A command-line skill for reading, writing, appending, and listing Google Sheets. A spreadsheet is a table of cells stored online and shared through Google Drive.

Listing spreadsheets, reading cell ranges, changing individual cells, and adding rows with the Google Sheets CLI.

It lets an agent update spreadsheet data through explicit commands and verify changes after writing or appending rows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.00535
Opus 5	$0.00027	$0.00267
Sonnet 5	$0.00011	$0.00107
Haiku 4.5	$0.00005	$0.00053

Security

Grade A, and why

gw-sheets scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Sheets

Invocation

CLI="python3 ${CLAUDE_PLUGIN_ROOT}/cli/gw.py"

Commands

$CLI sheets read SPREADSHEET_ID [--range "Sheet1!A1:F100"] --compact
$CLI sheets write SPREADSHEET_ID --range "Sheet1!E2" --value "bounced" --compact
$CLI sheets append SPREADSHEET_ID --values '["name","email","status"]' [--range "Sheet1"] --compact
$CLI sheets list --compact

Response Shapes (validated)

list: {"spreadsheets":[{"id","name","modified"}],"count":5}

read: {"spreadsheetId","range","rows":[["A1","B1"],["A2","B2"]],"count":2}

write: {"updated":true,"spreadsheetId","range","updatedCells":1}

append: {"appended":true,"spreadsheetId","range"}

Examples

# Read first 10 rows
$CLI sheets read "1BxiMVs..." --range "Sheet1!A1:F10" --compact

# Update a single cell
$CLI sheets write "1BxiMVs..." --range "Sheet1!E2" --value "sent"

# Append a new row (must be JSON array)
$CLI sheets append "1BxiMVs..." --values '["John","[email protected]","pending"]'

UI Verification

After write or append, verify the spreadsheet looks correct using Chrome DevTools MCP:

Open the sheet in the browser:

mcp__chrome-devtools__navigate_page → https://docs.google.com/spreadsheets/d/{spreadsheetId}/edit

Take a screenshot and confirm: the written/appended cells contain the expected values in the correct positions.
If data is wrong, fix it with sheets write before reporting done.

Notes

--values must be a JSON array string.
Range defaults to "Sheet1" if omitted on read/append.
Default account is main.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
