Support Copilot AI Agent

Hand a draft to the person answering, surface only the part of the record the reason for contact justifies, and leave the sending to a named queue lead who edits what goes out.

What this agent does

Drafts the reply, never sends it

In
01

A draft is offered to the person answering, and this agent never speaks to the customer at all.

02

A reply is sent by that person, and Art. 50(1) binds the provider of a system, not you.

Reason
03

A draft reviewed and sent by a human as the main interlocutor is excepted by the Guidelines.

04

A reply whose review is a mere possibility circumvents the duty, which that paragraph refuses.

05

A draft whose object is the customer problem sits outside the four verbs of Annex III 4(b).

Decide
06

A draft scored per person, or a ticket routed by behaviour at the desk, moves it inside.

07

A draft tool that also scores is not classified by halves, says guidance that is still draft.

Out
08

A draft tuned to mood is prohibited for the person answering, high-risk for the customer.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

Drafting, scoping the record to the reason for contact and logging every read belong to the agent. Sending belongs to a named queue lead, who edits the draft and owns what goes out.

Example workflow

One reply, drafted to sent

AgentHuman
1Ticket arrives at the queueEmail, chat, web form, an in-app session or a thread routed in from another queue
2Record scoped to the reasonThe reason for contact, the fields it justifies and every read logged against the ticket
3Reply drafted for a personThe draft, what each claim rests on, the flagged lines and confidence
4Controls appliedRecord-scope checks, source checks on each claim, inference checks and confidence threshold
No human action required

Stages 1 to 4 run unaided, and nothing reaches the customer at any of them — the agent is drafting, and the lead lane opens at the confidence gate.

5DecisionBranches at the confidence threshold
High confidence

Goes to the named queue lead to send.

Low confidence

Adds a second reviewer read first.

Queue lead review

The draft is held with the record it drew on, its flagged lines and the confidence.

Approve · Edit the draft · Send to reviewer
Sent — by the named queue lead
6Conversation record updatedOnly where write access and records policy allow it
7Outcome evaluatedDraft survival by intent, edit outcomes, review depth and what review found
Edits

Each lead edit is counted in the evaluation.

Example output

One drafted reply, annotated

This serves a desk where staff who over-read a customer record have been prosecuted as individuals while their employer was not; below is one draft exactly as the agent leaves it.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every reply that leavesFrom the ticket in front of you
03Drafting

Draft it, then hand it over

The customer-success ticket-deflection agent answers the customer directly; this one never speaks to the customer, and the person at the desk is its user rather than its subject.

01Approved path

Review is not a rubber stamp

The exception is not a checkbox but a claim about what the person did, and an approval faster than the subject line can be read is not a review.

02Human review

What was checked, and not found

No US law requires telling a customer that a human reply was AI-drafted: the California bot statute misses on the bot, the forum and the intent, Utah needs an interaction that never happens, Colorado repealed its act.

04Build an evidence trail

The draft, the agent who edited it and the reply that actually went stay together.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

How Nestack evaluates it

Evaluate the whole drafting run — not only the reply that goes out.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Failure modes

Where each failure originates in the agent

Seven failure modes, each placed where the draft first goes wrong.

Affected slices

Refund requests absorb most of the editing

An intent-level review-depth figure can read clean while refund and goodwill requests carry most of the editing. Nestack reports the edit rate by intent, not only across a whole desk in total.

Evidence-linked improvement

What an unread draft costs

A cycle ends when the draft that went out unread is a standing case. That suite is what the next reply sent is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Approvals speed up on one ticket intent.

02Diagnose

The draft that was approved in the time it takes to read a subject line is worked backwards until one cause is left standing.

03Improve

The change ships numbered, and the drafts that forced it ride with it.

04Verify

One draft case still failing is enough to hold the release back.

05Learn

It is kept for good, and the drafting rules are amended in the same commit.

Learn → DetectThe return edge. The next draft is measured against a suite one case longer.

Typical build scope

Twelve workstreams across six weeks

The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, drafting workflow, evaluation, integration, then production validation and handover.

Next step · Customer Support AI agent

Build a support copilot around the review your desk cannot now show it actually did.

Show us one queue and the replies it sent last week. The person who reviews the draft and sends it is the interlocutor, and the exception rests on that being true rather than on a button existing. Bring one reply approved faster than it could be read.
