workflows/hello.tsx

Ghost doc — This is a real script found at workflows/hello.tsx in the Smithers repository. It demonstrates the simplest possible workflow with direct literal output (no AI agent).

​
Source

// workflows/hello.tsx
import { createSmithers, Workflow, Task } from "smithers-orchestrator";
import { z } from "zod";

const { smithers, outputs } = createSmithers({
  output: z.object({
    message: z.string(),
    length: z.number(),
  }),
});

export default smithers((ctx) => (
  <Workflow name="hello">
    <Task id="hello" output={outputs.output}>
      {{
        message: `Hello, ${ctx.input.name}!`,
        length: String(ctx.input.name).length,
      }}
    </Task>
  </Workflow>
));

​
Running

smithers run workflows/hello.tsx --input '{"name": "World"}'
Output: 
[hello] Starting run abc123
[hello] Done -> { message: "Hello, World!", length: 5 }
[hello] Completed

​
What This Demonstrates

  • Literal output — The Task receives a plain object instead of an agent prompt, producing deterministic output with no LLM call.
  • createSmithers — Registers a Zod schema and auto-generates the backing SQLite table. No manual DDL needed.
  • ctx.input — Access the input payload passed via --input on the CLI.
  • Resumable — If the workflow crashes after the task completes, re-running skips straight to the end because the output is already persisted.
