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 | $0.00017 | $0.00466 |
| Opus 5 | $0.00009 | $0.00233 |
| Sonnet 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 9d 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.
This is a copy
100% identical to gws-sheets-append — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says

PREREQUISITE: Read

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.
