Run IIA-Compliant Internal Audits with This Agent Skill

Where this fits

An audit manager asks an agent to execute a procurement review from the annual audit plan. The agent must define objectives, scope, procedures, sampling criteria, and working-paper references in one pass. This skill wraps those tasks in IIA Performance Standards, so the agent produces ready-to-review audit artifacts.

Why agents benefit

• Builds an audit program directly from IIA Standards 2200/2201, including objectives, scope, timing, and resource allocations.
• Calculates statistically defensible sample sizes using risk, population size, and expected error tolerance.
• Fills working-paper templates so evidence, conclusions, and review notes stay consistent and traceable.
• Generates walkthrough traces and interview questionnaires for document testing and field interview preparation.
• Cites IIA standards in the agent's reasoning, so audit committees see the rationale behind procedures.

Practical scenarios

Procurement audit kickoff

The agent receives the procurement risk register and prior findings, then produces a complete engagement plan: objectives, scope, procedures, staffing, and timeline, aligned to IIA 2200.

Fraud-focused expense testing

Expense claim fraud risk is high. The agent uses the sampling calculator to size the test, documents deviations in working papers, and prepares interview questions for the key approvers.

Advisory review of a new control design

Management asks for consulting support on a new CRM access model. The agent adapts the IIA framework to a lighter-touch objective, creates a walkthrough plan, and issues a memo with observations rather than a formal assurance rating.

Add it to your agent workflow

Install the skill from the AriaAI repository:

npx skills add guoliang1114-boop/AriaAI --skill internal-audit-execution

Then instruct the agent with a concrete outcome:

Run an internal audit engagement for the vendor payment process. Use audit-program-builder to create a program compliant with IIA 2200/2210, then apply sampling-calculator to plan tests for a 2% error tolerance.

The agent will assemble the audit program, calculate the sample size, and fill the working paper template before requesting your review.

Compare before adopting

Before adopting, compare against your current stack. Inspect the README for clarity, IIA standard mappings, and whether the tools match the audit types your agents handle. Check maintenance freshness and last-updated date. Consider alternatives: generic document-generation agents can draft audit programs, but without an IIA structure they may not be defensible. Finally, evaluate workflow fit—can the tools integrate with your existing knowledge base, or are you locked into one agent workflow?

Why it is worth tracking

This skill is worth tracking because it sits at a useful intersection: internal audit procedures are templateable, but applying them to real engagements requires adherence to professional standards. With 37 stars and a stable 1.0.0 release, it is early but has a clear quality signal. Re-evaluate as the repository gains commits and user reviews.
