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 | $0.00034 | $0.01768 |
| Opus 5 | $0.00017 | $0.00884 |
| Sonnet 5 | $0.00007 | $0.00354 |
| Haiku 4.5 | $0.00003 | $0.00177 |
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 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.

Google Sheets
Spreadsheet operations built for how small businesses actually track data.
Uses the gws CLI for all Sheets operations. See the google-workspace skill for setup.
Triggers
- "read the spreadsheet"
- "update the sheet"
- "add a row to..."
- "create a spreadsheet"
- "pull data from sheets"
- "log this to a spreadsheet"
- Any request involving spreadsheet read/write operations
Prerequisites
gwsCLI installed and authenticated with Sheets + Drive scope- Run
gws auth login -s sheets,driveif not already done
Core Commands
gws sheets +read # Read values from a spreadsheet
gws sheets +append # Append a row to a spreadsheet
gws sheets spreadsheets create # Create a new spreadsheet
gws sheets spreadsheets get # Get spreadsheet metadata
Common Operations
Read data from a sheet
# Read a range
gws sheets +read
# When prompted: spreadsheet ID + range (e.g., "Sheet1!A1:D10")
# Read via API directly
gws sheets spreadsheets values get --params '{
"spreadsheetId": "SPREADSHEET_ID",
"range": "Sheet1!A1:D100"
}'
# Read entire sheet
gws sheets spreadsheets values get --params '{
"spreadsheetId": "SPREADSHEET_ID",
"range": "Sheet1"
}'
Append a row
# Append a single row
gws sheets +append
# When prompted: spreadsheet ID, range, values
# Append via API directly
gws sheets spreadsheets values append --params '{
"spreadsheetId": "SPREADSHEET_ID",
"range": "Sheet1!A:D",
"valueInputOption": "USER_ENTERED"
}' --json '{
"values": [["2026-01-15", "Widget A", "50", "$12.50"]]
}'
Write / Update cells
# Update a specific range
gws sheets spreadsheets values update --params '{
"spreadsheetId": "SPREADSHEET_ID",
"range": "Sheet1!B2",
"valueInputOption": "USER_ENTERED"
}' --json '{
"values": [["updated value"]]
}'
# Batch update multiple ranges
gws sheets spreadsheets values batchUpdate --params '{
"spreadsheetId": "SPREADSHEET_ID"
}' --json '{
"valueInputOption": "USER_ENTERED",
"data": [
{"range": "Sheet1!A1", "values": [["Revenue"]]},
{"range": "Sheet1!B1", "values": [["Date"]]},
{"range": "Sheet1!A2", "values": [["$1,250"]]}
]
}'
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 pbc-os/smb-starter-kit (10 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 1,768 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 2026-08-31.
