Composability Is the Secret Sauce

Skills Should Be LEGO Bricks

The best skills I've used share one trait: they compose beautifully. A great skill takes a well-defined input and produces a predictable output that another skill can consume.

The Composability Checklist

• Clear I/O contract: What goes in, what comes out
• Stateless by default: No hidden side effects
• Graceful with bad input: Validate and explain, don't crash
• Configurable depth: Simple defaults, powerful overrides

Skills that follow these rules can be chained into workflows the author never imagined. That's the magic.
