gws is a command-line tool that provides one interface to Google Workspace services such as Drive, Gmail, Calendar, Sheets, Docs, Chat, and Admin. People and AI agents use it to automate Workspace tasks and receive structured JSON results, while its commands are generated dynamically from Google's Discovery Service. The catalogue contains skills and instructions for using gws.
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.

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 | $0.00017 | $0.00466 |
| Opus 5.5 | $0.00007 | $0.00186 |
| Sonnet 5.5 | $0.00003 | $0.00093 |
| Haiku 4.5 | $0.00002 | $0.00047 |
Grade A, and why
gws-sheets-append 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.

Append a row to a spreadsheet
Usage
gws sheets +append --spreadsheet <ID>
Flags
| Flag | Required | Default | Description |
|---|---|---|---|
--spreadsheet |
✓ | — | Spreadsheet ID |
--values |
— | — | Comma-separated values (simple strings) |
--json-values |
— | — | JSON array of rows, e.g. '[["a","b"],["c","d"]]' |
--range |
— | A1 |
Target range in A1 notation (e.g. 'Sheet2!A1') to select a specific tab |
Examples
gws sheets +append --spreadsheet ID --values 'Alice,100,true'
gws sheets +append --spreadsheet ID --json-values '[["a","b"],["c","d"]]'
gws sheets +append --spreadsheet ID --range "Sheet2!A1" --values 'Alice,100'
Tips
- Use --values for simple single-row appends.
- Use --json-values for bulk multi-row inserts.
- Use --range to append to a specific sheet tab (default: A1, i.e. first sheet).
[!CAUTION] This is a write command — confirm with the user before executing.

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.
