Overview

The Optimize GRC Issue Resolution use case works out of the box, but every organization has different data volumes, resolution patterns, and process expectations. This article covers every supported customization — from tuning which past issues are used as reference data, to adjusting how the action plan and remediation tasks are generated, and modifying agent behavior and messaging.

The two agents and their skills are accessed from:

Usecase: All → Now Assist AI Agents → AI Use Cases

Skills: All → Now Assist Skill Kit → Skill
Indexed Sources: All → Indexed Sources

1. Adjusting Which Issues Are Used as Reference Data

The action plan generation only draws from issues that are closed. By default, this means issues in Closed Complete or Closed Incomplete state. You can change this filter to expand or narrow the pool of reference issues.

Navigate to

All → Indexed Sources → search for GRC issues → open → find the Issue closed filter condition → edit.

Current filter

state = 3 (Closed Complete) OR state = 4 (Closed Incomplete)

What you can safely change

- Add additional closed states if your organization uses custom issue states

- Add further conditions to narrow the pool — for example, restrict to issues from a specific category or assigned group

Tradeoff: A broader filter increases the pool of reference issues and can improve plan quality — but only if those issues have meaningful action plans and remediation tasks. Issues without action plans or linked tasks are automatically excluded at runtime even if they pass the filter, so adding more states with poor data quality will not help. A narrower filter may leave too few relevant matches for sparse datasets.

2. Adjusting the Similarity Threshold

The similarity threshold controls how closely a past issue must match the current one before it is included in the comparison set. The default is 80%. A past issue that scores below this threshold is excluded regardless of how many results are available.

Navigate to

All → Now Assist Skill Kit → Skill → search for Issue Action Plan Generation → open → Tools → open GetSimilarRecords tool → edit the script.

Example snippet

var SCORE_THRESHOLD = 0.80;  // default — lower to include more results, raise for stricter matching

Value	Effect
0.70	More past issues included — useful when data is sparse but may introduce loosely related patterns
0.80 (default)	Balanced for most environments
0.90	Only very closely matched issues included — higher precision but may return nothing on new issue types

Tradeoff: Lowering the threshold increases the number of reference issues but risks introducing irrelevant patterns into the generated plan. Raising it improves precision but may result in no plan being generated if your historical data is limited. Test against real issues in your instance before deploying.

3. Adjusting the Number of Past Issues Retrieved

By default, up to 20 past issues are retrieved and passed to the AI model for synthesis. All retrieved issues must also meet the similarity threshold — so the actual number sent to the model may be lower.

Navigate to

All → Now Assist Skill Kit → Skill → search for Issue Action Plan Generation → open → Tools → open GetSimilarRecords tool → edit the script.

Example snippet

var MATCH_COUNT = 20;  // default — increase for richer synthesis, decrease to reduce latency

Tradeoff: A higher count gives the AI model more patterns to synthesize from, which can improve plan quality when your historical data is rich and varied. However, each retrieved issue includes its full action plan and all linked remediation tasks — a higher count increases the size of the prompt sent to the model and can slow response time. Keep the value within a reasonable range for your data volume.

4. Editing Agent Instructions

Each agent has its own instruction set that controls its conversational behavior — the messages it displays, how it presents options to the user, and how it handles each user choice. These are separate from the skill prompts and can be updated independently.

Issue Action Plan AI Agent

Navigate to:
All → Now Assist AI Agents → AI Agents → search for Issue action plan AI agent → open → edit the Instructions field.

Part	What you can change
Accept / Edit / Dismiss prompt	The wording of the options presented to the user after the action plan is shown
Acceptance message	What the agent says when the user accepts — including the note about the plan being saved to the issue record
Dismissal message	What the agent says when the user dismisses — currently tells the user to populate the plan manually
Edit refinement behavior	How the agent asks for and incorporates feedback when the user chooses to edit
Error messages	What the agent says when the issue record cannot be found or the plan cannot be generated

Remediation Tasks AI Agent

Navigate to:
All → Now Assist AI Agents → AI Agents → search for Remediation tasks AI agent → open → edit the Instructions field.

Part	What you can change
Accept / Edit / Dismiss prompt	The wording of the options presented after task suggestions are shown
Task display format	How suggested tasks are displayed when the user edits — currently uses a Name / Description format
Acceptance message	The confirmation message after tasks are created — currently tells the user to assign owners manually
Dismissal message	What the agent says when the user dismisses — currently tells the user to create tasks manually from the issue page

Tradeoff: The LLM is sensitive to instruction wording. Changes to how options are presented or how feedback is collected can affect agent behavior in non-obvious ways. Always test with a range of real issue scenarios before saving changes to production.

5. Enriching the Search Query with Additional Issue Details

The search query is what drives semantic matching against historical issues. By default, the GetSimilarRecords tool searches using the current issue's short_description — and optionally includes description when the use_description input is enabled. Adding more context from the issue record — such as entity name, issue type, or custom fields — can improve the relevance of the historical matches returned.

Navigate to

All → Now Assist Skill Kit → Skill → search for Issue Action Plan Generation → open → Tools → open GetSimilarRecords tool → edit the script.

Current code — how the search query is built

var shortDescription = '';
var issueId = '';
if (issueGR.next()) {
    shortDescription = issueGR.getValue("short_description");
    if (inputs.use_description === 'true') {
        shortDescription += "\n" + issueGR.getValue("description");
    }
    issueId = issueGR.getValue("sys_id");
}
var references = getReferences(issueId, shortDescription,
    ['short_description', 'description'], ['body']);

Modified code — enrich the query with entity and issue type

var shortDescription = '';
var issueId = '';
if (issueGR.next()) {
    shortDescription = issueGR.getValue("short_description");
    if (inputs.use_description === 'true') {
        shortDescription += "\n" + issueGR.getValue("description");
    }

    // Enrich the search query with additional issue context
    var entityName = issueGR.getDisplayValue("profile");
    var issueTypeLabel = issueGR.getDisplayValue("issue_type");
    if (entityName) {
        shortDescription += "\nEntity: " + entityName;
    }
    if (issueTypeLabel) {
        shortDescription += "\nIssue Type: " + issueTypeLabel;
    }

    issueId = issueGR.getValue("sys_id");
}
var references = getReferences(issueId, shortDescription,
    ['short_description', 'description'], ['body']);

What you can safely change

- Add any field from the sn_grc_issue record to the query string — use getDisplayValue() for reference fields to include the display name rather than the sys_id

- Include custom fields your organization has added to the issue table

- Adjust or remove the \n separator — the semantic search treats the entire string as context, so the separator style has minimal impact

Tradeoff: Adding relevant context (like entity name or issue type) helps the semantic search find more precisely related historical issues. However, adding too many fields or irrelevant data can dilute the query and reduce match quality. Start with one or two additional fields and test against real issues to measure improvement.

6. Adding Dynamic Filters to RAG Search

By default, the RAG search returns all closed issues that match the search profile's static filter (state=3^ORstate=4). If your organization needs to narrow results further at runtime — for example, to only compare against issues of the same type or issues related to a specific entity — you can add dynamic filter conditions using the .condition() method on the RAGRetrievalSource.

Navigate to

All → Now Assist Skill Kit → Skill → search for Issue Action Plan Generation → open → Tools → open GetSimilarRecords tool → edit the script.

Current code — source construction without dynamic filters

request.sources([
    new sn_search.RAGRetrievalSource()
        .sourceTableName('sn_grc_issue')
        .fields(FIELDS)
        .filter(true)
]);

Example — filter by the current issue's type

This restricts results to historical issues that share the same issue type as the current issue. You will need to pass the issue type value into the getReferences function.

Step 1: Extract the issue type and pass it to getReferences

// After querying issueGR, extract the issue type
var issueType = issueGR.getValue("issue_type");

// Pass it as an additional parameter
var references = getReferences(issueId, shortDescription,
    ['short_description', 'description'], ['body'], issueType);

Step 2: Update the getReferences function signature and source construction

function getReferences(issueId, shortDescription, fields, indexNames, issueType) {
    ...
    request.sources([
        new sn_search.RAGRetrievalSource()
            .sourceTableName('sn_grc_issue')
            .fields(FIELDS)
            .filter(true)
            .condition('issue_type=' + issueType)
    ]);
    ...
}

Example — filter by a fixed set of issue types

To restrict results to a specific group of issue types (for example, all control-related types), use an encoded query with ^OR conditions:

request.sources([
    new sn_search.RAGRetrievalSource()
        .sourceTableName('sn_grc_issue')
        .fields(FIELDS)
        .filter(true)
        .condition('issue_type=7^ORissue_type=8^ORissue_type=9^ORissue_type=11')
]);

Example — filter by entity

To only match historical issues from the same entity as the current issue:

var entitySysId = issueGR.getValue("profile");

request.sources([
    new sn_search.RAGRetrievalSource()
        .sourceTableName('sn_grc_issue')
        .fields(FIELDS)
        .filter(true)
        .condition('profile=' + entitySysId)
]);

Example — combine multiple filter conditions

Dynamic conditions follow GlideRecord encoded query syntax. You can combine conditions using ^ (AND) and ^OR (OR):

var entitySysId = issueGR.getValue("profile");
var issueType = issueGR.getValue("issue_type");

request.sources([
    new sn_search.RAGRetrievalSource()
        .sourceTableName('sn_grc_issue')
        .fields(FIELDS)
        .filter(true)
        .condition('profile=' + entitySysId + '^issue_type=' + issueType)
        .validateWithSearchProfile(true)
]);

Note: The .condition() method adds a runtime filter on top of the search profile's existing filter. The static filter (state=3^ORstate=4) still applies — your dynamic condition narrows results further, it does not replace the base filter. Adding .validateWithSearchProfile(true) ensures the source configuration is validated against the search profile.

What you can safely change

- Filter by any field on the sn_grc_issue table — common choices include issue_type, profile (entity), and assigned_to

- Use hardcoded values for fixed filters (e.g., always restrict to control-related issues) or dynamic values from the current issue record for contextual filters

- Combine multiple conditions using encoded query syntax (^ for AND, ^OR for OR)

Tradeoff: Dynamic filters improve relevance by restricting matches to a comparable subset of historical issues. However, overly narrow filters — especially on instances with limited historical data — may result in too few or no matches. When the agent finds no similar records, no action plan can be generated. Test with representative issues to ensure your filters leave an adequate pool of reference data.

Raise similarity threshold	Only closely matched issues inform the plan	May return no results for new or uncommon issue types
Increase match count	Richer synthesis from more historical context	Larger prompt sent to LLM; slower response time
Edit agent instructions	Tailor messages and flow to your org's tone and process	LLM is sensitive to wording — test thoroughly before deploying
Enrich search query	More relevant historical matches when additional context is included	Overly long queries may dilute semantic matching precision
Add dynamic filters	Results restricted to a comparable subset of historical issues	Overly narrow filters may return too few matches on sparse datasets

⚠ Important: Testing and Upgrade Compatibility

All customizations described in this article modify components that are part of the out-of-the-box use case delivery. Before deploying any change to production, test thoroughly in a sub-production instance using a representative set of real issue records — including issues with rich action plans, sparse action plans, and no historical matches.

When ServiceNow ships upgrades to this use case — including changes to skill prompts, agent instructions, datasource scripts, or indexed source configuration — those updates will reflect the out-of-the-box defaults. Any customizations you have made will need to be reviewed, reconciled, and re-applied against the upgraded version. This includes:

Filter changes on the GRC issues indexed source
Threshold and match count changes in the GetSimilarRecords tool script
Search query enrichments in the GetSimilarRecords tool script
Dynamic filter conditions in the GetSimilarRecords tool script
Instruction changes in either agent

Maintain clear documentation of every customization your organization applies, including the original out-of-the-box value and the reason for the change, to make upgrade reconciliation straightforward.
