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 | $0.00052 | $0.01984 |
| Opus 5 | $0.00026 | $0.00992 |
| Sonnet 5 | $0.00010 | $0.00397 |
| Haiku 4.5 | $0.00005 | $0.00198 |
Grade A, and why
age-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 10d 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.

Age-Inclusive Design
Purpose
This skill helps create digital experiences that work well for users of all ages. It addresses age-related changes in vision, motor control, cognition, and technology comfort to reduce friction and improve accessibility for older and younger users alike. Based on ISO 25556:2025 (Ageing-inclusive digital economy) and NIST usability guidelines.
When to Use
Use this skill when:
- Designing for older adults (65+)
- Creating multi-generational products
- Improving accessibility for elderly users
- Reducing age-related friction in interfaces
- Making content accessible across age groups
- Addressing usability concerns for seniors
Age-Related Changes to Consider
Vision Changes
- Reduced visual acuity
- Need for larger text
- Reduced contrast sensitivity
- Difficulty focusing on close objects
- Increased sensitivity to glare
- Changes in color perception
Motor Changes
- Reduced fine motor control
- Tremors or shaky hands
- Reduced grip strength
- Slower response times
- Difficulty with precise movements
Cognitive Changes
- Slower processing speed
- Reduced working memory
- Difficulty with new interfaces
- May prefer familiar patterns
- May need more time for decisions
Technology Comfort
- May be less familiar with technology
- May lack confidence with new interfaces
- May prefer step-by-step guidance
- May be wary of online security
Boundaries
Always
- Use minimum 16px font for body text
- Ensure 4.5:1 contrast ratio (WCAG AA)
- Make click/touch targets minimum 44x44px
- Provide clear, immediate feedback
- Use simple, familiar language
- Offer customization options
Ask First
- Ask about preferred font sizes
- Confirm before auto-completing actions
- Ask about preferred level of assistance
Never
- Never assume all older adults are the same
- Never use age stereotypes (e.g., "elderly don't use tech")
- Never make interactions time-sensitive without warning
- Never hide important information in small text
- Never assume low tech literacy (many seniors are tech-savvy)

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.

age-inclusive-design is a skill published in the GitHub repository humanity4ai/project_human (4 stars, last pushed 5d ago), licensed MIT. It adds 52 tokens to every session and 1,984 once invoked, about $0.0003 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.
