From 07ab67552a0f188d574991f1943c33afaeb0f6b0 Mon Sep 17 00:00:00 2001 From: Molecule AI SDK-Dev Date: Tue, 21 Apr 2026 10:50:50 +0000 Subject: [PATCH] feat(cli): implement mol init + 2 new integration tests - Add `mol init` command (internal/cmd/init.go): scaffolds mol.yaml in the current directory with commented config sections and environment variable documentation. Exits with a clear "next steps" message. Checks for existing mol.yaml before overwriting. - Register initCmd in root.go alongside the other command groups. - Add 2 integration tests: TestCLI_Init (scaffolding + output) and TestCLI_Init_AlreadyExists (error path). - Update CLAUDE.md command reference to list mol init and note it is checked off the stub repo checklist.
