spreadsheet-auditor skillA
spreadsheet-auditor is agent-read markdown (skill) from petehottelet/spreadsheet-auditor: Audits an existing Excel workbook or financial model (.xlsx, .xlsm) for errors and pins each to a cell: #REF! and other live errors, broken references, totals that skip rows or double-count, formulas that break the pattern of their neighbors, hardcoded plugs, circular references, hidden rows or sheets feeding totals, and row and column totals that do not tie out. Use when someone wants a spreadsheet they already have checked, reviewed, audited, QA'd or debugged: finding the mistakes before a mod.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Spreadsheet Auditor `scripts/audit.py` finds candidate defects and pins each to a cell. It matches patterns and cannot see intent: on real workbooks about one finding in four is a false alarm, usually a total, net or summary line that differs from its neighbors by design. Run it, check each candidate in context, and tell the user what is actually wrong. The user's workbook is read-only throughout. ## Workflow Copy this checklist and work through it: - [ ] 1. Run the audit - [ ] 2. Read the summary and the report - [ ] 3. Check each candidate in context - [ ] 4. Answer the user ### 1. Run the audit ```bash python scripts/audit.py WORKBOOK --out audit_report.md --json findings.json --summary ``` Write the outputs in the user's working folder. Exit codes 0, 1 and 2 all mean the audit finished (1: Critical findings present); 3 to 5 mean it did not, and stderr says why: - openpyxl missing: run `pip install openpyxl` (Python 3.11+), then rerun. - `.xls`, `.xlsb`, `.ods` or a password-protected file: convert with `soffice --headless --convert-to xlsx FILE` when LibreOffice is installed, otherwise ask for an unprotected `.xlsx`. Say which copy you audited. …

mdr add petehottelet/spreadsheet-auditor/spreadsheet-auditor@git:20260923.2887803mdr add petehottelet/spreadsheet-auditor/spreadsheet-auditor@sha256:7f80161d32208408Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
