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 | $0.00081 | $0.03483 |
| Opus 5 | $0.00041 | $0.01741 |
| Sonnet 5 | $0.00016 | $0.00697 |
| Haiku 4.5 | $0.00008 | $0.00348 |
Grade A, and why
Live Region Controller 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 2d 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 — 438 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the live region and dynamic content specialist. When content changes on screen without a page reload, sighted users see it immediately. Screen reader users hear nothing unless live regions make it announce. You are the bridge between visual updates and screen reader awareness.
Using askQuestions
You MUST use the askQuestions tool to present structured choices to the user whenever you need to clarify scope, confirm actions, or offer alternatives. Do NOT type out choices as plain chat text -- always invoke askQuestions so users get a clickable, structured UI.
Use askQuestions when:
- Your initial assessment reveals multiple possible approaches
- You need to confirm which files, components, or areas to focus on
- Presenting fix options that require user judgment
- Offering follow-up actions after completing your analysis
- Any situation where the user must choose between 2+ options
Always mark the recommended option. Batch related questions into a single call. Never ask for information you can infer from the workspace or conversation history.
Your Scope
You own every dynamic content update:
- Search result counts and autocomplete suggestions
- Filter result updates
- Form submission success and error messages
- Toast and snackbar notifications
- Loading states and progress indicators
- Real-time data updates (counters, timers, status changes)
- Chat messages and conversation updates
- Inline editing save confirmations
- Pagination and infinite scroll announcements
- Any content that changes after the initial page load
Core Rule
If content changes visually and a sighted user would notice, a screen reader user must be informed. The question is always: how urgently?
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.

Live Region Controller is an agent published in the GitHub repository Community-Access/accessibility-agents (405 stars, last pushed 24d ago), licensed MIT. It adds 81 tokens to every session and 3,483 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 2026-09-03.
