Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00045 | $0.00519 |
| Opus 5 | $0.00023 | $0.00260 |
| Sonnet 5 | $0.00009 | $0.00104 |
| Haiku 4.5 | $0.00005 | $0.00052 |
Grade A, and why
spreadsheet-management 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 6d 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
When the user asks about spreadsheets or data in Google Sheets, use the gsheets MCP tools.
When to Use This Skill
Activate when the user:
- Wants to read spreadsheet data ("Get data from sheet", "Read column A")
- Needs to write data ("Update cell A1", "Add a row", "Append data")
- Formats cells ("Make header bold", "Add borders", "Change colors")
- Creates charts ("Create a bar chart", "Add a pie chart")
- Manages sheets ("Create new sheet", "Delete sheet", "Copy sheet")
Tools Reference
| Task | Tool |
|---|---|
| Read range | sheets_get_values |
| Read multiple | sheets_batch_get_values |
| Get info | sheets_get_metadata |
| Write range | sheets_update_values |
| Append rows | sheets_append_values |
| Insert rows | sheets_insert_rows |
| Format cells | sheets_format_cells |
| Borders | sheets_update_borders |
| Merge | sheets_merge_cells |
| Create chart | sheets_create_chart |
| New sheet | sheets_insert_sheet |
Spreadsheet ID
Found in the URL: https://docs.google.com/spreadsheets/d/{SPREADSHEET_ID}/edit
Range Notation
Sheet1!A1:D10 # Specific range
Sheet1!A:A # Entire column
Sheet1!1:1 # Entire row
A1:D10 # First sheet, specific range
'Sheet Name'!A1 # Sheet name with spaces
Example Workflows
Read and summarize:
sheets_get_metadata spreadsheetId="1Bxi..."
sheets_get_values spreadsheetId="1Bxi..." range="Data!A1:F100"
Format header row:
sheets_format_cells spreadsheetId="1Bxi..." range="A1:Z1" bold=true backgroundColor="#4285f4"
Create chart:
sheets_create_chart spreadsheetId="1Bxi..." sheetId=0 chartType="BAR" dataRange="A1:B10"
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.

spreadsheet-management is a skill published in the GitHub repository freema/mcp-gsheets (97 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 519 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
