What does the Cormac skill do?

Own the close: a real close calendar, internal controls that hold up, and financials ready for an auditor. Load it once into Claude Projects and you get a configured Financial Controller without re-explaining context at the start of every session. Verify current tax, payroll, and securities specifics with a licensed CPA, EA, payroll provider, or attorney before acting. This skill handles the process and the numbers, not licensed advice.

How is this different from using Claude without the Cormac skill?

Without a skill file your AI starts every session as a general assistant. With Cormac loaded it applies Financial Controller methodology from the first message, with consistent quality every time. Verify current tax, payroll, and securities specifics with a licensed CPA, EA, payroll provider, or attorney before acting. This skill handles the process and the numbers, not licensed advice.

// what's inside

Drop Cormac into Claude and get a senior financial controller who closes the books on a calendar, builds real internal controls, and gets you audit-ready before an auditor asks.

Cormac owns the accounting function above the transaction level: a close calendar and checklist, segregation-of-duties and approval controls, GAAP-consistent internal financial statements, fixed-asset and depreciation schedules, intercompany eliminations and basic multi-entity consolidation, variance analysis with root-cause investigation, oversight of a bookkeeping or AP/AR team, ERP transition evaluation, and a PBC package ready for external auditors. Not a substitute for an audit opinion or tax advice, he says so and routes it to a CPA or audit firm.

What you get

→Close calendar with segregation-of-duties controls
→GAAP-consistent internal financial statements

# Cormac - Financial Controller

You are Cormac, a senior Financial Controller. You own the close calendar, internal controls, and GAAP-consistent internal financial statements.

## How you work
1. Build or fix the close calendar and controls
2. Review the general ledger before close, not after
3. Decompose variances to the real driver
4. Keep audit-ready documentation as you go

Not a licensed auditor or CPA for tax purposes. Route audit opinions and tax filing to a licensed firm.

Excerpt from the actual file you'll download.

// try it

prompt

$Our close takes three weeks and nobody can explain why margin moved 6 points last month. Fix the process and explain the variance.

Cormac returns a redesigned close calendar with named owners and deadlines, a segregation-of-duties control matrix, and a decomposed variance analysis (price, volume, mix, one-off) that names the actual driver, not a vague explanation.
