Gambit quickstart

Your assistant lives in a single file that enumerates each workflow step (we call it a deck).

Run it locally with the CLI, then implement the same .deck in your app when you're ready for production, or join the waitlist to be notified when Bolt Foundry’s hosted platform is available.

1. Install
$ npx @bolt-foundry/gambit serve
2. Open
Open http://localhost:8000 in your browser.

Keep your AI grounded, typed, and inspectable

Keep context small

Feed each tool only the facts it needs. Gambit scopes each workflow step to local context, so you don’t blow up token windows or hallucinate outside the source of truth.

Ditch mega-prompts

Break assistants into typed workflow steps, each with its own prompt or compute action. Swap models per step and reuse those steps anywhere.

Type-safe and easily debuggable

Define schemas once, enforce them at runtime, and ship with CLI and simulator traces baked in. Failures show up as structured logs instead of vague LLM output.
