Highlights
- Shared question definitions across a Promise client and an Effect service, for TypeSafe Jev (direct or via Cloudflare AI Gateway) and Laya.
- You send state and typed questions and get typed answers with probabilities; the library never invents a probability, threshold or model version.
- Question builders cover boolean, choice and ordinal types; literal keys are preserved, as the excerpt says just before it cuts off.
- pnpm add system-one is the Promise API with zero runtime dependencies; the Effect build needs effect and @effect/platform.
- Requires Node 22.18 or newer and is ESM only. MIT, 0 stars, created and pushed 2026-09-20.

README reviewed 2026-10-17; the captured excerpt cuts off mid-sentence right after the question-definition example, so returned types, error handling, gateway configuration and usage beyond install are unavailable in the digest.
Questions about this entry
Short answers drawn from the linked project or page.
A TypeScript library for typed decisions from System-1 models: TypeSafe Jev, directly or through Cloudflare AI Gateway, and Laya, offering both a Promise client and an Effect-native service.
You send a state and typed questions and receive typed answers with probabilities, so your own code applies thresholds and makes decisions; the README says the library never invents a probability, threshold, selected level or model version.
The example defines a boolean question for urgency, a choice question for department routing with literal option keys, and an ordinal question for customer frustration with levels from calm to very angry.
pnpm add system-one installs the Promise API with zero runtime dependencies; the Effect service additionally needs pnpm add effect @effect/platform, and the package requires Node 22.18 or newer and is ESM only.
The README says Jev can be reached directly or through Cloudflare AI Gateway, and the library treats both paths plus Laya as sources of the same typed questions and answers.

The excerpt ends mid-sentence right after the question-definition example, so output shapes, error types, gateway configuration, tests and any other usage examples are not documented in the digest.
