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 1mo 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.

Audit Accessibility

Audit web page or component for accessibility issues and WCAG compliance.

Your Task

Perform accessibility audit and provide remediation recommendations.

Arguments

  • $1: File path or URL to audit

Steps

  1. Read the code or page:

    • Parse HTML/JSX structure
    • Identify interactive elements
    • Check for ARIA attributes
  2. Check critical issues:

    Missing alt text:

    • Find all <img> tags
    • Check for alt attribute
    • Flag decorative images without alt=""

    Form labels:

    • Find all inputs
    • Check for associated labels
    • Verify aria-label or aria-labelledby

    Keyboard navigation:

    • Check for onClick on non-interactive elements
    • Verify tabIndex usage
    • Check for keyboard event handlers

    Color contrast:

    • Identify text and background colors
    • Calculate contrast ratios
    • Flag ratios below 4.5:1 (AA)

    Heading hierarchy:

    • Check heading levels (h1-h6)
    • Verify no skipped levels
    • Ensure single h1 per page
  3. Check ARIA usage:

    • Verify valid ARIA attributes
    • Check for redundant ARIA
    • Validate ARIA roles
  4. Provide severity ratings:

    Critical (must fix):

    • Missing alt text on images
    • Form inputs without labels
    • Keyboard traps
    • Color contrast below 3:1

    High (should fix):

    • Color contrast below 4.5:1
    • Missing ARIA labels on icon buttons
    • Improper heading hierarchy
    • Missing skip links

    Medium (recommended):

    • Missing lang attribute
    • No focus indicators
    • Redundant ARIA
    • Missing landmarks
  5. Provide remediation code:

    For each issue, show before/after:

    // Before
    <img src="logo.png" />
    
    // After
    <img src="logo.png" alt="Company Logo" />
    
  6. Generate accessibility report:

    Accessibility Audit Report
    ==========================

    Critical Issues (3):
    1. Missing alt text on 5 images
    2. Form input without label (email field)
    3. Button not keyboard accessible
    
    High Priority (4):
    1. Color contrast 3.2:1 on button (needs 4.5:1)
    2. Heading hierarchy skips from h1 to h3
    3. Icon button missing aria-label
    4. No skip link for keyboard users
    
    Medium Priority (2):
    1. Missing lang attribute on html
    2. Focus indicator not visible
    
    Compliance Score: 65/100
    Estimated fix time: 2-3 hours
