ZeroRules — Deterministic Task Interceptor

What this skill does

ZeroRules eliminates wasted LLM tokens on tasks that don't need AI at all. Before you send a query to the model, check if ZeroRules can handle it instantly with zero tokens. Math, time zones, currency conversion, file listing, and date/scheduling queries all have deterministic answers that cost $0.

This is not model routing. Model routing sends simple queries to cheaper models. ZeroRules skips the model entirely.

When to use ZeroRules

ALWAYS attempt ZeroRules first when the user's message matches ANY of these patterns:

1. Math/calculations: Any arithmetic, percentages, unit conversions
2. Time queries: "What time is it in [city]?", "Current time in [timezone]"
3. Currency conversion: "$X to EUR", "convert [amount] [from] to [to]"
