Knowledge-Base Maintenance AI Agent

Retire the article a release overtook, surface the questions the corpus never answers and mark what no one owns, then hold each revision for the documentation owner who decides what is published.

What this agent does

Proposes the revision, never publishes it

In
01

An article is written, and the release it describes is recorded beside it as the version it was true of.

02

A release ships, and each article describing what it changed is proposed for revision rather than left.

Reason
03

A question arrives that no article answers, and the gap is logged against the corpus, not the customer.

04

An article loses its owner to a reorganisation, and it is marked unowned rather than assumed maintained.

05

A source article is corrected, and each translation still carrying the older wording is flagged as forked.

Decide
06

A product is retired, and the articles still describing it are listed while they go on being found.

07

An article answers through the deflection agent, and any staleness in it is repeated in a confident voice.

Out
08

An article resists an owner, and that absence is reported as the finding rather than left as a blank field.

09

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

Product statement

Detection, drafting and coverage mapping belong to the agent. Publication belongs to a named documentation owner, who republishes the article and owns what it says.

Example workflow

One article, release to republication

AgentHuman
1Change record receivedRelease notes, change logs, ticket themes, search queries or the article corpus itself
2Article set matchedThe articles describing what changed, the owner on record and the day each was last verified
3Revision proposedThe passage overtaken, the suggested wording, the coverage gap and confidence
4Controls appliedOwner checks, freshness checks, duplicate-answer checks and confidence thresholds
No human action required

Stages 1 to 4 run unaided, and nothing reaches the help centre at any of them — the agent is proposing, and the owner lane opens at the confidence gate.

5DecisionSplits at the confidence threshold
High confidence

Goes to the named owner to publish.

Low confidence

Adds a senior writer read first.

Owner review

The revision is held with the release behind it, the passage it replaces and the confidence.

Approve · Amend · Send to writer review
Published — by the named owner
6Documentation platform updatedOnly where write access and publication policy allow it
7Outcome evaluatedFreshness after release, coverage gaps closed, owner amendments and what review found
Amendments

Each documentation-owner amendment is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required8 items
Publishing an article to the help centre.
Retiring an article or taking it off the shelf.
Deciding which of two answers is the correct one.
Approving a translated article for a locale.
Automation boundaryAgent acts unaided
Match each release to the articles it overtakes.
Record the day an article was last verified against a release.
Read the questions customers asked and mark the ones no article answers.
Mark an article unowned when the owner named on it has left.
Nothing reaches the help centre except by a named owner, inside the agreed boundaries.
Judging whether a gap is worth an article at all.
Telling a customer that an article is current.
Naming the owner an unowned article passes to.
Changes to the authoring, freshness or owner rules.

Example output

One article revision, annotated

This serves a documentation team asked long afterwards why an article still said what it said; below is one revision 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 articleFrom the release that changed it
03Evidence

Where the evidence is used

The agent does not decide what is correct, only which release touched which article, when it was last verified, and which questions the corpus leaves unanswered.

01Approved path

The answer went stale quietly

Nothing announced it. The article was right the morning it was written, a release shipped in March, and the ranking never moved.

02Human review

What was checked, and not found

Nothing in the corpus records which questions have an answer, only how many articles sit on the shelf, so coverage is read from the questions customers actually asked through to the articles that answered them.

04Build an evidence trail

The article, the release that changed it and the owner who republished 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 maintenance loop — not only the revision that comes out.

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

Surface — the answer a customer reads
Depth of coverage ▼
E1Final-output evaluationDid the revision cite the release that actually overtook the article?
E2Step-level evaluationDid the agent read the right article, the right release and the live owner record?

Affected slices

Recent releases carry the amendments

A product-level freshness figure can read clean while the articles behind one recent release carry most of the amendments. Nestack reports the amendment rate by product area, not only in total.

Evidence-linked improvement

What a quiet release costs

A loop closes when the article overtaken by a release is a standing case. That suite is what the next revision published is measured against.

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

Amendment rate rises on recently released features.

02Diagnose

The help article that was right on the morning it was written and has been wrong since March is worked backwards until one cause is left standing.

03Improve

Number the change; the articles that drove it are filed beneath it.

04Verify

A single red article case stops the whole release.

05Learn

One case joins the suite, one line joins the authoring rules.

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

Typical build scope

Next step · Support AI agent

Build a knowledge-base agent around the release your last article never noticed.

Show us one product area and the articles that describe it. If nobody in your library owns an article and nobody has verified it against a release, then it is being trusted rather than maintained. A question the corpus cannot answer comes back as a finding.
