+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+FileCtrl is a Terminal User Interface (TUI) file manager written in Rust using the Ratatui framework. It provides a keyboard-driven interface for file operations with extensive theming and configuration support.
+
+## Common Development Commands
+
+### Build and Run
+- `cargo build` - Build the project
+- `cargo build --release` - Build optimized release version
+- `cargo run` - Run the application
+- `cargo run -- <directory>` - Run with specific directory
+- `cargo run -- --write-config` - Write default config to ~/.config/filectrl/config.toml
+
+### Testing and Quality
+- `cargo test` - Run tests
+- `cargo clippy` - Run linter
+- `cargo fix --allow-dirty --allow-staged` - Auto-fix linting issues
+
+### Debugging
+- `RUST_LOG=debug cargo run 2>err` - Run with debug logging to ./err file
+- Set `log_level = "debug"` in config.toml for application-level logging
+
+### Git Hooks
+The project uses cargo-husky for git hooks. Pre-commit hooks run `cargo test` and `cargo check`. To modify hooks:
+1. Edit `[dev-dependencies.cargo-husky]` in Cargo.toml
+2. Remove `.git/hooks/pre-commit`
+3. Run `cargo clean && cargo test`
+
+## Architecture
+
+### Core Structure
+- `src/main.rs` - Entry point with CLI argument parsing using argh
+- `src/lib.rs` - Main library with logging configuration and app initialization
+- `src/app.rs` - Core application state and event loop
+- `src/views/` - UI components organized by responsibility
+- `src/file_system/` - File operations with async support and debouncing
+- `src/command/` - Command handling system with modes and tasks
+
+### Key Components
+
+#### Configuration System
+- `src/app/config/` - Configuration management
+- `default_config.toml` - Comprehensive default configuration with theming
+- Supports both truecolor and 256-color terminal themes
+- Configuration precedence: CLI option → ~/.config/filectrl/config.toml → built-in defaults
+
+#### File Operations
+- `src/file_system/` - Handles all file system operations
+- `async.rs` - Asynchronous file operations with buffering (64KB-64MB)
+- `watcher.rs` - File system change monitoring with notify crate
+- `debounce.rs` - Prevents excessive refreshes (100ms default)
+
+#### UI Architecture
+- Uses Ratatui for terminal UI rendering
+- `src/views/root.rs` - Main view coordinator
+- `src/views/table/` - File listing table with scrolling and selection
+- `src/views/prompt/` - Input handling for rename/filter operations
+- `src/views/status/` - Status bar with directory and selection info
+- `src/views/notices/` - Progress indicators and clipboard status
+
+#### Command System
+- `src/command/` - Command processing with different modes
+- Supports Normal, Filter, and Rename modes
+- Task-based async operations for file operations
+
+### Key Features
+- Extensive keyboard navigation (vim-like bindings)
+- Copy/cut/paste operations with clipboard integration
+- Real-time file system monitoring
+- Configurable external program integration
+- Comprehensive theming with LS_COLORS support
+- Double-click detection for file opening
+- Word-based navigation in text inputs
+
+### External Dependencies
+- ratatui - Terminal UI framework
+- rat-* crates - Additional UI widgets (from git)
+- notify - File system watching
+- cli-clipboard - System clipboard integration
+- open - Opening files with default applications
+- chrono - Date/time handling for file timestamps
+- toml/serde - Configuration serialization
+
+### Development Notes
+- Uses cargo-husky for git pre-commit hooks
+- Logging configured via RUST_LOG environment variable or config file
+- Terminal truecolor detection with 256-color fallback
+- Comprehensive error handling with anyhow
+- Unicode-aware text processing for file names and input
