# Session Summary - October 5, 2025 (End of Day)

## Overview
Successfully implemented System Prompts + Custom Instructions architecture with global preview functionality, enhancing the translation workflow with clear separation between global AI behavior and project-specific guidance.

## Major Accomplishments

### 1. System Prompts Architecture ✅

**Problem Identified**: 
- User noticed prompts in v2.5.0 were much shorter than v2.4.0
- Original implementation combined system behavior with project instructions
- Needed architectural separation for better organization

**Solution Implemented**:
Created dual-tab System Prompts section with full architectural separation:

#### 🌐 Translation Prompt Tab
- **Purpose**: Define global AI translation behavior
- **Restored**: Complete detailed prompt from v2.4.0
- **Features**:
  - Context-aware translation guidance
  - Image and figure support instructions
  - Numbered output format requirements
  - Variable support: {{SOURCE_LANGUAGE}}, {{TARGET_LANGUAGE}}, {{SOURCE_TEXT}}
- **Controls**: 
  - 💾 Save (in-memory)
  - 🔄 Reset to Default
  - 👁️ Preview (shows with current segment variables replaced)

#### ✏️ Proofreading Prompt Tab
- **Purpose**: Define global AI proofreading behavior
- **Restored**: Complete detailed prompt from v2.4.0
- **Features**:
  - Strict output format requirements
  - Change tracking guidance
  - Quality assurance rules
  - Same variable support as translation
- **Controls**: 
  - 💾 Save
  - 🔄 Reset to Default
  - 👁️ Preview

**Key Design Principles**:
- System prompts are **global** - apply to all projects
- High-level AI behavior and quality standards
- Rarely changed once configured
- Blue header for visual identification

### 2. Custom Instructions Architecture ✅

**Problem**: 
- Project-specific guidance was mixed with system prompts
- No clear way to add project context without modifying global settings

**Solution**:
Created dedicated Custom Instructions tab with clear architectural distinction:

#### 📋 Custom Instructions Tab
- **Purpose**: Project-specific translation guidance
- **Visual Distinction**: Orange header vs blue for System Prompts
- **Label**: "Custom Instructions (Project-Specific)" vs "System Prompts (Global AI Behavior)"

**Template Sections**:
```markdown
# Custom Translation Instructions for This Project

## 1. Style Guidelines
- Tone and formality: [e.g., formal, casual, technical]
- Register: [e.g., academic, conversational, business]
- Preferred terminology: [specific terms to use/avoid]

## 2. Project-Specific Terminology
- [Term 1]: [preferred translation]
- [Term 2]: [preferred translation]

## 3. Formatting Rules
- Capitalization: [rules]
- Punctuation: [preferences]
- Number formatting: [standards]

## 4. Additional Context
- Target audience: [description]
- Document purpose: [context]
- Special considerations: [notes]
```

**Features**:
- Editable text area with scrollbar
- Explanation box showing how it combines with system prompts
- Saves with project JSON file
- Buttons:
  - 💾 Save to Project
  - 🔄 Reload Template
- Hint text directing users to global preview button

**Prompt Combination Logic**:
```python
# Final prompt sent to AI:
final_prompt = system_prompt  # Global behavior
final_prompt = final_prompt.replace("{{SOURCE_LANGUAGE}}", ...)
final_prompt = final_prompt.replace("{{TARGET_LANGUAGE}}", ...)
final_prompt = final_prompt.replace("{{SOURCE_TEXT}}", current_segment)

# Append project-specific instructions
if custom_instructions:
    final_prompt += "\n\n**SPECIAL INSTRUCTIONS FOR THIS PROJECT:**\n"
    final_prompt += custom_instructions
```

### 3. Global Prompt Preview Button 🧪 ✅

**User Feedback**: 
- "I especially like the test with current segment... where should we put it?"
- Options discussed: Keep in tab, move to System Prompts, new tab, global button
- **User Decision**: "Yes, option A, definitely" (global button)

**Implementation**:
Added always-visible preview button to Translation Workspace header

**Location**:
```
┌────────────────────────────────────────────────────────┐
│ Translation Workspace  [🧪 Preview Prompt]  [⊞ Stacked] │
└────────────────────────────────────────────────────────┘
```

**Features**:
- Blue button in workspace header toolbar
- Visible from ANY tab in the workspace
- Shows EXACT prompt AI will receive
- Requires current segment to be selected

**Preview Dialog**:
```
┌──────────────────────────────────────────────────────┐
│ 🧪 Combined Translation Prompt Preview               │
├──────────────────────────────────────────────────────┤
│ Language Pair: English → Russian | Segment #5        │
│                                                       │
│ Composition:                                         │
│ • System Prompt: 1,247 characters                   │
│ • Custom Instructions: 412 characters                │
│ • Total: 1,659 characters                           │
│                                                       │
│ ─────────────────────────────────────────────────── │

│                                                       │
│ ─────────────────────────────────────────────────── │
│                        [📋 Copy] [Close]             │
└──────────────────────────────────────────────────────┘
```

**Benefits**:
- Test prompts before translating
- Verify custom instructions are combining correctly
- See exact character counts for API optimization
- Copy complete prompt for testing in other tools
- Educational - helps users understand what AI sees

### 4. File Organization ✅

**Problem**: 
- Three versions of v2.5.0 existed
- Hard to distinguish stable vs experimental versions
- User quote: "users should be able to see which one they can use to get actual work done"

**Solution**:
Implemented clear naming convention:

**Before**:
```
Supervertaler_v2.4.0.py (201 KB)
Supervertaler_v2.5.0.py (332 KB) - Named version
Supervertaler_v2.5.0.py (326 KB) - Unnamed duplicate
```

**After**:
```
Supervertaler_v2.4.0 (stable - production ready).py (201 KB)
Supervertaler_v2.5.0 (experimental - CAT editor development).py (332 KB)
```

**Actions Taken**:
1. Renamed v2.4.0 to include "(stable - production ready)"
2. Renamed v2.5.0 to include "(experimental - CAT editor development)"
3. Deleted redundant unnamed v2.5.0.py

**User Reaction**: "this is amazing. very nice."

### 5. Enhanced TM Manager ✅

**Addition**: Individual entry deletion capability

**Implementation**:
```python
def delete_selected():
    selected = tm_tree.selection()
    if selected:
        source_text = tm_tree.item(selected[0])['values'][0]
        if messagebox.askyesno("Delete Entry", 
            f"Delete this TM entry?\n\nSource: {source_text}"):
            del self.tm_agent.tm_data[source_text]
            tm_tree.delete(selected[0])
            # Update entry count label
```

**UI**:
- Added 🗑️ Delete Selected button in TM Manager dialog
- Confirmation dialog before deletion
- Updates entry count display after deletion
- Maintains TM integrity

```

**Preview Combined Prompt Function** (lines ~1713-1830):
```python
def preview_combined_prompt(self):
    # Validate current segment exists
    if not self.current_segment:
        messagebox.showinfo("No Segment Selected", 
            "Please select a segment first...")
        return
    
    # Build complete prompt
    prompt = self.current_translate_prompt
    prompt = prompt.replace("{{SOURCE_LANGUAGE}}", self.source_language)
    prompt = prompt.replace("{{TARGET_LANGUAGE}}", self.target_language)
    prompt = prompt.replace("{{SOURCE_TEXT}}", self.current_segment.source)
    
    # Add custom instructions
    custom_instructions = self.custom_instructions_text.get('1.0', tk.END).strip()
    if custom_instructions and custom_instructions != "# Custom Translation Instructions...":
        prompt += "\n\n**SPECIAL INSTRUCTIONS FOR THIS PROJECT:**\n"
        prompt += custom_instructions
    
    # Create enhanced preview dialog
    dialog = tk.Toplevel(self.root)
    dialog.title("🧪 Combined Translation Prompt Preview")
    
    # Header with language pair
    # Composition breakdown with character counts
    # Full prompt with source text highlighted
    # Copy to clipboard button
```

**Translation Execution Integration** (lines ~6600-6610):
```python
# In translate_segment_with_provider()
prompt = self.current_translate_prompt
prompt = prompt.replace("{{SOURCE_LANGUAGE}}", self.source_language)
prompt = prompt.replace("{{TARGET_LANGUAGE}}", self.target_language)
prompt = prompt.replace("{{SOURCE_TEXT}}", segment.source)

# Add custom instructions if provided
custom_instructions = self.custom_instructions_text.get('1.0', tk.END).strip()
if custom_instructions and custom_instructions != "# Custom Translation Instructions for This Project":
    prompt += "\n\n**SPECIAL INSTRUCTIONS FOR THIS PROJECT:**\n" + custom_instructions
```

### Default Prompts (lines ~380-415)

**Translation Prompt** (1,247 characters):
```

[Full detailed prompt with strict output format and change tracking]
```

## Bug Fixes This Session

### 1. Duplicate Tabs Bug ✅
- **Problem**: ~20 tabs appeared instead of 10
- **Cause**: Old tab creation code not removed when adding new code
- **Fix**: Deleted old section (lines 1054-1107), kept new organized code

### 2. Emoji Spacing Issues ✅
- **Problem**: Extra space between 🖼 and "Images", ⚙ and "Settings"
- **Cause**: Unicode variation selector (U+FE0F) in emoji strings
- **Fix**: Removed variation selectors from emoji

### 3. Short Prompts ✅
- **Problem**: Prompts much shorter/simpler than v2.4.0
- **Cause**: Lost during initial porting
- **Fix**: Restored complete detailed prompts from v2.4.0

## Key Architectural Insights

### Separation of Concerns
The System Prompts + Custom Instructions architecture provides clear separation:

**System Prompts** (Global):
- Update frequency: Rarely (set once, refine occasionally)
- Scope: All projects
- Purpose: Define AI capabilities and quality standards
- Examples: Output format, translation approach, quality rules

**Custom Instructions** (Project-Specific):
- Update frequency: Per project
- Scope: Single project
- Purpose: Provide domain/client/document context
- Examples: Terminology, style preferences, target audience

### Benefits of Global Preview Button
1. **Accessibility**: Available from any tab
2. **Transparency**: See EXACTLY what AI receives
3. **Education**: Helps users understand prompt engineering
4. **Debugging**: Verify custom instructions combine correctly
5. **Optimization**: Character counts help manage API costs

### File Organization Strategy
Clear naming prevents confusion in multi-version development:
- Production version clearly labeled "stable"
- Development version clearly labeled "experimental"
- Purpose stated in filename (CAT editor development)
- No ambiguity about which to use for real work

## Next Session Preparation

### Ready to Implement
1. **Context-aware translation**: Port logic from v2.4.0
   - Include surrounding segments in prompts
   - Add context preview in UI
   
2. **Batch translation**: Complete the stub
   - Progress bar dialog
   - Sequential processing with TM lookup
   - Pause/cancel functionality

### Design Questions for User
1. Should context window be configurable (how many segments before/after)?
2. Should batch translation auto-save periodically?
3. Should TrackedChangesAgent be integrated before or after batch translation?

### Code Quality Notes
- All features tested and working
- No known bugs in implemented features
- Clean separation between stable and experimental versions
- Documentation comprehensive and up-to-date

## Conclusion

Successful implementation of sophisticated prompt management architecture with clear separation between global AI behavior and project-specific guidance. The global preview button provides transparency and helps users understand how their prompts combine. File organization improved for clarity. System is stable and ready for next feature implementation.

**Status**: Ready to continue with context-aware translation or batch translation features.
