Building Interactive Widgets in SitecoreAI from Structured Agent Outputs

An agent output becomes an interface when someone must inspect it, compare alternatives, or choose a next action. A long text response can contain useful findings while making those decisions difficult. A widget can organize the same findings into stable fields, evidence links, and explicit states. The engineering work begins with the data contract and the decision, not with a decorative score or a button whose effect nobody has defined.

Sitecore describes widgets as reusable components combining an expected data structure with a presentation template and a prompt. This article proposes a design for a hypothetical content-review widget fed by structured agent outputs. The JSON examples are application contracts, not native widget-definition schemas. No arbitrary JavaScript execution model, action callback API, or universal rendering framework is assumed. Verify the actual supported surfaces and permissions in your environment before implementing the design.

My position is that the first useful widget should expose evidence and uncertainty before it offers a consequential action. That may produce a quieter interface than an immediate Apply All button. I prefer that tradeoff for content workflows because a recommendation is easier to judge when the user can see what was assessed, what is missing, and which revision the result describes. The following design connects that interface to validation, authorization, testing, and release.

1. Start with a decision and a data contract

Choose the decision the widget should improve

Define the user’s job in one sentence. For the hypothetical review widget, a content owner needs to inspect agent findings about a draft and decide what deserves correction or further review. The widget should therefore identify the assessed artifact, the evidence behind each finding, and the proposed next step. It should not imply that the draft has been published or formally approved. A different decision, such as comparing campaign performance, would need a different contract and a different treatment of missing observations.

Start with the smallest useful view. A summary can show whether the assessment completed and which issues need attention. A findings list can provide specific text, evidence references, and review status. A detail view can explain one issue. Do not add a chart merely because a dashboard usually contains charts. Every visual element should help the user answer a concrete question. A large quality score without a defined method may occupy attention while hiding the information needed to make the actual decision.

Separate the saved widget definition from each generated result. Sitecore’s settings documentation distinguishes a template from the rendered result supplied with data. Use that distinction in the design. A template change can affect presentation of existing results, while a new assessment changes the data being shown. Record the references your implementation can identify, and test the relevant combinations. Do not assume that changing one resource automatically refreshes or revalidates every earlier output.

Define the input and output boundary

For the proposed review, identify the input artifact revision, intended language, assessment rubric, and selected evidence packet. A current-page title alone may not establish the assessed object. The output should retain a reference to the actual revision examined. If the user edits the draft after assessment, the interface needs a stale-result state or another explicit policy. Avoid presenting the old findings as if they describe the latest content merely because the widget remains visible in the same workspace.

Decide which values the agent may propose and which the trusted application supplies. The model can suggest findings and recommendations. A trusted component should establish authenticated actor context, verified destination identity, and the state of any authorized operation. Do not let generated data declare that a reviewer approved the result or that the current user can publish it. Keep those facts in the appropriate service or supported platform mechanism. The widget should display them only under a defined trust and refresh contract.

Write the business meaning of every status. Completed assessment, no findings, incomplete evidence, and failed assessment are different outcomes. A blank findings list should not automatically mean everything passed. It might mean that no valid result arrived. Require enough state information to distinguish those cases. The interface should explain what the user can do next: inspect evidence, provide missing context, retry an eligible assessment, or contact an owner. A reassuring empty panel is not a useful substitute for an explicit outcome.

Use a contract the team can maintain

List the field types, required values, and maximum practical content sizes for the supported interface. Choose limits based on the actual task and rendering behavior rather than importing arbitrary universal numbers. A finding should have a stable identity within the result if users can expand it or act on it. Evidence references should resolve through the supported route. Recommendations should be data, not executable instructions. Keep the contract readable enough that the agent builder and interface owner agree on its interpretation.

Define how unknown properties and unsupported status values are handled. The producer may evolve before the renderer does. A new warning category should not quietly appear as a green default because the old template lacks a matching style. The consumer can reject the result, show an unsupported-state message, or use a clearly limited fallback according to policy. The important point is explicit behavior. Do not make the renderer guess which familiar category is closest when that category affects a user’s decision.

Prepare a contract fixture before generating the full widget. Include one ordinary result, one unresolved-evidence result, and one failure. Ask the content owner whether those records contain enough information to make the intended decision. This review is cheaper than redesigning an attractive interface built around the wrong data. The admitted limitation is that a well-defined contract cannot make an unsupported finding correct. It can make the finding inspectable and keep the interface honest about the evidence and state it received.

The acceptance condition for this stage is agreement on the decision and the data needed to support it. An editor should explain what the widget describes and what it does not establish. An engineer should identify which fields are generated, observed, or authenticated. If those explanations conflict, resolve the contract before adding interactions. A widget is a product surface for a workflow decision, and the contract should express that decision clearly enough to test.

2. Define structured outputs that represent uncertainty

Keep unknown values distinct from poor results

For a proposed review score, define the measurement method and eligible population before showing a number. If the assessment lacks evidence, represent the score as unavailable with a reason. Do not substitute zero, because zero may mean a genuinely poor evaluated result. Do not substitute a favorable value to keep the layout visually complete. The UI should distinguish absence of measurement from the outcome of measurement. That distinction matters when users compare artifacts or decide whether additional review is necessary.

For each finding, retain the assessed location or field, the claim or issue, supporting evidence, and the review state. A broad message saying improve quality gives the user little to inspect. A specific finding should explain what was observed and why it matters under the rubric. If the recommendation depends on an assumption, preserve that assumption. A model can produce a useful proposal while still needing a person to confirm applicability. The contract should let the widget show that condition rather than force every finding into a definitive conclusion.

Use an explicit result status alongside the findings array. Proposed statuses might include complete, partial, failed, and unsupported. These are application examples, not native Sitecore enum values. Define what each permits the renderer to display and which actions remain available. A partial result might allow reading completed findings while preventing a consequential apply action. A failed result might retain a diagnostic reference without exposing an empty scorecard that appears successful.

Make the structured example visibly scoped

The following JSON illustrates a possible data record for the hypothetical widget. It is not a native widget definition and should not be pasted into Sitecore as a documented import format. The implementation must translate the contract into the supported schema and presentation surfaces.

{
  "contractRevision": "review-widget-data-1",
  "assessedRevisionRef": "draft-revision-12",
  "status": "partial",
  "score": null,
  "scoreUnavailableReason": "evidence_incomplete",
  "findings": [
    {
      "findingRef": "claim-4",
      "fieldRef": "summary",
      "message": "Confirm regional applicability.",
      "evidenceRefs": ["restricted-source-reference"],
      "reviewState": "needs_owner_review"
    }
  ]
}

Validate the structure before presenting the result as usable data. Use the schema vocabulary supported by the selected surface and trusted validation in the surrounding integration where needed. The JSON Schema object guidance explains required and additional-property behavior, but the standard’s full feature set should not be assumed available in every generation or widget interface. Test the rules your contract relies on and keep semantic checks separate from shape checks.

Define relationships between fields. A partial status with an unavailable score should have a reason. A finding offered for a source-based review should carry a usable evidence reference or an explicit missing-evidence state. A result describing one revision should not contain findings silently drawn from another. These business conditions may require application checks beyond primitive types. Document which component enforces them. A record that parses correctly can still contradict itself in ways that mislead the reviewer.

Keep authority-bearing values outside generated certainty

A generated recommendation to update a field should not include an authoritative approval merely because the schema has room for one. Let the trusted action service determine whether the user, destination, and packet meet the relevant policy. The widget can display a current eligibility state from that service where supported. It should not infer permission from a high score or a positive model summary. Keep the provenance of each displayed status clear enough that the user knows whether it is a recommendation, a verified observation, or an authorization decision.

Preserve identifiers across interaction. If a user expands a finding or prepares a proposed correction, refer to the finding and assessed revision rather than its current position in an array. A later regeneration may reorder findings or create a new result. The application should decide whether an old selection remains valid. Do not apply a correction to the third row merely because the user selected the third row before a new response arrived. The identity contract should survive presentation changes that do not represent the same content decision.

Separate user-edited values from regenerated values. If the widget lets a user refine a proposed correction through supported functionality, identify the new proposal and preserve any review requirement. A later assessment should not silently overwrite the user’s work without the behavior being clear and authorized. Define whether regeneration replaces the entire result, creates a new revision, or updates a specific field. The actual implementation must use the supported mechanism; this article does not assume a particular persistence or merge API.

Test the contract with contradictions and missing fields. Include an unknown status, a null score without a reason, a finding with an inaccessible source, and a result for an obsolete artifact revision. The expected behavior should be explicit rejection or a clearly limited view according to policy. My preference is a visible incomplete state over a renderer that fills gaps with plausible text. The widget should make structured uncertainty easier to understand, not conceal it behind a finished-looking card.

3. Build the widget template and test the actual result

Use the documented authoring surfaces

Sitecore’s current widget authoring guide describes creating a widget from Agentic, Widgets, providing a prompt, and inspecting Preview, JSON, Schema, Visual, and Stream views before saving. It states that creating a widget schema requires an Admin. Use the current documentation and your environment’s available UI; the broader settings guidance notes a phased rollout. Do not assume an older navigation path or an unavailable feature is present in every tenant.

Begin the authoring prompt with the intended decision and the data contract. Describe the assessed revision, findings, evidence state, and permitted display interactions. State how partial and failed results should appear. Avoid asking only for a beautiful dashboard. That leaves too much of the business meaning to visual invention. A useful prompt gives the builder enough context to produce an inspectable first draft while leaving the final structure and behavior subject to review through the supported authoring surfaces.

Inspect the generated definition rather than treating the preview as the entire artifact. Confirm that the expected fields and state distinctions are represented in the actual schema and configuration. Remove invented metrics or decorative values that are not supplied by the data contract. If the generated design adds a label implying formal approval, revise it unless the trusted process really supplies that status. A visually polished result can still introduce product claims the underlying data does not support.

Test presentation with representative records

Use fixed fixtures for the ordinary, partial, failed, and stale-result cases. Render each through the actual supported widget route. Inspect whether the title, status, findings, and evidence references remain understandable. Include long text, empty lists, and missing optional fields. Do not judge the design only with one ideal sample containing short English labels and a favorable score. The task’s expected languages and content variation should inform the fixtures you choose.

Check the hierarchy of information. The user should see what was assessed, whether the result is complete, and which issue deserves attention before interacting. Evidence should be available at the relevant finding. A summary score should not dominate a blocking unresolved condition. Choose layout and color according to meaning, and retain text labels so the interpretation is not carried solely by color. These are interface recommendations to test with users, not claims about a particular native widget component’s default behavior.

Validate rendering of generated text and links through the integration’s security model. The OWASP XSS prevention guidance explains context-specific encoding and safe handling of untrusted content. Apply the controls appropriate to the actual renderer. Do not place generated strings into executable contexts or assume JSON validity makes them safe HTML. If rich content is permitted, use the approved sanitization and rendering route and test its boundaries.

Keep HTML templates and widget definitions conceptually separate

Sitecore also documents reusable HTML templates for structured agent output. Do not infer that every widget uses the same template engine or accepts the same definition format. When an implementation separately uses Handlebars, follow the Handlebars security guidance: normal text escaping and raw-output behavior have specific meanings, and escaping is context dependent. The widget article does not require Handlebars or claim arbitrary template-engine control. Select the supported surface that actually exists in the deployment.

If a presentation template and data schema are managed separately, version their relationship in the application release record. Test an old result with a new presentation and a new result with the intended renderer. A missing warning field should not disappear silently because the template expects a newer contract. Preserve an explicit unsupported or incomplete state where the data cannot satisfy the view. The visual layer is a consumer of the contract and should receive the same compatibility attention as a content mapper.

Review the widget with the people who will use it. Ask them to identify the assessed revision, explain an unresolved finding, and locate the evidence. Observe whether a visual cue leads them to infer more certainty than the data supplies. These are proposed usability exercises, not results measured in this article. Record actual observations and revise the hierarchy accordingly. A useful interface is demonstrated by a clearer task decision, not by how closely it resembles a conventional analytics dashboard.

The acceptance condition is an actual rendered result that faithfully represents the contract across the chosen fixtures. Keep screenshots or other approved evidence of the tested states where useful under policy. State which route was tested and which features remain unavailable or unverified. Do not claim that a preview proves every action or runtime behavior. The next stage must evaluate those interactions through their own supported contracts and authorization boundaries.

4. Separate display interactions from authorized actions

Classify interactions by their effect

Separate reading details, regenerating analysis, editing a proposal, and applying a destination change. They have different consequences and may need different permissions. A detail expansion can remain local to the displayed result. Regeneration creates a new assessment whose relationship to user edits must be defined. A destination write is a consequential operation that needs an authenticated action path. Do not give every control the same generic Apply label. The user should understand what changes and what remains a proposal.

For the hypothetical review widget, start with viewing evidence and preparing a correction packet. If the supported environment permits an action integration, add it only after defining its inputs, identity, and expected result. This article does not invent a native callback name or arbitrary JavaScript execution hook. Where the selected widget surface cannot perform a required action directly, use the supported surrounding workflow or a manual handoff. A clear handoff is preferable to presenting a button whose actual effect is undocumented or unavailable.

Keep action targets trusted. A generated finding may suggest that a particular field needs correction, but the execution service should resolve and validate the destination under the authenticated context. Do not accept an arbitrary generated destination as permission to write there. The same principle applies to external URLs or recipients. An interaction can begin with generated data while the actual effect remains constrained by the approved workflow scope. Verify the resource boundary at execution rather than inferring it from what the widget displays.

Bind consequential actions to a reviewed proposal

For an update, prepare a packet identifying the exact artifact revision, destination, proposed field assignments, and required evidence. A human decision should refer to that packet under the organization’s policy. The action service should confirm that the effect being executed still matches the decision. Do not use a high score or positive recommendation as an approval substitute. If the user edits the proposal, create the appropriate new revision and determine whether the existing review remains valid under explicit rules.

Check for stale results before applying a change. The source artifact or destination may have changed since assessment. Use a documented conditional mechanism where supported, or a controlled process that states the remaining race limitation. The admitted limitation is that a visual stale-state check cannot by itself make a remote write atomic. A widget can warn the user and supply the right context, but the trusted execution path must enforce the actual contract available from the destination.

Treat a denied action as a meaningful state. Explain whether the issue is missing authority, an outdated packet, a changed target, or an unavailable dependency. Do not hide the denial behind a generic failure that encourages repeated clicking. Preserve a restricted diagnostic reference for operators and a clear next step for the user. The UI should support resolution of the actual condition. It should not ask the model to rewrite the request until an authorization check happens to accept a different-looking payload.

Handle repeated clicks and uncertain outcomes

A disabled button can reduce accidental repeats in the visible interface, but it is not the whole deduplication design. The action service needs operation identity and documented repeat behavior appropriate to the effect. If a response is lost after submission, the widget should show an uncertain or awaiting-verification state rather than invite a blind repeat. The integration should reconcile through supported evidence. Do not claim that a browser loading spinner prevents duplicate remote effects after reconnects or multiple clients.

Define what success means. A request accepted by a service may not establish that the intended content is stored or released. Show accepted, verified, and completed states according to the actual provider contract. A confirmation message should describe the evidence available. If the user must inspect a destination preview or wait for another workflow decision, make that next step visible. Avoid telling them that everything is live when the action only created a draft or submitted work for review.

Keep regenerated analysis separate from pending actions. If a new result arrives while an older correction is awaiting approval or verification, identify which result each action belongs to. Do not let the newest display overwrite the reference needed to explain an in-flight operation. The user should be able to distinguish current analysis from the packet being executed. This relationship can live in the supported workflow or integration record; the widget should present it in a way that does not blur revisions.

Test the interaction boundary with a changed destination, an unauthorized role, a repeated submission, and a lost response. Use disposable data and the actual supported action route. Assert the business outcome and the displayed state, not merely that the button handler returned. My preference is to release a read-and-review widget first, then add a narrowly scoped action after these boundaries are tested. That sequence gives users useful structured output without asking a visual prototype to carry authority it has not demonstrated.

5. Design failure, accessibility, and streaming states

Design incomplete execution as an ordinary state

Specify what the user sees before valid data arrives. A loading state should describe the task and preserve context about the assessed artifact. A partial result should indicate which portions are available and which are incomplete. A failed assessment should not look like a completed result with no findings. A cancelled or superseded run should remain distinguishable from a current result. These states should be part of the contract and fixture set, not improvised after a production request stalls.

The documented Stream view lets authors test the widget outcome while it executes. Use it to observe the supported behavior, but do not infer a particular transport protocol or partial-JSON merge contract from the word Stream. Establish what the actual runtime exposes. If the interface supplies only complete valid records, design around that boundary. If it exposes incremental results, define and test how partial content becomes a valid displayed state. The article does not assume arbitrary event handling or token-level control.

Avoid presenting transient values as final observations. A score that appears before the evidence assessment finishes can influence a decision even if it changes later. Keep consequential actions unavailable until the trusted eligibility conditions are satisfied. A partial findings list can still be useful if its incompleteness is clear. The design should tell users whether they are reading provisional analysis or a completed packet. Do not rely on a subtle spinner to communicate a distinction that affects authorization or editorial judgment.

Make the interaction usable without a mouse

Test keyboard access through the actual rendered surface. Users should be able to reach controls, understand their names, and see focus. The W3C button pattern describes expected activation and focus behavior. The broader keyboard interface guidance explains why custom ARIA widgets need implemented keyboard behavior. Use supported native controls where appropriate and verify the rendered result rather than assuming a role attribute supplies the complete interaction.

Give controls names that describe their effect. View evidence, prepare correction, and request a new assessment communicate different actions. If a control opens a dialog or a detail surface, test where focus moves and how the user returns. When a result refreshes, preserve a predictable reading and focus position where the supported surface allows it. Do not move focus simply because the model produced another chunk of text. The user should retain control of their task while the interface updates.

Use text to communicate status alongside visual treatment. A red or green accent alone should not be the only way to distinguish unresolved evidence from a completed check. Make the result’s meaning available to the users and assistive technologies supported by the deployment. Test the actual markup and interaction with appropriate tools and users. This article does not claim conformance from a visual inspection or from one keyboard pass. Accessibility is a product requirement with its own evidence and known limits.

Test recovery and layout variation

Include long labels, expanded findings, empty evidence lists, and the languages relevant to the workflow. Test the container sizes and zoom conditions the product supports. A fixed-height scorecard that hides the unresolved issue may be unsuitable even if it looks balanced in one preview. Prefer layouts that preserve the task hierarchy under content variation. If the supported widget system limits layout control, document the constraint and choose a design that remains understandable within it.

When execution fails, show a next step appropriate to the cause. Missing context should ask for the relevant information through the supported route. A transient read failure may permit a bounded retry. An uncertain consequential action requires verification or reconciliation, not a generic regenerate button. Keep the diagnostic reference linked to the actual run or operation. Avoid exposing raw credentials, internal stack traces, or unnecessary source material in the user-facing error view.

Test reconnect and supersession behavior. A user may leave the surface and return while a newer assessment exists. The widget should identify the result it displays and whether it remains current under the application’s policy. If the native interface manages persistence differently from the proposed design, adapt to the documented capability rather than inventing a browser-local guarantee. Preserve the evidence needed to explain an action taken from an earlier result, especially when that action continues after the visible assessment changes.

The acceptance exercise should give a user a partial assessment, a keyboard-only task, and a failed action. Ask them to identify what is known and choose the correct next step. Give an operator the corresponding diagnostic references and ask them to locate the relevant evidence. Record actual observations when the team performs the exercise. A widget is ready for broader use when its nonideal states support the intended decision as clearly as its attractive completed state, within the scope the tests actually cover.

Use a synthetic walkthrough to check that these states fit together. The user opens a partial review for a draft, expands one finding, and sees that its evidence is unresolved. A newer assessment then completes for a changed draft revision. The interface should identify that new result and avoid treating the user’s old selection as a correction for the new text. If an earlier action is already awaiting verification, keep that operation’s packet reference visible through the supported surrounding process. This fixture tests revision identity across ordinary interaction rather than assuming every refresh is equivalent to the same decision.

Ask the user what they believe happened at each point. Did the system only analyze the draft, prepare a proposal, submit a request, or verify a stored change? Compare that interpretation with the actual operation record. A mismatch is a product defect to resolve even if every technical request returned successfully. The status language should communicate the evidence the system has, especially when an attractive completed card could imply a stronger outcome.

6. Version and release the widget as a product surface

Release the schema, view, and action contract together

Treat the widget as a product surface with connected components. The agent produces data, the schema describes expected structure, the view interprets meaning, and any action service performs effects. A change to one can invalidate assumptions in another. Maintain a release record for the components the application controls and identify the supported combinations. Do not assume that a visual-only change is harmless if it hides warnings or changes how users interpret a recommendation.

Version the data contract and preserve representative fixtures. Include old saved results when the widget can display them after an update. A new renderer should not silently reinterpret an unknown status as success. A new producer should not emit a field whose meaning the current action service guesses. Use explicit adaptation or an unsupported-result state according to policy. The release owner should know which combinations are allowed and what happens when a result arrives from another contract revision.

Keep action eligibility independent of display convenience. If a new layout removes an approval summary, it does not remove the underlying review requirement. If a template adds a button, it does not automatically grant a corresponding service capability. Review the actual permission and operation scope before exposing the control. The display should reflect trusted eligibility and explain denials, while the action service enforces its own contract. A consistent interface is useful, but it should not become the only place a consequential rule exists.

Use a bounded rollout and concrete feedback

Start with one content-review task and a limited audience. A read-and-review release can establish whether users understand findings and evidence before the team adds destination writes. Collect feedback about decisions: which issues users could locate, what uncertainty they misunderstood, and where they needed more context. These are proposed evaluation questions, not results observed here. Use actual findings to revise the contract or hierarchy rather than add more decorative widgets in response to general requests for a richer dashboard.

Measure the right outcomes. Suggested measures include successful evidence inspection, unresolved questions carried into review, action denials by cause, and corrections completed under the intended packet. Define the unit and population before reporting a rate. A click count alone does not establish useful review, and a low denial count may simply mean the workflow is permissive. Inspect representative cases with the content owner. The purpose is to improve the user’s decision and the integrity of the action path, not maximize interaction volume.

Assign owners for data quality, presentation, and operations. A misleading score may belong to the assessment design. A hidden warning may belong to the renderer. A denied write may belong to authorization or stale data. Route problems to the component that can correct them. Avoid treating every issue as a prompt problem or every user complaint as a request for a new visual style. The widget’s value depends on the whole decision path, and each part needs an accountable maintainer.

Plan rollback and support for existing results

A rollback should consider stored data as well as configuration. Restoring an older view may not make new result records compatible with it. A changed action contract may leave work in progress. Identify those cases before release and preserve the references needed to inspect them. Use the supported platform and integration mechanisms for restriction or correction. Do not assume that hiding the widget cancels an already issued remote action. Operators should know what can still be in flight.

Prepare a short support guide around common states. Explain how to identify the assessed revision, locate evidence, request a new assessment, and investigate an uncertain action. Use actual interface references and permissions from the implementation. Ask someone outside the builder team to follow the guide with a stale result and a denied operation. Their questions reveal whether the labels and records support ordinary handoff. Improve the evidence path rather than relying on private knowledge from the person who wrote the original prompt.

Before broad release, require contract fixtures, rendered-state checks, keyboard evidence, and tested action boundaries for any consequential operation. State which features are supported in the actual tenant and which remain manual or unavailable. The article’s examples are a design to implement and verify, not a claim that this complete widget has already been built in SitecoreAI. That boundary matters because an authoring preview can demonstrate presentation while leaving integration behavior untested.

The immediate task is to choose one agent result and write the decision contract for it. Identify the assessed object, the evidence a user needs, the uncertainty states, and the next action the interface should support. Build the smallest widget that represents those facts faithfully through the documented authoring surfaces. Test its ordinary and incomplete states before adding automation. A useful interactive result begins with structured information people can trust enough to inspect, then earns additional actions through explicit contracts and evidence.
