed PTY session is killed and recreated.
+3. Validation:
+Path must exist and be a directory; `sessionId` must match safe pattern.
+4. Command build:
+Provider-specific command construction with resume semantics.
+5. PTY output buffering:
+Stores up to 5000 chunks for replay on reconnect.
+6. URL detection:
+Strips ANSI, accumulates text buffer, extracts URLs, emits `auth_url` once per normalized URL, supports `autoOpen`.
+7. Close behavior:
+Socket disconnect does not instantly kill PTY; session is kept alive and terminated on timeout.
+
+## `/plugin-ws/:pluginName` Proxy Flow
+
+```mermaid
+sequenceDiagram
+  participant Client
+  participant Proxy as handlePluginWsProxy
+  participant PM as getPluginPort
+  participant Upstream as Plugin WS
+
+  Client->>Proxy: Connect /plugin-ws/:name
+  Proxy->>Proxy: Validate pluginName regex
+  alt Invalid name
+    Proxy-->>Client: close(4400, "Invalid plugin name")
+  else Valid
+    Proxy->>PM: getPluginPort(name)
+    alt Plugin not running
+      Proxy-->>Client: close(4404, "Plugin not running")
+    else Port found
+      Proxy->>Upstream: new WebSocket(ws://127.0.0.1:port/ws)
+      Client-->>Upstream: relay messages bidirectionally
+      Upstream-->>Client: relay messages bidirectionally
+      Upstream-->>Client: close propagation
+      Client-->>Upstream: close propagation
+      Upstream-->>Client: close(4502, "Upstream error") on upstream error
+    end
+  end
+```
+
+## Shared Client Registry and Broadcasts
+
+Only chat sockets (`/ws`) are tracked in `connectedClients`.
+
+That shared set is consumed by:
+
+1. `modules/projects/services/projects-with-sessions-fetch.service.ts`
+Broadcasts `loading_progress` while project snapshots are being built.
+2. `modules/providers/services/sessions-watcher.service.ts`
+Broadcasts `projects_updated` when provider session artifacts change.
+
+This design centralizes cross-module realtime fanout without requiring route-local references to WebSocket internals.
+
+## Writer Adapter (`WebSocketWriter`)
+
+`WebSocketWriter` normalizes chat transport behavior to match existing writer-style interfaces used elsewhere.
+
+Methods:
+
+1. `send(data)`  
+JSON-serializes and sends only if socket is open.
+2. `setSessionId(sessionId)` / `getSessionId()`  
+Supports provider session bookkeeping and resume flows.
+3. `updateWebSocket(newRawWs)`  
+Allows active session stream redirection on reconnect.
+
+## Error Handling and Close Codes
+
+Current explicit close codes in this module:
+
+1. `4400`: Invalid plugin name
+2. `4404`: Plugin not running
+3. `4502`: Upstream plugin WebSocket error
+
+Other errors:
+
+1. Chat handler catches and emits `{ type: "error", error }`.
+2. Shell handler catches and writes terminal-visible error output.
+3. Unknown websocket paths are closed immediately.
+
+## Extending This Module
+
+To add a new websocket route:
+
+1. Add a new handler service under `services/`.
+2. Extend `WebSocketServerDependencies` in `websocket-server.service.ts` if needed.
+3. Add a new pathname branch in the router.
+4. Wire dependency injection from `server/index.js`.
+5. Keep `index.ts` as barrel-only export surface.
