loadout: Instructions file for GitHub Copilot

.github/instructions/makefile.instructions.md

loadout makefile.instructions.md is an instructions file for GitHub Copilot from stefaniuk/loadout. It costs 5,124 tokens per session, scanned C, original, MIT.

A set of instructions for using Makefiles as the standard command interface for local development and continuous integration. Makefiles are files that collect repeatable project commands.

In plain words
What is it for?
It is for structuring Makefile commands, shared command modules, variables, safety rules, security checks, and quality checks that match continuous integration.
Why use it?
It keeps developer and automated build commands consistent, while discouraging complicated programming inside the Makefile itself.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is stefaniuk/loadout's own configuration. It tells GitHub Copilot how to work on loadout itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything loadout configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

loadout makefile.instructions.md scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 22d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Makefile Engineering Instructions (developer experience, CI-aligned) 🛠️

These instructions define the default engineering approach for using Makefiles as orchestration, not as a place for complex logic.

They must remain applicable to:

  • Small repos with a single Makefile
  • Modular repos that include shared *.mk modules (recommended)
  • Repos where make is the canonical interface for local dev and CI/CD

They are non-negotiable unless an exception is explicitly documented (with rationale and expiry) in an ADR/decision record.

Identifier scheme. Every normative rule carries a unique tag in the form [MK-<prefix>-NNN], where the prefix maps to the containing section (for example OP for Operating Principles, LCL for Local-first developer experience, STR for Structure, UX for Target UX, SH for Shell & safety, VAR for Variables, SEC for Security, CI for CI alignment, QG for Quality Gates, and AI for AI-assisted expectations). Use these identifiers when referencing, planning, or validating requirements.


0. Quick reference (apply first) 🧠

This section exists so humans and AI assistants can reliably apply the most important rules even when context is tight.

  • [MK-QR-001] Thin root Makefile: keep the top-level Makefile small; push reusable logic into scripts/**/*.mk and scripts/**/*.sh ([MK-STR-001], [MK-STR-004], [MK-SH-008]).
  • [MK-QR-002] Help-first UX: default goal is help; every public target has an inline description and category ([MK-UX-001]–[MK-UX-006]).
  • [MK-QR-003] Safe by default: no destructive behaviour without explicit scoping and confirmation options ([MK-SEC-001]–[MK-SEC-006]).
  • [MK-QR-004] Fail fast: recipes must fail on errors; never hide failures ([MK-SH-001]–[MK-SH-006]).
  • [MK-QR-005] CI uses make: CI/CD should call the same targets developers run locally ([MK-CI-001]–[MK-CI-006]).
  • [MK-QR-006] Deterministic targets: stable outputs and consistent environment handling ([MK-OP-003], [MK-VAR-001]–[MK-VAR-006]).
  • [MK-QR-007] Small, testable changes: prefer incremental improvements; do not rewrite the build system as a "clean-up" ([MK-OP-002], [MK-AI-001]).
  • [MK-QR-008] Fast feedback: local development and tests must be quick and confidence-building ([MK-OP-005], [MK-LCL-001]–[MK-LCL-005]).
  • [MK-QR-009] Run the quality gates after any Makefile/script change and iterate to clean ([MK-QG-001]–[MK-QG-003]).
  • [MK-QR-010] Avoid common anti-patterns: || true without comment, large inline shell, hardcoded paths, unscoped rm -rf (§12).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
