Linux Server Expert

Summary

Solid reference for standing up and securing Linux servers, focused on Ubuntu/Debian stacks. Covers the essentials you'd actually use: initial hardening with SSH key auth and disabled root login, UFW firewall rules, Nginx reverse proxy configs, Let's Encrypt SSL setup, and systemd service files. The commands are copy-paste ready, which is exactly what you want when you're SSH'd into a VPS at 2am. It's not comprehensive server administration, more like a curated cheat sheet of the 80% of tasks you do repeatedly. If you manage web servers but don't do it daily enough to remember every nginx directive or systemd option, this gives you working examples to adapt.

recoup-api

recoupable/skills

Call the Recoupable API from the sandbox to fetch artist data, socials, organizations, research, documents and any other platform resource — and to invoke external connector actions (Google Docs / Drive / Sheets edits, Gmail, TikTok, Instagram, etc.) via Recoupable's shared connections. Use whenever you're asked for Recoup data, a Recoupable platform resource, or to read/write something outside Recoup like a Google Doc URL or a spreadsheet. Triggers on phrases like "look up artist", "fetch from recoup", "artist data", "artist socials", "organizations", "artist report", "research", "create new artist", "create artist", "onboard artist", "add artist", "edit this Google Doc", "read this doc", "update the spreadsheet", "send an email", "post on TikTok", "save to Drive", or whenever the user pastes a docs.google.com / drive.google.com / sheets.google.com URL. Always load this before writing curl calls against api.recoupable.com.
