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

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,

`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

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 information" +"Update user settings" +"Expire an API key" + +# Consistent long descriptions (what + why + consequences) +"Create a new user in your Headscale network.
