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 | $0.00081 | $0.00793 |
| Opus 5 | $0.00041 | $0.00396 |
| Sonnet 5 | $0.00016 | $0.00159 |
| Haiku 4.5 | $0.00008 | $0.00079 |
Grade A, and why
ability-spectrum-mapping 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ability Spectrum Mapping
Map how a feature performs across the full range of human ability — from full capability to no capability in each dimension — to identify where the design starts to break down and who gets excluded.
Why a Spectrum
Accessibility is not binary. It's not "can see" vs "blind." The reality is a continuous spectrum:
- Full vision → needs glasses → low vision → legally blind → no vision
- Full hearing → mild loss → moderate loss → severe loss → deaf
- Full dexterity → mild tremor → limited range → single hand → no hands
- Full cognition → mild difficulty → moderate difficulty → significant support needs
Products don't go from "works" to "doesn't work" in a single step. They degrade gradually. The spectrum map shows you exactly where your design starts failing and for whom.
How to Build an Ability Spectrum Map
Step 1: List Core Tasks
Identify the 5–10 most important tasks a user performs with the product.
Step 2: Define the Spectrums
For each relevant ability dimension, define 4–5 points:
Vision spectrum: Full vision → Corrected vision → Low vision (magnification) → Very low vision (screen reader + some vision) → No vision (screen reader only)
Hearing spectrum: Full hearing → Mild loss (louder volume) → Moderate loss (captions needed) → Severe loss (captions + visual alerts) → Deaf (fully visual communication)
Motor spectrum: Full dexterity → Reduced precision (larger targets) → Limited range (keyboard only) → Minimal movement (switch or voice) → No hand use (eye tracking, sip-and-puff)
Cognitive spectrum: Comfortable with complexity → Prefers simplicity → Needs plain language → Needs step-by-step guidance → Needs significant support
Step 3: Map Each Task
For each task × ability point, rate:
- Works well — no barriers
- Works with friction — possible but harder than it should be
- Works with workaround — user must find their own solution
- Fails — task cannot be completed
Step 4: Identify the Breakpoints
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.

ability-spectrum-mapping is a skill published in the GitHub repository Owl-Listener/inclusive-design-skills (98 stars, last pushed 3mo ago), licensed MIT. It adds 81 tokens to every session and 793 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.
