First public release of the premortem skill for Claude Code.

A structured premortem session — finds in 10–15 minutes the holes in a concrete plan, launch, hire, or decision that would otherwise show up only after the failure.

What's inside

  • Four-phase session: pre-flight context sync → silent multi-agent scan (3 parallel helpers, 6 angles) → live dialog with strategic options per hole → atomic persist with history snapshots
  • Built-in: outside view (Kahneman & Lovallo 2003), bias scan with 6 items from the Kahneman/Lovallo/Sibony HBR 2011 checklist, conditional reverse-premortem (Klein 2025)
  • Persistent history: re-run after a month, see which holes closed / got worse / are new
  • 104 tests covering the deterministic CLI mechanics
