Output infrastructure) + - Day 1-2: Implement gRPC client wrapper (Checkpoint 2) + - Day 3-4: Implement output utilities and patterns (Checkpoint 3) + - Day 5: Unit tests and validate with `TestUserCommand`, `TestNodeCommand` + +3. **Week 3**: Checkpoints 4-5 (Patterns and Validation infrastructure) + - Day 1-2: Implement command patterns infrastructure (Checkpoint 4) + - Day 3-4:

Tests (run after each checkpoint):** +```bash +# Run all CLI unit tests +go test ./cmd/headscale/cli/... -v + +# Run specific test files +go test ./cmd/headscale/cli/flags_test.go -v +go test

comparison +time go run ./cmd/hi run "TestUserCommand" +``` + +### Dependencies & Risks +- **Risk**: Breaking existing functionality during refactoring + - **Mitigation**: Comprehensive testing at each checkpoint +- **Risk**: Performance impact from additional abstractions + - **Mitigation**: Benchmark testing and optimization +- **Risk**: CLI currently has zero unit tests, making refactoring risky + - **Mitigation**: Create unit test infrastructure first (Checkpoint 0) +- **Dependency**: Understanding of all current CLI usage patterns + - **Mitigation**: Thorough analysis before implementation + +## Phase 2: Intelligent Flag System Redesign + +### Objective +Replace the current confusing and inconsistent flag system with intelligent, reusable identifier resolution that works consistently across all commands. + +### Current Flag Problems Analysis + +#### Inconsistent Identifier Flags +**Current problematic patterns:** +```bash +# Node identification - 4 different ways! +headscale nodes delete --identifier 5 # nodes use --identifier/-i +headscale nodes tag -i 5 -t tag:test # nodes use -i short form +headscale debug create-node --id 5 # debug uses --id + +# User identification - 3 different ways! +headscale users destroy --identifier 5 # users use --identifier +headscale users list --name username # users use --name +headscale preauthkeys --user 5 create # preauthkeys use --user + +# API keys use completely different pattern +headscale apikeys expire --prefix abc123 # API keys use --prefix +``` + +#### Problems with Current Approach +1. **Cognitive Load**: Users must remember different flags for similar operations +2. **Inconsistent Behavior**: Same flag name (`-i`) means different things in different contexts +3. **Poor UX**: Users often know hostname but not node ID, or username but not user ID +4. **Flag Definition Scattered**: Flags defined far from command logic (in `init()` functions) +5. **No Intelligent Lookup**: Users forced to know exact internal IDs + +### Phase 2 Implementation Plan + +#### Checkpoint 1: Design Intelligent Identifier System +**File**: `cmd/headscale/cli/identifiers.go` + +**New Unified Flag System:** +```bash +# Node operations - ONE consistent way +headscale nodes delete --node "node-hostname" # by hostname +headscale nodes delete --node "5" # by ID +headscale nodes delete --node "user1-laptop" # by given name +headscale nodes tag --node "192.168.1.100" -t test # by IP address + +# User operations - ONE consistent way +headscale users destroy --user "john@company.com" # by email +headscale users destroy --user "john" # by username +headscale users destroy --user "5" # by ID + +# API key operations - consistent with pattern +headscale apikeys expire --apikey "abc123" # by prefix +headscale apikeys expire --apikey "5" # by ID +``` + +**Intelligent Identifier Resolution Functions:** +```go +// Core identifier resolution system +type NodeIdentifier struct { + Value string + Type

ValidateUniqueNodeMatch(matches []*v1.Node, identifier string) (*v1.Node, error) +func ValidateUniqueUserMatch(matches []*v1.User, identifier string) (*v1.User, error) +``` + +#### Checkpoint 2: Create Smart Flag Registration System +**File**: `cmd/headscale/cli/smart_flags.go` + +**Goal**: Move flag definitions close to command logic, make them reusable + +**Before (current scattered approach):** +```go +// In init() function far from command logic +func init() { + listNodesCmd.Flags().StringP("user", "u", "", "Filter by user") + deleteNodeCmd.Flags().Uint64P("identifier", "i", 0, "Node identifier (ID)") + err := deleteNodeCmd.MarkFlagRequired("identifier") + // ... repeated everywhere +} +``` + +**After (smart flag system with backward compatibility):** +```go +// Flags defined WITH the command, reusable helpers + backward compatibility +var deleteNodeCmd = &cobra.Command{ + Use: "delete", + Short: "Delete a node", + PreRunE: SmartFlags( + RequiredNode("node"), //

node.GetName())) { + return + } + + client := MustGetClient(cmd) + client.DeleteNode(&v1.DeleteNodeRequest{NodeId: node.GetId()}) + }, +} +``` + +**Smart Flag System Functions:** +```go +// Smart flag

`cmd/headscale/cli/node_resolution.go` + +**Smart Node Resolution Logic:** +```go +func ResolveNode(client *ClientWrapper, identifier string) (*v1.Node, error) { + allNodes, err :=

findNodesByIPAddress(nodes []*v1.Node, identifier string) []*v1.Node +``` + +#### Checkpoint 4: Implement User Identifier Resolution +**File**: `cmd/headscale/cli/user_resolution.go` + +**Smart User Resolution Logic:** +```go +func ResolveUser(client *ClientWrapper, identifier string) (*v1.User, error) { + allUsers, err := client.ListUsers(&v1.ListUsersRequest{}) + if err != nil { + return nil,

identifier '%s', matches: %s", + identifier, formatUserMatches(unique)) + } + + return unique[0], nil +} +``` + +#### Checkpoint 5: Implement List Command Filtering +**File**: `cmd/headscale/cli/list_filtering.go` + +**Smart Filtering for List Commands:** +```bash +# New filtering capabilities +headscale nodes list --user "john" # Show nodes for user john +headscale nodes list --node "laptop" # Show nodes matching "laptop" +headscale users list --user "@company.com" # Show users from company.com domain +headscale nodes list --ip "192.168.1." # Show nodes in IP range

Examples:** + +**Before (nodes delete):** +```go +var deleteNodeCmd = &cobra.Command{ + Use: "delete", + Run: func(cmd *cobra.Command, args []string) { + output, _ := cmd.Flags().GetString("output") +

Comparison + +**Old Confusing Way:** +```bash +# User must know internal IDs and remember different flag names +headscale nodes list --user 5 # Must know user ID +headscale nodes delete --identifier 123 # Must know node ID +headscale users destroy --identifier 5 # Different flag for users +headscale apikeys expire --prefix abc123 # Completely different pattern +``` + +**New Intuitive Way:**

Command Documentation & Usage Streamlining + +### Objective +Transform the CLI from having inconsistent, unclear help text into a polished, professional tool with comprehensive documentation, clear examples, and intuitive command descriptions. + +### Current Documentation Problems Analysis + +#### Inconsistent Command Descriptions +**Current problematic help text:** +```bash +$ headscale nodes delete --help +Delete a node + +$ headscale users destroy --help +Destroys a user + +$ headscale apikeys expire --help +Expire an ApiKey + +$ headscale preauthkeys create --help +Creates a new preauthkey in the specified user +``` + +**Problems identified:** +1. **Inconsistent Tone**: "Delete" vs "Destroys" vs "Expire" vs "Creates" +2. **Unclear Consequences**: No explanation of what happens when you delete/destroy +3. **Missing Context**: No examples of how to use commands +4. **Poor Formatting**: Inconsistent capitalization and punctuation +5. **No Usage Patterns**: Users don't know the common workflows + +#### Missing Usage Examples +**Current state:** Most commands have no examples +```bash +$ headscale nodes list --help +List nodes +# No examples, no common usage patterns +``` + +**What users actually need:** +```bash +$ headscale nodes list --help +List and filter nodes in your Headscale network + +Examples: + # List all nodes + headscale nodes list + + # List nodes for a specific user + headscale nodes list --user "john@company.com" + + # List nodes matching a pattern + headscale nodes list --node "laptop" + + # List nodes with their tags + headscale nodes list

permanently + "show": "Show", // Display detailed information + "update": "Update", // Modify an existing resource + "expire": "Expire", // Mark as expired/invalid +} +``` + +**Standardized Command Description Patterns:** +```bash +# Consistent short descriptions (imperative verb + object) +"Create a new user" +"List nodes in your network" +"Delete a node permanently" +"Show detailed node
