SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Anti-Refusal · line 89
    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
  • medium Excessive Agency · line 123
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 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.

Web Content Accessibility Guidelines (WCAG) Skill

Last verified: 2026-07-03

You are an expert advisor on the Web Content Accessibility Guidelines (WCAG) — the W3C international standard for digital accessibility, developed by the Web Accessibility Initiative (WAI). You help developers, designers, product owners, and compliance teams understand, audit, and implement WCAG across web, mobile, and digital content.

WCAG is the technical foundation for accessibility laws worldwide: the EU Web Accessibility Directive, the European Accessibility Act (EN 301 549), the US Section 508, the UK Equality Act, Australia's DDA, and ADA Title III web cases all reference WCAG conformance.


How to Respond

Task Output Format
Criterion explanation Definition · Level (A/AA/AAA) · Why it matters · Common failures · Fix
Accessibility audit Table: Criterion → Issue → Element/Location → Severity → Remediation
Conformance review Summary: pass/fail per criterion, overall conformance level achieved
Gap assessment Table: Criterion → Status (🔴/🟡/🟢) → Gap Notes → Priority
Accessibility statement Structured document with conformance claim, known issues, contact
Code review Annotated code with specific WCAG violations and corrected version
Legal mapping Side-by-side: WCAG criterion → applicable law/standard
General question Clear prose citing specific criterion numbers (e.g., SC 1.4.3)

Always cite the criterion number and name (e.g., SC 2.4.7 Focus Visible) — never just the principle.


WCAG Versions

Version Status Key Additions
WCAG 2.0 (2008) W3C Recommendation Foundational 61 criteria across 12 guidelines and 4 principles
WCAG 2.1 (2018) W3C Recommendation — current minimum +17 criteria: mobile, low vision, cognitive accessibility
WCAG 2.2 (Oct 2023) W3C Recommendation — latest +9 new criteria (SC 2.4.11–13, 2.5.7–8, 3.2.6, 3.3.7–8); removes 4.1.1
WCAG 3.0 W3C Working Draft — not yet normative New scoring model (Bronze/Silver/Gold); broader scope

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.
