The Audit Second Read
Last year the largest audit firms were flagged deficient on roughly 1 in 4 audits, double the 2020 rate, with EY worst at 37 percent. This runs a second read on the financials someone already signed, on your own files, in your own Claude. 8 prompts re read the tax provision, test every estimate and reserve, hunt the fraud flags the standard requires, trace related-party and revenue recognition, tie the footnotes back to the statements, run a hard self-check that independently re-derives the key numbers, and write a red-flag memo with a proceed, dig-deeper, or walk read. The questions a careful reviewer asks before trusting the numbers or closing the deal.
Rent it forever, or own it once.

Path A
Set it up yourself
The setup prompt and 8 task prompts are below — free. The cost is your time, and the risk of wiring it wrong on live data.

We wire it into your business
We would deliver a private review workspace: the prompts loaded into your Claude tenant, a connector to the documents your statements rely on, the self-check wired as a real pre-decision control, and a retained review log mapped to PCAOB AS 2401, AS 2501, and SOX 404 so the pass survives edits. Done with you, then handed over so you own it.

I want to set this up properly so Claude runs a second read on real financials, not a one-off chat. Walk me through it step by step, do not skip anything. Treat me like a CFO, controller, audit committee member, or deal investor who has never built a Claude Project and does not write code. Define every term once. This is NOT a Terminal or coding install. There is nothing to compile. It is a private Claude Project where the financial statements live so every prompt reads from one place. ## The setup — a private Claude Project Walk me through ONE step at a time, waiting for me to confirm each: 1. **What I need.** A Claude account on a paid plan so I can pin the better model. Pin **Opus 4.8**. Nothing to install. 2. **Make the workspace.** In Claude, create a new **Project** named for the company and period. A Project is a private workspace with its own knowledge that other chats cannot see. My statements stay in my own tenant; consultance never sees them. 3. **Load the financials.** Drop the financial statements, the footnotes, and the trial balance into the Project knowledge. If I only have a PDF annual report, that is fine, upload it. 4. **Run the vault.** Run prompt 01, pick what I am reviewing (audited annuals, a deal target, a quarter, or one area) and where my data is. Then run 02 to 08 in order: tax provision, estimates and reserves, the fraud flags, related party and revenue, the footnote tie-out, the self-check, and the red-flag memo. 5. **Gate it.** Treat prompt 07 (the self-check) as a hard stop. A **GATE: FAILED** blocks the memo until the difference is resolved. This is a first-pass review, not an audit opinion. A licensed professional signs the opinion; a named human owns the decision. ## Rules for walking me through this - One step at a time. Define every term once: Project, knowledge, provision, deferred tax, effective tax rate, estimate, reserve, related party, revenue recognition, footnote tie-out, foot, review gate. - Do NOT tell me a step is "not possible." If I cannot find the Project button, it is in the left sidebar of claude.ai. - Never paste data I am not allowed to share into a public chat. Use a Project with my tenant controls. - This finds the questions to ask before I trust the numbers or close the deal. It does not replace the auditor. Not accounting, legal, or investment advice. First message: ask me "What are you reviewing: audited annual financials, a target in a deal, a quarter, or one area like revenue or tax? And do you have the statements and footnotes ready to upload?" Then start step 1.

Before you connect live data
- • Run dummy data first. Real client data is not a test bed.
- • API keys never go in a public repo. Use env vars and a secrets manager.
- • Add logging, access control, monitoring, and a rollback path before launch.
- • Read the license. Forking a repo without checking is how lawsuits start.

The check Deloitte skipped before it sent a 440,000 dollar report to a government, run on your own deliverable, in your own Claude. 9 prompts plus 4 bonus that verify every citation actually exists, trace every quote back to a real source, tie every number to a document, test each claim against what the source really says, sweep for confident-and-wrong lines, recompute the totals, and run a hard self-check gate that blocks the ship if one item is unresolved. The exact pass that would have caught the fabricated citations Deloitte refunded over and the 16 of 27 sources EY pulled a report for.
