A generator for Makefiles, which are files that define repeatable project commands such as installing dependencies, checking code, running tests, and building packages.

It helps create or update Makefiles with targets for formatting, linting, type checking, testing, building, cleaning, and publishing.

It saves time when adding standard development commands or making them consistent across Python, Rust, and TypeScript projects.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00013	$0.00657
Opus 5	$0.00006	$0.00329
Sonnet 5	$0.00003	$0.00131
Haiku 4.5	$0.00001	$0.00066

Security

Grade A, and why

skill-063 scanned grade A with 0 findings 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 6d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Makefile Generation Skill

Generate a Makefile with standard development targets for Python, Rust, or TypeScript projects.

Use When

Need a Makefile for a project without one
Want to update Makefile with new targets
Standardizing build automation across projects

Standard Targets

Python Makefile

Common targets:

help - Show available targets
install - Install dependencies with uv
lint - Run ruff linting
format - Format code with ruff
typecheck - Run mypy type checking
test - Run pytest
test-coverage - Run tests with coverage report
check-all - Run all quality checks
clean - Remove generated files and caches
build - Build distribution packages
publish - Publish to PyPI

Rust Makefile

Common targets:

help - Show available targets
fmt - Format with rustfmt
lint - Run clippy
check - Cargo check
test - Run tests
build - Build release binary
clean - Clean build artifacts

TypeScript Makefile

Common targets:

help - Show available targets
install - Install npm dependencies
lint - Run ESLint
format - Format with Prettier
typecheck - Run tsc type checking
test - Run Jest tests
build - Build for production
dev - Start development server

Workflow

1. Detect Language

# Check for language indicators
if [ -f "pyproject.toml" ]; then
    LANGUAGE="python"
elif [ -f "Cargo.toml" ]; then
    LANGUAGE="rust"
elif [ -f "package.json" ]; then
    LANGUAGE="typescript"
fi

2. Load Template

from pathlib import Path

template_path = Path("plugins/attune/templates") / language / "Makefile.template"

3. Collect Project Info

metadata = {
    "PROJECT_NAME": "my-project",
    "PROJECT_MODULE": "my_project",
    "PYTHON_VERSION": "3.10",
}

4. Render Template

from template_engine import TemplateEngine

engine = TemplateEngine(metadata)
engine.render_file(template_path, Path("Makefile"))

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.

skill-063 is a skill published in the GitHub repository legendtkl/agentic-skill-router (5 stars, last pushed 3mo ago), licensed MIT. It adds 13 tokens to every session and 657 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
