A claims-triage agent can interpret a request, find relevant evidence, and recommend what should happen next. It should not, by itself, decide where a claim goes, change an authoritative record, or authorize a payment. In a consequential workflow, a deterministic supervisor should control routing and retries, validate agent outputs against defined rules, and send unresolved cases to an authorized human.
What deterministic supervision means for claims
A supervisor is the workflow controller: it decides which step runs next, what conditions must be met, and whether the process can proceed. Making that controller deterministic means that routing, validation, retries, exception paths, and permission to commit changes follow explicit, testable rules—not an agent’s free-form judgment.
This does not mean every component must be deterministic. Agents can still interpret unstructured documents, summarize evidence, identify possible missing items, and draft explanations. The boundary is authority: an agent returns a proposal; a deterministic state validates it before any consequential action.
Ben Freiberg and Nithin Chandran Rajashankar put the principle plainly in the AWS Compute Blog article “Validating multi-agent decisions with Step Functions and Bedrock AgentCore,” published September 14, 2026: “The principle is that agents propose, and deterministic code validates.” For claims, that means a model-generated recommendation is an input to a decision process, not authorization to approve, deny, pay, or irreversibly alter a claim.

What AWS’s claims sample does—and does not—demonstrate
AWS’s insurance lifecycle sample describes assistance with creating claims, sending pending-document reminders, gathering evidence, and searching claims and customer knowledge repositories. Example prompts include “Create a new claim,” “Gather evidence for claim 5t16u-7v,” and “Which claims have open status?” They illustrate the types of interaction the sample is intended to support; they are not reported production outcomes.
The sample uses Amazon Bedrock Agents and Knowledge Bases, API action groups backed by Lambda business logic, S3-hosted OpenAPI schemas and data, synthetic claims data in DynamoDB, SNS notifications, and IAM permissions. Its scope is useful for understanding how an agent can assist with lifecycle tasks and retrieval. Synthetic example data and a sample implementation do not establish claims-adjudication accuracy, regulatory compliance, fraud reduction, faster settlement, or improved customer outcomes.
Keep the capabilities bounded. For instance, an evidence-gathering agent can return a summary with references to supporting records and flag a possible missing document. The workflow should check that the referenced records exist and that the proposed next step is allowed. A lookup or reminder with a predictable rule may not need an agent at all.
A proposed Step Functions pattern for claims triage
The following is a proposed design pattern applying AWS’s September 2026 Step Functions validation example to claims. It is not a verbatim AWS claims reference architecture. The Compute Blog example uses an airline scenario to show deterministic workflow states around agent tasks; the insurance lifecycle sample separately documents claims-related assistance.
Rank #3
- Receive and identify the case. Start the workflow from an intake event or an authorized request. Validate required identifiers and create or retrieve the claim through a conventional service or function, not a model-generated record write.
- Load authoritative context. Retrieve the applicable claim and policy records from systems of record. Keep source data distinct from agent summaries so that later validation can check which facts came from which record.
- Classify or extract material. Use an agent where interpreting unstructured material is valuable. Return structured candidate fields, a concise rationale, and references to the source material. Treat missing, malformed, or unsupported fields as validation failures rather than filling them by inference.
- Run bounded specialist work. Invoke only the specialists needed for the case—for example, evidence summarization or missing-document recommendations. Independent tasks can run in parallel, with explicit concurrency bounds and timeouts.
- Validate before transition. Deterministic states check required fields, provenance, consistency with authoritative records, and policy-defined requirements. A choice state can route a validated, permitted case onward; a failed check, conflict, timeout, or out-of-policy case should route to a defined exception path.
- Commit only an authorized action. A deterministic task performs an allowed update or downstream action only after the required validations pass. For actions requiring authority beyond the configured rules, wait for an authorized human decision and record that approval before proceeding.
- Record the outcome. Preserve the workflow result and relevant execution history according to the organization’s retention, privacy, and access-control requirements. Make clear which outputs were proposed by agents, which checks passed, and whether a human approved an exception.
Step Functions can provide the inspectable state machine around calls to Amazon Bedrock AgentCore. In the AWS Compute Blog pattern, AgentCore’s managed harness handles an individual model’s reasoning loop and tools, while Step Functions coordinates work across agents: fan-out, sequencing, validation gates, and exception routing. That separation gives the team an explicit place to test allowed transitions and inspect execution inputs and outputs. It does not, by itself, decide what records should be retained or who should be allowed to see them.
Choose orchestration to match the work
AWS’s Agentic AI Lens distinguishes among dynamic graphs for reasoning-driven workflows, Step Functions for deterministic workflow skeletons, and hybrid orchestration when a process needs both. The right choice depends on how much control a task needs and whether it genuinely benefits from agent reasoning.
| Approach | Best fit | Claims-triage use | Control consideration |
|---|---|---|---|
| Deterministic workflow | Known sequences, explicit conditions, and required gates | Required-field checks, policy-defined routing, retries, and authorized record updates | States and transitions are explicit and testable; define exception routes rather than allowing an agent to improvise them. |
| Dynamic agent graph | Reasoning-driven tasks whose next operation depends on what is discovered | Potentially useful for investigating unstructured evidence when a bounded set of steps is insufficient | Do not let flexibility become authority to take consequential actions. Put validation and action permissions outside the model’s free-form plan. |
| Hybrid orchestration | Workflows that need flexible interpretation inside a controlled process | A deterministic intake and commit path with bounded agent-assisted evidence analysis between them | Keep the agent’s scope narrow and make the handoff back to deterministic validation explicit. |
For predictable single-step work, use an ordinary service call or function instead of creating a sub-agent. AWS’s Agentic AI Lens recommends parallel execution for independent tasks, passing large results by reference through shared stores, and using timeouts and fallback paths for critical workflows. In a claims system, those techniques should protect downstream capacity and prevent a slow branch from silently blocking the whole case.

Bound fan-out, retries, and failure paths
Parallel specialist calls can reduce unnecessary sequencing, but unbounded fan-out can overload dependent services or make failures harder to control. The AWS Compute Blog’s Step Functions example describes a Distributed Map with MaxConcurrency to bound parallel work. In that article’s described context, omitting MaxConcurrency or setting it to zero allows a default maximum of up to 10,000 parallel child executions; the article also cites 40 concurrent iterations as the Inline Map threshold for considering Distributed mode. These are implementation figures from that article, not claims-performance measurements or universal capacity guarantees. Verify current Step Functions documentation, applicable mode and region, quotas, and account configuration before relying on them.
Best Value
- Set limits deliberately. Choose concurrency based on the capacity of the systems a branch calls, not only the state machine’s ability to launch work.
- Make retries safe. Define which transient failures merit a retry, cap retry behavior, and ensure a repeated request cannot create duplicate consequential actions. A timeout or exhausted retry should reach a visible failure or review state.
- Define fallbacks. Specify what happens when a specialist is unavailable, returns invalid output, or does not finish in time. Do not interpret silence or a partial result as approval.
- Handle conflicts explicitly. If an agent summary disagrees with an authoritative record, preserve the conflict for review instead of silently choosing one value.
Step Functions execution history can show state transitions and their inputs and outputs, supporting operational inspection. Teams still need retention, data minimization, access-control, and sensitive-data handling policies appropriate to claims information; an execution trace is not automatically a complete audit or a reason to retain every payload indefinitely.

Human review is part of the control design, not a generic fallback added after automation. Define which failures or case conditions require an adjuster or another authorized reviewer, what information the reviewer receives, and what decision or approval the workflow records before it resumes.
- Required evidence is missing or cannot be tied to a reliable source.
- Agent-extracted details conflict with policy or claim records.
- A case falls outside the rules configured for automatic processing.
- A specialist times out, returns an invalid structure, or fails a deterministic validation.
- A proposed action requires a level of authority not granted to the automated workflow.
The AWS Compute Blog uses a flight-cancellation example to illustrate why automated decisions can have immediate financial impact. Claims handling has its own financial and regulatory consequences, so the transferable lesson is to gate consequential actions—not to infer that the airline example establishes a claims policy or compliance standard.
Check the AWS service path before building
The current Amazon Bedrock User Guide says Bedrock Agents, now called Bedrock Agents Classic, is no longer open to new customers; existing customers can continue using it. The guide points readers toward Amazon Bedrock AgentCore for similar capabilities. New designs should evaluate the AgentCore path rather than assume Agents Classic is available for a new account, and teams should verify the service’s current availability and implementation details for their region and account before committing to an architecture.
This service-status distinction matters when interpreting the insurance lifecycle sample: it documents an Agents-based implementation, not a requirement to build new systems on Agents Classic. The orchestration principle—keep consequential control in deterministic workflow states—can be evaluated separately from the lifecycle of a particular agent service.
Quick Recap
Implementation checks before enabling consequential actions
- Define the authority boundary. List the exact actions an agent may propose and the actions only deterministic code or an authorized human may execute.
- Test validation and transitions. Exercise valid outputs, missing fields, unsupported claims, source conflicts, malformed responses, retries, and timeouts.
- Inspect traces and permissions. Verify that state inputs and outputs are useful for operations while access to sensitive claim data is appropriately restricted.
- Test the whole path. AWS’s insurance sample recommends checking intent interpretation, orchestration traces, API schemas and business logic, knowledge-base configuration and retrieval, and end-to-end response quality.
- Verify deployment assumptions. Confirm current service availability, quotas, region support, account configuration, and downstream capacity before rollout.
- Separate sample behavior from evidence of outcomes. A sample can help teams explore an implementation pattern, but it does not demonstrate production accuracy, legal compliance, or business improvement.
