Nexus CLI (Go) - Implementation Summary

Project Overview

Successfully implemented a production-quality, developer-focused TUI/CLI for rustlabs.ai using Go, Bubble Tea, and Lip Gloss. The application manages multiple OpenClaw agents in a single terminal interface.

✅ Completed Features

Core TUI Application

  • Three-panel layout: Agent Network (left), Chat viewport (right-top), Input bar (right-bottom)
  • Agent management: Spawn, kill, and restart agents with 4 presets (Full-Stack, DevOps, Data, SRE)
  • Real-time chat: Interactive messaging with mock streaming responses
  • Skills marketplace: Browse and install 6 mock dev skills
  • Command palette: Execute commands like /rename, /switch-model, /skills
  • Navigation: Full keyboard navigation with arrow keys, Tab, and shortcuts
  • Status indicators: Visual status (IDLE/RUNNING/ERROR) with color coding

Technical Implementation

  • Bubble Tea architecture: Clean separation of Model-Update-View
  • Lip Gloss styling: Beautiful, consistent terminal UI with adaptive colors
  • Mock backend: Fully functional with simulated responses for development
  • Configuration system: YAML-based config with rustlabs/custom modes
  • Modular structure: Clean separation of concerns across packages

CLI Commands

  • ./nexus - Launch TUI dashboard
  • ./nexus version - Show version info
  • ./nexus help - Display help and keybindings
  • ./nexus config - View configuration
  • ./nexus config edit - Edit configuration
  • ./nexus auth login - Authentication (stub)

Key Design Decisions

1. Bubble Tea Framework

  • Why: Industry-standard for terminal UIs in Go
  • Benefits: Clean architecture, testable, composable
  • Pattern: Elm Architecture (Model-Update-View)

2. Mock Backend

  • Why: Enable development and testing without real API
  • Benefits: Fast iteration, reliable testing, demo-ready
  • Implementation: Interface-based design for easy swap

3. Lip Gloss Styling

  • Why: Beautiful, adaptive terminal styling
  • Benefits: Consistent look, works across terminals
  • Features: Colors, borders, padding, layout

4. Modular Architecture

  • Why: Maintainability and extensibility
  • Benefits: Clear separation of concerns
  • Packages: ui, openclaw, skills, config

Technical Highlights

State Management

type Model struct {
    config        *config.Config
    client        openclaw.Client
    agents        []*openclaw.Agent
    selectedAgent int
    chatHistory   map[string][]openclaw.Message
    focus         FocusArea
    state         State
    // ... more fields
}

Event Handling

func (m Model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
    switch msg := msg.(type) {
    case tea.KeyMsg:
        return m.handleKeyPress(msg)
    case tea.WindowSizeMsg:
        m.updateLayout()
        return m, nil
    // ... more cases
    }
}

Async Operations

func (m Model) sendMessage(text string) (tea.Model, tea.Cmd) {
    return m, func() tea.Msg {
        ch, _ := m.client.SendMessage(ctx, agentID, text)
        for msg := range ch {
            return streamMsg{agentID, msg}
        }
        return streamDoneMsg{agentID}
    }
}

Build & Run
