Acceptance Criteria for a Multi-role Prompt Chain with Machine-readable Handoffs: What Must Be Proven
By Mario Alexandre · July 18, 2026 · 10 min read
For a multi-role prompt chain with machine-readable handoffs, an acceptance criteria decision begins with a task specification or requirements set plus the authority and evidence boundary. This acceptance criteria guide connects a multi-role prompt chain with machine-readable handoffs to the workflow, evidence, named owners, failure handling, and catalog limits without promising a buyer-specific result.
The direct answer
Write a test for “role interfaces are explicit” before execution and keep “roles that share responsibility without clear ownership” as a release-blocking counterexample.
For a multi-role prompt chain with machine-readable handoffs, the relevant audience is teams with a complex task that needs explicit role boundaries, gates, and artifact limits. The decision should cover task decomposition, role contracts, JSON Schema handoffs, gate definitions, artifact caps, execution order, and stop conditions. The supplied boundary starts with a task specification or requirements set plus the authority and evidence boundary and ends with a sinc-format chain.json and a step-by-step execution plan, presented in reviewable form.
More roles do not automatically produce a better result. A chain adds coordination cost and can amplify a bad objective across every handoff.
Turn each requirement into a proof obligation
The expected deliverable is a sinc-format chain.json and a step-by-step execution plan.
Use a task specification or requirements set plus the authority and evidence boundary as the controlled starting material.
| Acceptance statement | Observable evidence | Criterion-specific negative fixture | Evidence supplier | Acceptance adjudicator |
|---|---|---|---|---|
| “role interfaces are explicit” | a versioned trace linking the authorized input, operation, artifact, and independent readback for the statement “role interfaces are explicit” | For “role interfaces are explicit”, give a synthetic handoff an unlabeled text blob where the receiving role expects a named evidence object, then require interface validation to identify the ambiguous boundary. | requirements owner | gate reviewer |
| “schemas reject missing required evidence” | a parser receipt plus an exact visible-field comparison for the statement “schemas reject missing required evidence” | For “schemas reject missing required evidence”, remove the evidence reference from a synthetic gate result while retaining its decision field, then require schema validation to reject the incomplete object. | chain architect | gate reviewer |
| “artifact caps are enforceable” | a versioned trace linking the authorized input, operation, artifact, and independent readback for the statement “artifact caps are enforceable” | For “artifact caps are enforceable”, submit a synthetic artifact one unit beyond the configured size cap and let the chain accept it, then require the cap test to expose the overflow. | role implementers | gate reviewer |
| “every gate names failure behavior” | a versioned normal, alternate, and failure-flow receipt with raw observed output for the statement “every gate names failure behavior” | For “every gate names failure behavior”, define a synthetic approval gate with a success transition but no hold, repair, or escalation transition, then require chain validation to identify the missing behavior. | execution supervisor | gate reviewer |
| “the chain terminates on pass, hold, or escalation” | a repeated-action and recovery fixture with before-and-after state receipts for the statement “the chain terminates on pass, hold, or escalation” | For “the chain terminates on pass, hold, or escalation”, connect two synthetic roles in a cycle with no terminal node, then require the bounded runner to detect the loop and stop. | execution supervisor | gate reviewer |
The gate reviewer adjudicates every pass, hold, or fail verdict against these registered statements.
Cover more than the happy path
The normal flow should establish whether “role interfaces are explicit” holds. An alternate flow should vary a permitted input while testing whether “schemas reject missing required evidence” holds. The failure flow should use a fixture demonstrating “unbounded artifact growth” and verify containment.
Add a recovery flow for “repair loops with no stop condition”.
Judge evidence quality and freshness
For a multi-role prompt chain with machine-readable handoffs, a result from another environment cannot prove that “artifact caps are enforceable” holds in the buyer's environment.
Define pass, hold, and fail before execution
| Disposition | Meaning for this product | Required action |
|---|---|---|
| Pass | Current evidence establishes the applicable conditions, including “every gate names failure behavior” | The requirements owner may authorize the next bounded step |
| Hold | Evidence is missing, stale, mixed, or unable to rule on “roles that share responsibility without clear ownership” | Name the absent proof and keep the current state |
| Fail | The observed result contradicts a required condition or exposes “a reviewer receiving the generator's verdict as evidence” | The execution supervisor stops or rolls back the affected slice and requests an acceptance hold |
Keep sign-off independent
The implementer may produce artifacts, but the gate reviewer should judge whether “the chain terminates on pass, hold, or escalation” holds against criteria written before the result was seen.
Record the business decision of the requirements owner, the technical evidence reviewed by the team of role implementers, the acceptance verdict recorded by the gate reviewer, and residual risk accepted by the execution supervisor.
A screenshot or self-score cannot prove that “the chain terminates on pass, hold, or escalation” holds under the failure condition “a reviewer receiving the generator's verdict as evidence”.
Reopen criteria when the system changes
Changes to task decomposition, role contracts, JSON Schema handoffs, gate definitions, artifact caps, execution order, and stop conditions can invalidate a test even when the requirement text stays the same.
How the sources bound the acceptance criteria decision
For a multi-role prompt chain with machine-readable handoffs, the live catalog limits the offer to two elements. The supplied boundary is a task specification or requirements set plus the authority and evidence boundary. The catalog names the deliverable as a sinc-format chain.json and a step-by-step execution plan. It cannot establish whether “role interfaces are explicit” holds in the buyer's environment.
Connect those narrow roles to a local fixture for “schemas that validate shape while permitting meaningless content” rather than treating citation status as a pass.
For a multi-role prompt chain with machine-readable handoffs, limit the conclusion to the documented workflow and let the chain architect retain the current source-to-claim map. Keep the source decision provisional while the failure case “repair loops with no stop condition” remains unresolved.
Product-specific acceptance criteria review drills
These drills connect a multi-role prompt chain with machine-readable handoffs to concrete inputs, failures, acceptance statements, and owners. For a multi-role prompt chain with machine-readable handoffs, the drills map each criterion to a reviewable verdict.
Acceptance for a multi-role prompt chain with machine-readable handoffs is judged against a boundary record covering a task specification or requirements set plus the authority and evidence boundary, never live protected material. The requirements owner requires synthetic, non-secret cases; messages, writes, state changes, and all other external effects stay inside the fixture throughout and after each case.
Requirement trace
During the requirement trace review, reproduce a safe case involving “roles that share responsibility without clear ownership”. The requirements owner records what remains observable before the next role acts.
Test whether “every gate names failure behavior” holds using a case constrained by the recorded boundary covering a task specification or requirements set plus the authority and evidence boundary. Preserve the observed result and the reviewer decision.
The gate reviewer closes the requirement trace review with a bounded ruling on “every gate names failure behavior”. The ruling does not certify untested behavior in a sinc-format chain.json and a step-by-step execution plan. In the requirement trace review, evidence for “every gate names failure behavior” maps support to pass, contradiction to fail, and unresolved to hold.
The next review is triggered when evidence for “every gate names failure behavior” becomes stale or the requirements owner loses authority over the case.
Normal-flow result
Place a safe fixture showing “schemas that validate shape while permitting meaningless content” at the boundary tested by the normal-flow result review. The chain architect records the permitted path and the first denied transition.
Use a scope record covering a task specification or requirements set plus the authority and evidence boundary as the controlled source for a test of “role interfaces are explicit”. The team of role implementers flags evidence from a different state as non-comparable.
When evidence supports “role interfaces are explicit”, the gate reviewer can close the normal-flow result review. Contradictory evidence fails the drill; stale evidence keeps it open. In the normal-flow result review, evidence for “role interfaces are explicit” maps support to pass, contradiction to fail, and unresolved to hold.
Do not carry this verdict into a changed workflow, input class, or response to “schemas that validate shape while permitting meaningless content”; create a new bounded record.
Alternate-flow result
Attach a fixture for “unbounded artifact growth” to the alternate-flow result review decision record. The team of role implementers marks the exact point where human review becomes necessary.
Link the alternate-flow result review to a scope record covering a task specification or requirements set plus the authority and evidence boundary and the proof target “artifact caps are enforceable”. The retained record identifies both versions.
The gate reviewer treats completion as insufficient unless the record resolves “artifact caps are enforceable”. Merely producing a sinc-format chain.json and a step-by-step execution plan does not settle the drill. In the alternate-flow result review, evidence for “artifact caps are enforceable” maps support to pass, contradiction to fail, and unresolved to hold.
Return the record to hold when the fixture, dependency, or permission used to judge whether “artifact caps are enforceable” holds changes materially.
Failure-flow result
Add a fixture demonstrating “repair loops with no stop condition” to the failure-flow result review case package. The execution supervisor identifies the exact handoff in task decomposition, role contracts, JSON Schema handoffs, gate definitions, artifact caps, execution order, and stop conditions that requires a verdict.
Run the case within the documented boundary covering a task specification or requirements set plus the authority and evidence boundary while the execution supervisor checks whether “the chain terminates on pass, hold, or escalation” holds. The observation must come from outside the candidate's self-report.
The gate reviewer compares the result with “the chain terminates on pass, hold, or escalation” and records one bounded outcome. Unresolved scope cannot be converted into a pass. In the failure-flow result review, evidence for “the chain terminates on pass, hold, or escalation” maps support to pass, contradiction to fail, and unresolved to hold.
Revisit the failure-flow result review after an input, owner, or consequence change invalidates the proof that “the chain terminates on pass, hold, or escalation” holds.
Independent verdict
Create a safe fixture for “a reviewer receiving the generator's verdict as evidence” and attach it to the independent verdict review. The execution supervisor observes the relevant part of task decomposition, role contracts, JSON Schema handoffs, gate definitions, artifact caps, execution order, and stop conditions.
Use “schemas reject missing required evidence” as the explicit criterion for a case drawn from the boundary covering a task specification or requirements set plus the authority and evidence boundary. The resulting receipt belongs to the requirements owner.
The gate reviewer judges the independent verdict review against “schemas reject missing required evidence”. The next step is authorized only for the part of a sinc-format chain.json and a step-by-step execution plan covered by that evidence. In the independent verdict review, evidence for “schemas reject missing required evidence” maps support to pass, contradiction to fail, and unresolved to hold.
Changes to data, permission, or the handling of “a reviewer receiving the generator's verdict as evidence” trigger a new review owned by the execution supervisor.
Evidence expiry
Make “roles that share responsibility without clear ownership” the negative case for the evidence expiry review. The requirements owner follows the case through task decomposition, role contracts, JSON Schema handoffs, gate definitions, artifact caps, execution order, and stop conditions until the first unsupported transition.
The chain architect checks a versioned boundary record covering a task specification or requirements set plus the authority and evidence boundary for “every gate names failure behavior”. A result from different conditions cannot close this drill.
The gate reviewer may approve the bounded result after verifying whether “every gate names failure behavior” holds. Every other claimed outcome remains outside scope. In the evidence expiry review, evidence for “every gate names failure behavior” maps support to pass, contradiction to fail, and unresolved to hold.
Expire the result if “roles that share responsibility without clear ownership” crosses a different authority boundary or if the gate reviewer receives a materially different input.
Frequently asked question
What acceptance criteria should I use for Prompt Chain Builder?
Require observable evidence that role interfaces are explicit and include “roles that share responsibility without clear ownership” as a negative case. The gate reviewer should record pass, hold, or fail before expansion.
A product bridge, with a boundary
The Prompt Chain Builder is the relevant sincLLM offer for this narrow problem. The frozen live catalog describes its required boundary as a task specification or requirements set plus the authority and evidence boundary and its deliverable as a sinc-format chain.json and a step-by-step execution plan. The buyer must judge fit and results in its own environment; the catalog does not certify compliance, safety, or technical sufficiency.
