Premortem
Imagine the plan already failed, then explain why. This "prospective hindsight" tense-shift (Klein, HBR 2007) generates ~30% more failure causes than asking "what could go wrong?" — and the causes are more specific. The skill turns that mechanism into a repeatable run that ends in a revised plan, not just a list of worries.
Workflow Routing
| Trigger | Workflow |
|---|---|
| "premortem this", "run a premortem", "what could kill this", high-stakes plan | Workflows/RunPremortem.md (full: parallel deep-dive agents) |
| "quick premortem", small/personal decision, fast gut-check, thin context | Workflows/QuickPremortem.md (solo single-pass, no fan-out) |
| "update the premortem skill", add/fix a workflow | Workflows/Update.md |
Default to RunPremortem for anything with real stakes. Drop to QuickPremortem only when
the decision is small or the user explicitly wants speed.
