 # Active Context
 
 ## Current Focus
-Finalizing documentation and preparing for task completion after implementing development mode support for webview loading.
+Renaming project to "Zen Coder" and enhancing tool functionality based on Vercel AI SDK documentation (tool activation, multi-step, error handling, repair).
 
 ## Recent Changes
-- Completed core MVP functionality.
-- Refactored Webview UI to Vite + Preact.
-- Implemented Model Selection UI and logic.
-- Updated relevant files (`package.json`, `src/extension.ts`, `webview-ui/*`) for Vite + Preact.
-- Fixed Webview Loading Issue for production builds.
-- **Implemented Development Mode Support:**
-    - Updated `.vscode/launch.json` to use `npm: watch` as `preLaunchTask`.
-    - Modified `getWebviewContent` in `src/extension.ts` to detect `extensionMode` and load from Vite dev server (`http://localhost:5173`) in development or from `dist/webview` in production.
-    - Adjusted CSP policies for both modes.
-- **Fixed Preact Mount Point:** Corrected the target element ID in `webview-ui/src/main.tsx` from `#app` to `#root` to match the development HTML structure in `src/extension.ts`, resolving the "無野睇" issue in dev mode.
-- **Fixed TypeScript RootDir Issue (TS6059):** Modified the main `tsconfig.json` to explicitly include only the `src/**/*` directory, preventing the compiler from trying to process files in the separate `webview-ui` project.
-- **Fixed TypeScript DOM Type Errors (TS2304):** Added `"DOM"` to the `compilerOptions.lib` array in the main `tsconfig.json` to resolve type errors originating from `@ai-sdk/ui-utils` dependency.
-- **Fixed CORS Issue in Dev Mode:** Updated `webview-ui/vite.config.ts` to include `server: { cors: true }`, allowing the VS Code webview (`vscode-webview://`) to fetch resources from the Vite dev server (`http://localhost:5173`).
+- **Project Renamed to Zen Coder:** Updated `package.json`, `src/extension.ts`, `README.md`, and Memory Bank files (`projectbrief.md`, `productContext.md`, `.clinerules`). Updated `webview-ui/index.html` title and root element ID. Updated secret keys prefix in `aiService.ts`.
+- **Tool Enhancement (Vercel AI SDK):**
+    - Added configuration options in `package.json` for enabling/disabling individual tools (`zencoder.tools.*.enabled`).
+    - Modified `AiService` (`_getActiveToolNames`, `getAiResponseStream`) to read configuration and pass active tools via `experimental_activeTools` to `streamText`.
+    - Added `maxSteps: 5` to `streamText` call in `AiService` to enable multi-step tool execution.
+    - Added experimental tool error handling (`NoSuchToolError`, `InvalidToolArgumentsError`, `ToolExecutionError`) in `getAiResponseStream`.
+    - Added experimental tool repair (`experimental_repairToolCall` with re-ask strategy) to `streamText` call in `AiService`.
+    - Removed placeholder MCP executor logic from `src/extension.ts` and `AiService`. Updated `executeSearch` in `AiService` to reflect dependency on future MCP integration.
 
 ## Next Steps
-- Update `memory-bank/progress.md` to reflect all recent fixes (dev mode, mount point, tsconfig include, tsconfig lib, vite cors).
-- Commit the latest changes.
+- Update `memory-bank/progress.md` to reflect project renaming and tool enhancements.

 ## Active Decisions
-- Webview UI successfully refactored and loading correctly in both development (with HMR via Vite dev server) and production modes.
-- Model selection functionality implemented.
-- Core logic remains stable.
+- Project successfully renamed across relevant files.
+- Tool functionality enhanced with activation controls, multi-step capability, and basic error/repair handling based on Vercel AI SDK features.
+- Code prepared for potential future MCP integration.

 ## Problem Solved
 Provides a simple, integrated way for a developer to leverage various AI models (Anthropic, Google, OpenRouter, DeepSeek) directly within VS Code for coding assistance, without needing complex setups or switching contexts. Enables AI to interact with the workspace via defined tools.

+    - Added experimental tool error handling and repair (`experimental_repairToolCall`) in `AiService`.
 
 ## What's Left (Potential Future Enhancements)
 - Refine Preact component structure.
 - Refine tool execution logic (error handling, robustness, e.g., `fetch`).
 - Implement conversation history persistence.
 - Thorough testing and debugging.
 - Remove unused `@vscode/webview-ui-toolkit` dependency.
-- Replace placeholder MCP tool executor with actual implementation if available/needed.
+- Implement actual MCP client integration for tools like `search`.
 - Improve Markdown rendering in Preact UI.
 - Improve error handling in Preact UI.
 
 ## Current Status
-- **MVP + Model Selection + Dev Mode Complete & Functional:** Core functionality, API key management, model selection UI (Vite + Preact), and webview loading (supporting dev HMR) are implemented and working.
-- Project is in a stable, functional state meeting the extended requirements.
+- **Core Functionality Enhanced:** Project renamed to Zen Coder. Tool functionality improved with activation controls, multi-step capability, and experimental error handling/repair. Core chat, API key management, model selection, and dev/prod webview loading remain functional.
+- Project is stable with enhanced tool features based on Vercel AI SDK.
 
 ## Known Issues
 - `@vscode/webview-ui-toolkit` dependency is unused after refactor but still listed in `package.json`.
-- Search tool currently uses a placeholder MCP executor.
+- Search tool requires MCP integration to function.
 - Other tool implementations might need more robust error handling.
 - Conversation history is not persisted.
