Makefile Validator
If you need to validate Makefiles before CI or catch subtle issues like missing .PHONY declarations, tab-versus-space errors, or credential leaks, this runs a layered check through GNU make syntax validation, mbake linting, and custom security audits. It returns explicit exit codes (0 for clean, 1 for warnings, 2 for errors) and only loads the relevant docs when it finds something. The deterministic flow means you run the validator script, interpret the findings, apply fixes, and rerun until clean. Fallback paths handle missing dependencies gracefully. It's built for deterministic, local-first validation rather than quick linting, so expect a thorough pass that catches both syntax problems and best-practice violations in one go.

Makefile Validator
Overview
Use this skill to validate Makefiles with a local-first, deterministic flow.
Default validator entrypoint:
bash scripts/validate_makefile.sh <makefile-path>
Validation layers:
- Dependency preflight (
python3,pip3,make) - GNU make syntax check (
make -n --dry-run) whenmakeis available mbake validatembake format --check- Custom security, best-practice, and optimization checks
- Optional
checkmakeandunmakechecks when installed
Trigger Guidance
Use this skill when the request includes Makefile quality, linting, validation, hardening, or troubleshooting.
Trigger Phrases
- "Validate this Makefile"
- "Lint my
.mkfile" - "Find issues in this build Makefile"
- "Check Makefile security problems"
- "Review this Makefile before CI"
Non-Trigger Examples
- Creating a brand new Makefile from scratch (use
makefile-generator) - Running build targets as part of delivery
- General shell scripting work unrelated to Makefiles
Deterministic Execution Model
Run from this skill directory for shortest commands:
cd devops-skills-plugin/skills/makefile-validator
