Agent Care

What this agent does

Carries the calendar, never the legal act

In

  1. 01

    Track the executed contract, its amendments and the form version in force, each with the document it came from.

  2. 02

    Track document receipt against the contract checklist, and report what is outstanding rather than clearing it.

Reason

  1. 03

    Compute candidate deadlines from the instrument's own text, with the governing clause quoted beside each date.

  2. 04

    Compute against the form's business-day convention, holiday calendar and cut-off time, never a house default.

  3. 05

    Compute the schedule again on any amendment, since a moved date changes what sits downstream of it.

Decide

  1. 06

    Escalate a date ahead of expiry and again on lapse, because a passed date cannot be un-passed afterwards.

  2. 07

    Escalate inbound mail carrying wire or payment content to a person, with the instructions left out of the summary.

Out

  1. 08

    Retain the instrument, the computed dates, the escalations and the approvals to the state retention schedule.

  2. 09

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

Product statement

The agent computes and escalates; the licensee of record decides, and in attorney states the closing attorney decides.

Example workflow

One contract, execution to close

  1. 1Contract executedExecuted instrument, addenda, amendments and the form version in force
  2. 2Dates computedBase date, day convention, holiday calendar and the clause governing each deadline
  3. 3Schedule proposedCandidate dates, quoted clauses, notice path and confidence
  4. 4Controls appliedVersion checks, day-convention checks, wire-content screening and confidence threshold

No human action required

Stages 1 to 4 run unaided, and nothing is filed or sent at any of them — the agent is computing dates, and the licensee's lane opens at the confidence gate.

5DecisionBranches on the confidence threshold
High confidence

Goes to the licensee of record.

Low confidence

Picks up a broker review first.

Licensee approval

The date is held with its quoted clause, its notice path and the confidence.

Approve · Correct · Refer to attorney

Approved — released to the file

  1. 6Transaction platform updatedOnly where write access and approval policy allow it
  2. 7Outcome evaluatedDate accuracy, escalation timeliness, lapses and licensee corrections

Corrections

Each correction a licensee makes is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required

8 items

  • Waiving, removing or extending a contingency.
    • Drafting an amendment, addendum or extension.
    • Advising on contract meaning or a party's options.
    • Transmitting or confirming wire or payment instructions.

  • Automation boundary

    Agent acts unaided

    • ✓Compute candidate deadlines with the governing clause quoted.
    • ✓Track document receipt against the contract checklist.
    • ✓Escalate approaching and lapsed deadlines to the licensee.
    • ✓Assemble and retain the transaction file to the state retention schedule.

    Writes land inside the boundaries agreed at implementation, and never on a held act.

    • Selecting or recommending a settlement-service vendor.
    • Releasing or directing release of earnest money.
    • Declaring a transaction clear to close.
  • Communicating on the licensee's apparent authority.

Example output

One deadline, annotated

Everything the agent computes is attached to the clause it was read from.

Notice path
Notice-dependent — licensee sends

As received

Taken from the executed contract and its amendments — nothing on this side is written by the agent.

Source clauses used

  • Executed contract
  • Amendment on file
  • Form version in force

Why this date

It counts business days under the form in force — the date the licensee weighs.

What the score decides

Below the configured threshold the date takes a broker review before it reaches the licensee.

Action

ApproveCorrectRefer to attorney

Value

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

Each active contract

From the executed instrument

03Coordination

Compute from the instrument

Draw on the executed text, the form version in force and the escalation rules set by the brokerage.

01Approved path

See the deadline before it passes

Routine date computation and document tracking arrive already done.

02Human review

Send review to the dates that bite

Notice-dependent deadlines and low-confidence dates are marked, so the licensee's read starts where a lapse costs most.

04

Build an evidence trail

Each computed date keeps the clause it came from and the licensee action that followed.

Integrations

Typical integrations

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

  • Transaction management

    • SkySlope
    • Dotloop

  • Forms and e-signature

    • Lone Wolf zipForm
    • DocuSign

  • Back office and compliance

    • brokerWOLF
    • Paperless Pipeline

Agent

Transaction coordination

  • Reads the contract
  • Computes the dates
  • Holds for approval

  • Title and funds verification

    • Qualia Connect
    • CertifID

  • Observability & evaluation

    • OpenTelemetry
    • Langfuse
    • Supported monitoring/evaluation sources

Integration availability depends on the client's existing systems and API access.

Agent controls

Six layers between the model and the deadline

Each control wraps the one inside it. What each layer misses is named in the failure-mode map directly below.

How Nestack evaluates it

Evaluate the coordination workflow — not only the date on the calendar.

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

Surface — the schedule the parties act on

  1. E1Final-output evaluationDid each computed date match the clause it was drawn from?
  2. E2Step-level evaluationDid the agent use the executed version, the right convention and the current form?
  3. E3Tool evaluationDid it read the correct contract and write the correct deadline record?
  4. E4Confidence calibrationDo low-confidence dates actually attract more licensee corrections?
  5. E5Slice evaluationHow does performance change across specific contract types?
  6. E6Business outcomeHow many deadlines lapsed without an escalation the licensee actioned in time?

Floor — the outcome the brokerage answers for

Failure modes

Where each failure originates in the agent

Seven failure modes, each placed at the stage where it starts.

Affected slices

The all-contract rate hides the cohort

A missed-deadline rate that reads acceptably across all contracts sits on cohorts that miss at several times that rate, and on cohorts well under it. Nestack reports the rate by slice, not only in total.

Slice performance — reported separately, not only in aggregate

2 of 4 slices over threshold

Evidence-linked improvement

A cycle ends in a test, not a fix

A passed date cannot be un-passed, and renegotiating it is the counterparty's choice — so the cycle closes only once the miss is a regression case.

Improvement cycle · five stages

Switchback — the path turns at Improve and returns at Learn

  1. 01

    Detect

    Missed-deadline rate rises in a contract cohort.

  2. 02

    Diagnose

    The base date is checked first, then the form version and the day convention, until the cause narrows to one.

  3. 03

    Improve

    The correction is version-stamped, and dates computed off the old rule are recomputed.

  4. 04

    Verify

    Release waits on the affected regression cases passing again.

  5. 05

    Learn

    The case becomes a standing test and a line in the escalation rules.

  6. Learn → Detect

    The return edge. What catches the next miss is longer by this case.
