What it does
Omm View is an agent skill from oh-my-mermaid/oh-my-mermaid. Start the omm web viewer to explore architecture diagrams in the browser. Use when the user says "omm view", "open viewer", "show diagrams", "view architecture", or "open architecture".
Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Diagrams. It works with Mermaid. The repository describes itself as: Turn complex codebases into clear, navigable architecture diagrams with Claude Code. The licence is MIT.
When your agent uses it
- The user says omm view
- View architecture
- Open architecture
Example prompts
- “omm view”
- “open viewer”
- “show diagrams”
- “/omm-view”
Requirements
- Node.js
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 38ccdb6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Omm View loads about 338 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 140 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:
command -v omm || npm install -g oh-my-mermaidIf 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
omm listIf no classes found, tell the user:
"No architecture docs found. Run /omm-scan first to generate them."
Then stop.
Step 2: Start the viewer
omm viewIf the user specified a port:
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-scaninstead of starting an empty viewer - The viewer is read-only — it does not modify
