 ## [Unreleased]
 
+### Added - Animations and Rich UI Enhancements (Spec 005) 🎬✨
+
+This release brings smooth, delightful animations to the A.R.C. CLI while maintaining excellent performance and
+automatic degradation for non-interactive environments.
+
+#### 🎨 Animation System
+
+- **Smart Animation Control**: Animations automatically disabled in CI/CD, pipes, and non-TTY environments
+  - `--no-animation` flag for per-command control
+  - `ARC_NO_ANIMATION` environment variable for persistent settings
+  - Respects `NO_COLOR` standard
+  - Intelligent TTY and terminal width detection
+  - Configurable via `~/.arc/config/animation.yaml`
+
+- **Spring Physics Animations**: Smooth, natural motion using Harmonica library
+  - 60 FPS banner color transitions
+  - Configurable damping and stiffness parameters
+  - Adaptive frame rates for terminal performance
+  - Zero CPU overhead when disabled
+
+- **Animated Banner**: Smooth color transitions on CLI launch
+  - Spring-based color interpolation
+  - Theme-aware gradient animations
+  - Character-by-character rainbow mode
+  - Instant fallback to static rendering
+
+- **Spinner Indicators**: Visual feedback for operations
+  - Bubble Tea integration for smooth animations
+  - Multiple spinner styles (dot, line, dots, etc.)
+  - Automatic display for operations >200ms
+  - Used in `arc info` command
+
+- **Theme Transitions**: Smooth animated theme switching
+  - Color interpolation between themes
+  - Looping preview animations
+  - Waterfall effects for theme lists
+  - Enhanced `arc theme preview` and `arc theme set` commands
+
+#### 🛠️ Developer Features
+
+- **Animation API**: Easy-to-use animation utilities
+  - `animations.ShouldAnimate()` - Centralized animation decision logic
+  - `animations.WithSpinner()` - Wrap operations with spinners
+  - `animations.WithProgress()` - Progress bar wrapper (ready for future use)
+  - `animations.InterpolateColor()` - Smooth color transitions
+  - `animations.AnimateTransition()` - Theme transition helper
+
+- **Configuration System**: Flexible animation settings
+  - `LoadConfig()` with fallback to embedded defaults
+  - Per-animation-type settings (banner, spinner, progress, theme)
+  - FPS, duration, and spring physics tuning
+  - Validation with sensible limits
+
+#### 📝 Documentation
+
+- **User Guide**: Complete animation documentation (`docs/ANIMATIONS.md`)
+  - How to control and disable animations
+  - Configuration options and examples
+  - Troubleshooting guide
+  - Performance characteristics
+
+- **API Reference**: Developer documentation (`docs/api/ANIMATIONS_API.md`)
+  - Complete API reference with examples
+  - Integration patterns with Bubble Tea
+  - Best practices and performance tips
+  - Testing strategies
+
+#### 🎯 Enhanced Commands
+
+- **`arc info`**: Now with animated spinner during data collection
+  - Non-animated fallback when TTY unavailable
+  - Removed debugging delay for instant response
+  - JSON output option for scripting
+
+- **`arc theme set`**: Smooth animated theme transitions
+  - Color interpolation from old to new theme
+  - Visual feedback during switch
+  - Instant mode with `--no-animation`
+
+- **`arc theme preview`**: Animated theme demonstrations
+  - Looping color animations
+  - Character-by-character rainbow effects
+  - Static preview fallback
+
+- **`arc` (root command)**: Animated banner on launch
+  - Smooth gradient color transitions
+  - Spring physics for natural motion
+  - Theme-aware animations
+
+#### ✅ Quality Assurance
+
+- **Comprehensive Testing**: 50+ unit tests, 10 integration tests
+  - `control_test.go`: Animation decision logic (8 tests + benchmark)
+  - `config_test.go`: Configuration loading (10 tests + benchmark)
+  - `spinner_test.go`: Spinner utilities (7 tests + benchmark)
+  - `color_test.go`: Color interpolation (15 tests + 4 benchmarks)
+  - `transition_test.go`: Theme transitions (5 tests + 2 benchmarks)
+  - `progress_test.go`: Progress bars (6 tests + benchmark)
+  - `banner_benchmark_test.go`: Performance benchmarks (6 benchmarks)
+  - Integration tests for E2E validation (10 test cases)
+
+- **Zero Race Conditions**: All tests pass with `-race` flag
+- **Performance Validated**: All benchmarks meet targets
+- **Linting Clean**: Zero golangci-lint warnings
+
+#### 🐛 Bug Fixes
+
+- **Fixed**: TTY detection causing failures in non-interactive environments
+  - Info command now properly falls back to non-animated mode
+  - No more `/dev/tty: device not configured` errors in tests
+- **Fixed**: Removed debugging delay (500ms) from info command
+- **Fixed**: Animation cleanup on Ctrl+C interruption
+
+#### 🔧 Technical Improvements
+
+- **Performance**: <1% CPU usage during animations
+- **Memory**: Efficient buffer reuse in animation loops
+- **Compatibility**: Graceful degradation across all terminal types
+- **Reliability**: Context-aware cancellation for clean shutdown
+
+---
+
 ### Added - Interactive UI Enhancements (Spec 018) 🎨✨
 
 This major release transforms the CLI into a modern, interactive experience with smooth animations, comprehensive
