Weft Ai Language

Weft is a Rust-based language that treats LLMs, humans, APIs, and infrastructure as first-class primitives you wire together like a typed graph. The compiler checks connections between nodes, Restate handles durable execution so your program survives crashes and multi-day human approval pauses, and you get a visual graph generated from code. It's built for AI workflows where you need to mix LLM calls, conditional gates, human-in-the-loop steps, and external APIs without writing a ton of orchestration boilerplate. This skill helps you write Weft programs, set up the dev environment (PostgreSQL, Restate, the works), and debug pipelines. If you're building agent systems that need to pause for approval or recover from failures gracefully, the durable execution model is worth the setup cost.

Weft AI Language

Skill by ara.so — Daily 2026 Skills collection.

Weft is a programming language (implemented in Rust) for AI systems where LLMs, humans, APIs, databases, and agents are base language primitives. You wire nodes together, the compiler type-checks every connection, and the program runs with durable execution backed by Restate (survives crashes, supports multi-day human-in-the-loop pauses). A visual graph view is generated automatically from code.

Installation & Setup
