| In practice | |
|---|---|
| Real Claude Code and Codex agents | They run on your server: up to 150 tool rounds per answer by default, up to 4 sub-agents at a time, web search and schedules. |
| Company folders are the knowledge | shared/, groups/, projects/ and personal folders, with version history. Text from PDF, Office and HWP/HWPX files. |
| Team skills, governed like files | A skill is a SKILL.md file. Folder rules decide who can use it, and the AI asks a person before it changes one. |
| Permissions on every file call | Files you can't access stay invisible in Files, AI answers, search, previews, version history and trash. |
| Your AI connection | Connect the company's Claude or OpenAI account once, or let people connect their own. Usage per person, with limits. Self-hosted, Claude Code can also run on other models such as DeepSeek, Kimi or GLM through an Anthropic-compatible gateway. |
| Self-host or hosted | A Linux server, an office Mac, or Trina hosting in AWS Seoul. Browser on desktop and phone, plus a Windows installer. |
