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

audit-accessibility 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.

--imageSource URL, file path, or base64 image to evaluate https://example.com/form.jpg
--mode Scan mode: quick (axe-core only) or deep (axe-core + AI analysis, default) --mode quick
--level WCAG compliance level: A (minimum), AA (standard), AAA (enhanced) --level AA
--wcag-version WCAG standard: 2.1 (compliance-focused) or 3.0 (outcome-focused) --wcag-version 3.0
--email Email for login (optional, if page requires authentication) --email [email protected]
--password Password for login (optional, if page requires authentication) --password MyPassword123
--design-system Path to DESIGN.md file for design-aware remediation (optional) --design-system ./DESIGN.md
--userPrompt Additional focus areas or custom instructions --userPrompt "check keyboard navigation for power users"

Mode Options

--mode quick — Fast automated scanning

  • Runs axe-core only (no API calls)
  • Immediate results
  • Catches low-hanging fruit (contrast, labels, semantic HTML)
  • Output: Markdown report + JSON findings
  • Best for: Quick feedback, CI/CD pipelines, catching obvious issues

--mode deep (default) — Comprehensive analysis

  • Runs axe-core first (automated findings)
  • Sends findings + screenshots to AI for deeper analysis
  • AI provides context, remediation code, design patterns
  • Output: Combined report (automated + AI insights)
  • Best for: Full audits, design-aware fixes, actionable guidance

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.
