97 seconds, sound on. A team lead sets up Claude once, and on her first day a new hire’s proposal comes out like his. Animated story with the real app at 1:15. Fictional company.
## Same request, two answers
Claude Code in an empty folder It can't know your company, so it asks six questions first.
Trina AX, same line It starts from the team's files and the CEO's proposal skill.
Real outputs from 2026-10-31 and 11-01 with a fictional company, Dawnroute; the deck photos were made with Higgsfield. Claude Code is right to ask: nothing in an empty folder tells it who you are. Trina gives it the folder.
## How it works
1. Put it in once. Company files go in shared/. The way you write a proposal goes in skills/proposal/SKILL.md.
2. Everyone asks. In a chat app in the browser, on desktop or phone. No terminal, nothing to install on their laptop.
3. Each person keeps their own access. The server checks every file the AI opens, as the person asking. A folder you can't see doesn't exist for your AI either.
Same question, different people. Mina is in Sales. The revenue file sits in shared/Finance , which she can't open, so her AI can't open it either.

## What you get
| | 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. |
