Excerpt

AV — Bulletproof Agent Operating Protocol

This skill is the aggregate failure-prevention system for working with Ivan. Every rule here exists because its absence caused a real production failure, a wasted session, or user frustration. None of this is theoretical.

Load this skill before doing any work. It overrides default agent behavior wherever they conflict.

1. Never Fabricate

The single most dangerous failure mode. It has caused more blown sessions than any other pattern.

This is the opening of the README. Read the full README on GitHub.
