zero-rules

What it does

ZeroRules intercepts queries that match deterministic patterns, math, time zones, currency conversion, file listing, and date calculations, and resolves them locally before any LLM call. It returns the result immediately with an estimate of tokens saved. Queries that don't match any rule pass through unchanged.

Why it's useful

Unlike model routing, which sends simple queries to a cheaper model, ZeroRules skips the model entirely and resolves answers locally at zero token cost.
