Russian / Русский --- Why this exists You ship a product — feels well thought out. Three months later it's dead. And the whole way through, Claude was cheerfully nodding: \"yeah, solid plan, good luck!\" That's not a bug in any specific model. It's the default behaviour of all LLMs. Ask \"what could go wrong?\" and you get hedged, polite, generic risk lists. Ask \"is this a good plan?\" and the model finds reasons to say yes. Premortem breaks the pattern. Not \"evaluate this plan,\" but \"imagine the plan has already failed — explain how it died.\" The model switches into narrative mode and produces concrete, creative, honest causes instead of hedging. Mitchell, Russo & Pennington (1989) measured 30% more specific causes of future outcomes under past-tense framing than under conditional framing. Kahneman called premortem his single most valuable decision-making tool. This skill ports the method into Claude Code as a reproducible session with deterministic mechanics and persistent history. --- What it does The session has four phases: - Pre-flight — syncs context with what the project already knows (CLAUDE.md, attached briefs), only asks for what's missing. - Silent scan — three parallel helpers look at the plan from six angles (Customer, Operator, Adversary, Assumptions, situational angle, an","default_branch":null,"files":null,"tree":[],"storefront":"/r/AndyShaman","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/AndyShaman/premortem/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
