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

cv-help 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 11d 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.

List windows and take a screenshot:

  1. Call cv_list_windows to see all open windows
  2. Find the HWND of the window you want
  3. Call cv_screenshot_window with that HWND

Click a button in an app:

  1. cv_screenshot_window to see the current state
  2. Identify the button coordinates from the screenshot
  3. cv_mouse_click at those coordinates

Drag and drop (works with WebView, UWP, Electron, WPF apps):

  1. cv_mouse_click(x=<END_X>, y=<END_Y>, start_x=<START_X>, start_y=<START_Y>, hwnd=<HWND>) — drag from start to end

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.
