TypeSafe's official Claude Code skill: batching 13 questions in one call is 12.2x cheaper and 10x faster

TypeSafe released an official skill teaching Claude Code to build on Jev, praised as one of the best-written skills around. About 1,300 words, nearly every line stops the agent from guessing:
- Read TypeSafe's live docs before writing any code
- Keep rules, math and lookups in normal code; use Jev only for judgment calls
- Pick the right question type: Choice for one-of-a-set, Noul for yes/no, Score for degree
The biggest money-saver is asking independent questions together in one call: TypeSafe's own cookbook test showed 13 questions in one call came out 12.2x cheaper and 10x faster with the same answers.
Install via claude plugin marketplace add typesafe-ai/skills then claude plugin install typesafe@typesafe-ai. The skill is free and MIT licensed; using Jev requires a TypeSafe API key.
