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

AgentHuman
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.

5DecisionSplits on the source check and the confidence gate
Steps trace, template holds

Goes to the owner as a drafted revision.

A step will not trace

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

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 required8 items

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.

Example output

One drafted step, annotated

Everything the agent writes into the draft is attached to the version and the source it came from.

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 document a change reachesFrom your document system
03Drafting & impact

Apply your template and standards

Use the site template, the house drafting rules, the current versions and the sources each step cites.

01Approved path

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.

02Human review

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.

04Build 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.

Integrations

Typical integrations

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

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.

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.

Depth of coverage ▼
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?

Failure modes

Seven failure modes plotted against the five stages of the agent lifecycle.

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.

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 stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Edits and held steps gather in one kind of document.

02Diagnose

QA's edit says more about the cause than the drafting log does.

03Improve

The drafting rule, template check or source map is changed under change control.

04Verify

Affected documents are redrafted and compared against the approved text.

05Learn

What QA wrote instead is what the next draft of that step is measured against.

Learn → DetectThe 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.

Delivery timeline

Four phases across six weeks

Phases are drawn over the weeks they actually occupy. Week 5 connects the document system and puts drafts in front of owners.

Phase W1W2W3W4W5W6
Discovery W1
Build W2 – W3
Evaluate W4 – W5
Pilot & Launch W5 – W6
Week focus W1Template, house drafting rules and the approval boundary agreed W2Document system, change control and current-version retrieval W3Drafting, redlines and hazard-source binding W4Impact-mapping tests, safety-content checks and cohort slices W5Document-system integration, first reviewed revisions and edits W6Production validation, live revisions with QA and Agent Care handover
Reading the bandThe 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 W6A revision has been through your own document control end to end. What Agent Care watches after that is the template and the source map.

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.
