+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a Python-based local AI assistant called "halp" that provides a GUI interface for running shell commands via an AI agent. The application uses a local language model (Yi-Coder-1.5B-Chat) to interpret user requests and execute shell commands accordingly.
+
+## Key Components
+
+- **local_agent_ui.py**: Main application with GUI interface using customtkinter, AI model integration, and shell command execution capabilities
+- **install_right_click.py**: Windows registry installer that adds a right-click context menu option to launch the assistant from any folder
+
+## Dependencies
+
+The project requires these Python packages:
+- customtkinter (GUI framework)
+- torch (PyTorch for model inference)
+- transformers (Hugging Face transformers library)
+- pynput (keyboard hotkey detection)
+- protobuf (protocol buffers for tokenizer)
+- sentencepiece (tokenizer backend)
+
+### Installation
+```bash
+pip install customtkinter torch transformers pynput protobuf sentencepiece
+```
+
+## Development Commands
+
+### Running the Application
+```bash
+python3 local_agent_ui.py [optional_working_directory]
+```
+
+### Installing Right-Click Context Menu (Windows)
+```bash
+python3 install_right_click.py
+```
+
+### Uninstalling Right-Click Context Menu (Windows)
+```bash
+python3 install_right_click.py uninstall
+```
+
+## Architecture
+
+The application follows a multi-threaded architecture:
+1. **Main UI Thread**: Handles the customtkinter GUI, message display, and user input
+2. **AI Processing Thread**: Runs the language model inference and command execution logic
+3. **Keyboard Listener**: Global hotkey detection (backtick key by default) for showing/hiding the window
+
+### Key Features
+- **Global Hotkey**: Press backtick (`) to toggle window visibility
+- **Context-Aware**: Launches with the current working directory as context
+- **Command Execution**: AI agent can execute shell commands and observe results
+- **Conversational Loop**: Multi-step reasoning with up to 5 iterations per task
+
+### AI Agent Workflow
+1. User provides a task
+2. AI generates reasoning and potential shell commands
+3. Commands are executed with stdout/stderr captured
+4. Results are fed back to the AI for next steps
+5. Process continues until "DONE" or iteration limit reached
+
+## Configuration
+
+Key configuration constants in local_agent_ui.py:
+- `MODEL_ID`: "01-ai/Yi-Coder-1.5B-Chat" (can be changed to other compatible models)
+- `HOTKEY`: Backtick key for window toggle
+- Iteration limit: 5 steps per task to prevent loops
+
+## Platform Notes
+
+- Designed primarily for Windows (uses Windows registry for context menu)
+- Shell commands executed with `shell=True` for Windows compatibility
+- Working directory context passed via command line arguments
