Duplicate Ticket and Repeat Failure Linker

Catches duplicate tickets and links related ones so a recurring problem reads as one thread instead of five disconnected work orders, and flags the repeat failures that need a root-cause fix rather than another patch.

The Problem

The same problem lives in five disconnected tickets.

Same issue, multiple tickets, nobody connecting them. Root causes stay hidden.

What Changes

One linked thread. Repeats flagged for a real fix.

Detects duplicate tickets, links related ones, and flags when the same problem keeps recurring at the same unit. Your team sees patterns, not just individual tickets.

Humans stay in control: Your coordinator decides what to merge and when to escalate a repeat. The agent finds the connections and surfaces the pattern. It removes the fragmented history, not the judgment.

The agent doesn't decide what to merge or escalate. Your coordinator does. The agent finds the connections and the pattern.

HOW TO BUILD IT

Three levels of depth. Pick the one that matches where you are.

The AgentWorkflow engine + LLM

Your HistoryLinked threads, repeats

WHAT YOUR TEAM PROVIDES ONCE

Ticket history access - so the agent can search past work orders
Match rules - what makes two tickets duplicate vs related
Repeat-failure definition - how many times in what window counts
Merge policy - what to do with a confirmed duplicate
Escalation path - who owns a flagged recurring failure

What happens day-to-day: A new ticket comes in. The agent checks whether it’s the same issue someone already reported, links it to the related history, and if the same thing keeps breaking, flags it for a root-cause fix instead of a fifth patch. Your team stops solving the same problem over and over.

WITHOUT PMS API

Agent matches against an exported ticket export and outputs proposed links for manual application. The matching logic still runs.

WITH PMS API

Agent searches live ticket history and writes links and repeat flags directly. Best experience.

For the person who wants to build this agent step by step. Each node below maps to an n8n workflow node.

TRIGGERNode 1

Trigger - New Ticket

Webhook on new work order, or chain from an intake agent.

Output: { ticket_id, unit_id, asset, description, created_at }

APINode 2

HTTP Request - Search History

Pull recent tickets for the same unit and asset within your lookback window.

Output: [{ ticket_id, description, date, status, resolution }]

LLMNode 3

LLM - Match Tickets

Compare the new ticket to history and classify each as duplicate, related, or unrelated.

Output: { duplicates[], related[], reason }

You find duplicate and related maintenance tickets.

Compare the NEW TICKET to the HISTORY. Using MATCH RULES, return:
- duplicates: ticket_ids that are the same active issue
- related: ticket_ids about the same asset/problem area but not duplicates
- reason: one line explaining the strongest match

Respond ONLY with valid JSON.

MATCH RULES: {match_rules}
NEW TICKET: {new_ticket}
HISTORY: {history}

INPUT

new: 'AC not cooling, unit B-214'; history has 'B-214 AC weak cooling' 8 days ago, still open

OUTPUT

{
  "duplicates": ["WO-2199"],
  "related": ["WO-2040"],
  "reason": "Same unit AC cooling complaint, prior ticket still open = duplicate."
}

DECISIONNode 4

Condition - Match Found?

IF duplicates → merge per policy. IF related only → link. IF none → leave standalone and continue to repeat check.

Output: Branch: DUPLICATE (merge) / RELATED (link) / NONE

APINode 5

HTTP Request - Link or Merge

Apply the merge policy for duplicates or attach links for related tickets in the PMS.

Output: Tickets linked or merged; history now reads as one thread.

LLMNode 6

LLM - Detect Repeat Failure

Check whether this asset has failed repeatedly within the window, signalling a root-cause issue.

Output: { repeat: true|false, count, window, summary }

You detect repeat failures for an asset.

Given the linked ticket history and the REPEAT DEFINITION, return:
- repeat: true if the same failure recurs beyond the threshold
- count: how many times in the window
- window: the time span
- summary: one line for a manager

Respond ONLY with valid JSON.

REPEAT DEFINITION: {repeat_definition}
ASSET HISTORY: {asset_history}

OUTPUT

{
  "repeat": true,
  "count": 3,
  "window": "90 days",
  "summary": "B-214 AC has failed 3 times in 90 days - recommend compressor/root-cause review, not another recharge."
}

ACTIONNode 7

Flag Root Cause

For repeat failures, escalate to the maintenance supervisor with the pattern so the fix targets the cause.

Output: Recurring failure surfaced for a root-cause decision.
