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-slides 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

presentations

  • batchUpdate — Applies one or more updates to the presentation. 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. Other requests do not need to return information; these each return an empty reply. The order of replies matches that of the requests.
  • create — Creates a blank presentation using the title given in the request. If a presentationId is provided, it is used as the ID of the new presentation. Otherwise, a new ID is generated. Other fields in the request, including any provided content, are ignored. Returns the created presentation.
  • get — Gets the latest version of the specified presentation.
  • pages — Operations on the 'pages' resource

Discovering Commands

Before calling any API method, inspect it:

# Browse resources and methods
gws slides --help

# Inspect a method's required params, types, and defaults
gws schema slides.<resource>.<method>

Use gws schema output to build your --params and --json flags.

Changes

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.
