Hey Product Hunt! 👋 Built ZeroRules after watching Claude burn 850 tokens on "247 × 18" when my calculator could do it instantly for free. The problem: We're using LLMs for tasks that don't need AI - math, timezones, currency conversion, file listings. The solution: ZeroRules intercepts these queries BEFORE the API call using pattern matching, then resolves them locally in <5ms. Only creative/complex queries hit the LLM. ~70% token savings on typical workflows. Free forever for 5 core rules. $9/mo for custom rules. Also built SkillFence (just launched) - runtime monitor for the 341 malicious skills on ClawHub. Happy to answer questions!
