What this agent does
Drafts the paperwork, never authorises it
In
- 01
Take the equipment record, energy sources, isolation points and drawings for one machine from your asset data.
- 02
Load the procedures, analyses, permits and safety data sheets on file, and the change log that says what moved.
Reason
- 03
Draft a machine-specific procedure — each energy source, its isolation point, the verification step and the order.
- 04
Re-read the analyses, permits and records that name the machine, the task or the chemical that changed.
- 05
Check each safety data sheet against the supplier's current issue and the chemical inventory the plant holds.
Decide
- 06
Flag a document where the drawing, the walk-down note and the energy-source list do not agree with each other.
- 07
Hold anything drafted from a general template rather than that machine's own data, and say which it was.
Out
- 08
Assemble the pack — draft, sources read, what changed, open questions and the documents naming that machine.
- 09
Present it for verification. Nothing is live until a safety professional has walked it down and authorised it.
Product statement
The agent drafts, cross-references and flags. A competent safety professional verifies the document against the machine as it stands today and authorises it — no document is live until they do.
Example workflow
One change, end to end
- 1Change loggedA machine rebuild, a new guard, a modified task, a chemical substitution or a safety data sheet reissued by the supplier
- 2Affected documents foundThe procedures, analyses, permit templates, inspection records and training records that name that machine, task or chemical
- 3Machine data readEquipment record, energy sources, isolation points, drawings, prior walk-down notes and the date the document was last verified
- 4Draft preparedThe revised procedure or analysis, with every energy source, isolation point and verification step traced to where it came from
No human action required
Stages 1 to 4 run without a person in the loop — finding, reading and drafting all happen against records. A machine with no current walk-down ends that stretch on the spot.
Reaches the safety professional to verify.
Stops with the gap named and drafts no further.
Safety professional
Walks the machine down against the draft, corrects what the record got wrong, then authorises and issues it.
Verify on the machine · Correct · Send back
Authorised — handed back
- 6Pack filed for verificationDraft, sources, diff, open questions and the walk-down checklist — written to the document system as unapproved
- 7Outcome evaluatedWhat the walk-down corrected, what the reviewer rewrote, and which documents were still stale at the next audit
Corrections
What the walk-down changes is counted in the evaluation.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Authorising or issuing a permit to work.
- Certifying a lockout procedure as verified.
- Signing off a job hazard analysis or risk assessment.
- Closing an incident, investigation or corrective action.
Automation boundary
Agent acts unaided
- ✓Draft machine-specific procedures from equipment and energy-source data.
- ✓Search the documents you hold for what names that machine, task or chemical.
- ✓Compare safety data sheets against supplier issue dates and the inventory.
- ✓Assemble the pack, flag stale documents and name what it could not verify.
The agent writes drafts and flags into the document system, always unapproved. Authorising them is not its to write.
- Deciding a machine may be worked on.
- Declaring a document current without a walk-down.
- Changing an isolation point or an energy-control method.
- Approving a chemical substitution or a new chemical.
Example output
One procedure revision, annotated
Everything the agent drafts is attached to the change that triggered it and the machine record it was read from.
Draft output · single procedure revision
Illustrative example- Change logged
- Guard and clamp rebuild
- Machine
- Trim press 4, rebuilt
- Document
- Lockout procedure, rev 6
- Drafted
- Energy sources, one added
- Confidence
- 86%
- Status
- Unverified — not live
As received
The change as logged and the machine it names, with the revision of the document it affects.
Evidence used
- Energy-source list, press 4
- Rebuild drawings
- Last walk-down note
Why this is flagged
The rebuild added an accumulator that the energy-source list does not carry.
What the score decides
Confidence decides how hard the walk-down looks, never that a document is live.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value lands
Value 01 – 04
Every logged change
Rebuild, new chemical, modified task or a reissued sheet
Work from that machine's own data
Use the equipment record, the energy-source list, the drawings and the walk-down notes for that machine, not a general template.
List the documents a change touches
One rebuild usually lands in a procedure, an analysis, a permit template and a training record. The list arrives for the safety officer to confirm, not one search at a time.
Send the safety lead to the machine
Time goes to the walk-down and the signature instead of to working out which documents named the machine in the first place.
Build an evidence trail
Retain the change that triggered it, the sources read, the draft, the flag, the walk-down result and the authorising signature — on both paths.

Agent controls
Six layers between the model and a live procedure
Each control wraps the one inside it. A draft clears every layer before a safety professional reads it, and the walk-down sits outside all six.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Keep the draft tied to that machine
- L3
- Decides how hard the walk-down looks
- L4 – L5
- Keep authorisation with a person, trail intact
- L6
- Pulls automation back when signals degrade
How Nestack evaluates it
Evaluate the whole document set — not only the procedure at the end.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the draft the safety lead opens
- E1Final-output evaluationWas every hazardous energy source on the machine named, against a walk-down?
- E2Step-level evaluationDid it read the right machine record, drawing revision and walk-down note?
- E3Isolation-point accuracyWas each isolation point the one that actually isolates that source?
- E4Staleness detectionAfter a logged change, was every affected document found and flagged?
- E5Slice evaluationHow does draft quality change across equipment types and ages?
- E6Business outcomeWhat did the walk-down correct, and what was still stale at audit?

Failure modes
Where each failure originates in the agent
Seven failure modes plotted against the five stages of the agent lifecycle. A wrong lockout procedure can get someone killed, so none of these becomes a live document by itself — verification against the actual machine, by a competent person who then signs it, is the control that stops them. If one gets through anyway, the machine is stood down, the document is withdrawn, everyone trained to it is re-briefed, and the record shows what was issued and who authorised it.
Agent lifecycle
Direction of processing →
01 · Retrieval
2 modes
- SD-01
Stored energy missed
Residual pressure, a spring, a raised ram or a charged capacitor.
- SD-02
Isolation point wrong
The disconnect named no longer isolates that source.
Stage reads
The equipment record, energy list, drawings and notes
02 · Reasoning
2 modes
- SD-03
Template, not machine
A general procedure drafted as though it were specific.
- SD-04
Simultaneous work missed
A permit pack that lets two conflicting jobs run at once.
Stage drafts
The procedure, the analysis and the assumptions made
03 · Cross-reference
1 mode
- SD-05
Change does not propagate
The procedure is revised; the analysis and permit are not.
Stage links
Every other document that names the same machine
04 · Output
1 mode
- SD-06
Current but never verified
In date, correctly formatted, never checked against the machine.
Stage returns
The draft and the flags the safety lead reads
05 · Currency / Version
1 mode
- SD-07
Superseded sheet kept
The supplier reissued and the old sheet stays on file.
Stage tracks
Sheet issue dates, template and content versions
- Sev-1 · a person could be hurt by the document
- Sev-2 · the draft rests on the wrong machine
- Sev-3 · records go stale, rework rises
Affected slices
A document is only as good as the machine record behind it
Two machines in one plant are not the same drafting problem. A machine with as-built drawings and a current energy-source list drafts cleanly; a press rebuilt twice, with drawings nobody updated, does not. Reported by slice, not in total.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Rebuilt or modified machines | 6.5% | 3.8× | Review | |
| Legacy machines, poor drawings | 4.8% | 2.8× | Review | |
| Reissued supplier sheets | 3.3% | 1.9× | Watch | |
| Current standard-build machines | 1.3% | 0.8× | Normal |
Bar: walk-down correction-rate lift vs. plant baseline · scale 0–4.0× · tick marks 2.0×
2 of 4 slices over threshold
Evidence-linked improvement
A missed energy source becomes a check on the next draft
What a walk-down corrected, and what an audit found stale, come back as machines the agent is re-tested on before the next pack is drafted.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Walk-down corrections and stale-document findings cluster on one class of machine.
- 02
Diagnose
Traced to the equipment record, a drawing never updated, a missed reference, or a change nobody logged.
- 03
Improve
The retrieval rule, the drafting constraint or the document-link map changes under your document control, with a named approver.
- 04
Verify
Re-run against held-out machines of that type, including the ones the walk-down corrected.
- 05
Learn
That machine becomes a permanent case, and the reason it failed enters the checklist your verifiers work to.
Learn → Detect
The return edge. A change to a safety document is a controlled change — verified, authorised and re-issued before anyone works to it, not after.
