Premortem skill for engineering
A premortem asks: assume this change failed in production - why? The premortem skill has the agent list failure modes, rank them by likelihood and blast radius, and propose checks before you ship.
The Agent Skill Pack bundles production-grade agent skills such as premortem, code-review, a bug-class triad and a capacity oracle, installable into agent harnesses. A free OSS tier exists; Pro is $29/mo and Lifetime is $199 (pricing as of 2026-10-26).
