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.

Security

Grade A, and why

google-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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/sheets_operations.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Google Sheets

Read, write, and manage Google Sheets via OAuth authentication.

Pre-Flight Check (ALWAYS FIRST)

Quick Reference

Read Data

uv run python 00-system/skills/google/google-sheets/scripts/sheets_operations.py read <spreadsheet_id> "Sheet1!A1:D10"

Write Data

uv run python 00-system/skills/google/google-sheets/scripts/sheets_operations.py write <spreadsheet_id> "Sheet1!A1" --values '[["Name", "Amount"], ["Contract A", 5000]]'

Append Rows

uv run python 00-system/skills/google/google-sheets/scripts/sheets_operations.py append <spreadsheet_id> "Sheet1!A:D" --values '[["New Row", "Data", "Here", "Now"]]'

Get Sheet Info

uv run python 00-system/skills/google/google-sheets/scripts/sheets_operations.py info <spreadsheet_id>

List Spreadsheets

uv run python 00-system/skills/google/google-sheets/scripts/sheets_operations.py list --query "tracking"

Create Spreadsheet

uv run python 00-system/skills/google/google-sheets/scripts/sheets_operations.py create "New Spreadsheet" --sheets "Data" "Summary"

Common Workflows

Extract Data -> Update Sheet

from sheets_operations import append_rows

data = [
    ["Contract A", "2024-01-15", 5000, "Active"],
    ["Contract B", "2024-02-01", 7500, "Pending"]
]
result = append_rows(spreadsheet_id, "Contracts!A:D", data)
print(f"Added {result['updated_rows']} rows")

Batch Update Multiple Cells

from sheets_operations import batch_update

data = [
    {"range": "Sheet1!A1", "values": [["Header 1"]]},
    {"range": "Sheet1!B1", "values": [["Header 2"]]},
]
batch_update(spreadsheet_id, data)

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
