Makefile Script Developer

Production-ready GNU Makefiles. Strict shell + validated env + logging + safety gates.

When to use

• The user asks to write, scaffold, or harden a Makefile.
• The user wants to add or refactor a make target / workflow / build pipeline.
• The user wants to automate Terraform / Helm / kubectl / Docker / build / release through make.
• The user wants a self-documenting help target or wants to clean one up.
• A task chain ends in "and put it in a Makefile so I can run make deploy ...".

Required structure

Every Makefile you write starts from this skeleton. Do not omit SHELL := /bin/bash, the .SHELLFLAGS line, or .DEFAULT_GOAL := help. Recipes are TAB-indented, not spaces.
