Resume

What this agent does

The Quality Control Agent AI audits lending operations files at scale — applying a risk-tier sampling strategy that concentrates review resources on high-risk files while maintaining statistical visibility across the full portfolio, tagging every identified error against a standardised 20-category taxonomy, and routing specific, actionable feedback to the originating ops agent within 24 hours. It replaces the manual QC reviewer team with a continuous, systematic audit capability that catches errors before they accumulate into systemic failures, and gives the ops head a real-time quality dashboard instead of a lagging monthly sample.

Primary functions

Risk-Tier File Sampling

Daily · stratified across all processed files

Invoked when: the daily file batch is available in the LOS — sampling runs and audits complete within business hours

  • Stratifies every day's processed files into three risk tiers before sampling — high-risk (first-time applicants, high loan amounts above the 80th percentile of the product's disbursed amount distribution, applicants from geographies with elevated historical error rates, or files processed by agents with a current error rate above 10%), medium-risk (standard applicants with no elevated risk factors), and low-risk (returning borrowers with clean prior file history processed by agents with error rates below 5%). The stratification is recalculated daily based on current data — a geography's risk tier is updated weekly as its error rate trend changes.
  • Applies differential sampling rates to each tier: 100% of high-risk files, 30% of medium-risk files, and 10% of low-risk files. This concentrates audit resources where errors are most likely and most consequential — a first-time high-value applicant file with an error that reaches disbursement creates a much larger credit and compliance exposure than the same error in a low-risk file. The 100% high-risk coverage ensures no high-risk file escapes audit; the statistical sampling of lower tiers provides error rate visibility without proportional resource cost.
  • Escalates any agent to 100% file audit coverage when their personal error rate exceeds 15% across the prior week's audited files — ensuring that the agent's full output is checked until their error rate returns to threshold. An agent whose 30% sample shows 15% errors has an expected full-file error rate that is unacceptable; the 100% coverage confirms the extent of the problem and provides the supervisor with a complete picture of the agent's output quality.
Output: Daily audit sample — file count by risk tier, sampling rate applied, files selected for audit. Agent escalation to 100% coverage when error rate threshold is breached. Sampling strategy log for the ops head — transparent record of which files were audited and why.

Error Tagging

Per audited file · 20-category taxonomy · within 24 hours

Invoked when: a file is selected for audit — error tagging is completed and tags are applied to the file record within 24 hours of selection

  • Checks every audited file against the 20-error taxonomy — the standardised set of operational errors that covers the full range of file quality issues observed across the lending operation: missing mandatory document (5 sub-categories by document type), expired document, illegible document, name mismatch (minor and significant variants treated separately), address inconsistency, income figure transcription error, income figure inconsistency across documents, bank statement period gap, application form field incomplete, application form field incorrect (data entry error rather than missing), signature absent, photograph non-compliant, co-applicant KYC incomplete, guarantor declaration absent, credit bureau report stale (older than the 30-day policy limit), LTV calculation error, interest rate applied incorrectly to product, disbursement amount mismatch vs sanction letter, and processing fee calculation error. Each error is tagged to exactly one category; multi-error files receive one tag per error.
  • Distinguishes between critical errors (those that would prevent the file from being legally enforceable or regulatorily compliant — missing mandatory KYC document, guarantor declaration absent, disbursement amount mismatch vs sanction letter) and standard errors (those that reduce operational quality but do not affect enforceability — transcription errors, bank statement gaps, photograph non-compliance). Critical error files are escalated to the supervisor immediately; standard error files receive the standard 24-hour feedback routing.
  • Records the agent responsible for each error — matched from the LOS processing record — enabling agent-level error rate tracking. Where a file has been processed by multiple agents at different stages, the error is attributed to the agent who was responsible for the stage in which the error occurred, not to the final agent in the processing chain.
Output: Error tag list per audited file — error category, criticality (critical / standard), responsible agent, and stage of error. Critical error escalation to supervisor within 2 hours. Standard error feedback routing within 24 hours. Error tags stored in the file record and the agent performance database.

Agent Feedback Loops

Per error · agent feedback card within 24 hours · weekly pattern report

Invoked when: an error is tagged — feedback card dispatched to the responsible agent within 24 hours; weekly pattern analysis runs every Monday

  • Dispatches a structured feedback card to each agent for every error in their audited files — identifying the specific file (by reference number, not borrower name), the specific error category, the exact field or document where the error occurred, the correct standard that was not met, and the corrective action required. The feedback card is not a performance warning — it is a coaching tool. The language is instructive, not punitive: "the bank statement attached covers March–May; the policy requires the 3 most recent months, which at the application date (June 14) means April–June. Please request the updated statement." Specific, actionable feedback is more effective at reducing recurrence than a generic error notification.
  • Tracks each agent's error history across a 12-week rolling window — building the dataset that distinguishes a one-off error (an agent who makes this error once in 12 weeks) from a recurring pattern (an agent who makes the same error consistently). Recurring errors — the same error category appearing in an agent's audited files for three or more consecutive weeks — are escalated to the supervisor with the full 12-week history, indicating that the agent has received feedback on this error but has not corrected it. The supervisor's intervention is the next level of coaching, not an HR action.
  • Produces a weekly ops QC dashboard for the ops head — showing error rates by category, by agent, and by branch for the current week and the prior 4-week trend. The category breakdown tells the ops head where process or training gaps exist across the team; the agent breakdown tells them where individual coaching is needed; the branch breakdown tells them whether quality problems are concentrated in specific locations that may have supervisory or infrastructure issues.
Output: Agent feedback card per error — specific, actionable, and dispatched within 24 hours. Recurring error escalation to supervisor — 12-week history attached. Weekly ops QC dashboard — error rates by category, agent, and branch with 4-week trend. Monthly systemic error report to CCO — categories where error rates are rising and training or policy recommendations.

Knowledge base

20-Error Taxonomy

The standardised error categories used for tagging, agent feedback, and pattern analysis. Approved by the ops head and updated when new error types emerge. The consistency of the taxonomy is the foundation of the trend analysis.

LOS — Daily File Batch and Processing Records

All files processed in the prior 24 hours — the population for risk-tier stratification and sampling. Agent processing records used for error attribution.

Risk-Tier Stratification Model

The criteria for assigning files to high, medium, and low risk tiers — updated weekly based on current error rate data by geography, agent, and product type.

Agent Error History — 12-Week Rolling Record

Per-agent error rates and error categories across the prior 12 weeks — the dataset for recurring error detection and the supervisor escalation evidence base.

Document and Process Standards Library

The correct standards for each document type, data field, and process step — the reference against which errors are identified and the basis for the corrective action in each feedback card.

Pre-Training — Lending Operations Quality Control Knowledge

File quality audit methodology, risk-based sampling design, and ops error taxonomy best practices for lending operations up to knowledge cutoff.

Hard guardrails

Will notMake any credit or compliance decision. QC audits operational file quality; credit and compliance assessments are separate processes with separate authorities. A clean QC result does not indicate creditworthiness or regulatory compliance.
Will notTake disciplinary action against agents. Agent feedback cards are coaching tools; recurring error escalations are supervisor notifications. HR and disciplinary actions are management decisions made by the ops supervisor and HR — informed by QC data but not dictated by it.
Will notUpdate the error taxonomy without ops head approval. Taxonomy changes affect all historical error rate comparisons and all agent feedback consistency. New error categories are proposed to the ops head when they emerge from the audit data; they are not activated until approval is recorded.
Will notAttribute a critical error to an agent without confirming the processing record. Critical errors trigger immediate supervisor escalation — attribution must be confirmed against the LOS processing log before the escalation is sent, to avoid escalating an error to the wrong agent's supervisor.

Known limitations

The risk-tier stratification is based on the factors observable in the LOS at the time of sampling — it cannot account for file quality risks that are only visible through manual review of the underlying documents. A file that appears low-risk by the stratification criteria may contain a document quality issue (a subtly altered photograph, a bank statement with an internal date inconsistency) that the automated stratification does not detect.Maintain a random 5% spot-check across all tiers — including low-risk files — as a calibration sample. If the spot-check consistently finds error rates above the expected low-risk baseline in a category, it indicates the stratification model is understating risk for that category and needs recalibration.
The 20-error taxonomy covers the error types observed to date — new products, new geographies, or regulatory changes may introduce error types not yet in the taxonomy. Until the new error type is formalised and added to the taxonomy, it will be tagged as "other" with a free-text description, which limits its inclusion in trend analysis and agent feedback.Review the "other" tag volume monthly — a high volume of "other" tags indicates that new error patterns are emerging that warrant taxonomy addition. The ops head reviews the free-text descriptions of "other" tags to identify candidates for formalisation.
