What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

# 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

Questions

What does the Omm View skill do?

Turn complex codebases into clear, navigable architecture diagrams with Claude Code.

Is Omm View safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can Omm View access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

How current is this page?

The grade is for one exact copy of the source (a306c32c4012), read on 2026-10-09. The repository is watched, and a new audit runs when it changes — this is the first audit.
