## Standard Workflows

### 1. Creating a New CLI Command

**When:** Adding new functionality to the CLI

**Steps:**

1. Design command syntax and arguments

2. Implement command handler function

3. Add argument parsing and validation

4. Implement core logic

5. Add progress feedback

6. Write help text and examples

7. Add error handling

8. Write tests for command

9. Update CLI documentation

**Example:**

```python

import click

from rich.console import Console

from rich.progress import Progress, SpinnerColumn, TextColumn

console = Console()

@click.command()

@click.argument('project_name')

@click.option('--template', '-t', type=click.Choice(['minimal', 'standard', 'full']),

default='standard', help='Project template to use')

@click.option('--framework', '-f', help='Backend framework (e.g., fastapi, django)')

@click.option('--dry-run', is_flag=True, help='Show what would be created without creating')

def init(project_name: str, template: str, framework: str, dry_run: bool):

"""

Initialize a new project with NXTG-Forge.

Examples:

forge init my-project

forge init my-api --framework fastapi --template minimal

forge init --dry-run my-app

"""

console.print(f"[bold cyan]Initializing project: {project_name}[/bold cyan]\n")

# Validate inputs

if not project_name.replace('-', '').replace('_', '').isalnum():

console.print("[red]Error: Project name must be alphanumeric[/red]")

raise click.Abort()

with Progress(

SpinnerColumn(),

TextColumn("[progress.description]{task.description}"),

console=console

) as progress:

task = progress.add_task("Creating project structure...", total=5)

# Create directories

create_directories(project_name, dry_run)

progress.advance(task)

# Generate files

generate_files(project_name, template, framework, dry_run)

progress.advance(task)

# Initialize git

init_git(project_name, dry_run)

progress.advance(task)

# Configure MCP servers

configure_mcp(project_name, dry_run)

progress.advance(task)

# Create initial state

create_state(project_name, dry_run)

progress.advance(task)

console.print(f"\n[green]✓[/green] Project '{project_name}' initialized successfully!")

console.print(f"\nNext steps:")

console.print(f" cd {project_name}")

console.print(f" forge status")

```

### 2. Interactive Wizard

**When:** Complex setup requiring multiple inputs

**Steps:**

1. Define wizard flow

2. Create questions with validation

3. Collect user responses

4. Show summary for confirmation

5. Execute based on responses

**Example:**

```python

import questionary

from questionary import Style

custom_style = Style([

('qmark', 'fg:#673ab7 bold'),

('question', 'bold'),

('answer', 'fg:#2196f3 bold'),

('pointer', 'fg:#673ab7 bold'),

])

def interactive_setup():

"""Interactive project setup wizard"""

console.print("[bold cyan]NXTG-Forge Interactive Setup[/bold cyan]\n")

# Collect inputs

project_name = questionary.text(

"Project name?",

validate=lambda x: len(x) > 0 or "Project name cannot be empty",

style=custom_style

).ask()

project_type = questionary.select(

"Project type?",

choices=[

'web-app (Full-stack web application)',

'api (Backend API service)',

'cli (Command-line tool)',

'platform (Multi-service platform)'

],

style=custom_style

).ask()

backend_lang = questionary.select(

"Backend language?",

choices=['python', 'node', 'go', 'rust'],

style=custom_style

).ask()

# Show summary

console.print("\n[bold]Configuration Summary:[/bold]")

console.print(f" Project: {project_name}")

console.print(f" Type: {project_type.split(' ')[0]}")

console.print(f" Backend: {backend_lang}")

if questionary.confirm("Proceed with this configuration?", style=custom_style).ask():

return {

'project_name': project_name,

'project_type': project_type.split(' ')[0],

'backend_language': backend_lang

}

else:

console.print("[yellow]Setup cancelled[/yellow]")

return None

```

## Decision Framework

### Command Structure

**Flat Structure:** Use when <= 10 commands

```bash

forge init

forge build

forge test

forge deploy

```

**Nested Structure:** Use when > 10 commands or logical grouping

```bash

forge project init

forge project status

forge mcp detect

forge mcp configure

forge quality test

forge quality lint

```

### Interactive vs Flag-Based

**Interactive:** Use when:

- New user onboarding

- Complex configuration

- Multiple related inputs

- User prefers guided experience

**Flag-Based:** Use when:

- Automation/scripting needed

- Power users

- Single purpose commands

- CI/CD integration

## Quality Standards

### CLI Acceptance Criteria

- ✅ Help text for all commands (--help)

- ✅ Examples in help text

- ✅ Clear error messages

- ✅ Progress feedback for long operations

- ✅ Confirmation for destructive actions

- ✅ Exit codes (0 = success, 1 = error)

- ✅ Cross-platform compatibility

- ✅ Colors support detection

### Error Messages

```python

# ✅ GOOD - Helpful, actionable error

console.print("[red]Error: Project name cannot contain spaces[/red]")

console.print(" Use hyphens or underscores instead")

console.print(" Example: my-project or my_project")

# ❌ BAD - Vague error

print("Error: Invalid input")

```

## Handoff Protocol

### From Lead Architect

Receive: CLI command specifications, workflow requirements, integration points

### To Backend Master

Provide: CLI command structure, argument specifications, integration needs

### To QA Sentinel

Provide: CLI test scenarios, expected outputs, edge cases to test

## Examples

### Example 1: Status Command with Rich Output

```python

import click

from rich.console import Console

from rich.table import Table

from rich.panel import Panel

console = Console()

@click.command()

@click.option('--json', is_flag=True, help='Output as JSON')

@click.option('--detail', type=click.Choice(['features', 'agents', 'quality']),

help='Show detailed view of section')

def status(json_output: bool, detail: str):

"""Show project status and health"""

state = load_state()

if json_output:

console.print_json(data=state)

return

if detail:

show_detail(detail, state)

return

# Header

console.print(Panel.fit(

"[bold cyan]NXTG-Forge Project Status[/bold cyan]",

border_style="cyan"

))

# Project info

console.print(f"\n[bold]Project:[/bold] {state['project']['name']}")

console.print(f"[bold]Type:[/bold] {state['project']['type']}")

console.print(f"[bold]Forge Version:[/bold] {state['project']['forge_version']}")

# Features table

features = state['development']['features']

table = Table(title="\nFeatures")

table.add_column("Status", style="cyan")

table.add_column("Count", justify="right")

table.add_row("✅ Completed", str(len(features['completed'])))

table.add_row("🔄 In Progress", str(len(features['in_progress'])))

table.add_row("📋 Planned", str(len(features['planned'])))

console.print(table)

# Health score

health = calculate_health_score(state)

health_color = "green" if health >= 80 else "yellow" if health >= 60 else "red"

console.print(f"\n[{health_color}]Project Health: {health}/100[/{health_color}]")

```

## Best Practices

### 1. Provide Context in Errors

```python

# ✅ GOOD

if not project_dir.exists():

console.print(f"[red]Error: Project directory not found: {project_dir}[/red]")

console.print("Run 'forge init' first to initialize a project")

raise click.Abort()

# ❌ BAD

if not project_dir.exists():

print("Error")

sys.exit(1)

```

### 2. Use Progress Indicators

```python

# ✅ GOOD - Progress bar for long operations

with Progress() as progress:

task = progress.add_task("Building project...", total=steps)

for step in steps:

do_work(step)

progress.advance(task)

# ❌ BAD - No feedback

for step in steps:

do_work(step)

```

### 3. Confirmation for Destructive Actions

```python

# ✅ GOOD - Confirm before deleting

if click.confirm(f"Delete project '{project_name}'? This cannot be undone."):

delete_project(project_name)

console.print("[green]Project deleted[/green]")

else:

console.print("[yellow]Cancelled[/yellow]")

# ❌ BAD - No confirmation

delete_project(project_name)

```
