トースト（通知）を出す
$.ui.toast(text) は、会話の右上に mod の名前付きの短い知らせを出し、数秒（既定 4 秒、{ timeoutMs } で変更）で消えます。ターンを始めないので、作業の終わりや失敗を知らせるのに向きます。
$.ui.toast(text, { timeoutMs })$.ui.log(text)
最小の形
hooks/register.js
export function register(on) {
on('tool.call', { tool: ['Edit', 'Write'] }, async ($, e, next) => {
const result = await next(e)
if (!result.deny && !result.isError) $.ui.toast('Saved ' + e.file_path, { timeoutMs: 3000 })
return result
})
}
modscode が公式ドキュメントの API で書いた最小の例です。自由に使えます。
