Earnings-quality forensics — Beneish M-Score, Altman Z, Sloan accruals ratio, cash-vs-earnings divergence, SBC-adjusted FCF, revenue-recognition and capitalisation checks, auditor and related-party flags, scored as a Manipulation Risk Score 0–10.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Forensic Accounting — Are the Reported Earnings Real?

## ⚠️ Data Verification — Do This Before Any Analysis

Before running any analysis, always retrieve the latest market data for the ticker:

1. **Fetch current price** — use web search or ask the user for the live price, 52-week range, and market cap. Never assume a price from training data. (Market cap feeds Altman's X4; everything else in this skill comes from the filings.)
2. **Pull the filings, not a data feed** — this skill needs **at least two, preferably three to five, consecutive fiscal years** of as-filed statements, plus their notes:
   - **10-K Item 8**: income statement, balance sheet, cash-flow statement (for every index below you need year *t* and year *t−1*).
   - **Revenue note** (ASC 606): disaggregation, contract assets / **unbilled receivables**, deferred revenue, remaining performance obligations, any bill-and-hold or principal-vs-agent judgment.

How to install

The exact contents, by fingerprint
mdr add yennanliu/investskill/forensic-accounting@sha256:fcaed90998d518fe

The line at the top of this page pins the label git:20261024.1726f29, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
