# T7-33: CLI Task View Management Commands

**Priority**: Medium
**Status**: Completed
**Phase**: 7 (CLI Enhancement)
**Estimated Effort**: 3-4 hours

## Description

Implement CLI commands for managing saved task views (filters). The backend API for task views is fully implemented (`/v1/workspaces/{workspace_id}/task-views`), but CLI commands are missing. This task adds the `anyt view` command group to provide full CRUD operations for saved filters.

**Note**: Task views are user-scoped features. Agent authentication is not supported.

## Objectives

- Implement `anyt view` command group
- Provide create, list, show, edit, and delete operations
- Support saving commonly used filters
- Support default view selection
- Ensure proper user authentication (JWT only)
- Support both interactive and JSON output modes

## Acceptance Criteria

- [ ] `anyt view create <name>` - Create a new saved view
  - Support filter options: `--status`, `--priority`, `--owner`, `--labels`
  - Support `--default` flag to set as default view
  - Support `--order` flag for custom ordering
  - Output created view details
- [ ] `anyt view list` - List all saved views
  - Display in table format
  - Highlight default view
  - Show filter summary for each view
  - Support `--json` output
- [ ] `anyt view show <name>` - Show view details
  - Display filter configuration
  - Show task count matching filter
  - Support `--json` output
- [ ] `anyt view apply <name>` - Apply a saved view (list tasks)
  - Execute the saved filter
  - Display results in table format
  - Support all standard task list options
  - Support `--json` output
- [ ] `anyt view edit <name>` - Edit view properties
  - Support updating filters, name, default status
  - Show before/after comparison
  - Support `--json` output
- [ ] `anyt view rm <name>` - Delete a saved view
  - Require confirmation for default view
  - Support `--force` flag
  - Support bulk deletion
- [ ] `anyt view default <name>` - Set/unset default view
  - Support `--clear` to remove default
  - Show confirmation message
- [ ] All commands support `--json` flag for machine-readable output
- [ ] All commands respect workspace context (`.anyt/anyt.json`)
- [ ] Error handling for agent authentication attempts
- [ ] Update `docs/CLI_USAGE.md` with new commands section

## Dependencies

- Backend Task View API (already implemented)
- CLI client configuration and workspace detection
- User JWT authentication (not agent keys)

## Technical Notes

### File Structure
```
src/cli/commands/view.py  # New file for task view commands
```

### Command Group Structure
```python
# src/cli/commands/view.py
import typer
from typing import Optional, List
from rich.console import Console
from rich.table import Table

app = typer.Typer(help="Manage saved task views (filters)")

@app.command("create")
async def create_view(
    name: str,
    status: Optional[str] = typer.Option(None, "--status", help="Filter by status (comma-separated)"),
    priority_min: Optional[int] = typer.Option(None, "--priority-min", help="Minimum priority"),
    priority_max: Optional[int] = typer.Option(None, "--priority-max", help="Maximum priority"),
    owner: Optional[str] = typer.Option(None, "--owner", help="Filter by owner"),
    labels: Optional[str] = typer.Option(None, "--labels", help="Filter by labels (comma-separated)"),
    default: bool = typer.Option(False, "--default", help="Set as default view"),
    json_output: bool = typer.Option(False, "--json", help="Output in JSON format"),
):
    """Create a new saved task view (filter)."""
    # Build filters dict from options
    # Call API to create view
    # Display result

@app.command("list")
async def list_views(
    json_output: bool = typer.Option(False, "--json", help="Output in JSON format"),
):
    """List all saved task views."""
    # Implementation with rich table
    # Highlight default view with ⭐

@app.command("show")
async def show_view(
    name: str,
    json_output: bool = typer.Option(False, "--json", help="Output in JSON format"),
):
    """Show details for a specific view."""
    # Display filter configuration

):
    """Set or clear the default task view."""
    # Implementation
```

### Register in main.py
```python
# src/cli/main.py
from cli.commands import view as view_commands

app.add_typer(view_commands.app, name="view")
```

### API Client Methods
Add to `src/cli/client.py`:
```python
async def create_task_view(self, workspace_id: int, user_id: str, name: str, filters: dict, is_default: bool = False):
    """Create a new saved task view."""
    # POST /v1/workspaces/{workspace_id}/task-views

async def list_task_views(self, workspace_id: int):
    """List all task views for current user."""
    # GET /v1/workspaces/{workspace_id}/task-views

async def get_task_view(self, workspace_id: int, view_id: int):
    """Get task view by ID."""
    # GET /v1/workspaces/{workspace_id}/task-views/{view_id}

async def get_default_view(self, workspace_id: int):
    """Get user's default task view."""
    # GET /v1/workspaces/{workspace_id}/task-views/default

async def update_task_view(self, workspace_id: int, view_id: int, **updates):
    """Update task view properties."""
    # PATCH /v1/workspaces/{workspace_id}/task-views/{view_id}

async def delete_task_view(self, workspace_id: int, view_id: int):
    """Delete a task view."""
    # DELETE /v1/workspaces/{workspace_id}/task-views/{view_id}
```

### Example Usage
```bash
# Create views
anyt view create "My High Priority" --status "todo,inprogress" --priority-min 1 --default
anyt view create "Bugs Only" --labels "bug"
anyt view create "Team Tasks" --owner "me" --status "inprogress"

# List all views (shows ⭐ for default)
anyt view list

# Apply a view
anyt view apply "My High Priority"

# Show view details
anyt view show "Bugs Only"

# Edit view
anyt view edit "My High Priority" --priority-min 2

# Set as default
anyt view default "Bugs Only"

# Clear default
anyt view default --clear

# Delete view
anyt view rm "Old View" --force
```

### Filter Structure
Views save filter configurations like:
```json
{
  "filters": {
    "status": ["todo", "inprogress"],
    "priority_min": 1,
    "priority_max": 2,
    "owner_ids": ["user-123"],
    "labels": ["bug", "urgent"],
    "labels_logic": "AND"
  }
}
```

## Documentation Updates Required

After implementation, update the following documentation:

### 1. docs/CLI_USAGE.md
Add new section after "Label Management":

```markdown
### Task Views (Saved Filters)

Save and manage commonly used task filters.

**Note**: Task views are user-specific and require user authentication (not available for agents).

#### Create View
\`\`\`bash
anyt view create <name> [OPTIONS]
\`\`\`

**Options:**
- `--status` - Filter by status (comma-separated)
- `--priority-min` - Minimum priority
- `--priority-max` - Maximum priority
- `--owner` - Filter by owner
- `--labels` - Filter by labels (comma-separated)
- `--default` - Set as default view
- `--json` - JSON output

#### List Views
\`\`\`bash
anyt view list [--json]
\`\`\`

#### Show View
\`\`\`bash
anyt view show <name> [--json]
\`\`\`

#### Apply View
\`\`\`bash
anyt view apply <name> [--limit N] [--json]
\`\`\`

#### Edit View
\`\`\`bash
anyt view edit <name> [OPTIONS]
\`\`\`

#### Delete View
\`\`\`bash
anyt view rm <names>... [--force] [--json]
\`\`\`

#### Set Default View
\`\`\`bash
anyt view default <name>
anyt view default --clear  # Remove default
\`\`\`

**Examples:**
\`\`\`bash
# Create saved views
anyt view create "High Priority" --status "todo,inprogress" --priority-min 1 --default
anyt view create "My Bugs" --labels "bug" --owner "me"

# List all views
anyt view list

# Apply a view
anyt view apply "High Priority"

# Edit view
anyt view edit "High Priority" --priority-min 2

# Set/clear default
anyt view default "My Bugs"
anyt view default --clear
\`\`\`
```
