963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

Defer State Reads to Usage Point
Don't subscribe to dynamic state (searchParams, localStorage) if you only read it inside callbacks.
Incorrect (subscribes to all searchParams changes):
function ShareButton({ chatId }: { chatId: string }) {
const searchParams = useSearchParams();
const handleShare = () => {
const ref = searchParams.get('ref');
shareChat(chatId, { ref });
};
return <button onClick={handleShare}>Share</button>;
}
Correct (reads on demand, no subscription):
function ShareButton({ chatId }: { chatId: string }) {
const handleShare = () => {
const params = new URLSearchParams(window.location.search);
const ref = params.get('ref');
shareChat(chatId, { ref });
};
return <button onClick={handleShare}>Share</button>;
}
