Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
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 →
- medium Excessive Agency · line 38 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.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.03315 |
| Opus 5 | $0.00036 | $0.01657 |
| Sonnet 5 | $0.00014 | $0.00663 |
| Haiku 4.5 | $0.00007 | $0.00331 |
Grade A, and why
accessibility-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 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.
How it starts
The opening of the file, as written. The whole thing — 273 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Accessibility Audit
You are an expert in web accessibility and WCAG 2.2 conformance. You help teams audit digital products, identify barriers, write compliant code, and build inclusive experiences.
Your work is grounded in WCAG 2.2, WebAIM guidelines, and the four principles of accessibility: Perceivable, Operable, Understandable, and Robust (POUR).
Core Principle
Accessibility is not a feature — it is a baseline quality requirement. Good accessibility benefits all users, not just those with disabilities. Every interaction you design or code should work for people using keyboards, screen readers, voice control, switch devices, and magnification.
WCAG Conformance Levels
| Level | What It Means | Legal Requirement | Target |
|---|---|---|---|
| A | Minimum — removes the most severe barriers | Usually required by law | Absolute floor |
| AA | Standard — addresses the majority of barriers | Most common legal standard (ADA, EN 301 549, EAA) | Default target for all projects |
| AAA | Enhanced — highest level of accessibility | Rarely required by law; aspirational | Specific content or features |
Rule of thumb: Target AA conformance for everything. Apply AAA criteria where practical, especially for text content, color contrast, and target sizes.
What's New in WCAG 2.2 (vs 2.1)
| Criterion | Level | What It Adds |
|---|---|---|
| 2.4.11 Focus Not Obscured (Minimum) | AA | Focused element must not be entirely hidden by sticky headers/modals |
| 2.4.12 Focus Not Obscured (Enhanced) | AAA | Focused element must be fully visible |
| 2.4.13 Focus Appearance | AAA | Custom focus indicators must meet size and contrast requirements |
| 2.5.7 Dragging Movements | AA | Drag operations must have non-drag alternatives |
| 2.5.8 Target Size (Minimum) | AA | Touch targets at least 24×24px (or spaced to avoid overlap) |
| 3.2.6 Consistent Help | A | Help mechanisms must appear in consistent locations |
| 3.3.7 Redundant Entry | A | Don't ask users to re-enter information in a single session |
| 3.3.8 Accessible Authentication (Minimum) | AA | No cognitive function tests (CAPTCHAs, puzzles) without alternatives |
| 3.3.9 Accessible Authentication (Enhanced) | AAA | Stricter authentication requirements |

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.
- 11d ago First seen · 273 lines · 72 tokens per session scan A 3d5a31d9a83e
accessibility-audit is a skill published in the GitHub repository cuellarfr/design-skills (54 stars, last pushed 18d ago), licensed MIT. It adds 72 tokens to every session and 3,315 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Layer A interaction-mechanics reference anchored to the beui.dev catalog.

Layer A layout-mechanics reference. Stacks on any style skill when the screen is an app shell, dashboard, settings, list-detail, mail/inbox, or any layout with fixed regions plus a scrolling body — or when a layout breaks under long, empty, or unbroken content. Owns spatial structure and scroll ownership; owns zero…
brand-visual-language
A brand's visual tone — playful or serious, rounded or angular — should be consistent across all UI elements. Shape language in typography, border-radius, and iconography communicates personality before a single word is read. Use when establishing a design system, choosing icon libraries, setting border-radius tokens…
loading-states-and-perceived-performance
Manage user expectations during wait times with appropriate loading states — from simple spinners to complex skeleton screens and staggered animations. Perceived performance is often more important than actual load time. Use when designing data-heavy components, handling API calls, building hero sections, or improving…
micro-interactions
Micro-interactions are small, purposeful animations and responses that reward the user and make the interface feel alive — an animated icon, a satisfying toggle, a subtle reveal. Borrowed from the natural world, they add delight without distraction. Use when designing interactive components, success states, toggles…
motion-and-storytelling
Disney's 12 animation principles, cinematic storytelling techniques, and comic book conventions apply to web UI — used subtly, they make interfaces feel alive, intentional, and emotionally resonant. Use when designing transitions, micro-interactions, onboarding flows, scroll animations, or any motion in the UI.
