Nice — just checked it out. The interceptor approach makes sense for teams that need policy enforcement across multiple agents.

Interesting difference in philosophy though: Limits enforces rules defined upfront, while what I built learns rules from production receipts. After 1100+ task completions, the dispatch patterns look completely different from what I would have designed on day one.

Probably complementary — you'd want both. Pre-defined guardrails for the dangerous stuff (your approach), and pattern evolution for the quality/efficiency stuff (mine).
