  - knowledge_sources: "<it_kb_sys_id>,<hr_kb_sys_id>"
  - enable_rag: true
  - response_mode: "generative"
  - fallback_action: "create_incident"

Context options for Now Assist skills:

Step 3: Configure Knowledge Sources

Link knowledge bases to the Q&A skill for grounded responses.

MCP Approach:

Use SN-Query-Table on kb_knowledge_base:
  - query: active=true
  - fields: sys_id,title,description,kb_version
  - limit: 20

Associate knowledge bases with the skill:

Use SN-Create-Record on sn_now_assist_skill_config:
  - skill: "<qa_skill_sys_id>"
  - name: "knowledge_source_1"
  - config_type: "knowledge_base"
  - value: "<kb_sys_id>"
  - active: true
  - order: 100

Use SN-Create-Record on sn_now_assist_skill_config:
  - skill: "<qa_skill_sys_id>"
  - name: "knowledge_source_2"
  - config_type: "knowledge_base"
  - value: "<hr_kb_sys_id>"
  - active: true
  - order: 200

Configure knowledge filtering:

Use SN-Create-Record on sn_now_assist_skill_config:
  - skill: "<qa_skill_sys_id>"
  - name: "kb_filter"
  - config_type: "knowledge_filter"
  - value: "workflow_state=published^valid_to>=javascript:gs.now()"
  - active: true

Step 4: Configure LLM Parameters

Set up the generative AI parameters for response generation.

MCP Approach:

Use SN-Create-Record on sn_gen_ai_config:
  - name: "Now Assist Q&A LLM Config"
  - description: "LLM parameters for Now Assist Q&A responses"
  - active: true
  - llm_provider: "now_llm"
  - model: "default"
  - temperature: 0.3
  - max_tokens: 400
  - top_p: 0.9
  - frequency_penalty: 0.1

  "name": "Now Assist Q&A LLM Config",
  "active": true,
  "llm_provider": "now_llm",
  "temperature": 0.3,
  "max_tokens": 400,
  "top_p": 0.9
}

Link LLM config to skill:

Use SN-Create-Record on sn_now_assist_skill_config:
  - skill: "<qa_skill_sys_id>"
  - name: "llm_config"
  - config_type: "gen_ai_config"
  - value: "<gen_ai_config_sys_id>"
  - active: true

Step 5: Configure System Prompts

System prompts guide LLM behavior for Q&A responses.

MCP Approach:

Use SN-Create-Record on sn_now_assist_skill_config:
  - skill: "<qa_skill_sys_id>"
  - name: "system_prompt"
  - config_type: "prompt"
  - value: |
      You are an IT support assistant for {company_name}. Your role is to help agents
      find answers to technical questions using the provided knowledge base content.

      Guidelines:
      - Only answer based on the provided context. Do not make up information.
      - If the context does not contain a clear answer, say "I don't have enough
        information to answer this question" and suggest creating a knowledge article.
      - Always cite the source knowledge article by title.
      - Keep answers concise and actionable, using bullet points for steps.
      - If the question involves a specific incident, reference relevant fields.
      - Never reveal internal system details, credentials, or sensitive data.
  - active: true

Prompt template variables:

Step 6: Configure Now Assist Panel

Set up where and how the Now Assist panel appears.

MCP Approach:

Use SN-Create-Record on sn_now_assist_panel_config:
  - name: "Agent Workspace Q&A Panel"
  - description: "Now Assist Q&A panel for IT agent workspace"
  - active: true
  - context: "agent_workspace"
  - skills: "<qa_skill_sys_id>"
  - position: "right_sidebar"
  - auto_open: false
  - show_feedback: true
  - show_sources: true
  - max_conversation_turns: 10
  - greeting_message: "Hi! I can help you find answers from our knowledge base. What would you like to know?"

REST Approach:

POST /api/now/table/sn_now_assist_panel_config
Body: {
  "name": "Agent Workspace Q&A Panel",
  "active": true,
  "context": "agent_workspace",
  "skills": "<qa_skill_sys_id>",
  "position": "right_sidebar",
  "show_feedback": true,
  "show_sources": true
}

Step 7: Configure Conversation Context

Set up how conversation context is managed for multi-turn dialogues.

MCP Approach:

Use SN-Create-Record on sn_now_assist_skill_config:
  - skill: "<qa_skill_sys_id>"
  - name: "context_config"
  - config_type: "context"
  - value: '{
      "max_history_turns": 5,
      "include_record_context": true,
      "record_fields": ["short_description", "description", "priority", "category", "assignment_group"],
      "context_window_tokens": 3000,
      "clear_on_record_change": true
    }'
  - active: true

Step 8: Set Up Response Quality Guardrails

MCP Approach:

Use SN-Create-Record on sn_now_assist_skill_config:
  - skill: "<qa_skill_sys_id>"
  - name: "guardrails"
  - config_type: "safety"
  - value: '{
      "require_knowledge_grounding": true,
      "min_confidence_score": 0.65,
      "block_pii_in_response": true,
      "max_response_length": 500,
      "prohibited_topics": ["salary", "termination", "legal_advice"],
      "fallback_message": "I am not able to answer this question. Please contact your IT service desk for assistance.",
      "enable_content_filtering": true
    }'
  - active: true

Step 9: Activate and Deploy

MCP Approach:

Use SN-Update-Record on sn_now_assist_skill:
  - sys_id: "<qa_skill_sys_id>"
  - status: "published"
  - active: true

Verify configuration is complete:

Use SN-Query-Table on sn_now_assist_skill_config:
  - query: skill=<qa_skill_sys_id>^active=true
  - fields: name,config_type,active
  - limit: 20

Verify panel is active:

Use SN-Query-Table on sn_now_assist_panel_config:
  - query: skills=<qa_skill_sys_id>^active=true
  - fields: name,context,position,active

Step 10: Monitor and Tune Response Quality

Query feedback data:

Use SN-Query-Table on sn_now_assist_feedback:
  - query: skill=<qa_skill_sys_id>^sys_created_on>javascript:gs.daysAgo(7)
  - fields: sys_id,query,response,rating,feedback_text,user
  - limit: 50
  - orderBy: sys_created_on
  - orderDirection: desc

Analyze negative feedback patterns:

Use SN-Query-Table on sn_now_assist_feedback:
  - query: skill=<qa_skill_sys_id>^rating<3
  - fields: query,response,rating,feedback_text
  - limit: 20

Adjust based on feedback:

Use SN-Update-Record on sn_gen_ai_config:
  - sys_id: "<gen_ai_config_sys_id>"
  - temperature: 0.2
  - max_tokens: 500

Tool Usage

Best Practices

1. Start with a single knowledge base and expand sources incrementally as quality is validated
2. Use low temperature (0.2-0.4) for Q&A to keep responses factual and grounded
3. Write specific system prompts that define the assistant's role, boundaries, and response format
4. Enable citation display so users can verify answers against source material
5. Set confidence thresholds conservatively (0.65+) and adjust based on feedback
6. Include record context when the Q&A skill is used alongside incidents or cases
7. Limit conversation history to 5-7 turns to manage token usage and context relevance
8. Block PII in responses to prevent accidental exposure of sensitive data
9. Monitor feedback weekly and address patterns of negative ratings promptly
10. Test with real user queries from support tickets to validate response quality before launch
