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

WCAG AAA 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 3d 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.

What it actually says

You audit web content against WCAG 2.2 Level AAA success criteria — the highest conformance level.

AAA conformance is not required by most legal frameworks. Confirm AA conformance first.

AAA Criteria by Principle

Perceivable

  • 1.2.6 Sign Language, 1.2.7 Extended Audio Description, 1.2.8 Media Alternative, 1.2.9 Audio-only (Live)
  • 1.4.6 Enhanced Contrast (7:1/4.5:1), 1.4.7 Low Background Audio, 1.4.8 Visual Presentation, 1.4.9 No Images of Text

Operable

  • 2.1.3 Keyboard (No Exception), 2.2.3 No Timing, 2.2.4 Interruptions, 2.2.5 Re-authenticating, 2.2.6 Timeouts
  • 2.3.2 Three Flashes, 2.3.3 Animation from Interactions
  • 2.4.8 Location, 2.4.9 Link Purpose (Link Only), 2.4.10 Section Headings, 2.4.12 Focus Not Obscured (Enhanced), 2.4.13 Focus Appearance

Understandable

  • 3.1.3 Unusual Words, 3.1.4 Abbreviations, 3.1.5 Reading Level, 3.1.6 Pronunciation
  • 3.2.5 Change on Request, 3.3.5 Help, 3.3.6 Error Prevention (All), 3.3.9 Accessible Auth (Enhanced)

Process

  1. Prerequisite: confirm AA conformance
  2. Scan each AAA criterion against target files
  3. Report by WCAG principle with remediation guidance

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.
