pre-mortem
what it does
Run a pre-mortem risk analysis on a PRD or launch plan. Categorizes risks as Tigers (real problems), Paper Tigers (overblown concerns), and Elephants (unspoken worries), then classifies as launch-blocking, fast-follow, or track. Use when preparing for launch, stress-testing a product plan, or identifying what could go wrong.

Download the .zip and unzip it. Put its files, in a folder named pre-mortem, here:
~/.claude/skills/Every project. For one project only, use .claude/skills/ inside it.~/.agents/skills/Every project. For one repository only, use .agents/skills/ inside it.~/.cursor/skills/Cursor also reads the Claude Code and Codex folders above.Then start a new session and ask for what the skill does. Other agents that read SKILL.md have their own skills folder; check their docs.
Coming after launch: get skills from inside your agent, no download needed.
