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.

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 | $0.00158 | $0.02551 |
| Opus 5 | $0.00079 | $0.01275 |
| Sonnet 5 | $0.00032 | $0.00510 |
| Haiku 4.5 | $0.00016 | $0.00255 |
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 12d 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 — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Accessibility Audit
Accessibility is not a feature for a minority. Temporary and situational impairments — a broken arm, bright sunlight, a noisy room, a trackpad that stopped working — mean everyone uses accessible design eventually. It is also increasingly a legal requirement rather than a nice-to-have.
Automated tools catch roughly a third of WCAG issues. They are necessary and nowhere near sufficient. The findings that matter come from the manual pass.
The four-test triage — run this first
Ten minutes, and it finds most serious problems.
1. Unplug the mouse
Complete the critical journey with Tab, Shift+Tab, Enter, Space and the
arrow keys.
- Can you reach every interactive element?
- Can you see where you are at all times? (A visible focus indicator is not
optional —
outline: nonewith no replacement is aP1on its own.) - Does the focus order follow the visual order?
- Can you escape every component — modal, menu, date picker — without a mouse?
- Does anything trap focus permanently?
- Is there a skip link to bypass the navigation?
2. Zoom to 400%
At 400% zoom on a 1280px viewport (equivalent to a 320px-wide window):
- Does all content remain available?
- Is there horizontal scrolling? (Reflow failure.)
- Do fixed elements cover the content?
- Does text truncate or overlap?
3. Turn on a screen reader
NVDA (Windows, free), VoiceOver (macOS/iOS, built in), TalkBack (Android).
Twenty minutes learning the basic commands pays for itself permanently, because it converts "I think this is accessible" into evidence.
- Is the page structure announced (headings, landmarks, lists)?
- Does every control announce a meaningful name and its role?
- Are state changes announced (loading, error, success, expanded)?
- Do images announce useful alt text — or a filename?
4. Run the automated scanner
axe DevTools, Lighthouse, or WAVE. Fix what it finds, then remember it found a third of the problems. A clean automated scan is a starting line, not a finish.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

accessibility-audit is a skill published in the GitHub repository Kin9Zeus/senior-engineer-skills (3 stars, last pushed 18d ago), licensed MIT. It adds 158 tokens to every session and 2,551 once invoked, about $0.0008 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 2026-08-31.

Audit and improve web accessibility following WCAG 2.2 guidelines. Use when asked to "improve accessibility", "a11y audit", "WCAG compliance", "screen reader support", "keyboard navigation", or "make accessible".
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…
data-display-and-selection
Complex data deserves multiple view modes — grid, list, table — chosen by the user based on their task. Row and item selection should use large hit areas (the whole row or card, not just a checkbox). Selected state is communicated through a subtle background colour shift. Mass actions appear when items are selected.…
generate-ui-from-brand
Pipeline skill — turns a URL or DESIGN.md into a concrete UI structure with decisions already made. Extracts live design tokens, normalizes them into a semantic system, applies UX principles, and outputs an actionable UI spec. Use when building UI for an existing brand from scratch, auditing a design system, or…
information-architecture
In large applications, information architecture determines whether users can find, understand, and act on data. Naming matters. The UI should mirror the data model and signal how data can be transformed. Dangerous or irreversible changes always require a confirm dialog. Use when designing navigation, naming entities…
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…
