Biotechnology AI agent · Lab methods
Lab-Protocol Assistant (Method Drafting)
Draft and revise the methods people run at the bench — to your own template, with hazards, version history and the documents each change touches — for a document owner and QA to approve.

What this agent does
Drafts the method, does not issue it
In
- 01
Take the change — a reagent, an instrument, a revised standard — and the documents it is said to touch.
- 02
Read the approved versions, their revision history and the site template they have to be written into.
Reason
- 03
Draft the method into that template: scope, materials, steps, hazards, containment, waste route and records.
- 04
Work out which other documents the change reaches — linked methods, forms, equipment records and training.
- 05
Compare each step against the source it cites, and mark cross-references that no longer resolve.
Decide
- 06
Hold any draft whose hazard, containment or waste step cannot be traced to the safety source it names.
- 07
Route the redline, the impact list and the open questions to the document owner and QA who own them.
Out
- 08
Present the draft with the effective-date and training fields left empty for the people who set them.
- 09
Keep each version with the reason it changed, and the reviewer edits made against the draft.
Product statement
The agent drafts, compares and routes inside the approval boundaries agreed during implementation. Approval, issue, the effective date and the training requirement stay with the document owner, QA and the lab head.
Example workflow
One method revision, end to end
- 1Change receivedA reagent, instrument, standard or specification change, and the documents it is said to touch
- 2Current versions gatheredThe approved method, its revision history, the site template and the standards it is written against
- 3Impact worked outWhich methods, forms, equipment records and training assignments the change reaches, and what has gone stale
- 4Draft written and checkedSteps, hazards, containment and waste written into the template, each bound to the source it cites
No human action required
Stages 1 to 4 run without a person in the loop — the document owner is not asked to read anything until the impact list and the source checks are done. A hazard step that will not trace stops the draft where it stands.
Goes to the owner as a drafted revision.
Held with the untraceable steps marked.
Document owner, QA and lab head
Read the redline against the impact list, the flagged steps and what could not be traced to a source.
Approve · Edit · Send back
Approved — handed back
- 6Pack assembled and filedWritten to the document system as a draft only where access and policy allow; the effective date stays empty
- 7Outcome evaluatedSource-check failures, documents missed from the impact list, reviewer edits and what QA sent back
Edits
Steps the reviewer rewrites or removes are counted in the evaluation.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Approving or issuing a controlled document.
- Setting an effective date or releasing a method.
- Changing a specification or an acceptance criterion.
- Signing or assigning a training record.
Automation boundary
Agent acts unaided
- ✓Draft and redline methods into your own template.
- ✓Bind each step, limit and hazard to the source it cites.
- ✓List the documents, forms and training records a change reaches.
- ✓Hold untraceable steps and route the pack to the owner and QA.
Write actions run only inside the approval boundaries agreed during implementation. An effective date is not one of them.
- Authorising work with a hazardous or biological agent.
- Withdrawing or superseding a method in use.
- Deciding that a change touches nothing else.
- Changing the template, drafting rules or thresholds.
Example output
One drafted step, annotated
Everything the agent writes into the draft is attached to the version and the source it came from.

As received
The change as it was raised, beside the approved version it lands in — nothing on this side is drafted.
Evidence used
- Approved version read
- Supplier safety data sheet
- Template and house rules
Why the hazard line moved
The new safety data sheet carries a different hazard statement for that step.
What the score decides
Below the configured threshold the step is held for the owner instead of entering the draft pack.

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 document a change reaches
From your document system
Apply your template and standards
Use the site template, the house drafting rules, the current versions and the sources each step cites.
Start review from a real draft
The redline, the impact list and the sources arrive together, so a document owner opens something they can check rather than an empty template.
Put QA on the steps that will not trace
Steps with no traceable source, cross-references that no longer resolve and stale linked documents are marked for a named reviewer.
Build an evidence trail
Retain the change as raised, the versions read, each drafted step with its source, the impact list, the confidence and every reviewer edit — on both paths.

Agent controls
Six layers between the model and the method
Each control wraps the one inside it. A drafted step clears every layer before it reaches the pack an owner reads.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Decide whether a step may stand
- L3
- Keeps limits where QA set them
- L4 – L5
- Leave issue to a person, keep the trail
- L6
- Pulls automation back when signals degrade
How Nestack evaluates it
Evaluate the whole revision — not only the draft at the end.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the draft pack the owner opens
- E1Final-draft evaluationDid the drafted step match the source, and say no more than it?
- E2Source-check evaluationDoes each cited document exist, carry the limit and still stand?
- E3Impact-list evaluationWhich affected documents were missed against the reviewer's own list?
- E4Safety-content evaluationAre hazard, containment and waste steps carried from the safety source?
- E5Slice evaluationHow does draft quality change across specific document cohorts?
- E6Business outcomeHow much of the pack was rewritten or sent back by QA?

Failure modes
Where each failure originates in the agent
Seven failure modes plotted against the five stages of the agent lifecycle.

01 · Intake / retrieval
1 mode
- LP-01
Drafted from a superseded version
The change lands in a revision that is no longer current.

02 · Impact
2 modes
- LP-02

Hazard or waste step not carried
The safety source changed; the draft keeps the old wording.
- LP-05
Template sentence left in the method
A generic step survives and describes nothing anyone does.
Stage drafts
Steps, hazards and limits, each bound to a source
04 · Pack / output

- LP-06
Draft worked from as if effective
An unapproved redline is printed and used at the bench.

05 · Change / Version
1 mode
- LP-07
Silent drafting-rule regression
A template or rule change moves drafts with no record.
Stage tracks
Template, model, prompt and drafting-rule changes
- Sev-1 · an uncontrolled step could reach the bench
- Sev-2 · the pack misstates what changes
- Sev-3 · drafting degrades, more goes back
Affected slices
Some documents cost far more edits than others
A step counts here when its source check fails, or when the document owner rewrites it before QA ever sees it. Methods typed in the paper era carry cross-references that stopped resolving years ago.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Legacy paper-era methods | 5.4% | 2.7× | Review | |
| Methods transferred between sites | 4.2% | 2.1× | Review | |
| Multi-document change requests | 3.3% | 1.7× | Watch | |
| Routine periodic-review revisions | 1.4% | 0.7× | Normal |

Evidence-linked improvement
An edit by QA does not stop at the draft it was made in
Nothing here closes on one revision. What a reviewer wrote instead becomes a check the drafting runs before the next redline is written.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Edits and held steps gather in one kind of document.
- 02
Diagnose
QA's edit says more about the cause than the drafting log does.
- 03
Improve
The drafting rule, template check or source map is changed under change control.
- 04
Verify
Affected documents are redrafted and compared against the approved text.
- 05
Learn
What QA wrote instead is what the next draft of that step is measured against.
Learn → Detect
The return edge. A change to the template or the drafting rules is itself a change — named approver, impact assessment and a record, before the next draft is written.
Typical build scope
Twelve workstreams across six weeks
The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, versions and impact, drafting and safety binding, evaluation, integration, then production validation and handover.

W6Production validation, live revisions with QA and Agent Care handover
- Reading the band
- The bars are drawn over the weeks the work is actually named in. Week 3 is the first week a draft exists; without the template and the boundary a redline means nothing.
- At the end of W6
- A revision has been through your own document control end to end. What Agent Care watches after that is the template and the source map.
- Duration
- Six-week plan shown · typical delivery 4–6 weeks depending on scope confirmed in discovery.
Next step · Biotechnology AI agent
Build a protocol assistant around the document control you already run.
Show us one method, the change that last forced it open, and the pack your document owner and QA sign. Drafting is the easy half. The hard half is knowing which linked forms, equipment records and training assignments that one change has quietly aged.
