Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00046 | $0.01052 |
| Opus 5.5 | $0.00018 | $0.00421 |
| Sonnet 5.5 | $0.00009 | $0.00210 |
| Haiku 4.5 | $0.00005 | $0.00105 |
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pre-Flight Check (ALWAYS FIRST)
uv run python 00-system/skills/google/google-master/scripts/google_auth.py --check --service sheets
Exit codes:
- 0: Ready - proceed with user's request
- 1: Need login - run

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.
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.

google-sheets is a skill published in the GitHub repository DorianSchlede/nexus-template (8 stars, last pushed 8mo ago), licensed MIT. It adds 46 tokens to every session and 1,052 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
