What This Skill Does

Premortem is a zero-cost reasoning enhancement that makes every agent action better.

This is not a tool. This is not an API. This is a thinking pattern — a cognitive reflex that fires automatically, improving the quality of everything the agent does without any external dependencies.

When to Activate

Run a premortem pass before ANY of these actions:
