# Tool Call Processing and Real-time Feedback Enhancement

## Issue Summary
The current tool call processing system requires complete tool call construction before any output is displayed, leading to poor user experience during long-running operations. Additionally, there's no real-time feedback on processing rates or progress metrics.

## Problem Description

### Current Behavior:
1. **Complete Tool Call Required**: Users must finish typing the entire tool call before any output appears
2. **No Incremental Feedback**: During long operations (like large file writes), users see no progress indicators
3. **No Performance Metrics**: No information about tokens per second, bytes processed, or operation speed
4. **Freezing Experience**: Long-running operations freeze the UI until completion

### Expected Behavior:
1. **Immediate Output**: Partial results should appear as soon as available
2. **Real-time Metrics**: Display processing rates (tokens/second, bytes/second)
3. **Progress Indicators**: Show completion percentage or estimated time remaining
4. **Responsive Interface**: UI remains interactive throughout long operations

## Specific Issues Identified

### 1. Tool Call Construction Freezing
- When writing `write_file` commands with large content, the entire command must be typed before any response appears
- This creates an unintuitive user experience where users don't know if their input is being processed

### 2. Missing Performance Monitoring
- No indication of processing speed (tokens/second for text operations)
- No byte rate monitoring for file operations
- No way to estimate completion time for large tasks

### 3. Lack of Intermediate Feedback
- Long-running operations provide no intermediate status updates
- Users cannot tell if a process is stuck, progressing normally, or encountering issues

## User Experience Impact
- **Uncertainty**: Users can't determine if their commands are working
- **Frustration**: Waiting for long operations without feedback
- **Debugging Difficulty**: No way to monitor progress or performance
- **Resource Management**: Cannot make informed decisions about task duration

## Suggested Solutions

### 1. Streaming Output Implementation
```
// Example of desired behavior during write_file:
write_file: [50%] Writing 1000/2000 lines...
write_file: [75%] Writing 1500/2000 lines...
write_file: [100%] Complete - 2000 lines written
```

### 2. Real-time Rate Monitoring
```
write_file: Processing at 1500 tokens/sec
write_file: Writing at 2.3 MB/sec
```

### 3. Progressive Tool Call Execution
- Allow partial tool call execution with immediate feedback
- Show "processing..." status while waiting for full input
- Enable early output display even when command is incomplete

### 4. Debug Mode Toggle
- Add a debug mode that shows all intermediate steps
- Display token/buffer counts during processing
- Show memory usage and processing times

## Test Cases
1. **Small Write Operation**: Should show immediate completion with basic metrics
2. **Medium Write Operation**: Should show incremental progress and rate metrics
3. **Large Write Operation**: Should show detailed progress, rate, and estimated time
4. **Tool Call Construction**: Should allow immediate feedback during typing

## Priority
High - This impacts core usability and makes long-running operations frustrating and unpredictable
