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 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.

API Resources

spreadsheets

  • batchUpdate — Applies one or more updates to the spreadsheet. Each request is validated before being applied. If any request is not valid then the entire request will fail and nothing will be applied. Some requests have replies to give you some information about how they are applied. The replies will mirror the requests. For example, if you applied 4 updates and the 3rd one had a reply, then the response will have 2 empty replies, the actual reply, and another empty reply, in that order.
  • create — Creates a spreadsheet, returning the newly created spreadsheet.
  • get — Returns the spreadsheet at the given ID. The caller must specify the spreadsheet ID. By default, data within grids is not returned. You can include grid data in one of 2 ways: * Specify a field mask listing your desired fields using the fields URL parameter in HTTP * Set the includeGridData URL parameter to true.
  • getByDataFilter — Returns the spreadsheet at the given ID. The caller must specify the spreadsheet ID. For more information, see Read, write, and search metadata. This method differs from GetSpreadsheet in that it allows selecting which subsets of spreadsheet data to return by specifying a dataFilters parameter. Multiple DataFilters can be specified.
  • developerMetadata — Operations on the 'developerMetadata' resource
  • sheets — Operations on the 'sheets' resource
  • values — Operations on the 'values' resource

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.
