Is the Sheets CLI skill free?

Yes. The skill itself is free from gmickel/sheets-cli. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Sheets CLI SkillProof Score?

8.0/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 3/5.

How do I install Sheets CLI?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Sheets CLI with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 8.0/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · d0a023a

SKILL.md says the CLI is 'already installed... no installation needed,' but the repo's own README requires a Bun build plus a full Google Cloud OAuth setup before any command runs — real friction the skill body doesn't disclose.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Sheets CLI does

sheets-cli wraps the Google Sheets and Drive APIs in a JSON-in/JSON-out CLI: find a spreadsheet by name, read a sheet as structured rows, append rows, and update cells by key column or row index. It triggers when a user asks to read, update, or append to a Google Sheet, or names a specific sheet/tab. Best used with its documented read-decide-dry-run-apply workflow so writes are previewed before they land.

How to install Sheets CLI

git clone https://github.com/gmickel/sheets-cli

mkdir -p ~/.claude/skills
cp -r . ~/.claude/skills/sheets-cli
# prerequisite: sheets-cli auth login --credentials <oauth-client.json> (Sheets + Drive APIs enabled in GCP)

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
