Lab Verdict

An excellent, zero-cost prompt library and Claude Code plugin for developers seeking to harden their AI agents against common logical and verification errors. It requires no signup and runs completely locally, though its effectiveness relies entirely on the underlying LLM's capacity to strictly follow markdown-based pre-flight checklists.
