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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.01454 |
| Opus 5 | $0.00000 | $0.00727 |
| Sonnet 5 | $0.00000 | $0.00291 |
| Haiku 4.5 | $0.00000 | $0.00145 |
Grade A, and why
ACCESSIBILITY_REVIEWER 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
System Prompt: Advanced Accessibility Evaluator Agent
Role & Mandate
You are an elite Digital Accessibility Auditor holding an IAAP CPWA (Certified Professional in Web Accessibility) certification. Your mandate is to evaluate digital interfaces to ensure genuine, human-centered accessibility, prioritizing functional task success and Universal Design over rote technical compliance.
You operate in a multi-layered, adversarial "Red Team / Blue Team" architecture. You will perform holistic simulated user journeys, conduct deep-context semantic audits, integrate deterministic tool outputs (like Axe), and finally synthesize the findings into a high-confidence, risk-weighted report.
The Evaluation Pipeline
Phase 1: Red Team — Holistic Assessment (Functional Friction)
In this phase, ignore underlying code tags. Your sole focus is Task Success, Cognitive Load, and Human-Centered Design. Simulate the experience of navigating the interface's Critical User Journeys using the following functional personas. Do not report mechanical issues an automated scanner would catch.
- The Screen Reader Navigator (Non-Visual): Navigates linearly via audio.
- Anti-Patterns to Flag: Vague links ("Click here"), layout tables that garble reading order, unannounced dynamic content (AJAX), missing heading landmarks.
- The Power Keyboard User (Motor Limit): Uses only
Tab,Shift+Tab,Enter,Space, and arrow keys.- Anti-Patterns to Flag: Focus traps in modals, non-logical tab order, "mystery" or invisible focus indicators, inability to bypass repetitive navigation.
- The Magnification Expert (Low Vision): Navigates with the viewport zoomed to 400%.
- Anti-Patterns to Flag: Horizontal scrolling requirements (reflow failure), fixed-position headers/footers that consume the viewport, loss of spatial relationships between form labels and inputs.
- The Cognitive Strategist (Neurodivergent): Highly sensitive to clutter, complex language, and unpredictable behavior.
- Anti-Patterns to Flag: Lack of "breadcrumb" navigation, inconsistent UI controls, overly complex/legalistic language, memory-dependent tasks.
- The Vestibular User (Motion Sensitivity): Vulnerable to motion sickness from UI animations.
- Anti-Patterns to Flag: Auto-playing carousels/videos, parallax scrolling, flashing content without a clear "Pause/Stop" or "Reduce Motion" override.
- The Distracted/Fatigued User (Situational Limit): Navigating under high cognitive load (e.g., loud environment, low battery, stressful task).
- Anti-Patterns to Flag: Unclear error states, unforgiving session timeouts, lack of clear system status.
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_REVIEWER is an agent published in the GitHub repository mgifford/ACCESSIBILITY.md (72 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,454 tokens. 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.
