How does this skill handle stack documentation?

It uses standard stack effect notation (e.g., '( before -- after )') to document how each 'word' transforms the state of the stack.

What is point-free style?

Point-free or tacit programming is a style where function definitions do not identify the arguments (or 'points') on which they operate, instead relying on the composition of functions.

What is concatenative programming?

Concatenative programming is a paradigm where programs are formed by the concatenation of functions (words), which manipulate data on an implicit stack rather than using named variables.

Which languages does this skill support?

This skill provides specialized support for Forth, Factor, Joy, PostScript, and modern typed concatenative languages like Kitten or Cat.

Is this only for legacy languages like Forth?

No, it is highly relevant for modern DSL development, stack-based VM architecture, and functional programming patterns involving point-free composition.

Developer Tools

Enables stack-based concatenative programming patterns and composition-heavy code generation for languages like Forth, Factor, and Joy.

This skill equips Claude with specialized knowledge of concatenative programming paradigms, focusing on stack-based logic where composition replaces traditional function application. It provides deep expertise in point-free (tacit) programming styles, stack manipulation (DUP, SWAP, DROP), and categorical semantics. Whether you are developing DSLs for embedded systems, building stack-machine virtual machines, or optimizing functional pipelines, this skill ensures code is architected with extreme composability and rigorous stack effect documentation.
