-# PicoClaw Launcher
-
-> [!WARNING]
-> This project is a temporary solution and will be refactored in the future to provide a complete web service. Therefore, the APIs in this directory are not stable.
-
-A standalone launcher for PicoClaw, providing visual JSON editing and OAuth provider authentication management.
-
-## Features
-
-- 📝 **Config Editor** — Sidebar-based settings UI with model management, channel configuration forms, and a raw JSON editor
-- 🤖 **Model Management** — Model card grid with availability status (grayed out without API key), primary model selection, add/edit/delete with required/optional field separation
-- 📡 **Channel Configuration** — Form-based settings for 12 channel types (Telegram, Discord, Slack, WeCom, DingTalk, Feishu, LINE, WhatsApp, QQ, OneBot, MaixCAM, etc.) with documentation links
-- 🔐 **Provider Auth** — Login to OpenAI (Device Code), Anthropic (API Token), Google Antigravity (Browser OAuth)
-- 🌐 **Embedded Frontend** — Compiles to a single binary with no external dependencies
-- 🌍 **i18n** — Chinese/English language switching with browser auto-detection
-- 🎨 **Theme** — Light / Dark / System theme toggle with localStorage persistence

-}
-```
-
----
-
-#### PUT /api/config
-
-Saves the configuration. The request body must be a complete Config JSON object.
-
-**Request Body** — `application/json`
-
-```json
-{
-  "agents": { "defaults": { "model_name": "gpt-5.2" } },
-  "model_list": [
-    {
-      "model_name": "gpt-5.2",

-
-**Response** `200 OK`
-
-```json
-{
-  "providers": [
-    {
-      "provider": "openai",
-      "auth_method": "oauth",
-      "status": "active",
-      "account_id": "user-xxx",
-      "expires_at": "2026-03-01T00:00:00Z"
-    }
-  ],
-  "pending_device": {
-    "provider": "openai",
-    "status": "pending",
-    "device_url": "https://auth.openai.com/activate",
-    "user_code": "ABCD-1234"
-  }
-}
-```
-
-`status` values: `active` | `expired` | `needs_refresh`
-
-`pending_device` is only present when a device code login is in progress.
-
----
-
-#### POST /api/auth/login
-
-Initiates a provider login.
-
-**Request Body** — `application/json`
-
-```json
-{ "provider": "openai" }
-```
-
-Supported `provider` values: `openai` | `anthropic` | `google-antigravity`
-
-##### OpenAI (Device Code Flow)
-
-Returns device code info. The server polls for completion in the background.
-
-```json
-{

-  "device_url": "https://auth.openai.com/activate",
-  "user_code": "ABCD-1234",
-  "message": "Open the URL and enter the code to authenticate."
-}
-```

-The user opens `device_url` in a browser and enters `user_code`. Once authenticated, `GET /api/auth/status` will show `pending_device.status` as `success`.
-
-##### Anthropic (API Token)
-
-Requires a `token` field in the request:
-
-```json
-{ "provider": "anthropic", "token": "sk-ant-xxx" }
-```

-{
-  "status": "redirect",
-  "auth_url": "https://accounts.google.com/o/oauth2/auth?...",
-  "message": "Open the URL to authenticate with Google."
-}
-```
-
-After authentication, Google redirects to `GET /auth/callback`, which saves the credentials and redirects back to the picoclaw-config UI.
-
----
-
-#### POST /api/auth/logout
-
-Logs out from a provider.
-
-**Request Body** — `application/json`

-
-**Response** `200 OK`
-
-```json
-{ "status": "ok" }
-```
-
----
-
-#### GET /auth/callback
-
-OAuth browser callback endpoint (used by Google Antigravity). Called by the OAuth provider's redirect — **not invoked directly by the frontend**.
-
-**Query Parameters:**

-
-**Response** `200 OK`
-
-```json
-{

 ## MCP Tool
 
 The MCP tool enables integration with external Model Context Protocol servers.
 
+### Tool Discovery (Lazy Loading)
+
+When connecting to multiple MCP servers, exposing hundreds of tools simultaneously can exhaust the LLM's context window
+and increase API costs. The **Discovery** feature solves this by keeping MCP tools *hidden* by default.
+
+Instead of loading all tools, the LLM is provided with a lightweight search tool (using BM25 keyword matching or Regex).
+When the LLM needs a specific capability, it searches the hidden library. Matching tools are then temporarily "unlocked"
+and injected into the context for a configured number of turns (`ttl`).

+# Picoclaw Web
+
+This directory contains the standalone web service for `picoclaw`.
+It provides a complete unified web interface, acting as a dashboard, configuration center, and interactive console (channel client) for the core `picoclaw` engine.
+
+## Architecture
+
+The service is structured as a monorepo containing both the backend and frontend code to ensure high cohesion and simplify deployment.
+
+*   **`backend/`**: The Go-based web server. It provides RESTful APIs, manages WebSocket connections for chat, and handles the lifecycle of the `picoclaw` process. It eventually embeds the compiled frontend assets into a single executable.
+*   **`frontend/`**: The Vite + React + TanStack Router single-page application (SPA). It provides the interactive user interface.
+
+## Getting Started
+
+### Prerequisites
+
+*   Go 1.25+
+*   Node.js 20+ with pnpm
+
+### Development
+
+Run both the frontend dev server and the Go backend simultaneously:
+
+```bash
+make dev
+```
+
+Or run them separately:
+
+```bash
+make dev-frontend   # Vite dev server
+make dev-backend    # Go backend
+```
+
+### Build
+
+Build the frontend and embed it into a single Go binary:
+
+```bash
+make build
+```
+
+The output binary is `backend/picoclaw-web`.
+
+### Other Commands
+
+```bash
+make test    # Run backend tests and frontend lint
+make lint    # Run go vet and prettier/eslint
+make clean   # Remove all build artifacts
+```
