Represent rectangular datasets as CSV or TSV when repeated JSON field names add unnecessary payload size.
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
# Tabular Serialization Protocol (CSV / TSV over JSON Arrays) ## Overview When an LLM extracts or analyzes tabular datasets (*e.g., customer transaction lists, database query results, or server metric logs*), defaulting to an array of JSON objects forces the model to repeat **every column key on every single row** (*`"first_name": "...", "transaction_amount": "...", "status": "..."`*). In a 100-row dataset, repeating JSON keys burns **thousands of redundant tokens** purely on structural quotation marks, colons, and braces. The **Tabular Serialization Protocol** replaces JSON object arrays with **Comma-Separated Values (CSV)** or **Tab-Separated Values (TSV)** - defining the header keys once at row 1 and streaming raw comma-delimited data rows, cutting token usage by **65% to 75%**. --- ## JSON Object Array vs. CSV Data Stream ``` ┌─────────────────────────────────────────────────────────────┐ │ Tabular Payload Comparison │ │ │ │ JSON Object Array (145 Tokens for 2 Rows): │ │ [ │ …

How to install
mdr add alivirgo/major-ai-skills/csv-over-json-tables@sha256:82af25c0085f2ca7The line at the top of this page pins the label git:20260911.25436b5, 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.
