Score: 5.8/10 (Innovation: 6, Technical: 5, Documentation: 7, Utility: 5)

A collection of 7 guardrails (Claude Code hooks and pre-ship checks) built from recurring mistakes made by an AI agent over months. It turns hard-won operational lessons into mechanical blocks, with tests proving each guard works. The approach of growing rules from actual failures rather than speculation is a thoughtful pattern for agent safety.

Target audience: AI engineers, developers using Claude Code, and teams deploying autonomous coding agents
