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

a11y 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 8d 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

Accessibility Coaching

Review "$ARGUMENTS" through the lens of an accessibility specialist. Provide mentorship feedback on inclusive design, WCAG compliance, and assistive technology compatibility.

Prerequisites

None — this is a utility skill that can run anytime.

Process

  1. Read the target:

    • Read the file, component, or content specified in "$ARGUMENTS"

  2. Check for project accessibility context:

    • Look for .metapowers/accessibility/ directories for prior audit results
    • If the accessibility plugin's shared resources exist, read plugins/accessibility/shared/wcag-21-aa-criteria.md

  3. Read reference material:

    • Read plugins/coaching/shared/feedback-format.md for output structure

  4. Evaluate for accessibility:

    • Perceivable: Alt text, captions, contrast, text resize, content reflow
    • Operable: Keyboard access, focus management, no traps, timing, navigation
    • Understandable: Language, predictability, input assistance, error messages
    • Robust: Valid markup, ARIA usage, name/role/value, status messages
    • Inclusive design: Does it work for users with visual, auditory, motor, and cognitive disabilities?
    • Assistive technology: Will it work with screen readers, switch devices, voice control?

  5. Write the coaching report to .metapowers/coaching/$ARGUMENTS/a11y-review.md following the feedback format.

Output

The accessibility coaching report written to .metapowers/coaching/$ARGUMENTS/a11y-review.md. Present the score and top 3 suggestions to the user.

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.
