	tl;dr: fx is an experimental open-source (Apache-2.0) coding agent CLI written in Zig, weighing ~6MB with 10µs cold start and single-digit MB memory footprint. It's model-agnostic, works with local or cloud inference, and compiles to WebAssembly with pluggable networking. Unlike heavy terminal IDEs, it favors a Unix shell-like interface and is designed to be embeddable and extensible via skills, plugins, and MCPs.
	HN Discussion: ↑The feature list and minimalist design justify the project's existence and differentiation ↓Only the Zig implementation is novel; the harness and portability claims are oversold ↓The 6MB binary size is surprisingly large for what should be a simple Zig program ~Terminology is inconsistent - conflating 'agent' with 'agent harness' is confusing ↓Local inference claims are undermined by apparent Vercel account requirement
