description	Scaffold a new Lumen CLI command following the Commander.js register pattern. TRIGGER when user asks to create, add, or implement a new CLI command or subcommand.

Scaffold New Lumen CLI Command

Lumen is CLI-first. Every feature starts as a CLI command. Follow all rules in CLAUDE.md.

Before Scaffolding

1. Check src/cli.ts for already-registered commands
2. Check if a stub exists in src/commands/
3. Decide: does this command need LLM? If no, it must work fully offline

Steps

1. Create or edit src/commands/<name>.ts using templates/command.ts.md
2. Register in src/cli.ts:

   import { registerX } from './commands/x.js';
   registerX(program);
   

3. Run npx tsc --noEmit to verify
4. Test: LUMEN_DIR=$(mktemp -d) npx tsx src/cli.ts <command> <args>

Command-Specific Rules

• Every command needs .description() for --help
• Async actions must wrap in try/catch — Commander does not handle rejections
• Use audit() for operations that change state (add, compile, delete)
• Use loadConfig() for settings, getDb() for database — both auto-initialize
