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 | $0.00114 | $0.02105 |
| Opus 5.5 | $0.00046 | $0.00842 |
| Sonnet 5.5 | $0.00023 | $0.00421 |
| Haiku 4.5 | $0.00011 | $0.00211 |
Grade A, and why
accessibility-inclusive-design 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 5d 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Accessibility Is Not a Feature -- It Is a Design Quality Indicator
16% of the global population has a disability (WHO). Accessibility is not an edge case -- it is a core design quality dimension. WCAG 2.2 AA compliance is the minimum bar, not a stretch goal. Inaccessible design is broken design.
WCAG 2.2 POUR Principles
| Principle | Requirement | Key Rules |
|---|---|---|
| Perceivable | All content perceivable by all users | Text alternatives, captions, sufficient contrast, no color-only meaning |
| Operable | All functionality operable via all input methods | Keyboard accessible, no time traps, skip links, focus indicators |
| Understandable | Content and operation are understandable | Plain language, consistent navigation, specific error messages |
| Robust | Content works with current and future technologies | Valid HTML, ARIA roles used correctly, tested across assistive tech |
Contrast Requirements
| Element | Minimum Ratio (AA) | AAA Target | Tool |
|---|---|---|---|
| Body text (<18px / <14px bold) | 4.5:1 | 7:1 | WebAIM Contrast Checker |
| Large text (>=18px / >=14px bold) | 3:1 | 4.5:1 | Chrome DevTools |
| Non-text elements (icons, borders, focus rings) | 3:1 | -- | axe-core |
| Disabled elements | Exempt | -- | -- |
| Decorative elements | Exempt | -- | -- |
Practical rule: Test every foreground/background combination. Gray text on white is the most common failure -- #767676 on #fff is the lightest gray that passes 4.5:1.
Color Independence
Never rely on color alone to convey meaning. Provide redundant encoding for every color-coded element.
| Context | Bad (Color Only) | Good (Redundant Encoding) |
|---|---|---|
| Status indicators | Red dot / green dot | Red dot + "Error" label / green dot + checkmark icon |
| Form validation | Red border on invalid field | Red border + error icon + error message text |
| Charts and data viz | Color-coded lines only | Color + pattern (dash, dot) + labeled legend |
| Links in body text | Color difference only | Color + underline (or underline on hover minimum) |
| Alerts and banners | Background color only | Background color + icon + role="alert" |
What ships with it
1 file 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-inclusive-design is a skill published in the GitHub repository oborchers/fractional-cto (32 stars, last pushed 5d ago), licensed MIT. It adds 114 tokens to every session and 2,105 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-10-13.
