• ⚠️ Manual ANSI escape sequences in test files (acceptable for tests)

---

📊 Analysis by Component

1. Lipgloss Styling (✅ Excellent)

Current State:

• 29 Lipgloss usages in the console package
• All styling uses lipgloss.AdaptiveColor for light/dark theme support
• Centralized color palette in pkg/styles/theme.go with Dracula-inspired dark mode
• Consistent border usage: RoundedBorder for tables/boxes, NormalBorder for subtle emphasis

Strengths:

// ✅ EXCELLENT - Adaptive colors with light/dark variants
var ColorError = lipgloss.AdaptiveColor{
    Light: "#D73737", // Darker red for light backgrounds
    Dark:  "#FF5555", // Bright red (Dracula)
}

// ✅ EXCELLENT - Pre-configured semantic styles
var Error = lipgloss.NewStyle().
    Bold(true).
    Foreground(ColorError)

Available Pre-configured Styles:

• Status: Error, Warning, Success, Info
• Structure: FilePath, LineNumber, Command, Location
• Visual: Highlight, Header, Progress, Verbose
• Tables: TableHeader, TableCell, TableTotal, TableBorder
• Lists: ListHeader, ListItem
• MCP: ServerName, ServerType
• Trees: TreeEnumerator, TreeNode
• Boxes: ErrorBox

TTY Detection Pattern (✅ Proper):

func applyStyle(style lipgloss.Style, text string) string {
    if isTTY() {
        return style.Render(text)
    }
    return text
}

2. Huh Forms (✅ Excellent)

Current State:

• 131 Huh usages across CLI commands and campaign management
• Extensive use of interactive forms for user input
• Proper accessibility support via WithAccessible(console.IsAccessibleMode())

Form Types in Use:

• ✅ huh.NewInput() - Single-line text input (campaign IDs, tokens, names)
• ✅ huh.NewText() - Multi-line text input (objectives, instructions, workflows)
• ✅ huh.NewSelect[string]() - Single selection (triggers, engines, risk levels)
• ✅ huh.NewMultiSelect[string]() - Multiple selection (tools, safe outputs)
• ✅ huh.NewConfirm() - Yes/No prompts (overwrite, proceed, create project)

Example: Well-Structured Interactive Workflow Builder

// ✅ EXCELLENT - Organized into logical groups with proper styling
form := huh.NewForm(
    // Group 1: Basic Configuration
    huh.NewGroup(
        huh.NewSelect[string]().
            Title("When should this workflow run?").
            Description("Choose the GitHub event that triggers this workflow").
            Options(triggerOptions).
            Value(&b.Trigger),
    ),
    // Group 2: Capabilities
    huh.NewGroup(
        huh.NewMultiSelect[string]().
            Title("Which tools should the AI have access to?").
            Options(toolOptions).
            Value(&selectedTools),
    ),
).WithAccessible(console.IsAccessibleMode())

Accessibility Pattern (✅ Proper):

func IsAccessibleMode() bool {
    return os.Getenv("ACCESSIBLE") != "" ||
        os.Getenv("TERM") == "dumb" ||
        os.Getenv("NO_COLOR") != ""
}

// Applied to all forms
form := huh.NewForm(...).WithAccessible(console.IsAccessibleMode())

3. Console Formatting Package (✅ Excellent)

Architecture:

• Centralized formatting functions in pkg/console/
• Struct tag-based rendering with console:"header:Name,omitempty"
• Automatic table generation for slice data
• Progress bars and spinners with TTY detection

Key Components:

A. Table Rendering (✅ Modern Lipgloss Table)

// Uses lipgloss/table for modern table rendering
t := table.New().
    Border(border).
    BorderStyle(borderStyle).
    StyleFunc(styleFunc).
    Headers(headers...).
    Rows(rows...)

B. Progress Bars (✅ Gradient Support)

// Scaled gradient effect (purple → cyan)
progress.ShowPercentage = true
progress.Full = '█'
progress.Empty = '░'
progress.WithScaledGradient("#BD93F9", "#8BE9FD")

C. Spinners (✅ MiniDot Animation)

// Bubble Tea integration with accessibility
spinner := console.NewSpinner("Loading...")
spinner.Start()  // Respects ACCESSIBLE env var

D. Struct Rendering (✅ Reflection-based)

type Job struct {
    Name   string `console:"header:Name"`
    Status string `console:"header:Status,omitempty"`
}
fmt.Print(console.RenderStruct(jobs))  // Auto-generates table

4. Console Output Patterns

Current State Analysis:

✅ GOOD: Proper stderr usage with console formatting

// Most CLI commands follow this pattern
fmt.Fprintln(os.Stderr, console.FormatSuccessMessage("Compiled successfully"))
fmt.Fprintln(os.Stderr, console.FormatErrorMessage(err.Error()))

⚠️ ATTENTION: Direct stdout usage (17 instances)

Found direct fmt.Println and fmt.Printf to stdout in CLI commands:

File	Line	Pattern	Context
compile_orchestration.go	564	fmt.Println(jsonStr)	JSON output (acceptable)
deps_report.go	261	fmt.Println(string(jsonData))	JSON output (acceptable)
list_workflows_command.go	89, 180	fmt.Println(string(jsonBytes))	JSON output (acceptable)
file_tracker.go	86	fmt.Println("No files to stage")	❌ Should use stderr
pr_command.go	770	fmt.Printf("Creating PR: %s\n", title)	❌ Should use stderr + console formatting
run_workflow_validation.go	288, 315	fmt.Printf(...)	❌ Should use stderr + console formatting
tool_graph.go	232	fmt.Println(mermaidGraph)	✅ Graph output (acceptable)

Pattern Distinction:

• ✅ Acceptable: JSON output (--json flag), graph/diagram output (Mermaid)
• ❌ Needs improvement: User-facing messages without --json flag

---

🎯 Recommendations

Priority 1: Fix Stdout Anti-patterns (Low Priority)

Issue: 5 instances of user-facing messages using stdout without console formatting

Impact: Messages may not be styled consistently, could break when piping output

Fix Examples:

// ❌ BEFORE
fmt.Println("No files to stage")

// ✅ AFTER
fmt.Fprintln(os.Stderr, console.FormatInfoMessage("No files to stage"))

// ❌ BEFORE
fmt.Printf("Creating PR: %s\n", title)

// ✅ AFTER
fmt.Fprintln(os.Stderr, console.FormatProgressMessage(fmt.Sprintf("Creating PR: %s", title)))

Priority 2: Expand Lipgloss Layout Features (Future Enhancement)

Opportunity: The console package could leverage more Lipgloss layout features

Potential Additions:

1. Place utility for precise positioning
2. Join horizontal/vertical for complex layouts
3. Align for text alignment within boxes
4. Width/Height constraints for responsive layouts

Example Enhancement:

// Current: Manual string concatenation
// Enhanced: Lipgloss layout utilities
content := lipgloss.JoinVertical(lipgloss.Left,
    styles.Header.Render("Section 1"),
    styles.ListItem.Render("Item 1"),
    styles.ListItem.Render("Item 2"),
)

Priority 3: Consider Huh FilePicker (Future Enhancement)

Opportunity: Some file selection could use Huh's FilePicker

Current Pattern:

// Manual input for file paths
huh.NewInput().
    Title("Enter workflow file path").
    Value(&filePath)

Enhanced Pattern:

// Interactive file browser
huh.NewFilePicker().
    Title("Select workflow file").
    CurrentDirectory(".github/workflows").
    Value(&filePath)
```

### Priority 4: Document Console Formatting Patterns (Recommended)

**Opportunity**: Create a style guide for CLI developers

**Content:**
1. When to use each console format type (Error, Warning, Info, Success)
2. Stdout vs stderr guidelines (JSON to stdout, messages to stderr)
3. TTY detection patterns and when to disable styling
4. Accessibility requirements for interactive components
5. Table rendering best practices (borders, padding, headers)
