dr-audit

An audit-support package that checks whether financial data is complete, reconciles correctly, maps accounts consistently, and passes sample tests.

In plain words
What is it for?
Use it to support management reviews and auditors with evidence from FinanceOS data; it is not a full SOX certification.
Why use it?
It turns supported data checks into a PDF report and an Excel evidence workbook, while clearly separating them from controls the data cannot prove, such as access control.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dr-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 499 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Audit Evidence Package

Generate an audit-support evidence package over FinanceOS data — the control checks that this data surface can actually evidence, packaged for management and auditors.

Creates both a PDF report (for management) and an Excel evidence workbook (for the audit trail).

Honest scope — read first. This is not a SOX certification. In scope are the data-evidencable control families: completeness & period integrity, consistency/reconciliation, account-mapping integrity, and substantive sampling — each backed by a real query this skill can run. Access control, change management, and IT general controls are out of scope: the FinanceOS MCP surface has no audit-log, access-history, or user-activity endpoint, so those control families require system-administration evidence outside this tool's reach. Never present a control result this skill cannot substantiate with a tool call — the evidence workbook carries a mandatory "Out of scope — requires external evidence" sheet so no reader mistakes the package for full SOX coverage.

Excel Context — Routing Preamble

Before any data pull, establish whether this skill is running in a live Excel context (Claude for Excel with the Datarails Add-In loaded) and route accordingly.

Detect — never infer from the user's wording. A sheet list containing __dr_agent means the add-in is loaded. Confirm with the agent.get_session probe, which you run by executing Office.js through the execute_office_js tool (see the Excel Context Contract in CLAUDE.md, §Transport) — it is not an MCP tool and has no MCP equivalent. A failed probe is a normal detection result, not an error: it means "no bridge here", which is the expected outcome in Claude Code. Do not surface it, do not retry it, and do not apply this skill's connection-error or Connectors-UI guidance to it — that guidance is about datarails-finance-os connector calls only. A successful probe means Excel context, on either transport. The bridge serves two add-in tracks and their session payloads differ: Flex (Office.js task pane) exposes isLoggedIn; the COM desktop add-in — the majority of live workbooks — exposes isConnected instead, and isConnected: false is not a login failure, an error, or a reason to stop or send the user anywhere. It merely means the workbook isn't connected to a Datarails file, which matters only to drilldown_* / create_dynamic_range (the bridge skill gates those itself). Only Flex's explicit isLoggedIn: false means sign-in is needed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
