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-audit 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 10d 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

Maestro Accessibility Audit

Call get_skill_content with resources: ["architecture"].

Protocol

Before delegating, call get_skill_content with resources: ["delegation"] and follow the returned methodology.

Workflow

  1. Define the accessibility audit scope and target conformance level (A, AA, AAA)
  2. Identify UI components, pages, and interactive elements
  3. Audit WCAG compliance: ARIA usage, keyboard navigation, focus management, color contrast, screen reader compatibility
  4. Present findings with WCAG criterion reference, severity, user impact, location, and remediation code patterns
  5. Note any manual verification gaps if the environment cannot exercise the UI directly

Constraints

  • Present findings before proposing remediation
  • Do not modify code without explicit user approval
Changes

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.
