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 | $0.00068 | $0.03239 |
| Opus 5.5 | $0.00027 | $0.01296 |
| Sonnet 5.5 | $0.00014 | $0.00648 |
| Haiku 4.5 | $0.00007 | $0.00324 |
Grade A, and why
kb-cognitive-accessibility 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 1mo 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.

Skill: Cognitive Accessibility
Domain: Cognitive, learning, and neurological accessibility
WCAG scope: WCAG 2.2 AA + key AAA, COGA W3C guidance
Agents that use this skill: cognitive-accessibility, web-accessibility-wizard, accessibility-lead, forms-specialist
Purpose
This skill provides reference tables, scoring formulas, and evaluation patterns for cognitive accessibility review. It covers:
- WCAG 2.2 success criteria with cognitive accessibility relevance
- COGA (Cognitive Accessibility) W3C guidance mapping
- Plain language analysis techniques
- Reading level computation
- Authentication pattern analysis (3.3.8 / 3.3.9)
- Redundant entry detection (3.3.7)
- Timeout and session management analysis
WCAG 2.2 Cognitive Accessibility Criteria Reference
Level A
Each SC, with name, what to check and common failures.
| SC | Name | What to Check | Common Failures |
|---|---|---|---|
| 2.2.1 | Timing Adjustable | Session timeouts warn >=20s before expiry; user can extend >=10x or disable | Redirect without warning; extension UI exists but does nothing |
| 2.2.2 | Pause, Stop, Hide | Auto-moving/blinking content >5s has pause/stop control | Blinking backgrounds, marquee text, auto-scrolling feeds |
| 2.3.1 | Three Flashes | No content flashes >3 Hz (absolute) | Transition animations that strobe |
| 3.3.1 | Error Identification | Error identified in text, not just color | Red border with no error message |
| 3.3.2 | Labels or Instructions | Format requirements shown before error, required fields identified upfront | Format hint only in error state; asterisks with no legend |
| 3.3.7 | Redundant Entry (2.2 new) | Previously-entered info not re-requested in same session unless security-essential or stale | Email re-entered on step 3; billing address not pre-filled from shipping |
Level AA
Each SC, with name, what to check and common failures.
| SC | Name | What to Check | Common Failures |
|---|---|---|---|
| 2.4.6 | Headings and Labels | Headings describe content; labels describe input purpose | "Section 1", "Info", "Details" as heading text |
| 3.2.3 | Consistent Navigation | Nav appears in same relative order across pages | Footer nav changes order on mobile vs desktop |
| 3.2.4 | Consistent Identification | Same-function components have same accessible name across pages | "Search" button on one page, "Find" on another |
| 3.3.3 | Error Suggestion | For detected errors, suggest correction when possible/safe | "Invalid email" with no example or format hint |
| 3.3.4 | Error Prevention (Legal, Financial) | Review step before irreversible submission; allow reversal or confirmation | One-click purchase with no review screen; no undo for account deletion |
| 3.3.8 | Accessible Authentication Min. (2.2 new) | Authentication must not require cognitive function test unless an alternative exists | autocomplete="off" on login forms; paste disabled in password fields; transcription-only CAPTCHA |
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.

kb-cognitive-accessibility is a skill published in the GitHub repository Community-Access/accessibility-agents (428 stars, last pushed 1mo ago), licensed MIT. It adds 68 tokens to every session and 3,239 once invoked, about $0.0003 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 2026-09-23.
