 ## Logging Pattern
 Use `console.error` / `console.warn` / `console.info` / `console.debug` — no external logger. Color via `picocolors` in CLI output only.
 
+## CLI Command Pattern
+Each command is in its own file with a registration function:
+```ts
+// src/cli/agent.ts
+export function agentCommand(program: Command, config: Config, workspace: string): void {
+  program.command('agent')
+    .description('...')
+    .option('-m, --message <text>', 'Single message to process')
+    .action(async (opts) => { /* ... */ })
+}
+
+// src/cli/commands.ts (bootstrap)
+export function createCli(): Command {
+  const program = new Command('nanobot')...
+  const config = loadConfig(opts.config);
+  const workspace = resolveWorkspacePath(config.agent.workspacePath);
+  gatewayCommand(program, config, workspace);
+  agentCommand(program, config, workspace);
+  return program;
+}
+```
