Posts connected to the expressions topic.
A tour of what shipped this month — forward-chaining inference, explainable traces, what-if simulation, derived facts, the expression language, and collection conditions — with a link to the full story on each.
Stop passing in values you could compute. Derived facts are context values resolved on demand from other values — defaults, shared definitions, expressions, even lazy AI classifications — evaluated only when a rule actually reads them.
A small, deterministic expression language for computed values and conditions: read context with ctx.key, 32 built-in functions across strings, math, dates and arrays, null-safe with coalesce, and validated as you type.
