Пре-мортем анализ рисков кода

testing

premortem is a Claude Code skill that identifies failure modes in plans, code, or designs before they cause real damage, applying Gary Klein's pre-mortem technique as framed by Shreyas Doshi. Risks are sorted into three categories: Tiger (a clear threat requiring action), Paper Tiger (looks dangerous but is actually fine), and Elephant (the concern no one wants to raise). Two analysis modes are available — quick for plans and PRs (2–3 minutes) and deep for pre-implementation reviews (5–10 minutes, covering scalability, security, integrations, data migrations, and test coverage gaps). A core safeguard prevents false positives: every potential Tiger must pass a verification checklist — reading ±20 lines of context, confirming no fallback or try/except branch exists, and checking whether the issue is even in scope — before it gets flagged. Teams doing structured risk analysis, pre-deploy quality assurance, or thorough PR reviews will find this skill practical for catching blind spots early.
