Incident Activity Summarization

Overview

This skill generates concise narrative summaries of incident activity streams for ServiceNow ITSM:

• Consolidating work notes, additional comments, and journal entries into a coherent timeline
• Tracking state transitions with timestamps, durations, and responsible parties
• Mapping assignment changes across groups and individuals
• Highlighting key decision points, escalation triggers, and resolution attempts
• Generating handoff-ready summaries for shift changes and team transitions
• Creating management-friendly executive narratives for major incidents
• Producing SLA-aware summaries that flag breaches and at-risk timelines

When to use: When agents need to quickly understand an incident's history during handoff, when managers need status updates on active incidents, when producing post-incident documentation, or when building zero-touch service desk automation that auto-summarizes activity.

Prerequisites

• Roles: itil, incident_manager, or admin
• Plugins: com.glideapp.itil (ITSM)
• Access: Read access to incident, sys_journal_field, sys_audit, task_sla
• Knowledge: Incident lifecycle states, SLA concepts, assignment group structure
• Related Skills: itsm/incident-lifecycle for state management, itsm/major-incident for P1 processes

Step 6: Build the Activity Timeline

Merge all data sources into a unified chronological timeline:

=== INCIDENT ACTIVITY TIMELINE ===
Incident: INC0067890 - Production database connection pool exhaustion
Priority: P1 - Critical | State: Resolved
Duration: 4 hours 23 minutes (Opened to Resolved)

[2025-12-10 02:15] OPENED by Monitoring System (auto-created)
  - Source: Event Management alert
  - Description: Connection pool on prod-db-01 exceeded 95% threshold
  - Auto-assigned to: Database Administration (DBA Team)

[2025-12-10 02:17] WORK NOTE by System
  - "Related alert: CPU utilization on prod-db-01 at 92%"
  - "3 dependent services affected: Order Processing, User Auth, Reporting"

[2025-12-10 02:25] STATE: New -> In Progress
  - Assigned to: Mike Chen (DBA Team)
  - Work note: "Investigating connection pool metrics. Current active
    connections: 485/500. Identifying top consumers."

[2025-12-10 02:42] WORK NOTE by Mike Chen
  - "Root cause identified: Reporting batch job spawning excessive connections.
    Job ID: RPT-NIGHTLY-2025121001. Normally runs 50 connections, currently
    holding 280 connections due to long-running query."

[2025-12-10 02:55] ESCALATION triggered (P1 > 30 min without resolution)
  - Notification sent to: DBA Manager (Sarah Kim)

[2025-12-10 03:10] WORK NOTE by Mike Chen
  - "Killed the runaway reporting query (PID 45678). Connection pool
    dropping. Currently at 310/500. Waiting for connections to release."

[2025-12-10 03:15] COMMENT by Sarah Kim (Manager)
  - "Monitoring the situation. Is there a risk of recurrence tonight?"

[2025-12-10 03:20] WORK NOTE by Mike Chen
  - "Disabled the nightly reporting job to prevent recurrence. Will
    coordinate with Reporting team to fix the query before re-enabling.
    Connection pool now at 180/500 - within normal range."

[2025-12-10 03:45] WORK NOTE by Mike Chen
  - "All dependent services confirmed operational. Order Processing,
    User Auth, and Reporting dashboard all responding normally."

[2025-12-10 04:00] ASSIGNMENT changed: Mike Chen -> Lisa Park (for monitoring)
  - Shift handoff: Mike Chen end of on-call rotation

[2025-12-10 06:38] STATE: In Progress -> Resolved
  - Resolved by: Lisa Park
  - Resolution: "Runaway reporting query killed, connection pool restored.
    Nightly job disabled pending query optimization. Change CHG0012345
    created for permanent fix."

Step 7: Generate Narrative Summary

Convert the timeline into a readable narrative:

=== NARRATIVE SUMMARY ===
Incident INC0067890 was a P1 critical issue involving production database
connection pool exhaustion on prod-db-01. The incident was auto-created
by Event Management at 02:15 on December 10, 2025, when the connection
pool exceeded the 95% threshold.

DBA team member Mike Chen began investigation at 02:25 and identified
the root cause within 17 minutes: a nightly reporting batch job had
spawned 280 connections (normally 50) due to a long-running query. Three
dependent services were impacted: Order Processing, User Auth, and
Reporting.

The runaway query was terminated at 03:10, and the connection pool
returned to normal levels (180/500) by 03:20. The nightly reporting job
was disabled as a preventive measure. All dependent services were
confirmed operational by 03:45.

The incident was handed off to Lisa Park at 04:00 during shift rotation
and formally resolved at 06:38. Total resolution time was 4 hours 23
minutes. A change request (CHG0012345) was created for the permanent
fix (query optimization).

KEY METRICS:
- Time to Acknowledge: 10 minutes
- Time to Root Cause: 27 minutes
- Time to Mitigate: 55 minutes
- Time to Resolve: 4 hours 23 minutes
- Reassignment Count: 1 (shift handoff)
- SLA Status: Response SLA met, Resolution SLA met

Step 8: Generate Handoff Summary

Create a condensed summary optimized for shift handoffs:

=== SHIFT HANDOFF SUMMARY ===
Incident: INC0067890 - DB Connection Pool Exhaustion (P1)

CURRENT STATE: Resolved (monitoring)
WHAT HAPPENED: Reporting batch job consumed 280 DB connections (limit 500),
  causing service degradation for 3 dependent apps.
WHAT WAS DONE: Killed runaway query, disabled nightly job, pool recovered.
WHAT REMAINS: Monitor for recurrence. Reporting job stays disabled until
  CHG0012345 (query optimization) is implemented.
RISK: Low - root cause addressed. If pool spikes again, kill reporting
  connections first (see work note at 02:42 for query identification steps).
CONTACTS: Mike Chen (original responder), Sarah Kim (manager, notified).

Step 9: Generate Executive Summary

Create a management-friendly overview:

=== EXECUTIVE SUMMARY ===
INC0067890 | P1 Critical | RESOLVED

A production database capacity issue caused temporary degradation to three
business services (Order Processing, User Authentication, Reporting) for
approximately 90 minutes on December 10. The issue was caused by a
misconfigured batch reporting job and was resolved without data loss or
customer impact. A permanent fix is scheduled via change request CHG0012345.

Impact: 3 internal services, no customer-facing impact
Duration: 90 minutes (service degradation), 4h23m (total incident lifecycle)
Root Cause: Software defect in reporting batch job
Prevention: Change request filed for query optimization

Step 10: Attach Summary to Incident

Save the generated summary as a work note.

MCP Approach:

Tool: SN-Add-Work-Notes
Parameters:
  table_name: incident
  sys_id: <incident_sys_id>
  work_notes: "[AI-Generated Activity Summary]\n\n<narrative summary>"

Tool Usage

Tool	Purpose	When to Use
SN-Get-Record	Retrieve incident record details	Initial context gathering
SN-Query-Table	Fetch journal entries, audit trail, SLA records	Activity data retrieval
SN-Natural-Language-Search	Find related incidents by description	Cross-incident pattern analysis
SN-Add-Work-Notes	Attach generated summary to incident	Documentation and handoff

Best Practices

1. Merge all data sources chronologically -- work notes, state changes, and assignments in one timeline
2. Distinguish work notes from comments -- work notes are internal, comments are customer-visible
3. Calculate time-in-state -- show how long the incident spent in each state
4. Highlight root cause clearly -- the most important finding should be prominent
5. Include what remains to be done -- handoff summaries must cover outstanding actions
6. Flag SLA breaches prominently -- breaches should be visible at the top of any summary
7. Use business-friendly language -- executive summaries should avoid technical jargon
8. Note reassignment patterns -- excessive reassignments indicate routing issues
9. Include related records -- link to change requests, problem records, or related incidents
10. Timestamp all entries -- every activity must have a clear timestamp for audit purposes

Troubleshooting

Issue	Cause	Resolution
Journal entries missing	Retention policy purged old entries	Check sys_journal_field retention; data may be in archive
Audit records incomplete	Auditing not enabled for all fields	Verify audit configuration in sys_dictionary
State changes not tracked	State field not audited	Enable auditing on the state field in dictionary
SLA records missing	No SLA definitions for this priority/category	Check SLA definitions in contract_sla
Assignment history gaps	Assignment changes not audited	Enable auditing on assigned_to and assignment_group
Timeline out of order	Time zone mismatch in queries	Use UTC consistently and convert for display

Examples

Example 1: Shift Handoff Summary

Input: "Summarize all activity on INC0067890 for the incoming shift"

Steps: Retrieve incident, fetch all journal entries and state changes, identify last 4 hours of activity, generate condensed handoff summary with current state, pending actions, and risk assessment.

Example 2: Major Incident Executive Report

Input: "Generate an executive summary of the P1 incident INC0067890 for the CTO"

Steps: Retrieve incident and all activity, calculate key metrics (time to detect, respond, resolve), assess business impact, generate executive-level narrative without technical details, include prevention measures.

Example 3: Bulk Activity Summary for Daily Standup

Input: "Summarize all P1 and P2 incidents from the last 24 hours"

Steps: Query incidents opened or updated in the last 24 hours with priority 1 or 2, generate brief (3-5 line) summary for each, include current state and owner, aggregate metrics (total incidents, resolved count, still open count).
