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
# Spreadsheets Handle tabular data with exact values, minimal diffs, recipient-scoped data handling, atomic writes, and structural validation. ## Invariants 1. Keep precision-sensitive amounts as strings and compute with `decimal.Decimal` or DuckDB `DECIMAL(38, 18)`, never binary floats. 2. Touch only requested rows, columns, formulas, and formatting. Existing file conventions override house defaults. 3. For newly authored text tables, prefer TSV, UTF-8 without BOM, LF, one trailing newline, lowercase `snake_case` headers, ISO dates, `.` decimals, and `-` nulls. 4. Read unknown text tables with BOM-tolerant UTF-8. Never write a BOM. 5. Write in place atomically through a sibling temporary file, validate it, then replace the target. 6. Escape external cells beginning with `=`, `+`, or `@`. A bare `-` null is exempt. Formula-prefix cells in trusted authored data are observations, not proof of injection. 7. Treat transaction, bank, exchange, and tax data as user-owned. Use unredacted samples in internal agent reports when materially useful. For public or third-party disclosures, or when the user asks, use `--redact-samples`. ## Factual Profiling …

How to install
mdr add paulrberg/agent-skills/spreadsheets@sha256:7eed644d4c60dacaThe line at the top of this page pins the label git:20261005.322d94f, 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.
