Canessa System Labs · Community PlugIns

Free tools from Canessa System Labs for clear, governed work.

This repository is a plugin marketplace. Add it once to ChatGPT, Codex or Claude, and every Community PlugIn listed here becomes available to install. Each plugin brings one part of the Canessa System Labs method to your own projects, and runs its checks on your own machine.

Plugins

Plugin	What it does	Version
Morpheion Community	Turns ideas and plans into clear, print-ready documents: a preliminary analysis, an implementation plan or technical documentation, delivered as a Markdown draft and a protected PDF	0.1.0

Installation manual

Installing takes two steps on every host: add the marketplace (once), then install the plugin. The marketplace is this repository, Canessa-System-Labs/community-plugins; its name inside each host is canessa-system-labs-community.

Before you start

You need	Why	Check it
ChatGPT, Codex or Claude Code	The host that runs the skills	You can open it and start a chat
Node.js 24 or later	Runs the local quality check and builds the PDF	node --version prints v24 or higher
Chrome, Chromium, Edge or Brave	Renders the PDF on your machine	The browser opens normally

Without Node or a browser the skills still write the Markdown draft; they tell you the PDF was not made.

ChatGPT (workspace)

A workspace admin does steps 1–4 once; every member then does steps 5–6.

1. Sign in to ChatGPT as a workspace admin.
2. Open Admin → Plugins.
3. Select Add → Import marketplace.
4. Enter https://github.com/Canessa-System-Labs/community-plugins and select Import. Canessa System Labs · Community PlugIns appears in the list.
5. Members open the Plugins tab and find Morpheion Community.
6. Select + to install it, then start a new chat.

Codex CLI

codex plugin marketplace add Canessa-System-Labs/community-plugins

codex plugin add morpheion-community@canessa-system-labs-community

Start a new Codex thread so the plugin loads. If your Codex version names the commands differently, run codex plugin --help.

Claude Code (terminal or the Claude desktop app's Code tab)

1. In a Claude Code session, add the marketplace:

   /plugin marketplace add Canessa-System-Labs/community-plugins
   

2. Install the plugin:

   /plugin install morpheion-community@canessa-system-labs-community
   

3. Restart Claude Code (or start a new session) so the skills load.

Check that it works

Ask: "Use Morpheion Community to write a README for this repository." The skill drafts the document, checks it, and shows you a PDF to review. In Claude Code, /plugin also lists morpheion-community as installed.

Update or remove

Host	Update to the latest version	Remove
ChatGPT	Updates arrive when the admin refreshes the imported marketplace	Plugins tab → Morpheion Community → uninstall
Codex	Run the marketplace add command again	See codex plugin --help for the remove command in your version
Claude Code	/plugin marketplace update canessa-system-labs-community	/plugin uninstall morpheion-community@canessa-system-labs-community

If something goes wrong

What you see	What to do
The marketplace is not found	Check the address is exactly Canessa-System-Labs/community-plugins and that you can open it in a browser
The plugin is installed but the skills do not answer	Start a new chat, thread or session; hosts load skills at the start
You get the Markdown but no PDF	Install Node.js 24 and one of the browsers listed above, then ask the skill to render again
ChatGPT shows no Import marketplace option	Only workspace admins can import; ask yours
