crux

Design and author agentic workflows using the crux DSL — both YAML pipeline files (.crux) and Rust macro-based agents. Use when writing a .crux pipeline, designing an agent workflow, choosing between crux combinators (pipe, join_all, speculate, route_on_confidence, delegate), or planning how to decompose a task into crux steps. Triggers on "write a pipeline", "crux pipeline", ".crux file", "agentic workflow", "agent plan", "step handler", "which combinator", or any request involving pipeline design, step composition, or handler selection. Also use when reviewing or debugging existing pipelines.

Working with the crux codebase — an agentic Rust DSL and runtime trace model. Use when navigating crux source code, building crux from source, adding crux as a dependency, understanding crate boundaries, or debugging crux compilation issues. Triggers on "crux crate", "crux workspace", "crux build", "add crux dependency", "crux types", "CruxCtx", "Crux<T>", or any work inside the crux repo or a repo that depends on crux crates. Also use when someone asks about crux naming — the project was renamed from cruxx-* to crux-* in May 2026.
