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 | $0.00107 | $0.01658 |
| Opus 5 | $0.00053 | $0.00829 |
| Sonnet 5 | $0.00021 | $0.00332 |
| Haiku 4.5 | $0.00011 | $0.00166 |
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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Accessibility audit
Evaluate a design, page, or component against WCAG 2.2 Level AA and produce a severity-scored report with a remediation for every finding. This skill diagnoses and grades; when a fix means writing code, hand off to the accessible-components skill.
When to use
Use when the user asks to "audit accessibility", "check a11y", run a "WCAG audit", "check color contrast", confirm "is this accessible", or do an "accessibility review before handoff". Also use proactively before a design ships to engineering.
Inputs
Work from whatever is available, and say which mode you used:
- Source code (HTML/JSX/Vue/etc.) — inspect markup, roles, attributes, and styles directly. Most thorough.
- A screenshot — assess visual checks (contrast, target size, focus indication if captured, text legibility); flag what cannot be verified visually (keyboard, names, sequence) as "needs manual test".
- A description — reason about likely issues and list the manual checks the user must run.
- A live URL or local HTML file — run automated checks (see below) AND the manual walkthrough.
Method: POUR
Walk the four WCAG principles in order. The full per-criterion checklist with criterion numbers and test steps is in references/wcag-2.2-aa-checklist.md — load it and work through it.
- Perceivable — text alternatives (1.1.1), captions/audio (1.2.x), info-and-relationships and meaningful sequence (1.3.1, 1.3.2), use of color not alone (1.4.1), contrast (1.4.3 text, 1.4.11 non-text), resize/reflow/text-spacing (1.4.4, 1.4.10, 1.4.12), content on hover/focus (1.4.13).
- Operable — keyboard (2.1.1) and no trap (2.1.2), enough time (2.2.x), no flashing (2.3.1), bypass blocks / headings / focus order / link purpose / multiple ways (2.4.x), focus not obscured (2.4.11), focus appearance, pointer gestures and dragging movements (2.5.7), target size 24px minimum (2.5.8).
- Understandable — language (3.1.x), on-focus/on-input no surprise (3.2.x), consistent help (3.2.6), error identification/labels/suggestions (3.3.1–3.3.4), redundant entry (3.3.7), accessible authentication (3.3.8).
- Robust — valid parsing, name/role/value (4.1.2), status messages (4.1.3).
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 TimboGP/timbogp-marketplace (3 stars, last pushed 2mo ago), licensed MIT. It adds 107 tokens to every session and 1,658 once invoked, about $0.0005 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.
