# task-list

**Category**: Task Management

## Usage

```bash
task-list [--dir <directory>] [--status <status>] [--format <format>]
```

## Arguments

- `--dir`: Optional - Specific directory (focus, active, paused, completed, all). Default: all
- `--status`: Optional - Filter by status (pending, in_progress, completed, blocked)
- `--format`: Optional - Output format (table, list, json). Default: table

## Execution Instructions for Claude Code

When this command is run, Claude Code should:

1. Scan specified directories for task files (*.md)
2. Parse each task file header to extract:
   - Task ID and title
   - Status and priority
   - Progress percentage
   - Estimated/actual hours
   - Blocked status
   - Dependencies
3. Apply any filters (status, etc.)
4. Calculate aggregate statistics
5. Display in requested format

## Directory Scanning Order

1. **focus/** - Show first (current work)
2. **active/** - Ready tasks
3. **paused/** - Context switched
4. **completed/** - Recently done
5. **archive/** - If requested

## Output Formats

### JSON Format
```json
{
  "summary": {
    "total_tasks": 5,
    "in_progress": 2,
    "blocked": 1,
    "total_estimated_hours": 40,
    "total_actual_hours": 9
  },
  "tasks": {
    "focus": [...],
    "active": [...],
    "paused": [...],
    "completed": [...]
  }
}
```

## Progress Indicators

- `████████░░` - Visual progress bar
- Percentage with color coding:
  - 0-25%: 🔴 Red
  - 26-75%: 🟡 Yellow
  - 76-100%: 🟢 Green

## Error Handling

- If no tasks found: Show helpful message about creating tasks
- If task file corrupted: Mark with ❌ and continue
- If no task directories: Suggest running `task-system-init`

## Example

```bash
# List all tasks
task-list

# Show only focused task
task-list --dir focus

# Show all in-progress tasks
task-list --status in_progress

# Get JSON for automation
task-list --format json > tasks.json

# Show only active directory in list format
task-list --dir active --format list
```

## Implementation Tips for Claude Code

1. **Efficient Parsing**: Cache parsed headers for performance
2. **Smart Sorting**: Focus first, then by priority and progress
3. **Dependency Tracking**: Show dependency chains if relevant
4. **Time Calculations**: Sum estimates and actuals by directory
5. **Visual Appeal**: Use Unicode characters for better formatting
