# omm-view — Architecture Viewer
## Purpose
Launch the interactive web viewer so the user can explore `.omm/` architecture diagrams in their browser.
## Prerequisites
Ensure the `omm` CLI is available:
```bash
command -v omm || npm install -g oh-my-mermaid
```
If the install command fails (permission denied), tell the user:
"Please run `npm install -g oh-my-mermaid` in your terminal, then try again."
## Steps
### Step 1: Verify .omm/ exists
```bash
omm list
```
If no classes found, tell the user:
"No architecture docs found. Run `/omm-scan` first to generate them."
Then stop.
### Step 2: Start the viewer
```bash
omm view
```
If the user specified a port:
```bash
omm view --port <port>
```
### Step 3: Report
Tell the user the viewer is running and provide the URL (default: `http://localhost:3000`).
The viewer auto-refreshes when `.omm/` files change.
## Rules
- Always check for existing classes before starting the viewer
- If no classes exist, suggest `/omm-scan` instead of starting an empty viewer
- The viewer is read-only — it does not modify `.omm/` files
