+# Terminal Interactive Input Feature
+
+## Overview
+Implement clean terminal handoff for interactive input collection, allowing users to see cursor and real-time character input while maintaining spinner functionality.
+
+## Problem Statement
+Current implementation has terminal control conflicts between Rich Live (spinner) and input collection systems, resulting in poor UX where users can't see their cursor or characters appearing in real-time.
+
+## Solution
+Complete terminal handoff approach - pause Rich Live display during input collection, resume after completion.
+
+## Implementation Tasks
+
+### Core Components
+- [x] **Terminal State Management** - Enhanced existing input state module
+- [x] **Spinner Pause/Resume** - Added pause/resume capability to progress_spinner
+- [x] **Clean Input Collection** - Ensured input system gets exclusive terminal control
+- [x] **State Coordination** - Coordinated between spinner and input systems
+
+### Implementation Checklist
+
+#### Phase 1: Enhanced Progress Spinner

+# TUI Refactoring Feature: Unified Input Collection System
+
+## Overview
+Refactor terminal user interface (TUI) input collection to create a unified, consistent system across CLI prompt commands and interactive workflows. Both systems will use the same terminal handoff functionality while maintaining backward compatibility.
+
+## Problem Statement
+Currently, two separate input collection systems exist:
+- `src/elf0/functions/utils.py:126-215` - Has terminal handoff integration ✅
+- `src/elf0/cli.py:529-581` - Missing terminal handoff integration ❌
+
+This causes users to experience cursor visibility issues and inconsistent behaviour between CLI prompt mode and interactive workflows.
+
+## Solution Architecture
+Create a shared core input collection module with wrapper functions that maintain existing APIs while providing unified terminal handoff functionality.
+
+## Implementation Tasks
+
+### Phase 1: Core Input Collection Module
+
+#### Create New Module File
+- [x] Create `src/elf0/core/input_collector.py` with file location comment
+- [x] Add necessary imports: `sys`, `time`, `prompt_toolkit`, `rich.console`, `elf0.core.input_state`, `elf0.core.compiler`
+- [x] Add module-level docstring explaining unified input collection purpose
+
+#### Define Exception Handling
+- [x] Create `InputCollectionError` exception class for input collection failures
+- [x] Add appropriate docstring explaining when this exception is raised
+
+#### Implement Core Input Collection Function
+- [x] Create `collect_terminal_input(prompt: str, multiline: bool = True) -> str` function
+- [x] Add comprehensive docstring with parameters, return value, and usage examples
+- [x] Implement terminal handoff signaling with `set_collecting_input()`
+- [x] Add `time.sleep(0.2)` delay for spinner handoff coordination
+- [x] Implement Rich console prompt display with proper formatting
+- [x] Add terminal detection logic (`sys.stdin.isatty()`)
+- [x] Implement retry logic with fallback mechanisms (max 3 retries)
+- [x] Add exit command detection and handling (`/exit`, `/quit`, `/bye`)
+- [x] Implement processing feedback display
+- [x] Ensure `clear_collecting_input()` is called in finally block
+- [x] Add proper error handling for KeyboardInterrupt and EOFError
+
+#### Implement Enhanced Input Collection Helper
+- [x] Create `_collect_enhanced_input()` function for terminal input with multi-line support
+- [x] Use `prompt_toolkit.PromptSession` with history and lexer configuration
+- [x] Implement submission logic (double-enter, `/send` command)
+- [x] Add proper line collection and joining logic
+
+#### Implement Simple Input Collection Helper
+- [x] Create `_collect_simple_input()` function for non-terminal input
+- [x] Use standard `input()` function with proper buffering
+- [x] Add EOFError handling for graceful degradation
+
+### Phase 2: Wrapper Functions
+
+#### Create CLI Wrapper
+- [x] Implement `get_cli_input() -> str` function
+- [x] Add docstring explaining CLI-specific usage
+- [x] Call `collect_terminal_input()` with appropriate parameters
+- [x] Return raw string result for CLI compatibility
+- [x] Add proper error handling and user feedback
+
+#### Create Workflow Wrapper
+- [x] Implement `get_workflow_input(state: WorkflowState, prompt: str) -> WorkflowState` function
+- [x] Add docstring explaining workflow-specific usage and state handling
+- [x] Extract prompt from state if default prompt provided
+- [x] Call `collect_terminal_input()` with appropriate parameters
+- [x] Handle exit commands and return appropriate WorkflowState with exit flag
+- [x] Wrap result in WorkflowState format with proper keys
+- [x] Add error handling that returns appropriate error state
+
+### Phase 3: Refactor Existing Functions
+
+#### Update Utils Module
+- [x] Read current `src/elf0/functions/utils.py` to understand existing implementation
+- [x] Import `get_workflow_input` from `elf0.core.input_collector`
+- [x] Replace `get_user_input()` function implementation (lines 126-215)
+- [x] Maintain exact same function signature: `get_user_input(state: WorkflowState, prompt: str = "Please provide input:") -> WorkflowState`
+- [x] Call `get_workflow_input(state, prompt)` and return result
+- [x] Remove now-unused helper functions: `_collect_enhanced_input`, `_collect_simple_input`, `_show_processing_feedback`, `_show_exit_feedback`
+- [x] Keep `_is_exit_command` and `_create_exit_state` functions as they may be used elsewhere
+- [x] Verify all imports are still needed and remove unused ones
+
+#### Update CLI Module
+- [x] Read current `src/elf0/cli.py` to understand existing implementation
+- [x] Import `get_cli_input` from `elf0.core.input_collector`
+- [x] Replace `get_multiline_input()` function implementation (lines 529-581)
+- [x] Maintain exact same function signature: `get_multiline_input() -> str`
+- [x] Keep introductory Rich console messages for user guidance
+- [x] Call `get_cli_input()` and return result
+- [x] Ensure proper error handling and user feedback
+
+### Phase 4: Testing and Validation
+
+#### Unit Testing
+- [x] Test `collect_terminal_input()` function with various prompt inputs
+- [x] Test `get_cli_input()` wrapper returns correct string format
+- [x] Test `get_workflow_input()` wrapper returns correct WorkflowState format
+- [x] Test error handling scenarios (KeyboardInterrupt, EOFError, Exception)
+- [x] Test exit command detection and handling
+- [x] Test retry logic and fallback mechanisms
+- [x] Test terminal vs non-terminal input collection paths
+
+#### Integration Testing
+- [ ] Test CLI prompt command: `uv run elf0 prompt <workflow.yaml>`
+- [ ] Verify cursor visibility during CLI prompt input collection
+- [ ] Verify real-time character display during CLI prompt input
+- [ ] Test interactive workflows continue working: `uv run elf0 agent <workflow.yaml> --prompt "test"`
+- [ ] Verify spinner pause/resume behavior during both CLI and workflow input
+- [ ] Test exit commands work in both CLI and workflow modes
+- [ ] Test multi-line input functionality in both modes
+
+#### User Experience Testing

+- [ ] Test exit commands (`/exit`, `/quit`, `/bye`) in both modes
+- [ ] Test error scenarios and graceful degradation
+- [ ] Test processing feedback display consistency
+- [ ] Verify no regression in existing functionality
+
+### Phase 5: Code Quality and Documentation
