npx claudepluginhub yannabadie/meta-ygnRuns a structured pre-mortem on plans before execution, enforcing per-step risk checks, evidence sourcing, and action verdicts to catch failures early.
Validates implementation plans against codebase reality, architecture, quality, risks, and conventions before execution using four parallel specialized reviewers.
