Agent Skills: manage-apps-and-sounds-headless

Control the pushover.net web dashboard headlessly for things the HTTP API cannot do - log in, list applications, CREATE or DELETE Pushover applications (returning the new app's API token), and ADD or REMOVE custom notification sounds (with a sourcing+loudness pipeline for free MP3 jingles). Drives Playwright's Google Chrome for Testing (never your own Google Chrome unless asked with --browser chrome). Use when the user wants to automate the Pushover website/dashboard rather than send notifications (that is send-notification). TRIGGERS - pushover dashboard, create pushover app, delete pushover app, new api token, add custom sound, upload pushover sound, remove custom sound, find jingle, pushover web automation.
