​
Phase Component

The <Phase> component groups related steps semantically, providing structure and observability to workflows.

​
Basic Usage

import { Phase } from "smithers";

<Phase name="Research">
  <Claude allowedTools={["Read", "Glob", "Grep"]}>
    Research the codebase.
  </Claude>
</Phase>

​
Props

​
name
string
Name of the phase for logging and tracking.
<Phase name="Implementation">
  <Claude>Implement the feature.</Claude>
</Phase>

​
Multi-Phase Workflow

function FeatureWorkflow() {
  const [phase, setPhase] = createSignal("research");

  return (
    <Ralph maxIterations={10}>
      {phase() === "research" && (
        <Phase name="Research">
          <Step name="find-files">
            <Claude
              allowedTools={["Glob", "Grep"]}
              onFinished={() => setPhase("implement")}
            >
              Find relevant files.
            </Claude>
          </Step>
        </Phase>
      )}

      {phase() === "implement" && (
        <Phase name="Implementation">
          <Step name="write-code">
            <Claude
              allowedTools={["Edit", "Write"]}
              onFinished={() => setPhase("test")}
            >
              Implement the solution.
            </Claude>
          </Step>
        </Phase>
      )}

      {phase() === "test" && (
        <Phase name="Testing">
          <Claude
            allowedTools={["Bash"]}
            onFinished={(r) => {
              if (r.output.includes("PASS")) {
                setPhase("done");
              } else {
                setPhase("implement");
              }
            }}
          >
            Run the tests.
          </Claude>
        </Phase>
      )}
    </Ralph>
  );
}

​
Database Tracking

Phases are tracked in the database: 
// Phases are automatically tracked when using SmithersProvider
const phases = await db.phases.list(executionId);
// [
//   { id: "p1", name: "Research", status: "complete", ... },
//   { id: "p2", name: "Implementation", status: "running", ... },
// ]
