What this agent does
Drafts the answer, never states the entitlement
In
- 01
A question about holiday or notice arrives, and the clause it is answered from is named beside it.
- 02
Varity, 516 U.S. 489, 1996: answering a benefits question is itself a fiduciary act.
Reason
- 03
Amara, 563 U.S. 421, 16 May 2011: a summary describes a plan and is not its terms.
- 04
Eddy, D.C. Cir., 23 November 1990: complete and correct material information, not merely true.
- 05
29 CFR 2520.102-2(b): a limitation may not be minimised, so the carve-out rides with the benefit.
Decide
- 06
29 CFR 790.13: the good-faith defence needs a written instrument this agent cannot issue.
- 07
A commencement instrument moves a qualifying period, and the stored answers are re-derived.
Out
- 08
An entitlement turns on a fact no policy holds, and that dependency is recorded as the finding.
- 09
Execute write actions only inside the approval boundaries agreed during implementation.
Product statement
Drafting, sourcing and holding belong to the agent. Release belongs to a named adviser, who states the entitlement and owns what the employer has said.
Example workflow
One entitlement question, corpus to release
- 1Question receivedHandbook clauses, plan documents, summaries, the contract file and the applicable particulars
- 2Documents identified and rankedWhich instrument governs, which is a summary of it, and the day each version took effect
- 3Draft answer builtThe entitlement stated, the clause cited, the carve-out attached and what the corpus could not reach
- 4Controls appliedJurisdiction checks, commencement checks, summary-against-plan checks and release confidence
No human action required
Stages 1 to 4 run unaided, and nothing is said to an employee at any of them — the agent is drafting, and the adviser lane opens at the confidence gate.
Goes to the named adviser to release.
Adds a benefits-counsel read first.
Adviser review
The draft is held with the clauses under it, the carve-outs and the confidence.
Release · Attach clause · Send to counsel
Released — by the named adviser
- 6Case and answer records updatedOnly where write access and records policy allow it
- 7Outcome evaluatedClause accuracy, carve-out coverage, adviser corrections and what review found
Corrections
Each adviser correction is counted in the evaluation.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Telling an employee what they are owed.
- Deciding which document governs the entitlement.
- Refusing a request that is in substance a claim.
- Signing a written statement of particulars.
Automation boundary
Agent acts unaided
- ✓Cite the clause that supports each drafted answer.
- ✓Set the disqualification clause beside the benefit that it limits.
- ✓Check each quoted period against the commencement instrument in force.
- ✓Hold the draft where the jurisdiction is unstated.
Nothing reaches an employee except by a named adviser, inside the agreed boundaries.
- Judging whether a policy is a term of the contract.
- Assuring anyone that a benefit will be paid.
- Ranking a summary above the plan it describes.
- Changes to the handbook, the plan or the particulars.
Example output
One entitlement answer, annotated
This serves an HR team who may have to explain, years later, why a worker was told what they were told; below is one drafted answer exactly as the agent leaves it.
Entitlement answer · single question
Illustrative example- Question
- Paternity leave in the first year
- Answer
- No qualifying period applies to a GB worker on these facts
- Status
- Draft, unreleased
- Instrument cited
- ERA 2025 s.16, 6 April 2026
- Confidence
- Summary, not plan terms
- Held for
- The named adviser, by name
As received
Drawn from the commencement instrument and the handbook clause, and it claims nothing beyond either.
What the record holds
- Handbook clause
- Commencement date
- Contract particulars
Why no release here
Saying what a worker is owed is a judgement a named adviser makes.
What the score decides
Below the configured threshold an answer gets a counsel read before the adviser sees it.

ReleaseAttach clauseSend to counselValue
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 answer
From the clause that carries it
Where the answer is used
The agent vouches for what a policy says and the day it took effect, not for the outcome. Pearce, 6th Cir., 20 June 2018: unambiguous plan terms defeated estoppel — capable of binding is not bound.
Saying it can make it so
On remand the Second Circuit affirmed reformation of the plan to adhere to representations made by the plan administrator, 23 December 2014.
What was checked, and not found
No regime checked requires an employer to keep a record of the advice it gave a worker about an entitlement. But 29 CFR 825.500(c)(4) retains the written notices given to employees, and (c)(5) the documents describing policies and practices, which at scale is the same file.
Build an evidence trail
The answer, the document it came from and the adviser who released it stay together.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.
Policy and handbook stores
- SharePoint
- policy libraries
- Handbook clauses and their dates
Benefits administration
- Plan documents
- summaries
- Eligibility and its carve-outs
Core HR records
- Workday
- SAP SuccessFactors
- Hire dates, the entity and jurisdiction
Agent
Policy and entitlement answering
- Reads the clauses
- Drafts the answer
- Holds for the adviser
Contract and statutory files
- Offer letters
- s.1 particulars
- Notice, holiday and sick-pay terms
Observability & evaluation
- OpenTelemetry
- Langfuse
- Supported monitoring/evaluation sources
Integration availability depends on the client's existing systems and API access.
Agent controls
Six gates between the corpus and the employee
Six gates down one corridor, the last the narrowest. What clears is set out in the map below.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether an answer may be released
- L3
- Leaves the statement to a named adviser
- L4 – L5
- Keep the answer and the document behind it
- L6
- Answers with the document alone when signals degrade
How Nestack evaluates it
Evaluate the whole draft — not only the answer that comes out.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the answer a worker reads
- E1Final-output evaluationDid the answer record the clause it was actually drafted from?
- E2Step-level evaluationDid the agent read the right document, the right version and the right entity?
- E3Tool evaluationDid it read and write the correct worker and the correct entitlement?
- E4Confidence calibrationDo low-confidence answers actually attract more adviser corrections?
- E5Slice evaluationHow does performance change across specific entitlement classes?
- E6Business outcomeHow many answers needed a correction before the adviser released?
Floor — the corpus an answer rests on
Failure modes
Where each failure originates in the agent
Seven failure modes, each at the stage where it first becomes visible.
Agent lifecycle
Direction of processing →
01 · Retrieval
1 mode
- TI-03
Wrong-entity document read
The policy pulled belongs to another entity or another jurisdiction.
Stage gathers
The clauses, the plan text, the dates and the entity
02 · Reasoning
2 modes
- TI-04
Summary answered as plan
A benefit is stated from a document that is not the plan.
- TI-06
Withdrawn letter cited as live
A rescinded interpretation is worked as current authority.
Stage proposes
The entitlement, the clause, the carve-out and confidence
03 · Tool / write
2 modes
- TI-02
Carve-out left off the answer
The benefit is stated and the condition on it is not.
- TI-05
Answer worded as a refusal
A no becomes a determination nobody wrote up.
Stage writes
Only where write access and approval policy allow it
04 · Output
1 mode
- TI-01
The answer becomes the term
A released statement is read later as what the employer promised.
Stage returns
The answer an employee acts on and a court reads
05 · Change / Version
1 mode
- TI-07
Silent commencement drift
A qualifying period is removed and the stored answers keep it.
Stage tracks
Model, prompt, clause rules and in-force dates
- Sev-1 · an entitlement promised in error
- Sev-2 · a superseded rule reaches a worker
- Sev-3 · source degrades, answer held back
Affected slices
Cross-border questions absorb the corrections
A department-level accuracy figure can read clean while cross-border entitlements carry most of the adviser corrections. Nestack reports the correction rate by answer class, not only in total.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Cross-border entitlements | 13.7% | 3.7× | Review | |
| Plan-governed benefits | 9.7% | 2.6× | Review | |
| Recently commenced rights | 6.1% | 1.6× | Watch | |
| Settled handbook questions | 2.8% | 0.8× | Normal |
Bar: correction-rate lift vs. the settled-handbook baseline · scale 0–4.0× · tick marks the 2.0× review threshold
2 of 4 slices over threshold
Evidence-linked improvement
What a promised benefit costs
The loop shuts when the assurance no plan document carries is a standing case. That suite is what the next answer released is measured against.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Correction rate rises on cross-border entitlements.
- 02
Diagnose
The benefit that existed only because somebody said it did is worked backwards until one cause is left standing.
- 03
Improve
Every answer goes out numbered, with the clauses that support it attached.
- 04
Verify
Nothing releases while one touched entitlement case is red.
- 05
Learn
The case stays on, and the answering rules are rewritten alongside it.
Learn → Detect
The return edge. The next answer is measured against a suite one case longer.
Typical build scope
Twelve workstreams across six weeks
The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, answer drafting, evaluation, integration, then production validation and handover.

Next step · HR AI agent
Build an entitlements copilot around the document your last answer never named.
Show us one entitlement your team answers week after week and the clause behind the last answer. If it went out without naming the document it came from, what the employer said is now the only record of what the employer meant. A benefit no plan carries comes back as a finding.
