Summary

  • Adds a features object to WorkflowMetadata (returned by getWorkflowMetadata()) with an encryption: boolean field indicating whether encryption is enabled for the current workflow run
  • Allows library authors to detect encryption at runtime and conditionally handle sensitive data serialization
  • Populated from the existing encryptionKey already threaded through both workflow VM and step contexts

Usage

import { getWorkflowMetadata } from "workflow"

async function processData(data: SensitiveData) {
    "use step"
    const { features } = getWorkflowMetadata()
    if (!features.encryption) {
        data = redact(data)
    }
    return data
}

Changes

  • packages/core/src/workflow/get-workflow-metadata.ts — Added features: { encryption: boolean } to WorkflowMetadata interface
  • packages/core/src/workflow.ts — Populate features in workflow VM context
  • packages/core/src/runtime/step-handler.ts — Populate features in step context
  • workbench/example/workflows/99_e2e.ts + packages/core/e2e/e2e.test.ts — E2E coverage
  • packages/core/src/serialization.test.ts, packages/core/src/step/writable-stream.test.ts — Updated test fixtures
  • docs/content/docs/api-reference/workflow/get-workflow-metadata.mdx — Documented the new field with example

Add features.encryption to WorkflowMetadata
89c6852 
Expose a `features` object on `getWorkflowMetadata()` so library
authors can detect at runtime whether encryption is enabled for the
current workflow run, allowing them to conditionally handle sensitive
data serialization.

Pull request overview

This PR exposes whether run-level encryption is enabled via a new features.encryption flag on WorkflowMetadata (returned by getWorkflowMetadata()), so libraries can adjust how they handle sensitive data.

Changes:

  • Extend WorkflowMetadata with features: { encryption: boolean }.
  • Populate features.encryption in both workflow VM context and step execution context.
  • Add/update E2E + unit tests and document the new field.

@TooTallNate
Improve docs example: show workflow-level encryption check
dc91e65 
Step inputs are serialized before the step body runs, so the encryption
check should happen in the workflow function before passing data to
steps.
@TooTallNate
Fix docs example: show encryption check on step return value
bed3fcd 
Step return values are serialized to the event log after the step body
runs, so this is where the check is actually useful - controlling what
data gets persisted as output.
