Hostkeeper MVP Implementation Plan
⚠️ IMPORTANT HANDOFF INSTRUCTIONS: Before starting implementation, check PROJECT_STATE.md for current progress and what's already been completed. This ensures you're not repeating work or missing dependencies.
For Claude: REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
Goal: Build a cross-platform SSH/SFTP management tool with secure credential storage, host management, and cross-device sync capabilities through export/import functionality.
Architecture: Monolithic CLI application with embedded TUI using layered architecture (Command Layer → Core Engine → Storage Layer). Progressive enhancement approach starting with native SSH connections and basic TUI for management tasks.
Tech Stack: Go 1.21+, Cobra (CLI framework), Bubble Tea (TUI), golang.org/x/crypto/ssh, Viper (config management), JSON/YAML storage
Current Status: Planning Complete → Ready for Implementation (Check PROJECT_STATE.md for latest updates)
Task 1: Project Setup and Dependencies

Task 2: Core Data Models and Storage Layer
Files:
- Create:
internal/models/host.go - Create:
internal/models/key.go - Create:
internal/models/snippet.go - Create:
internal/models/config.go - Create:
pkg/storage/storage.go - Create:
pkg/storage/json_storage.go - Create:
test/storage_test.go
Step 1: Write Host model tests
// test/storage_test.go
package storage_test
import (
"testing"
"time"
"github.com/yourusername/hostkeeper/internal/models"
)
func TestHostModel(t *testing.T) {
now := time.Now()
host := &models.Host{
ID: "test-host-1",
Name: "Test Server",
Hostname: "192.168.1.100",
Port: 22,
Username: "admin",
Auth: models.AuthConfig{
Type: "key",
KeyID: "default-key",
},
Tags: []string{"test", "development"},
CreatedAt: now,
}
if host.ID != "test-host-1" {
t.Errorf("Expected ID 'test-host-1', got '%s'", host.ID)
}
if host.Name != "Test Server" {
t.Errorf("Expected name 'Test Server', got '%s'", host.Name)
}
if host.Port != 22 {
t.Errorf("Expected port 22, got %d", host.Port)
}
if len(host.Tags) != 2 {
t.Errorf("Expected 2 tags, got %d", len(host.Tags))
}
}
Step 2: Run test to verify it fails
go test ./test -v
Expected: FAIL with "undefined: models"
Step 3: Create Host model
// internal/models/host.go
package models
import "time"
// Host represents a SSH connection configuration
type Host struct {
ID string `json:"id"`
Name string `json:"name"`
Hostname string `json:"hostname"`
Port int `json:"port"`
Username string `json:"username"`
Auth AuthConfig `json:"auth"`
Tags []string `json:"tags,omitempty"`
CreatedAt time.Time `json:"created_at"`
UpdatedAt time.Time `json:"updated_at,omitempty"`
}
// AuthConfig represents authentication configuration
type AuthConfig struct {
Type string `json:"type"` // "password", "key", "both"
KeyID string `json:"key_id,omitempty"`
Password string `json:"password,omitempty"`
}
Step 4: Create Key model
// internal/models/key.go
package models
import "time"
// KeyPair represents SSH key pair
type KeyPair struct {
ID string `json:"id"`
Name string `json:"name"`
PrivateKey string `json:"private_key"`
PublicKey string `json:"public_key"`
Comment string `json:"comment,omitempty"`
KeyType string `json:"key_type"` // "rsa", "ed25519", etc.
CreatedAt time.Time `json:"created_at"`
}
// KeyInfo represents key metadata without sensitive data
type KeyInfo struct {
ID string `json:"id"`
Name string `json:"name"`
PublicKey string `json:"public_key"`
Comment string `json:"comment,omitempty"`
KeyType string `json:"key_type"`
CreatedAt time.Time `json:"created_at"`
}
Step 5: Create Snippet model
// internal/models/snippet.go
package models
import "time"
// Snippet represents a command snippet
type Snippet struct {
ID string `json:"id"`
Name string `json:"name"`
Description string `json:"description,omitempty"`
Command string `json:"command"`
Variables map[string]string `json:"variables,omitempty"`
HostID string `json:"host_id,omitempty"`
CreatedAt time.Time `json:"created_at"`
}
Step 6: Create Config model
// internal/models/config.go
package models
// AppConfig represents application configuration
type AppConfig struct {
Version string `json:"version"`
DefaultPort int `json:"default_port"`
ConnectionTimeout int `json:"connection_timeout"`
SFTPTimeout int `json:"sftp_timeout"`
LogLevel string `json:"log_level"`
Storage StorageConfig `json:"storage"`
Terminal TerminalConfig `json:"terminal"`
}
// StorageConfig represents storage configuration
type StorageConfig struct {
Encrypt bool `json:"encrypt"`
Compression bool `json:"compression"`
}
// TerminalConfig represents terminal configuration
type TerminalConfig struct {
ColorScheme string `json:"color_scheme"`
FontSize string `json:"font_size"`
}
// DefaultConfig returns default application configuration
func DefaultConfig() *AppConfig {
return &AppConfig{
Version: "1.0",
DefaultPort: 22,
ConnectionTimeout: 30,
SFTPTimeout: 60,
LogLevel: "info",
Storage: StorageConfig{
Encrypt: false,
Compression: false,
},
Terminal: TerminalConfig{
ColorScheme: "default",
FontSize: "medium",
},
}
}
Step 7: Create Storage interface
// pkg/storage/storage.go
package storage
import (
"context"
"github.com/yourusername/hostkeeper/internal/models"
)
// Storage defines the interface for data persistence
type Storage interface {
// Host operations
SaveHost(ctx context.Context, host *models.Host) error
GetHost(ctx context.Context, id string) (*models.Host, error)
ListHosts(ctx context.Context) ([]*models.Host, error)
DeleteHost(ctx context.Context, id string) error
UpdateHost(ctx context.Context, host *models.Host) error

GetSnippet(ctx context.Context, id string) (*models.Snippet, error)
ListSnippets(ctx context.Context) ([]*models.Snippet, error)
DeleteSnippet(ctx context.Context, id string) error

ImportData(ctx context.Context, data []byte, mergeStrategy string) error
}
Step 8: Create JSON Storage implementation
// pkg/storage/json_storage.go
package storage
import (
"context"
"encoding/json"
"fmt"
"os"
"path/filepath"
"github.com/google/uuid"
"github.com/yourusername/hostkeeper/internal/models"

Phase 2: TUI Overhaul & Enhanced Features
Task 15: TUI Tab Framework & Orange Theme
Files:
- Create:
pkg/tui/tabs.go— TabManager, tab bar renderer - Create:
pkg/tui/styles.go— All lipgloss styles (orange palette) - Modify:
pkg/tui/tui.go— Integrate TabManager, replace single-screen with tab routing
Step 1: Create styles.go
// pkg/tui/styles.go
package tui
import "github.com/charmbracelet/lipgloss"
// Orange theme palette
var (
OrangePrimary = lipgloss.Color("#FF6B00")
OrangeSecondary = lipgloss.Color("#FF9F43")
OrangeLight = lipgloss.Color("#FFB800")
DarkBg = lipgloss.Color("#1A1A1A")
LightBg = lipgloss.Color("#2D2D2D")
TextPrimary = lipgloss.Color("#FFFFFF")
TextSecondary = lipgloss.Color("#AAAAAA")
)
// Component styles
var (
TabActiveStyle = lipgloss.NewStyle().Background(OrangePrimary).Foreground(DarkBg).Bold(true).Padding(0, 2)
TabInactiveStyle = lipgloss.NewStyle().Background(LightBg).Foreground(TextSecondary).Padding(0, 2)
TabBarStyle = lipgloss.NewStyle().Background(DarkBg)
StatusBarStyle = lipgloss.NewStyle().Background(OrangePrimary).Foreground(DarkBg).Padding(0, 1)
TitleStyle = lipgloss.NewStyle().Foreground(OrangeSecondary).Bold(true)
HighlightStyle = lipgloss.NewStyle().Foreground(OrangePrimary).Bold(true)
SelectedStyle = lipgloss.NewStyle().Foreground(DarkBg).Background(OrangePrimary).Padding(0, 1)
)
Step 2: Create tabs.go — TabManager
Core structure:
Tabinterface withInit(),Update(msg),View(),Name() stringTabManagerholds slice of tabs + active index- Tab bar rendered via
TabActiveStyle/TabInactiveStyle - Keybind routing: tab-level keys (Ctrl+Tab, Ctrl+Q, Ctrl+N) vs tab-content keys
type Tab interface {
Init() tea.Cmd
Update(tea.Msg) (Tab, tea.Cmd)
View() string
Name() string
}
type TabManager struct {
tabs []Tab
active int
}
Step 3: Modify tui.go
Replace CurrentScreen Screen with *TabManager. Init creates default HostsTab. Update delegates to TabManager.Update(). View renders tab bar + active tab view + status bar.
Step 4: Verify
make build
./bin/hostkeeper tui
Expected: Tab bar visible at top with "Hosts" tab, orange theme, status bar at bottom. Keyboard navigation works (Ctrl+Tab cycles tabs if multiple exist).
Task 16: SSH Session Tab (Multi-Session)
Files:
- Create:
pkg/tui/session.go— SessionTab with live SSH terminal
Architecture:
┌─ Hosts ── Server Nico ── Web Prod ────────────────┐
│ │
│ $ htop │
│ $ cd /var/log │
│ $ tail -f syslog │
│ │
│ [live SSH session output] │
├─────────────────────────────────────────────────────┤
│ Connected to Server Nico — Ctrl+Q to disconnect │
└─────────────────────────────────────────────────────┘
SessionTab struct:
type SessionTab struct {
host *models.Host
client *ssh.Client // Go SSH client
pty *ssh.Session
width int
height int
input chan string // keyboard input → SSH stdin
output chan string // SSH stdout → TUI render
done chan struct{}
}
Key flows:
- User selects host in HostsTab → Enter → open SessionTab
- SessionTab connects via Go SSH client (auto-auth with stored password)
- Start PTY → 2 goroutines: stdin pump, stdout pump
- Keyboard input in TUI →
inputchannel → SSH stdin - SSH stdout →
outputchannel → TUI render (via tea.Batch) - Window resize →
msg tea.WindowSizeMsg→ SSH WindowChange - Ctrl+Q → close session → remove tab → back to HostsTab
- Multiple sessions = multiple tabs, each with its own goroutines
Verify:
make build
./bin/hostkeeper tui
# Select a host → Enter → SSH session tab opens
# Ctrl+Tab to switch between session and host list
# Ctrl+Q to close session
Task 17: TUI Host Forms (Add/Edit)
Files:
- Create:
pkg/tui/host_form.go
Form fields:
- Name (text input)
- Hostname/IP (text input)
- Port (number input, default 22)
- Username (text input)
- Auth Type (select: password/key/both)
- Password (text input, masked)
- Key (file selector or paste)
- Group (text input)
- Tags (text input, comma-separated)
- Notes (textarea)
Implementation:
- Use Bubble Tea
textinputmodel for each field - Tab/Shift+Tab to cycle fields
- Enter on last field → submit → save via storage
- Edit mode: pre-populate fields from existing host
- Cancel (Escape) → back to HostsTab without saving
Verify:
make build
./bin/hostkeeper tui
# HostsTab → press 'a' or Ctrl+N → form opens
# Fill fields → Enter → host saved → back to HostsTab
Task 18: TUI SFTP Browser
Files:
- Create:
pkg/tui/sftp_browser.go
Layout:
┌─ Hosts ── Server Nico ── SFTP ────────────────────┐
│ /var/www/ │
│ ──────────────────────────────────────────────── │
│ 📁 . <DIR> │
│ 📁 .. <DIR> │
│ 📁 html <DIR> 2026-01-15 │
│ 📄 index.html 4.2 KB 2026-01-15 │
│ 📄 config.php 1.1 KB 2026-01-14 │
│ 📁 assets <DIR> 2026-01-10 │
├─────────────────────────────────────────────────────┤
│ ↑↓:nav Enter:open u:upload d:download q:close │
└─────────────────────────────────────────────────────┘
Implementation:
- Reuse SSH connection from SessionTab (or create new one)
golang.org/x/crypto/ssh+github.com/pkg/sftpfor SFTP operations- File list sorted: dirs first, then files alphabetically
- Upload: local file picker (current directory) → remote path
- Download: selected file → local directory
- Navigation: Enter opens directory, Backspace goes up
Verify:
make build
./bin/hostkeeper tui
# SFTP tab → browse files → upload/download
Task 19: TUI Key & Snippet Management
Files:
- Create:
pkg/tui/key_list.go - Create:
pkg/tui/snippet_list.go
Key List Tab:
- List all saved SSH keys with name, type, fingerprint
- Select key → view details (public key, comment)
- Actions: generate new key, import from file, delete
- Generate: select type (RSA 4096, ED25519, ECDSA), optional passphrase
Snippet List Tab:
- List saved command snippets
- Select → preview command
- Execute snippet on connected host
- Create/edit snippets with name, command, description
- Variable substitution:
{{hostname}},{{user}},{{port}}
Verify:
make build
./bin/hostkeeper tui
# Keys tab → list/generate/import
# Snippets tab → list/create/execute
Phase 3: Advanced Features (Future)
Cloud Sync:
- User account system
- Encrypted cloud storage
- Real-time multi-device sync
- Conflict resolution
Advanced Terminal:
- Custom terminal emulator
- Advanced text selection
Integration:
- Web UI (optional)
- API access
- Plugin system
- Third-party integrations
