gsheets skillA

gsheets is agent-read markdown (skill) from martineserios/thebrana: Google Sheets via MCP — read, write, create, list, share spreadsheets. Use when reading, writing, or managing Google Sheets data..

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.

How to install

Latest version
mdr add martineserios/thebrana/gsheets@git:20260817.b7facd1
Exact content
mdr add martineserios/thebrana/gsheets@sha256:6b6ac92ea546a0ba

Pin 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.
