Token cost

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.

Security

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 2d 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.
