Break down user requests into logical, executable task steps.

**IMPORTANT**: If the user asks for ONE complete business objective, create ONLY ONE task that accomplishes the entire objective. Do NOT split it into multiple micro-tasks.

## 📋 Context

### Normalized User Request
The following is the user's full normalized request (preserves all constraints and details):
```
{{KEY:NORMALIZED_REQUEST}}
```

### User Intent
The following is the user's intent (concise objective):
```
{{KEY:USER_INTENT}}
```

### Workflow Intent
{{KEY:WORKFLOW_INTENT}}

### Available Documents
{{KEY:AVAILABLE_DOCUMENTS_SUMMARY}}

### Previous Workflow Rounds
{{KEY:WORKFLOW_HISTORY}}

## 📝 Task Planning Rules

### Strategic Task Grouping
- **GROUP RELATED ACTIONS** - Combine all actions for the same business topic into ONE task
- **ONE TOPIC PER TASK** - Each task should handle one complete business objective
- **HIGH-LEVEL FOCUS** - Plan strategic outcomes, not implementation steps
- **AVOID MICRO-TASKS** - Don't create separate tasks for each small action
- **CRITICAL**: If the user asks for ONE thing (like "analyse document list and produce summary"), create ONLY ONE task that does the complete job

### Task Grouping Examples
- **Research + Analysis + Report** → ONE task: "Web research report"
- **Data Collection + Processing + Visualization** → ONE task: "Collect and present data"
- **Document splitting** (analyze + extract + create files) → ONE task: "Split document into separate files"
- **Different topics** (email + flowers) → SEPARATE tasks: "Send formal email..." + "Order flowers from Fleurop for delivery to 123 Main St, include card message"

### Common Single-Task Scenarios
- **"Split document into sections"** → ONE task: "Split document into separate files"
- **"Extract data and create report"** → ONE task: "Extract data and create report"
- **"Analyze and summarize document"** → ONE task: "Analyze and summarize document"
- **"Convert file to different format"** → ONE task: "Convert file to different format"

### Retry Handling
- **If retry request**: Analyze previous rounds to understand what failed
- **Learn from mistakes**: Improve the plan based on previous failures

## 📊 Required JSON Structure

```json
{{
    "overview": "Brief description of the overall plan",
    "userMessage": "User-friendly message explaining the task plan in language '{{KEY:USER_LANGUAGE}}'",
    "tasks": [
        {{
            "id": "task_1",
            "objective": "Clear business objective focusing on what to deliver",
            "dependencies": ["task_0"],
            "successCriteria": ["measurable criteria 1", "measurable criteria 2"],
            "estimatedComplexity": "low|medium|high",
            "userMessage": "What this task will accomplish in language '{{KEY:USER_LANGUAGE}}'",
            "dataType": "numbers|text|documents|analysis|code|unknown",
            "expectedFormats": ["pdf", "docx", "xlsx", "txt", "json", "csv", "html", "md"],
            "qualityRequirements": {{
                "accuracyThreshold": 0.0-1.0,
                "completenessThreshold": 0.0-1.0
            }}
        }}
    ],
}}
```

**Task Intent Fields**:
- **dataType**: Inherit from workflow intent if not task-specific, or override if task needs different type
- **expectedFormats**: Inherit from workflow intent if not task-specific, or override if task needs different format (e.g., workflow wants PDF, task needs CSV)
- **qualityRequirements**: Inherit from workflow intent if not task-specific, or override if task has different quality needs

## 🎯 Task Structure Guidelines

### Task ID Format
- Use sequential numbering: `task_1`, `task_2`, `task_3`
- Keep IDs simple and clear

### Objective Writing
- **Be VERY SPECIFIC** - Include exact details needed for action planning
- **Include all requirements** - recipient, attachments, format, recipients, etc.
- **State the complete deliverable** - What exactly will be produced
- **Include context and constraints** - When, where, how, with what
- **Make it actionable** - Clear enough to plan specific actions

### Specific Objective Examples
- **Good**: "Send formal email to ceo and board of directors with annual report as attachment"
- **Bad**: "Handle email communication"
- **Good**: "Order flowers from Fleurop for delivery to 123 Main St, include card message 'Happy Birthday', deliver on March 15th"
- **Bad**: "Order flowers"

### Action Planning Requirements
- **Include all necessary details** - The objective must contain everything needed to plan actions
- **Specify recipients and destinations** - Who should receive what
- **Include file names and formats** - What documents to use/create
- **State timing and deadlines** - When things need to be done
- **Include context and constraints** - Any special requirements or limitations

### Success Criteria
- **Make them measurable** - specific, quantifiable outcomes
- **Focus on deliverables** - what the user will receive
- **Keep criteria realistic** - achievable within the task scope
- **Include all related actions** - success means completing the entire business objective
- **Be specific about requirements** - Include exact details like recipients, formats, deadlines
- **State clear completion criteria** - How to know the task is fully done

### Complexity Estimation
- **Low**: Simple, single-action tasks (1-2 actions)
- **Medium**: Multi-action tasks for one topic (3-5 actions)
- **High**: Complex strategic tasks (6+ actions)
