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.

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 | $0.00045 | $0.00519 |
| Opus 5.5 | $0.00018 | $0.00208 |
| Sonnet 5.5 | $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 2mo 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 |

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 (104 stars, last pushed 4d ago), licensed MIT.

No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
create-pr
Creates a GitHub PR with a Linear-ticket-prefixed title and a decision-led, narrative description for Prisma 8. Use when the user wants to create a pull request, open a PR, or submit changes for review.
publish-npm-version
Cuts the next release of Prisma 8: bumps the root package.json version (on the v8 RC line: 8.0.0-rc.N → rc.N+1), propagates it to every workspace package, and opens a PR titled "chore(release): bump to ". When the maintainer merges the PR, the Publish to npm workflow runs automatically and ships the new version to npm…
triage-contributor-pr
Triage open pull requests from external contributors to prisma/orm and produce a per-PR verdict with evidence. Use when a maintainer asks to triage, evaluate, assess, or review the queue of incoming contributor PRs, to decide whether a fork PR is safe to run CI on, to check whether a PR is in scope for its version…
record-upgrade-instructions
Record upgrade instructions alongside a Prisma 8 breaking-change PR, so downstream consumers (users of @internal/ and authors of Prisma 8 extensions) can apply the matching code translation automatically via the published upgrade skills. Use when you have refactored framework code and the test suite went red in…
contrib-pr
Open a high-quality external contributor PR against prisma/orm. Use when the user is an outside contributor (not a Prisma maintainer) and wants to submit a change as a pull request from a fork. Encodes the contribution flow from CONTRIBUTING.md so the resulting PR passes review on the first round.
github-review-iteration
Orchestrates a GitHub PR review loop by delegating triage and implementation to dedicated sub-agents, then repeating until actionable review items are cleared. Use when the user says “address PR review”, “triage review comments”, or “iterate until review is clean”.
