# Deel — Four-stage payroll sync triage pipeline
Deel runs a four-stage pipeline that triages failed US PEO payroll syncs without an engineer starting it. The pipeline detects and batches failures, retries them, investigates the rest with parallel data fetches, classifies the cause and writes the fix command, then posts a per-failure summary to Slack. Deel deployed it on Akai, which the post calls the company's internal AI orchestration platform.

## Purpose
### Summary
Deel runs a four-stage pipeline that triages failed US PEO payroll syncs without an engineer starting it. The pipeline detects and batches failures, retries them, investigates the rest with parallel data fetches, classifies the cause and writes the fix command, then posts a per-failure summary to Slack. Deel deployed it on Akai, which the post calls the company's internal AI orchestration platform.
Fact · Reported · High confidence · `deel-payroll-incident-agents--summary`
Confidence reason: A linked first-party source states the claim.
Evidence:
- Supports · [1] [How Deel Eliminated 900 Engineering Hours of Firefighting with a 4-Agent AI System](https://www.deel.com/blog/900-engineering-hours-eliminated-with-akai/) · [Preserved copy](https://github.com/steel-experiments/internal-agents-map/blob/main/archive/sources/deel-payroll-incident-agents-source-1/content.md) · Preserved content.md, lines 30, 46, 52-64
Representative workflow: failed US PEO payroll sync through detection, retry, parallel investigation, classification, and a Slack handoff to an engineer.
## How it works
### Detect and batch the failures
Every few minutes the first stage scans the payroll system for failed syncs, deduplicates them, groups related failures, and hands a clean batch downstream without a Slack ping or a human trigger.

### Retry first, then investigate in parallel
The second stage fires an automatic retry on every failure. About 55% clear themselves. For the rest it fans out in parallel to check hire record state, pull monitoring logs, query the payroll database, and cross-reference compliance rules, so diagnosis lands in under 10 seconds across four systems.

### Classify the failure and write the fix
The third stage categorizes the failure against a taxonomy, decides whether it belongs to the employer, the employee, or Deel, and writes out the exact command needed to fix it.

### Deliver one Slack section per failure
The fourth stage packages the results into Slack with one section per failure, copy-paste fix commands, and direct log links. It also scans across cases and reports a repeated error from one company as a single employer-level setup issue instead of one alert per new hire.

## Where people stay involved
- **failed US PEO payroll sync → automatic retry that clears the failure** — Exception-only · Level 5
- **payroll sync failure that survives the retry → classified diagnosis and fix command delivered in Slack for an engineer** — Work-product review · Level 3
**Reported:** About 55% of cases self-resolve on the retry with no one touching them. The rest reach an engineer as a Slack section with the fix command, which the post describes as a 30-second review. The pipeline writes the command; the post does not report it running one.
### Supervision evidence
#### Operating model assessment
Level 5 for failed US PEO payroll sync → automatic retry that clears the failure; human attention boundary: exception-only.
Inference · Catalog judgment · Medium confidence · `deel-payroll-incident-agents--operating-models-0`
Confidence reason: The post reports that the retry stage clears about 55% of failures and that those cases self-resolve without anyone touching them, which places human attention at the exception only. Deel does not say who watches the retries or whether a failed retry ever pages someone directly.

#### Operating model assessment
Level 3 for payroll sync failure that survives the retry → classified diagnosis and fix command delivered in Slack for an engineer; human attention boundary: work-product-review.
Inference · Catalog judgment · Medium confidence · `deel-payroll-incident-agents--operating-models-1`
Confidence reason: The post says the remaining cases still reach an engineer and arrive as a 30-second review with the exact fix command, so a person reviews the work product before it takes effect. The post does not say whether an engineer may also reject or edit the proposed command.

## Implementation details
### Harness
Four stages run in sequence on Akai, described as Deel's internal AI orchestration platform. Each stage owns one job and hands off to the next with no manual intervention and no engineer to start the run.

### Tool access
Scans the payroll system for failed syncs and fires retries against them. For failures that survive a retry it checks hire record state, pulls logs from monitoring systems, queries the payroll database, and cross-references employment compliance rules. It writes the fix command rather than running it, and posts the result to Slack with direct log links.

### Implementation coverage
- **Model:** unreported — No model, vendor, or version is named. The post refers to a prompt change, which implies a language model, but naming one would be a guess.
- **Harness:** reported
- **Sandbox:** unreported — The post names Akai as the host platform but documents no execution isolation boundary; the legacy unknown claim stays in research details.
- **Tool access:** reported
- **Knowledge:** reported
- **Context management:** reported
- **Credentials:** unreported — How the pipeline authenticates to the payroll system, the hire record database, the monitoring logs, and Slack is not documented.
- **Interfaces:** reported
**Unreported:** The post reports no test, evaluation, or accuracy check on the classifications or the generated fix commands, and no rate of wrong diagnoses.
## Reported observations
Observation: Cost latency · Estimate · Engineering hours Deel reports it no longer spends investigating failed US PEO payroll syncs, given as 900+ per year
### Headline claim
Deel reports 900+ engineering hours reclaimed annually
Metric · Reported · Low confidence · `deel-payroll-incident-agents--headline-metric`
Confidence reason: Deel reports the annual figure in its own marketing-adjacent blog as a single table row with no measurement window, no case count, and no method for converting saved triage time into annual hours.
Qualifications:
- The source does not report the denominator of this figure.
- Reported by: Deel
- Scope: Engineering hours Deel reports it no longer spends investigating failed US PEO payroll syncs

Observation: Cost latency · Reported measurement · Time to triage one failed US PEO payroll sync, 45 minutes before and under 10 seconds after
### Key observation
Time per triage fell from 45 minutes to under 10 seconds
Metric · Reported · Medium confidence · `deel-payroll-incident-agents--key-metrics-0`
Confidence reason: Deel reports the before-and-after pair in its own blog. The 45 minutes matches the narrative description of the old triage, and the under-10-seconds figure matches the parallel-fetch description, but no sample, date range, or timing method is given.
Qualifications:
- The source does not report the denominator of this figure.
- Reported by: Deel
- Scope: Time to triage one failed US PEO payroll sync, before and after the pipeline

Observation: Effectiveness · Reported measurement · Share of failed US PEO payroll syncs resolved without an engineer, 0% before and 55% after
### Key observation
Auto-resolved cases rose from 0% to 55%; about 55% of cases now self-resolve without anyone touching them
Metric · Reported · Medium confidence · `deel-payroll-incident-agents--key-metrics-1`
Confidence reason: Deel reports both the 0% to 55% table row and the matching prose, and separately reports that about 55% of failures were transient, which makes the number internally consistent. It is self-reported and the counting period is not given.
Qualifications:
- Reported by: Deel
- Scope: Share of failed US PEO payroll syncs resolved without an engineer, before and after the pipeline
- Denominator: All failed US PEO payroll syncs the pipeline picks up

Observation: Runtime capacity · Estimate · Failed payroll sync cases handled at peak, a full engineering day for 4-6 cases before and 20+ at the same time after
### Key observation
Peak capacity rose from a full engineering day for 4-6 cases to 20+ cases at the same time
Metric · Reported · Low confidence · `deel-payroll-incident-agents--key-metrics-2`
Confidence reason: Both sides of this comparison are ranges rather than counts, the post gives no measured peak day, and 20+ cases is an open-ended figure.
Qualifications:
- The source does not report the denominator of this figure.

## Lessons
### Lesson
Deel runs its stages in sequence but fires the investigation stage's data fetches at the same time, and reports that this parallel fan-out is the difference between a 40-second and a 10-second operation.
Fact · Reported · Medium confidence · `deel-payroll-incident-agents--lessons-learned-0`
Confidence reason: The post states the sequential-stage and parallel-fetch design and gives the 40-second to 10-second comparison as the result. The comparison is Deel's own and carries no measurement method.

### Lesson
Deel keeps the failure taxonomy in the classification stage's prompt, so a new failure category found in production is a one-line prompt change.
Fact · Reported · Medium confidence · `deel-payroll-incident-agents--lessons-learned-1`
Confidence reason: The post names the structured failure taxonomy and states that adding a category is a one-line prompt change. It does not show the prompt or say how a new category is tested.

### Lesson
Deel passes clean JSON between stages so that the stages share no state and carry no interdependencies.
Fact · Reported · Medium confidence · `deel-payroll-incident-agents--lessons-learned-2`
Confidence reason: The post states the JSON-in, JSON-out handoff and the absence of shared state as a design choice. It reports no failure mode this choice avoided in production.

### Lesson
Deel retries every payroll sync failure immediately, measures what share clears itself, and investigates only the remainder; the team notes a retry on a payroll record is only safe once the diagnosis runs anyway.
Fact · Reported · Medium confidence · `deel-payroll-incident-agents--lessons-learned-3`
Confidence reason: The post states the retry-first ordering and gives Deel's reason, that a retry on a payroll record is only safe once the diagnosis runs anyway. It does not report a case where a retry compounded a structural failure.

### Lesson
Deel states that the pattern is not specific to its payroll system and maps onto other high-volume, low-signal triage work such as API failures, database incidents, and support escalations. The post reports no second Deel workflow that uses it.
Opinion · Reported · Medium confidence · `deel-payroll-incident-agents--lessons-learned-4`
Confidence reason: This is Deel's own generalization of its result, stated in the closing section of a post that also markets the Deel platform. The post names no second workflow at Deel or elsewhere that runs the pattern, so the transfer is asserted rather than shown.
