Use Genkit for typed AI work and senro to organize that work into an executable pipeline. A registered senro function step can call a Genkit flow, pass its result to downstream steps, and expose execution facts through senro’s run event stream. The tools have complementary roles: Genkit handles flow and model integration; senro handles graph planning, execution, and run-level visibility.

What each layer does

Concern Genkit senro
Primary unit A typed flow that performs AI work, such as generating a summary. A function or command step within a workflow graph.
Responsibility Flow logic and integration with a model provider. Graph planning and execution, step state, and run-level visibility.
Visibility Genkit traces for flow activity. An append-only event stream of run facts that clients can attach to.
Retry and caching Keep model-specific logic in the flow where appropriate. Manage work at the step and pipeline level; configure behavior for the task rather than assuming every model request can safely be repeated or cached.

As the example author, Xavier Portilla Edo, puts it: “A Genkit flow is a great unit of AI work and a poor unit of orchestration.” That is an architectural framing, not a vendor guarantee. The integration keeps the flow as the AI unit while allowing senro to coordinate multiple units as a graph.

What the example uses—and what that establishes

The source article, dated September 11, 2026, reports an example using Genkit Go v1.13.1, senro v1.4.0, and googleai/gemini-2.5-flash. It says the sample ran against the real Gemini API; that result is the author’s report, not an independent execution or a guarantee of current compatibility. Check the release documentation for the versions you install, as well as current model access, regional availability, and pricing. The available sources do not establish those details for this exact combination.

For a fresh project, install Genkit Go and the senro module using the dependency versions appropriate to your application. The example’s version pins are historical to that report; verify current releases and package instructions before copying installation commands. Configure the provider and credentials in your application environment or secrets service, not as API keys embedded in source. Genkit’s Google Generative AI plugin guidance covers provider setup and explicitly warns against placing API keys directly in source.

Define a typed Genkit flow

Start with an ordinary Genkit flow with explicit input and output types. The source example uses a summarization flow that accepts document text and invokes Genkit generation inside the flow. Keeping the flow typed makes its contract clear to the caller and lets the same AI unit remain separate from pipeline orchestration.

// Illustrative shape: use the current Genkit Go API for your installed release.
type SummarizeInput struct {
    Text string
}

type SummarizeOutput struct {
    Summary string
}

// Define a Genkit flow that accepts SummarizeInput,
// calls the configured model, and returns SummarizeOutput.

This is a structural illustration, not a complete, version-verified program: flow registration and generation APIs can vary by release. Consult the Genkit repository and current Go documentation for the exact API and provider configuration. Genkit describes its project capabilities there; confirm the Go support and APIs against the version you choose.

Call the flow from a senro function step

Register a Go function with senro, then have that function read its step inputs or workspace, construct the typed flow input, invoke the flow, and return the output for downstream work. The boundary should remain visible: the step translates pipeline data into the flow’s input, calls Genkit, and propagates any error rather than disguising failure as a successful result.

// Illustrative control flow; adapt registration and workspace APIs
// to the senro release you install.
func summarizeStep(ctx context.Context, workspace Workspace) error {
    text, err := readDocumentInput(workspace)
    if err != nil {
        return err
    }

    result, err := summarizeFlow(ctx, SummarizeInput{Text: text})
    if err != nil {
        return err
    }

    return writeSummaryOutput(workspace, result.Summary)
}

The names above communicate the handoff, not guaranteed senro or Genkit symbols. Use senro’s release documentation for the actual function registration, input/workspace, and output APIs. The important integration pattern is that a normal Go function step invokes the flow; senro does not replace the flow’s model or prompt logic.

Build a graph for multi-document work

For a multi-document job, represent each independent summary as its own step and make a combine step depend on all of them. The graph expresses dependencies explicitly: independent summaries can be managed separately, and the combine step runs after its required outputs are available.

  1. Register one summary step per document. Each step reads its own document input, calls the typed Genkit flow, and stores one summary.
  2. Declare the combine step’s dependencies. It should consume the outputs of the summary steps rather than relying on hidden sequencing or shared mutable assumptions.
  3. Have the combine step produce the final result. It can join or otherwise process the individual summaries using the method your application requires.
  4. Resolve and execute the graph through senro. Inspect the run’s step state and event stream to understand which work completed or failed.

senro’s package documentation describes an immutable graph constructed in Go, a resolved execution plan, and an append-only stream of run facts. Its package documentation also lists command and registered function steps. This makes step boundaries useful for isolating work and examining failures; it does not imply that a model call is deterministic or that every failure should be retried.

Choose retries and caching for the workload

Retry transient failures selectively

A temporary provider or network failure may justify retrying a step. A deterministic error—such as invalid input or a prompt that consistently fails validation—usually calls for correcting the input or logic, not repeating the same work indefinitely. Set and validate policy for your own pipeline. The example describes retry behavior, but neither that description nor the execution model establishes a universally safe retry policy.

Cache only when the key and invalidation are sound

The article describes caching as a way for an unchanged document’s summary to be reused when another document changes. That is an illustrative account of the example, not a measured saving or a guarantee. Whether reuse is correct depends on what the output depends on: include relevant document content and any material prompt, model, configuration, or external-state changes in your cache design. Test cache keys and invalidation against your task. Model service behavior can be nondeterministic, so a prior output is not automatically interchangeable with a fresh generation.

Keep failure analysis optional

senro’s contrib/genkitanalyzer is a separate optional module for proposing explanations of failed steps. It does not make Genkit a required dependency for every senro user. The caller supplies an already configured Genkit instance and chooses the model, credentials, and telemetry setup. The analyzer’s output is a proposal: apply it only after human review or through an explicit policy, not as an assumed automatic repair.

See the genkitanalyzer package documentation for its construction and dependency boundary. Check the platform options and runtime constraints documented for the senro release you deploy; do not assume a support matrix from a different version applies unchanged.

Before deploying

  • Pin and verify the Genkit and senro versions you intend to use; the example’s reported versions are not a current-release claim.
  • Confirm the selected model identifier, API access, regional availability, and pricing in current provider documentation for your deployment.
  • Supply credentials through the application environment or a secrets service, not source code.
  • Test step input/output handoffs, error propagation, retry behavior, cache keys, and invalidation with representative workloads.
  • Use senro run events and step state to observe execution, while treating Genkit traces as complementary flow-level visibility.
