From 14d19666339581597ec295a0223ac3e1302896a9 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 2 Mar 2026 00:21:02 +0000 Subject: [PATCH 01/13] =?UTF-8?q?feat:=20add=20Mothership=20backend=20(Pha?= =?UTF-8?q?se=201)=20=E2=80=94=20persistent=20events,=20cross-session=20sy?= =?UTF-8?q?nc?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces the Mothership, a headless Node.js/TypeScript backend that browser extension regents connect to via WebSocket. Extension works standalone when disconnected (zero breaking changes). Backend (mothership/): - Hono HTTP + ws WebSocket on single port (default 3001) - SQLite with WAL mode (users, workspaces, sessions, events, messages) - JWT auth (register, login, long-lived API tokens for extensions) - Lane Queue pattern (from OpenClaw) for per-session serial execution - Event bus broadcasting DB changes to WebSocket subscribers - REST API: /auth, /workspaces, /sessions, /events Extension changes: - background.js: WebSocket connection manager with auto-reconnect - RegentSidecar: forwards extracted events to mothership (fire-and-forget) - RegentOrchestrator: listens for cross-session events from mothership - RegentSidebar: connection status dot, remote session event display - Popup: Mothership settings section (URL, token, connect/disconnect)

Keys, custom endpoints, and preferences are stored only in `chrome.storage.sync` on your device. The Mothership backend is entirely self-hosted — your data never leaves your infrastructure. + +### Supported API Providers - [DeepSeek](https://deepseek.com) (official endpoint) -- [ByteDance Volcengine](https://www.volcengine.com/experience/ark?utm_term=202502dsinvite&ac=DSASUQY5&rc=OXTHJAF8) -- [SiliconFlow](https://cloud.siliconflow.cn/i/lStn36vH) +- [ByteDance Volcengine](https://www.volcengine.com/experience/ark) +- [SiliconFlow](https://cloud.siliconflow.cn) - [OpenRouter](https://openrouter.ai/models) -- [AiHubMix](https://aihubmix.com?aff=SmJB) +- [AiHubMix](https://aihubmix.com) - [Tencent Cloud](https://cloud.tencent.com/document/product/1772/115969) - [IFlytek Star](https://training.xfyun.cn/modelService) - [Baidu Cloud](https://console.bce.baidu.com/qianfan/modelcenter/model/buildIn/list) - [Aliyun](https://bailian.console.aliyun.com/#/model-market) -- Unlimited self-hosted/custom providers that expose an OpenAI-compatible `/chat/completions` endpoint - -## ✨ Feature Overview - -### 🪄 Inline Assistants -- Rich quick-action bubble appears beside any text selection with Chat, Copy, Translate (19 languages), Explain, Summarize, Email, and Analyze templates. -- SelectionPreservationManager keeps the DOM range alive so the bubble never steals your highlight during double/triple clicks or context-menu usage. -- Right-click context menu entry and toolbar popup both reuse the same flow, so highlighted text, manual prompts, and keyboard shortcuts share the session logic. - -### 🪟 Floating Workspace -- `interactjs` gives the chat window magnetic drag + resize handles, snap animations, and a persistent minimize icon whose position is saved per user. -- Toggle "Remember window size" to keep the workspace dimensions across sites, and "Pin window" to prevent accidental closes when clicking outside. -- Minimized state, popup visibility, and icon location are tracked by `popupStateManager`, ensuring state survives selection changes. -- Built-in input container includes auto-expanding textarea, send icon, abort/stop square, and smart focus rules so existing form inputs retain priority. -- Each answer provides inline copy + regenerate controls; DeepSeek-R1/openrouter reasoning is rendered above the final response with a collapsible panel. -- Auto-scroll follows the stream until you scroll manually. Scroll momentum + cooldown logic prevent janky jumps. - -### 🧠 Provider & Model Controls -- Popup UI (English/Chinese) manages API keys per provider, preferred language (auto-detect or force output), and whether the selection bubble is enabled. -- Add, rename, hide, or delete custom providers with their own base URL, display name, default model, and placeholder API-key links. -- ModelManager stores multiple custom models per provider. Dropdowns support inline delete buttons, and forms auto-save via TempStateManager so unfinished entries survive popup reloads. -- Configure a global custom system prompt used for every conversation, or override per quick action via templated prompts. - -### 📝 Rendering, Safety & UX Polishing -- Markdown-It + highlight.js + KaTeX + DOMPurify ensure rich formatting, syntax highlighting, math rendering, and sanitized HTML. -- Code blocks gain reusable “Copy” controls, while each AI block also exposes regenerate + share-ready text copy actions. -- Streaming is proxied through the background service worker using modern `fetch` + `AbortController`, so stop/regenerate/shortcut commands instantly cut network traffic. -- ThemeManager listens to `prefers-color-scheme` and toggles CSS variables to keep the popover and quick buttons readable in both modes. - -### ⌨️ Shortcuts & Invocation Options -- Two Chrome commands ship by default: - - `Ctrl/Cmd + Shift + Y` → toggle chat (new session) - - `Ctrl/Cmd + Shift + U` → show/hide chat (preserve session) -- Use `chrome://extensions/shortcuts` (or the “Shortcut Settings” link inside the popup) to rebind commands. -- Context menu entry (“DeepSeek AI”) sends the selected text directly, and the icon in the toolbar opens the configuration popup. - -### 🔐 Privacy & Onboarding -- On first install we open [`src/Instructions/Instructions.html`](src/Instructions/instructions.html), an offline-friendly Apple-style guide covering every screen. -- `PRIVACY.html` documents exactly what is stored (API keys + user preferences in local browser storage) and reminds you that no remote server is involved. -- DOMPurify sanitizes all rendered HTML, and no telemetry or analytics is collected. - -## 🔄 How It Works +- Any self-hosted/custom provider exposing an OpenAI-compatible `/chat/completions` endpoint + +--- + +## Architecture Overview + +```mermaid +graph TB + subgraph "Browser Extension" + CS[Content Script

Open `chrome://extensions` → enable **Developer mode** → **Load unpacked** → pick the `dist` folder. -2. To ship a store package, run one of: - - `pnpm run build:zip` → `extension.zip` - - `pnpm run build:chrome` → `chrome-submission.zip` - - `pnpm run build:edge` → `edge-submission.zip` -3. Upload the generated ZIP to the respective store dashboards. - -## 🧩 Setup & Daily Use -1. Click the extension icon to open the popup. -2. Choose a provider (or create a custom one with a name + base URL + default model) and paste its API key. Each provider keeps its own key and optional custom API URL. -3. Pick or add a model. Non-DeepSeek providers require an explicit model ID; the UI will auto-prompt you to add one if missing. -4. Configure behavior: - - Enable/disable the selection quick-action bubble. - - Choose automatic language detection or force a language from the dropdown (20+ locales). - - Toggle **Save Window Size**, **Pin Window**, and **Custom System Prompt**. - - Use the **Shortcut Settings** link to jump to Chrome’s command editor. -5. Highlight text (or open the chat via shortcut) → the quick-action bubble appears → select Chat or a template. You can also open the floating window first and paste custom prompts. -6. While streaming, use the stop square icon to abort. Each answer ends with copy + regenerate icons; reasoning blocks collapse/expand with one click. -7. Need a refresher? Open the in-extension [usage guide](src/Instructions/instructions.html) or switch to the Simplified Chinese README linked at the top. - -## ⌨️ Shortcuts & Quick Actions -- **Quick actions:** - - `Chat` → sends selection verbatim. - - `Copy` → copies selection without opening chat. - - `Translate` → language picker drives a prompt that asks DeepSeek to translate into your chosen target language. - - `Explain`, `Summarize`, `Email`, `Analyze` → curated prompts (with MBTI-flavored tone) for instant structured answers. -- **Window commands:** `toggle-chat` destroys and recreates the session; `show-hide-chat` keeps the current context alive between invocations; `close-chat` is exposed internally for context menu cleanup. -- **Context menu:** right-click → “DeepSeek AI” to push highlighted text directly into a new chat with a contextual greeting (morning/afternoon/evening). - -## 🏗️ Project Layout & Stack +1. Open `chrome://extensions` → enable **Developer mode** → **Load unpacked** → select `dist/`. +2. Click the extension icon → configure your API provider and key. +3.

From 77041add9c2a5fee3e8a969705197b32219f087f Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 2 Mar 2026 05:09:05 +0000 Subject: [PATCH 13/13] feat: refactor agent runtime to use Mastra framework MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace custom SSE parsing + manual tool loop with Mastra Agent as inner execution engine. Our orchestration shell (DB writes, bus events, safety limits, run tracking, MCP security) wraps Mastra for production control. New files: - agents/mcpBridge.ts: Bridge MCP tools → Mastra createTool() instances, preserving our security layer (command allowlist, SSRF, path traversal) - agents/modelResolver.ts: Map encrypted DB credentials → Mastra OpenAICompatibleConfig (DeepSeek, OpenRouter, SiliconFlow, OpenAI, custom) Changed: - agents/runtime.ts: Replace executeRun() internals — delete parseStream(), manual fetch(), PROVIDER_DEFAULTS, tool call assembly. Now uses MastraAgent.stream() with textStream + toolResults - README.md: Update architecture diagrams and agent docs for Mastra Deleted code: ~130 lines (SSE buffer parsing, manual HTTP, provider map, tool call index assembly) Added code: ~90 lines (mcpBridge, modelResolver, Mastra glue) Benefits: 800+ models / 47 providers, typed streaming, thinking/reasoning support, maintained by Gatsby team.
