 # InternalAI Workspace
 
-Agent-assisted workspace for analyzing and tracking Monadical's internal data: meetings, emails, Zulip conversations, calendar events, documents, and git activity.
+Agent-assisted workspace to work on your own data with InternalAI (ContactDB / DataIndex).
+
+## Setup
+
+### Prerequisites
+
+- [Greywall](https://gitea.app.monadical.io/monadical/greywall) installed — verify with `greywall --version`
+- [OpenCode](https://opencode.ai) installed as a native binary (not a wrapper via bun/npm/pnpm)
+
+### Greywall sandbox template
+
+Run OpenCode in learning mode so Greywall can observe which files it reads and writes:
+
+```
+greywall --learning -- opencode
+```
+
+Interact briefly, then exit OpenCode. Greywall generates a sandbox template based on the observed filesystem access. Edit the template if needed.
+
+### MCP configuration
+
+Add the ContactDB and DataIndex MCP servers:
+
+```
+greywall -- opencode mcp add
+```
+
+Run the command twice with these settings:
+
+| Name | Type | URL | OAuth |
+|------|------|-----|-------|
+| `contactdb` | Remote MCP | `http://caddy/contactdb-api/mcp/` | No |
+| `dataindex` | Remote MCP | `http://caddy/dataindex/mcp/` | No |
+
+Verify the servers are registered:
+
+```
+greywall -- opencode mcp list
+```
+
+Then open your proxy at `http://localhost:42000/proxy` and allow access to Caddy.
+
+### LiteLLM provider
+
+Add a `litellm` provider in `opencode.json`:
+
+```json
+{
+  "$schema": "https://opencode.ai/config.json",
+  "provider": {
+    "litellm": {
+      "npm": "@ai-sdk/openai-compatible",
+      "name": "Litellm",
+      "options": {
+        "baseURL": "https://litellm-notrack.app.monadical.io",
+        "apiKey": "sk-xxxxx"
+      },
+      "models": {
+        "Kimi-K2.5-sandbox": {
+          "name": "Kimi-K2.5-sandbox"
+        }
+      }
+    }
+  }
+}
+```
+
+Replace `apiKey` with your own key (check 1Password for "litellm notrack").
+
+## Usage
+
+Start OpenCode inside the Greywall sandbox:
+
+```
+greywall -- opencode
+```
+
+### First-run checklist
+
+1. Select the Kimi K2.5 model under litellm in `/models` — type "hello" to confirm it responds (if not, check the proxy)
+2. Test ContactDB access — ask "who am I?" (should trigger `get_me`)
+3. Test DataIndex access — ask "what was my last meeting about?"
+
+### Things you can do
+
+- **Onboard yourself** — `can you onboard me?` creates your `MYSELF.md`
+- **Weekly checkout** — `create my checkout of last week` builds a summary from your activity
+- **Data analysis** — `create a workflow that searches all meetings since 2024 where Max is listed as a participant (not a contactdb), and output as csv` creates a marimo notebook in `workflows/`
+- **Init a project** — `create the creatrix project` creates `projects/creatrix/` with base information
+- **Sync a project** — `sync the creatrix project` runs a full 1-year analysis on the first run, then incremental syncs afterward, producing a live `project.md` document
